閉鎖している。On the front side of the frame 5, there is an edge 5b that is folded back inward.
and an L-shaped baffle plate holding arm 18 at a predetermined interval.
A holder 19 consisting of a gouge 11 having a U-shaped cross section is fitted into the gap between the arm I8 and the edge 5b. The peripheral edge of a l-plate-shaped wood board 9 is fitted into the holder 19, and the opening on the front side of the frame 5 is closed with the wood board 9.

生しないと共に、外観が改善される利点がある。On the inner surface of the notches $9a and 9b19c of the wood board 9, there is a diaphragm l011 of the speaker unit 14.15.1G.
1 and I2 are installed as shown in FIG. Since these diaphragms 101If and 12 are made of thin wood plates, they are made of straight-grained material with a thickness of 1 to 2 mm (2 m rn in the embodiment), and the straight-grained surface is exposed on the surface. The thin wood board may be a veneer or plywood; plywood has higher rigidity and is less likely to break. Incidentally, instead of straight-grained wood, board-grained wood may be used, and the surface of the material may be exposed. The thin wood board mentioned above may be a softwood material such as Sitka spruce, which has excellent acoustic properties, or a hardwood material such as zelkova, which has a specific gravity of 0.
.. 25 to 0.8 is preferably used. In addition, in order to prevent these thin wood boards from warping, the OHJti (hydroxyl groups) in the wood are chemically treated, such as by etherification or esterification, and the thin wood boards are chemically modified.
-, there will be no expansion and contraction due to humidity, and no warping will occur. Furthermore, instead of the chemical modification mentioned above, if synthetic resin is injected into the surface layer of the thin wood board and treated with WPC, dimensional stability will be improved, humidity changes will be small, only warping will occur, and the appearance will be improved. There is an advantage that

ル板として作用する木材数9にも用いていてもよい。In the WPC processing, a thin wood board is placed in a vacuum/pressure g8, and after the air inside the board is removed by vacuum, plastics such as polyester and polystyrene are injected under pressure.
It is preferable to absorb 30 to 40% of the electricity inside the wood and harden it with hardened sand. J-Foot Wood whose hydroxyl groups have been chemically treated and whose surface layer has been treated with synthetic resin are used not only for diaphragms 10, 11, and 12, but also for 1. It may also be used for the number 9 pieces of wood that act as baffle plates.

A honeycomb material 21 is attached with an adhesive at an interval of 1 to 2 n'l rn from the peripheral edge. The S4 honeycomb material 21 is made of aluminum honeycomb, which is lightweight and has high strength, and its thickness is set to 3 to 5 nm. Note that the 1γ thickness of the honeycomb 9 should not be made too large.
The above-mentioned thickness is preferable because -F is undesirable because it causes resonance, and if it is too small, the strength will be poor. As the honeycomb material 21, paper honeycomb or FI(I) honeycomb may be used instead of the aluminum honeycomb. A skin 22 made of the same material is adhered to the back side of the honeycomb material 21 with adhesive, and the skin 22 made of aluminum 11
When using honeycomb, an aluminum skin is used. The skin 22 works to improve the strength to some extent and to maintain the shape of the honeycomb material 21, but it is not necessary.
There is no need to provide one.

One end of a down-type edge material 23 is fixed with an adhesive to the peripheral edge of the back surface to which No. 1 is not attached. As shown in the figure, the down-type edge material 23 has a curved shape on the back side, and one end surface 23 protruding toward the front side is attached to the back side of the thin wood board, and the curved edge 23b is attached to the notch of the wood board 9. It is adhesively fixed between the back surface of the periphery and the frame 24 of the speaker unit, so that the surface of the diaphragm 101II, +2 does not protrude from the wood board 9 and forms a flat surface.

該木材板9を振動させる。A wooden speaker with the above structure! To explain the operation of the speaker unit! When the speaker units 14, 15, and 16 are driven to reproduce sound, an audio current signal flows from the molding 132 to the voice coil 31 in each speaker unit 14, 15, and 16, and the voice coil 31 and the coil winding frame 30 are activated in accordance with the signal. vibrates, and along with the vibration, the flat diaphragm 10.11 vibrates via the support 29, thereby reproducing sound. In this way, when the speaker units 14, 15 and 1G are driven, the diaphragms IO1+1, 12 vibrate and sound is reproduced,
The reproduced sound is radiated forward and backward, and the sound radiated backward is reflected by the rigid board 13 and reaches the wood board 9 on the front side.
The wooden board 9 is vibrated.

スピーカと同様の効宋が得られる。Since the wood board 9 is attached to the frame 5 via a holder 19 made of rubber, it can easily absorb vibrations 4 independently from the frame 5.
-ru. The wood board 9 is larger than the diaphragms 10-12, and has speaker units 14-16 attached thereto, so it resonates with sounds in the low frequency range and can reproduce low frequencies. Therefore, since it is a 3-way type speaker equipped with three speaker units I-1.1 to 16, it can provide the same effect as a 4-way speaker.

記に列挙する効果を有する。As is clear from the explanation by Takahi Ishikawa, according to the present invention, the speaker uses an east-facing moving plate to make it thin, allows it to be embedded in a wall, and the front side facing the room is made thin. It is composed of a wood board with a wood grain pattern and a flat diaphragm, so that it does not feel strange even when exposed on a wall surface, and a decorative panel with the same shape and pattern as the surface of the speaker is provided. Since the wall surface is constructed by connecting the speaker to the speaker, it has the following effects.
■壁面にスピーカを埋め込むことが出来るので、部屋の
空間を広く使用することが出来る。■Since the speakers can be embedded in the wall, the space in the room can be used more widely.
■見掛け、ヒ、同様の化粧パネルと連設セることで、ス
ピーカの存在を認識出来ないようにしζいるため、違和
感の無い空1用を構成出来る。■Apparently, by connecting it with a similar decorative panel, the presence of the speaker can be made unrecognizable, so it is possible to configure a natural-looking sky 1 display.

ることが出来、意匠効果が優れたものとなる。■The wood on the surface of the speaker ÷ O Since a one-section plane diaphragm is placed, the plane diaphragm acts as an accent of the decorative ball on the wall, and the shape, position, size, etc. of the plane diaphragm is By selecting it appropriately, it is possible to give a novel impression that has not been seen before, and the design effect becomes excellent.
■スピーカを壁面の高い位置に設置することが出来るた

ムラなく音を聴くことが出来る。■Since the speakers can be installed high on the wall, the sound can be heard evenly from any position in the space without any sound barriers such as furniture.

きは小さい程、音のズレが生じることなく再生できる。■In the structure of the speaker itself, the wooden board that was conventionally fixed to the front side of the frame was attached to the frame so that it could vibrate, and by using a thin and lightweight material, the reflection from the rigid plate on the back side was improved. By actively vibrating the sound and the reflected sound inside the speaker, it can act as a baffle plate, especially a sound plate in the low frequency range. From this point of view, the smaller the depth of the speaker, the more the sound can be reproduced without any distortion.

く、埋め込んで設置することが出来る乙のである。Therefore, in addition to using a flat diaphragm as the diaphragm of the speaker unit, the depth of the speaker can be reduced, and the speaker can be installed embedded in a thin wall without protruding. I can do it.
