おいて実線Ｂで示すように、高域において大きなピーク
が発生し、音質が良好でない、という欠点があった。(Prior Art) Conventionally, as shown in FIG. 4, a speaker of this type is provided at an approximate center of a low-range sound reproduction speaker (hereinafter simply referred to as WF) through an X-shaped bridge 5 ', for example. (Hereinafter simply referred to as TW) is coaxially arranged, but TW4 'hinders the emission of sound of WF1', and a large peak is generated in a high frequency band as shown by a solid line B in FIG. And the sound quality is not good.
なお、第４図において、ブリッジ５′は単にTWを保持
するためのものである。In FIG. 4, the bridge 5 'is merely for holding TW.
（考案が解決しようとする課題） そこで、この高域のピーク、つまり音圧上昇を押さえ

いを設けたりしている。(Problems to be solved by the present invention) Therefore, in order to suppress the peak in the high frequency range, that is, the rise in sound pressure, the position of the TW is shifted from the center as shown in FIG. 5 or the balance is intentionally broken in front of the WF. Or to provide a cover.

果は充分ではないという課題があった。However, in the above configuration, the advantage of good localization of the coaxial sound image is lost, and WF
However, there is a problem in that the effect of suppressing the increase in the sound pressure is not sufficient because the balance of the vibrations is lost.
本考案は上記のことに鑑み提案されたもので、その目
的とするところは、WFのバランス損ねを防止し、かつ音
圧上昇を押さえ得る複合型スピーカを提供するにある。The present invention has been proposed in view of the above, and an object of the present invention is to provide a composite speaker capable of preventing loss of balance of a WF and suppressing an increase in sound pressure.

構成とすることにより、上記目的を達成している。(Means for Solving the Problems) The present invention is directed to a composite speaker in which a mid-high range reproduction speaker is provided substantially at the center of a low range reproduction speaker via a bridge. The bridge is formed in a substantially sector shape that is parallel to each other and is linearly symmetrical with respect to each of the X and Y axes that are orthogonal to each other, and that extends in width in the X-axis direction from the center toward the outer periphery.
The above object has been achieved by adopting a configuration in which each of the openings is symmetrical with respect to the X and Y axes within a range of 40% or less.
（作用） 上記のように、略扇形のブリッジを介してTWを中央に
設け、同軸型としているため、WFの振動板の振動のバラ
ンス損ねを防止している。(Operation) As described above, since the TW is provided at the center via the substantially fan-shaped bridge and is coaxial, the loss of vibration balance of the diaphragm of the WF is prevented.

The opening is formed in a range of 40% or less of the area.

ク成形品を使用すると好ましい。(Embodiment 1) FIGS. 1 (a) and 1 (b) show a first embodiment of the present invention, and show a coaxial composite speaker having an elliptical WF section. That is, reference numeral 1 denotes a WF, and the diaphragm 3 having the same shape is appropriately supported on the elliptical frame 2 via a damper, a gasket, or the like, as is well known. Reference numeral 4 denotes a TW portion located at a substantially central portion of the WF1, and for example, a cone type speaker, a dome type speaker, a piezoelectric type speaker or the like is used. This TW4
Supports the bridge 5 substantially coaxially. The bridge 5 is preferably made of a plastic molded article integrally formed with the frame 6 of the TW4.

範囲でX,Y軸に対して線対称に開口させている。Thus, this bridge 5 is parallel to the WF opening plane,
In addition, it is line-symmetric with respect to each of the X axis corresponding to the short axis and the Y axis corresponding to the long axis, and is formed substantially in a fan shape in the X axis direction, and has a range of 40% or less of the bridge area. The aperture is opened symmetrically with respect to the X and Y axes.

Further, the opening area with respect to the bridge area is about 30%, but the optimum opening area and its position are selected within the range of 40% or less according to the size of the speaker as described above.

る。In this case, the TW4 is provided at a substantially central portion of the WF1 via the bridge 5, but X and Y which are parallel to the opening surface of the WF1 and are orthogonal to each other.
Since the bridge 5 is formed symmetrically with respect to each of the axes and substantially in a fan shape, and is opened symmetrically with respect to the X and Y axes within a range of 40% or less of the bridge 5, the WF1 has its vibration. The balance of the vibration of the plate is not impaired, and the bridge 5 that covers a part of the WF1 has a substantially fan-like shape, which has an effect of extremely suppressing a rise in sound pressure. That is, FIG. 2 shows the sound pressure characteristics with respect to frequency, where A is the present invention and B is a conventional example, and the present invention prevents a high-frequency peak.

In this embodiment, a round composite speaker is used, and an opening 5b of each bridge 5 extends in the Y-axis direction. It has a shape like a substantially rectangle. That is, the side on the TW4 side is curved along the shape of the TW4, the opposite side is straight, and the corners are rounded.

It has a substantially fan-shaped shape that extends in the axial direction, and the TW is placed at the center of the fan, and it is opened within 40% or less. Since the TW position does not deviate from the center, the vibration balance of the WF diaphragm is balanced. Without damaging it, it is possible to suppress a high-frequency peak by a substantially fan-shaped bridge, and to prevent a decrease in sound pressure level by an opening provided in the bridge.
