Handmade speaker basic lecture �@
　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　Masao ida
　It is a basic lecture for making a handmade speaker.
　From a beginner, please also looking-obtain maniacs and enjoy
　a handmade speaker.
　It was made the English version so that he could also understand
　overseas one.　　　　　　　　　　　　　　　　
　
　
　　(1) The foundation of a handmade speaker

　(1) The Purchase of Parts of Handmade Speaker

　 A speaker unit, a capacitor, a coil, resistance, a terminal, a code
　The parts of go into a hand at part selling shops all over the country.
　Investigating by speaker-related books, a catalog, etc. is important.

　
................................................................................................................................................



　(2) Plywood Used for Handmade Speaker

　　　910mmx1820mm plywood is used.

　Textures, tone quality, and a tone get used to man, and a tree is a speaker
　box for many years.
　It has been used for Stability, such as intensity and expansion and contraction,
　was also excellent.
　It is structure and they are the China plywood, China ranbar core material, and
　particle board (wood).
　There is a thing MDF (nature fiberboard of inside) which hardened

　Being the inside and being used is the China plywood (laminating plywood of lauan)
　and China ranbar core material
　It is - core material (collection board of the small pure material of specific gravity).

　Both, on the surface of plywood, it is what stuck the white wood of wood, and is
　also grain.
　It is beautiful.

　 Research of sound and sound of lumber

　It was made reference from research of Mr. Toshio pro / Tanaka
　 lumber storekeeper
　Tanaka of lumber.
　Please look at [ what sound or ] whether it carries out by the difference in
　lumber.

　Kind Specific gravity Tendency of sound Processability
　Japan cedar 0.38 The heart is sound gentle to, although it is weak. Since it is soft,
　 it is careful.

　hinoki 0.41 tone quality and all tones -- mean it is cutting plane
　China ranbar core material bar core material 0.45 quiet intonation -- beautiful --
　being
　echoed -- cutting ease -- it is easy to process it
　lauan 0.6 the hinoki was made a little diffuse -- being echoed -- hard -- it is hard
　to process it

　China plywood 0.6 clear [ be / the heart / and ] -- being echoed -- cutting ease
　 -- it is easy to process it
　China runber plywood 0.62 a quantity region -- gay although it is easy to cut

　 MDF 0.65 Equivalent to rubber wood It is easy to cut and is hard to process it.
　Particle board 0.7 Equivalent to MDF Although it is easy to cut, it is petty
　processing difficulty.
　Rosewood 0.8 Sound which hardened the cherry tree Processing ease, chip
　cautions

　Kokutan 1 Sound which hardened the rosewood 〃
・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・


　Sound of a tree is related to specific gravity. A small tree tends to become
　sound without the heart.
　A large tree has the heart and becomes a clear sound.

　That is, in the smaller tree of specific gravity, Low sound vibrates on a grand
　 scale. Low sound in a box
　Although quantity is rich, it is hard coming to obtain the heart of sound. It is
　a board thick when using a Japan cedar and a hinoki.
　If it uses, tightness of Low sound will be achieved.

　A board stops being able to vibrate easily and the large board of specific gravity
　has a faithful motion of the oscillating version of a unit.
　It is alike and is reproduced. Sound has the heart, is clear and also has a feeling
　 of energy.

　However, resonance of a loud-sound region becomes strong, so that specific
　gravity becomes large.
　　　
　 The heart becomes a firm thing and, as for the tree of the degree of middle of
　specific gravity, Low sound, inside sound, and loud sound
　It is echoed with sufficient balance.

　　　　　　　　　　　　　　　　　　

　 Although the China plywood is this specific gravity belt, intensity is structurally
　 large, and sound is 0.6 or more.
　It is how to sound. Although it is hard board material, since laminating is carried
　 out to the China material, lauan material is also an appearance top.
　It is the material suitable for beautiful sound.

　Since heat pressure welding arrival is carried out as a feature, expansion by
　temperature and contraction are small, and sound is the heart.
　There is also a feeling of energy by the clearance with が. A speaker is turned
　to and it is a balun to all.
　It is the board material which was able to take

　 Although the heart material of the great portion of structure of China ranbar
　 core material is a tree with small specific gravity

　It is the plywood which only both sides gave intensity by collection of pure
　 material. I am D-58ES.

　Satisfactory also in respect of reproduction of a tone quality side and Super
　Low sound, although it is used for NessieJr
　It is carrying out.

　It is classically suitable by quiet intonation from especially pop and a jazz system.
　I consider. Moreover, a price can be made at a low price from the China plywood
　also in the field of a price.

　It is good China ranbar core material although it has pointed out that there is
　a cave in a certain explanatory.

　Core material does not those[ with a problem ] a cave. Heart material has what
　has high density.
　　　　　
　 Wood is a home center, although it is good and what has the beautiful seam
　 of joined boards is good.
　In a supermarket, it was not experience of a writer.

　Although the China plywood has been purchased in the home center, the white
　portion of Wood
　Not white but the quality of the material was not a uniform thing.

　It has a studio by silent は of new Koba in Tokyo, and the timber dealer. A cut
　is a large model.
　There is a cutting machine and the craftsman who has cut the speaker is working.

　Plywood [ being silent ] is high-quality, its density is high, Wood is white and its
　grain is also beautiful.

　　　Forster will be used if the rank of plywood is shown.


...............................................................
I cut and received all my speakers -- it is silent -- alike
　　　　　　I needed your help and board material cut service was begun .
　　　　　　　　　　　　　　　　　　

　* The handmade speaker which can be ordered in a network and which is
　　 made from a network!

　　　E-plywood cut service (20004. 2.10) opening was carried out.
　Please have a look more for details

. 　　　　　　　　　　　　　　　
...............................................................................................................................
.
　　
　Cautions of an assembly
　
　 In order to make grain live beautifully, they are a plan and checking about plywood.
　It is important to hold the image of completion.

　 The grain of cautions and 910×1820mm plywood is running in the direction of
　the grain of plywood horizontally.
　 The whiter one of Color becomes the surface and the more reddish one becomes
　 the back.
　Let's make work slowly without hurrying the point carefully.

　The bottom is the China plywood of a board. grain is running horizontally [ this ]
　Please observe.

　In the whiter one, a table becomes the one where the reverse side is more reddish.

　　　　

　 The plywood for work mainly uses 8mm in thickness, 15mm, 18mm, and 21mm.
...............................................................



　(3) View of Plan, and Turn of Assembly

　 Number (1) and (2) are shown in a plan. This is the same as the number of an
　assembly figure.
　the turn of the process which wrote the turn of an assembly for the board which
　 this number attached -- assembly

　In the inside of a process 4 and 5 which construct 1 to 2 in 1+2+3+ (4+5), and
　are constructed to 3 next
　After constructing and placing, it is a constructing [ with 3 ] meaning.

　If it does fundamentally as turn, it will be done automatically.
　The more nearly first one makes the part of each portion and assembles it into
　a big portion.
　Please think.




　　　　　 The example of an overly easy sealed type speaker
　　　　This is made

　　　　It is a plan.

　　　　　　　　　　　

　　　　A process is constructed in this turn.

　(4) Other Tools and Material

　 A bond uses the white bond for woodwork. The direction [ it does not use a nail ]
　 it is finished finely Nail causes It is divided.

　Since a bond is carried out for dozens minutes and becomes hard, it is not
　confused, but it checks four corners firmly.
　It carries out. It solidifies in 3 hours and pastes up completely in 6 hours. It
　does not move but is heavy.
　Since the adhesion effect goes up at least , please try.

　A sound-absorbing material is case-by-case, and is used. Sound will be lost if
　many [ too ].
　Many [ in / too ] is not good for sound. The direction [ it can hardly enter recently ]
　Many

　 Since the code for wiring and soldering are necessities, it is not a speaker cable.
　0. Code Which Can Recognize Plus and Minus by Red　White of 50 Diameters
　of 18Mm Etc. It is convenient.

　Three kinds are enough as sandpaper in a rude thing and a fine thing.

　what has the general pliers by the tool etc. -- it pastes up and money is used
　for fixed strengthening
　Accuracy can be raised by carrying out.

　In addition, the material (friend company of construction) of Kibe for repair etc
. is used.
............................................................



　(5) Terminal

　　　　　　As for the terminal of a terminal
　 　　　　　　the direction where the red mark is attached
　　　　　　　　　　　　　　　　　 becomes (+).

　　　　　　A black mark is (-). A connection code is choosing
　　　　　　　　what (+-'s) understands.
　　　　　　　　It can now mostly.


　(1) Fostex T100
　　　　　　　　　　　


　 T100 of large-sized gilding is usage with a plus and minus independent type.
　easy -- they are quality articles again T100 is the best as a terminal. Connection
　 code
　A potato's can be attached.

　The place in which that it is careful attaches a terminal with a speaker was decided.
　It is as a plan (there is also a thing without entry in inside), it is with a problem.
　It does not carry out.

　Usage is an alder about a connection code to the point of a terminal terminal,
　before connecting with a unit.
　attachment is carried out and it connects with a unit. A unit a connection code
　 [ the direction lengthened slightly ]
　It becomes easy to attach.

　8mm is suitable for the hole made in a board.



When connecting also with the main speakers or super Tweeter from
　a terminal
　T100 has the hole of connection (0-55mm), and it fixes it with the upper
　screw. Back load
　It is the terminal which is easy to use for a phon or a resonance pipe.

　 With E-board material cut service, I also do processing of the attachment hole
　 of a terminal.

　(2)Fostex T150B copper point-of-contact terminal
　　　　　　　　　　　


　　Fostex P24B speaker terminal
　　　　　　　　　　　
　　　　　
　In a small box, some which attached +- are in a plastic terminal board.
　This type is attached only by making two holes (12mm being suitable) in a
　back board.


　Although the upper photograph is T150B, the metallic ornaments which solder
　a　connection code to the bottom of a terminal board
　It is. There are this and a screw and it is a plastic immediately under a terminal
　board with a lower photograph further.
　If there is a cover (round shape) and these are united, a 12mm hole is required.
　
　　　　　　　　　　　　

　 Usage is solder about a connection code to metallic ornaments in the reverse
　side of a terminal board, before connecting with a unit.
　It is attaching and carrying out and letting a code pass from a hole. For a
　connection code, the direction lengthened slightly is about a unit.
　It -attachment-comes to be easy.
　It stops going into a hole in soldering inside these metallic ornaments, and outside.



Although there is no degradation of tone quality, since the hole is small
　　 to connection with super Tweeter
　　　　It is not suitable. It is a terminal suitable for the small box.

　　 With E-plywood cut service, I also do processing of the attachment hole
　　　of a terminal.

　(6) If Kiguchi Tape is Used

　　　　　　　　　　

　 If the Kiguchi tape is used, the place whose portion of the thickness of
　 a board can be seen can be hidden.


　 I used it for the super swan. Since the swan has imagined white
　If the Kiguchi tape is used, the black portion of a board will be lost, and it
　becomes a beautiful swan.

　Since the super swan at the time of manufacture was the conventional Kiguchi
　tape, it was pasted up.
　The portion of the thickness of the board an original swan is [ board ] a left
　photograph remains as it is.

　　　　　
　　　　Original super swan Super swan of the Kiguchi tape use
　　　　　　　The photograph of a super swan is from here.



　Kiguchi who sticks simply on a double-sided tape as a result of looking for the
　better Kiguchi tape There was a tape.
　　　
　The Kiguchi tape is attached not only when making a speaker from the start
　but after completion.
　The careful cautions it is made not to give a crack to a completion portion
　when cutting, although things are made
　 -- it is required

　　Please use as a makeup tape for finish. 　　

　　　　　　　　　　　　
　　　　　　　For a top, the Kiguchi tape / bottom is the China plywood.



　 I think that the same board as the China plywood is known like looking.

　 The Kiguchi tape is what used the China board as the tape by 1mm , and
　 the reverse side becomes a double-sided tape.
　It is, and if it removes, a required part can be pasted easily. Moreover, it is
　a woodwork bond to the both sides to stick.
　If the Kiguchi tape is stuck from It attaches, adhesion will become good more.

　 Usage
　There is no time and effort which will be cut if tape width is the same. It is
　 a gap when sticking a long distance.
　It takes care that there is nothing.

　In order to stick firmly to an angle more, the Kiguchi tape larger than the
　width to stick is used. It stuck.
　The rest drops the surplus portion on a cutter or sandpaper.

　If it polishes with sandpaper after sticking, it will be finished finely.

　The Kiguchi tape is stuck before an assembly and a part is polished with
　sandpaper together with a part.
　They are things. The Kiguchi tape will not be conspicuous, either, if it carries
　 out like this. Furthermore, it is the same as a surrounding paint.
　It is a thing and petty tape use completely is not clear anymore by applying.

　　　　　　　　　　　　　
　　　　　　If back paper is removed, it will become a double-sided tape.


　 Sale of the Kiguchi tape
　The China Kiguchi tape is sold with board material cut service.

　It becomes sale of 1m unit.
　 20mm width of 210 yen/m 　　 24mm width of 250 yen/m
　 26mm width of 280 yen/m 　　 35mm width of 390 yen/m
　 40mm width of 420 yen/m　　 42mm width of 480 yen/m

* 15mm China Kiguchi tape was added.

　By 15mm work, the time and effort which becomes completely the same
　 [ the Kiguchi width and tape width ]
　It is lost. However, it is warning against shifting, when sticking distance for
　 a long time.
　 21mm two-sheet pile becomes the same width no less than 42mm.

　It becomes sale of a 15mm China Kiguchi tape 1m unit.
　　　　　 15mm width of 160 yen/m

　Exclusive tape cutter It is the cutter cut with a ceramic sword according to
　an angle.
　It can use, if it gets used. There is also such a convenient cutter.

　　　　　　　　　　　　　　　Tape cutter corner (square shape)
　　　　　　　　　　　　　　　　　　　　　　　3,150 yen
　　　　　　　　　　　　　　　　



　 An order is from the price list of E-plywood cut service in an input to order form.
　　　　　　　　　　　Thank you for your consideration.

　(7) Speaker and Influence of Sound on Amplifier

　* The merit and target from full-range 1 of Mr. Nagaoka

　The demerit of a maker speaker system is size about the sound in low-pitched
　sound, and loud sound.
　It divides into the unit of smallness and a sound source is distribution and
　sound because of a still more complicated network.
　It is that freshness falls.

　 A from full range 1 is the device which makes low-pitched sound like a back
　 load phon.
　When a speaker is considered to be a musical instrument, the place blown, for
　example like a trumpet is small
　spreads gradually, the way of sound spreads, it becomes long, and a loud sound
　comes out.

　 Since low-pitched sound has from a unit the character around which it turns
　downward, the Takanaka sound is Sound Way
　 came out of the bottom.

　Furthermore, low-pitched sound comes out of a bottom more by making it heavy
　from a stone or a lead.

　　　　　　　　　　　　　
　　　　　　　　　　　　　　 A popular D-101S super swan


　 A super swan is the force which cannot consider at all although a unit is 10cm.
　　A certain low-pitched sound is reproduced.

　If I tell a super swan to the direction we wall carried out, the direction of 100%
　if low-pitched sound comes out like this why -- surprise surprise

　 Although it is a speaker and amplifier, the direction of the high amplifier of an
　 output with a price high naturally
　Tone quality becomes good. However, the unit of a handmade speaker
　As for a product, efficiency has some to which an output sound pressure level
　 exceeds　100dB highly.


　 It is the power of amplifier as a high speaker of the efficiency from the idea
　 from unit 1.
　It can use for full. Moreover, the power beyond the capability of amplifier can
　be pulled out.
　It is This neighborhood is the greatest merit of a its original work speaker.

　 The target of Mr. Nagaoka is its original work in which a maker speaker
　 is not lost　It aimed at making - car.
　And the back load phon and resonance pipe with which Mr. Nagaoka was now
　designed The speaker is made by many handmade speaker lovers.



* back load phon. phon is not making from the maker. a reason -- cost
　 -- extensive
　Although it is not being produced etc., a maker can make a speaker novel in fact.
　Probably, it will not be. If a tall boy has a large custom by the maker, it is the
　direction　　wholly.
　A flow is ridden and it is making.

　Handmade may be being able to perform a favorite thing.
　Moreover, a price of handmade is cheap and it is the highest that efficiency
　is made highly.

O This E-plywood cut service and E-speaker service are a handmade
　speaker.
　It lets you know, and it is managing in order to have you make to many directions.
　It is cheaper than others as much as possible, and it is carrying out so that it
　can provide kindly.

　　Me .... Masao Ida About

　Music was known with the handmade speaker.

　As a junior high school student, I hear tallthe back load phon. phon D-7 which
　the elder brother made, grow up, and am sound.
　It is , when the wonderfulness of beauty and music is known and a handmade
　speaker is made in when.
　It carried out now And it is making till present.

　Classical music takes to it more than especially these days, and it is Beethoven's
　 symphony
　A record is sufficient and ト Strauss's symphonic poem etc. was heard.

　a back load phon -- the softness of sound, sound of low-pitched sound, and
　junior and senior high schools -- the beauty of the sound of sound
　It taught and I took to music truly.

　Although the maniac who hears the sound of a speaker by the dreadfulness of
　a back load phon is also in regrettable one
　I feel joy for listening to music, although he also likes the uncanny sound.
　A great musician
　For example, Bach, Mozart, Beethoven, Brahms, Tschaikovsky, etc.
　There are many excellent pieces of music.

　If a biography is read and the history at the time is known, the background which
　the composer composed is known.
　If they are known, interest will boil to a musical piece further.

　Although it does not restrict classically but he also likes jazz and pop, back
　load phons are all.
　I regard a genre as it being in the wonderfulness which reproduces sauce to
　the degree of highest faithfully.

　　　　　　　　　　　　　　　　　　

　All super-Hi-Vision home theaters are handmade.

　 It becomes the time of AV now and the progress which exceeded the time
　ompared with ancient times acoustic reproduction technology
　It is. It places from a screen and the home theater using the handmade
　speaker is a stand.

　All were made from themselves. [ one ] A super-Hi-Vision home theater is
　an overly minute image and sound.
　It is the same sound as pure audio.

　The image by the big screen is recording the BS digital Hi-Vision program on
　videotape.
　A chic concert program is the pure audio itself, when it is a B-mode stereo.
.

　A handmade speaker can do sound of the home theater which is not made in
　maker make.

　Mr. Nagaoka is a 120 inches screen with which nobody is doing construction
　and those days.
　Surround is done by NessieIII and rear canon II. Also reproduction of pure audio
　Although it is uncanny, I regard that the teacher wanted to do as the home
　theater of a big screen.

　I am an arrangement and a liquid crystal projector for Hi-Vision about an old
　home theater.

　Since it changed to Hi-Vision correspondence, it considered as
　　　　　　 the super-Hi-Vision home theater.


　I am pleased, if it looking-gets, although it does not know whether to surely
　become helpful.

　　　　　　　　　　　　　　　　　　

　The unit got ES series.

　 Since ES series of Fostex was got, they are a super swan / Nessie
　It was very good that Jr.ES/D-58ES / rear canon II was able to be made.

　
About the speaker, although the homepage after completion was made
　　　　 it became a serious thing.

　 Make after completing this speaker, introduce a handmade speaker, and a
　 homepage .
　By the question or the visitor, is serious.

　It is present in the spread of the Internet that news become known to much
　[ early and information ] direction.
　The request and hope in the direction of looking at a homepage were known.

　For the reason, I make happily by the one [ want / to make a handmade speaker ]
　being the more nearly first.
　The handmade speaker basic lecture was made.

　As for sale / plywood cut of a unit, the request came from the reader.

　then, sale "E-speaker service" of a unit etc. -- further -- others --
　a board material 　　cut -- more

　As a result of considering it whether it can make it easy to be cheap and
　 to make early,　 it is the cut "E-board material cut service" of board material.


Until it will make 100 or more persons' speaker as of a start and December
　　　　in　February, 2004 It became.
　　　　　　　　　　　　　　　　　
　The handmade speaker and the home theater are actually used.


　　　　　　　　Please look at a homepage in the future.

　 A super-Hi-Vision home theater is description/connection of the equipments
　 which me am actually using.
　The method is carried. It also becomes the reference of the direction which
　wants to make a home theater.

　　　To the synthetic homepage which we recommend a handmade speaker to
　　　　many directions

　 For the directions which look at my homepage and are made for the first time
　 increasing in number, it is very glad.
　　I consider. Please give me a homepage well in the future pleasing.
