る。(b) Prior art When conventionally mounting a flat speaker on a speaker panel, a boss 1a is provided on the speaker panel 1 as shown in Fig. 3, and a screw 3 is inserted into a through hole (not shown) in the frame 2a of the speaker 2. , the frame 2a is fastened to the boss 1a. Therefore, since the length of the boss 1a is required to be longer than the length of the screw 3, the speaker panel 1 comes out in front of the flat diaphragm 2b, and a cavity 10 surrounded by the speaker panel 1 is created. Therefore, interference occurs between the sound that goes forward of the flat diaphragm 2b and the sound that travels along the flat diaphragm 2b and is reflected on the speaker panel 1 and goes forward (so-called cavity effect), resulting in sound pressure characteristics. As a result, the characteristics of the flat speaker are lost.

There are also flat-plate speakers that suppress the disturbance of characteristics caused by the cavity effect.

The figure is also a side sectional view showing the state after installation.
The speaker panel 1 has a substantially rectangular opening 1c and an opening 1.
A substantially rectangular frame portion 1d is provided around c. The frame portion 1d is formed at a constant height from the back surface 1e of the speaker panel 1 over the entire circumference, and mounting portions 1f are provided at four locations on the outside of the frame portion 1d.
The mounting portion 1f is composed of a positioning piece 1g and a boss 1a having a screw hole 1h. Furthermore, on the outside of the frame 1d, there are two protrusions 1i across each corner.
One guide piece 1k is provided on each side.

様の効果をあげることができる。 Next, insert the positioning piece 1g of the speaker panel 1 into the through hole 4d and notch 4e of the bracket 4 for positioning, and align the screw insertion hole 4c of the bracket 4 with the screw hole 1h provided in the boss 1a of the speaker panel 1. . In this way, the flat part 2f provided on the frame 2a of the speaker 2 will be sandwiched between the frame part 1d of the speaker panel 1 and the clamping part 4a of the bracket 4, so tighten the screw 3 and tighten the bracket 4.
When the mounting portion 4b of the speaker panel is attached to the mounting portion 1f of the speaker panel, the speaker 2 is held between the speaker panel 1 and the bracket 4, and the front surface 2 of the flat diaphragm 2b is
c and the front surface 1b of the speaker panel 1 form a substantially continuous plane. It should be noted that the present invention can achieve the same effect by using a plurality of screws as the mounting members instead of the bracket 4 and screwing them into screw holes as the mounting portions.

圧特性の良好な平板スピーカが得られる。(g) Effects of the invention By making the front surface of the flat diaphragm of the speaker and the front surface of the speaker panel substantially continuous, it is possible to suppress disturbances in characteristics due to the cavity effect. Furthermore, since the edges around the diaphragm are covered by the periphery of the opening of the speaker panel, no sound is reflected by the edges, and disturbances in characteristics due to the cavity effect can be suppressed. Therefore, a flat speaker with good sound pressure characteristics can be obtained with a simple configuration.
