Description of the Related Art As a technique for mounting a speaker of this type, Japanese Patent Application No. 03-048302 discloses a technique for fixing a cylindrical electromagnet portion on the bottom surface of the speaker by press fitting it into a mounting hole. There is. In addition, actual application 02-
Japanese Patent No. 0226646 discloses a structure in which a flange portion of a speaker is elastically held by a pair of holding walls in the radial direction and the thickness direction. However, any of these methods may cause various problems in actual mass-production assembly due to a narrow allowable range for dimensional variation of the flange portion of the speaker and insufficient fixing force due to pressing.
FIG. 5 is an exploded perspective view showing a conventional general speaker mounting structure. As shown in FIG. 5, the speaker 102
An annular wall 106 is formed at the mounting position of the inside of the opening 104, and the annular wall 106 is sandwiched between, for example, 2
A boss 108 is erected at the location. Then, the speaker 102 is arranged on the annular wall 106 so as to cover the opening 104 and the annular wall 106, and in this state, the lower end portions of the two metal fittings 109 are brought into contact with the rear surface 112 of the flange portion 110 at the front end of the speaker 102. And each metal fitting 109 is fixed to each boss 108 with a screw 114, and the flange 110
The speaker 102 is attached in a state where the back surface 112 is pressed by the metal fitting 109. An unillustrated ring made of paper is attached to the front surface of the flange portion 110 of the speaker 102, and the lower surface of the ring is in close contact with the upper surface of the annular wall 106 when the speaker is attached.

【発明が解決しようとする課題】しかし、このような従
来の取り付け構造には次のような問題点がある。第１の
問題点は、金具１０９により少数箇所でスピーカ１０２

ということである。そのため、スピーカ１０２の振動部
であるコーン紙１１６が変形してしまい、音割れや音の
ビリツキなどの音質の劣化、音量の低下を引き起こす結
果となる。However, such a conventional mounting structure has the following problems. The first problem is that the metal fitting 109 allows the speaker 102 to be installed in a small number of places.
That is, the force is partially applied to the flange portion 110 of the speaker 102 in order to fix the above, and the flange portion 110 is distorted. As a result, the cone paper 116, which is the vibrating portion of the speaker 102, is deformed, resulting in deterioration of sound quality such as sound cracking and flicker of sound, and a decrease in volume.

じやすくなる。The second problem is that the ring-shaped body made of paper material provided on the front surface of the flange portion 110 of the speaker 102 has a relatively large variation in thickness. That is, it may be difficult to fix them easily. That is, when the ring of paper material is thin, the pressing force of the metal fitting on the flange portion 110 is insufficient and rattling occurs. On the contrary, when the ring is thick, the pressing force of the metal fitting is too large, resulting in the above-mentioned problem. The flange 110 is likely to be distorted.

コスト高となる。The third problem is that the assemblability is poor. That is, at the time of assembly, the speaker 102 is first placed on the annular wall 106, and then the metal fittings 109 are arranged.
Must be placed on the boss 108 and the flange portion 110, the screw 114 must be inserted into the screw hole of the metal fitting, and then the screw 114 should be screwed and fixed to the boss 108 by a driver.
Work efficiency is poor. Further, the degree of distortion of the flange portion 110 changes due to the variation in the degree of tightening of the screws 114, and the fixing condition of the speaker 102 also changes. Therefore, there is a demand for improvement in keeping the quality of the product constant. Furthermore, if the screws are not tightened properly, the work must be redone, resulting in an increase in the number of work steps.
High cost.

取り付け箇所に押圧されるように構成されている。In order to achieve the above object, the present invention provides a ring body for accommodating a speaker inside and mounting the speaker at a speaker mounting position substantially coaxially with the speaker, and the ring body for the speaker. It is configured to include a fixing means for fixing to a mounting location. The annular body includes a tubular portion having an inner diameter larger than that of the flange portion at the tip of the speaker, and a plurality of elastic materials protruding from a portion spaced apart in the circumferential direction of the tubular portion toward the center of the tubular portion. It has a fin part and a plurality of claw parts which are provided in the peripheral face of the above-mentioned cylinder part at intervals in the peripheral direction, and which project outside in the radial direction of the cylinder part. The fixing means includes a plurality of hook portions that are provided at the speaker mounting portion and that engage with the claw portions to fix the ring body to the speaker mounting portion.
Then, when the claw portion is engaged with the hook portion of the fixing means to fix the ring body to the speaker mounting portion, the back surface of the flange portion of the speaker is biased by the fin portion, The front surface of the portion is configured to be pressed to the speaker mounting portion.

れた状態となって、スピーカが固定される。In the speaker mounting structure of the present invention, when mounting the speaker, the speaker is placed at the speaker mounting position, and in this state, the speaker is placed inside and the ring is covered from the back side of the speaker to the ring. The claw portion on the outer peripheral surface of the ring body is engaged with the hook portion provided at the speaker mounting position to fix the ring body. As a result, the back surface of the flange portion of the speaker is urged by the lower surface of the fin portion of the ring body, and the front surface of the flange portion is pressed against the speaker mounting portion, so that the speaker is fixed.

数を削減してコストダウンを図ることが可能となる。The fins can be arranged at sufficiently narrow intervals in the circumferential direction of the annulus, so that the flange of the speaker is uniformly urged by the fins over the entire circumference. As a result, the distortion of the flange portion unlike the conventional case does not occur, and the sound quality is not deteriorated due to the deformation of the cone paper, such as sound cracking and flicker, and further, the volume is not lowered. Further, when the speaker mounting structure of the present invention is used, even if there is some dimensional variation in relation to the flange portion of the speaker, the entire flange portion can be pressed uniformly by the fin portion, which causes rattling. It is possible to avoid the occurrence of the occurrence of a force and a partial excessive force applied to the flange portion. Furthermore, since there is no need for screwing work like in the past, the problem of variation in tightening force does not occur and it is effective in maintaining a constant product quality.
Since it is unnecessary to redo the mounting work, it is possible to reduce the number of work steps and reduce the cost.

数を削減してコストダウンを図ることが可能となる。The fins can be arranged at sufficiently narrow intervals in the circumferential direction of the ring body, so that the flange of the speaker is uniformly urged by the fins over the entire circumference. As a result, the distortion of the flange portion unlike the conventional case does not occur, and the sound quality is not deteriorated due to the deformation of the cone paper, such as sound cracking and flicker, and further, the volume is not lowered. Further, when the speaker mounting structure of the present invention is used, even if there is some dimensional variation in relation to the flange portion of the speaker, the entire flange portion can be pressed uniformly by the fin portion, which causes rattling. It is possible to avoid the occurrence of the occurrence of a force and a partial excessive force applied to the flange portion. Furthermore, since there is no need for screwing work like in the past, the problem of variation in tightening force does not occur and it is effective in maintaining a constant product quality.
Since it is unnecessary to redo the mounting work, it is possible to reduce the number of work steps and reduce the cost.
