る。 Hereinafter, the configuration of the present invention will be explained based on FIG. 2, which is an embodiment thereof. In the figure, 1 is a full plate, 2
is the entire speaker, and 3 is the speaker frame. The speaker mounting hole 4 of the full board 1 is formed with a tapered surface 4a so that the diameter becomes smaller as it goes outward, and the outer surface of the frame 3 is formed with a tapered surface 3a that is symmetrical to the above-mentioned tapered surface 4a. has been done. Therefore, a trapezoidal wedge fitting groove 5 is formed by the tapered surface 4a and the tapered surface 3a of the speaker mounting hole 4 described above. Reference numeral 6 denotes a cylindrical back cavity with a bottom, and a flange portion 7 is formed at the opening edge of the back cavity, and tapered surfaces 7a and 7b corresponding to the tapered surfaces 3a and 4a are formed on the inner and outer surfaces of the flange portion 7. is formed so that the flange portion can be press-fitted into the wedge fitting groove 5. When installing the back cavity 6, after fitting the flange portion 7 into the wedge fitting groove 5, bolts are tightened at positions dividing the speaker mounting flange 2b provided around the outer periphery of the speaker frame 2. By tightening the bolts 8, the flange portion 7 is press-fitted into the wedge fitting groove 5, and the speaker frame 3,
The flange portion 7 and the full plate 1 are firmly fixed. In addition, back cavity 6
is located inside the speaker enclosure, so to prevent it from falling into the speaker enclosure during assembly, the presser plate 9 is screwed to the back of the buttful plate 1 to prevent the back cavity 6 from falling. I'm starting to do that.

ある。 According to the speaker mounting structure of the present invention, the speaker mounting hole of the buttful plate is formed with a tapered surface so that the diameter becomes smaller toward the outside, and the outer surface of the speaker frame is opposite to the tapered surface. has a tapered surface that is symmetrical to the tapered surface, and a wedge fitting groove is formed between both tapered surfaces, and a flange portion that fits into the wedge fitting groove is formed on the opening edge of the back cavity. is formed, and the flange portion is fitted and held by the fastening means, so the back cavity and the speaker can be firmly fixed to the back full plate, preventing the occurrence of resonance and improving the sound quality. You can improve your performance. Additionally, when the temperature of the speaker frame rises, the flange expands, making the speaker frame even more securely attached.
It has excellent features such as being able to handle continuous large inputs.
