Description

[Detailed Description of the Invention] The present invention relates to a speaker mounting device.

Conventionally, to attach a speaker to a frame, the rear part of the speaker is fitted into a hole made in a plate placed on a pillar of the frame to hold the speaker, and a retaining plate is used to hold the collar of the speaker using screws. This was done by screwing the plate together with the pillar of the frame. This resulted in disadvantages such as an increase in the number of parts and the complicated work of screwing in screws.

In the present invention, the elastic leg piece of the mounting spring body is inserted into the gap between the collar of the speaker and the locking pawl of the locking part protruding from the frame body by its elastic force. By configuring it to apply downward pressing force to the parts, the number of parts is reduced.
To provide a speaker mounting device that does not require screws for mounting and is easy to install.

An embodiment of the present invention will be described with reference to FIGS. 1 to 4. The lower surface of the flange portion 2 of the speaker 1 projects from the frame 3 and is in contact with the upper surface of supporting portions 4 and 5 that are positioned opposite to each other with the speaker 1 in between, thereby holding the speaker. Locking parts 6 and 7 having locking claws 6a and 7a are provided to protrude in a direction perpendicular to the direction in which the supporting parts 4 and 5 face each other. , 7a are provided at the upper part of the flange part 2 with a gap therebetween and extend toward the center of the speaker with a slight upward inclination. A positioning protrusion 8 protrudes from the frame 3 on the outside of the speaker collar 2. The positioning protrusion 8 is used to position a speaker mounting spring body 9, which will be described later, and has a stepped portion 8a and a shaft portion 8b provided at its tip.

As shown in the third figure, the speaker mounting spring body 9 is made of an elastic material such as piano wire and curved into an ohm shape, and is provided with a base 9a that is positioned by a positioning protrusion 8. Elastic leg pieces 9b and 9c extend in an arc shape. This elastic leg piece is an operating part 9d provided at both ends of the spring body 9.
By compressing the flange portion 2 and the locking portion 6,
7 into the gap by its outward elastic force. In addition, as shown in the fourth figure, the elastic leg pieces 9
b and 9c are curved in an arcuate manner in the plane direction of the collar portion 2. That is, due to the inclined shape of the locking parts 6, 7 and the arcuate shape of the elastic legs, when the elastic legs enter between the locking parts 6, 7 and the collar part 2, the outward restoring force is applied to the elastic legs. Therefore, by engaging the locking claws 6a, 7a, a pressing force is applied to the elastic leg pieces 9b, 9c in the surface direction of the collar portion 2. In this example, the flange portion 2 is pressed with the above-described configuration, but the slanted shape of the locking portion or the arcuate shape of the elastic legs may be used to ensure that sufficient pressure is applied to the flange portion 2. It may be set to apply a certain pressing force.

Figures 5 to 7 show other examples of mounting spring bodies,
The structure of the frame is the same as the above example. Mounting spring body 1
Reference numeral 9 is made by bending and curving an elastic plate that has been pressed into a substantially U-shape, and is bent 90 degrees on both sides of the base 19a through which the positioning protrusion 8b passes, and then curved into an arc shape. Elastic leg piece 19
b, 19c. The tips of both legs are provided with operating portions 19d that allow easy compression of the legs. As shown in FIG. 7, the side surfaces of the elastic leg pieces are formed in an arcuate shape, so that the pressing force against the collar portion 2 is ensured.

Attachment spring body 29 showing other examples shown in 8th and 9th figures
In this case, a base portion 29a, elastic leg pieces 29b, 29c, and an operating portion 29d are formed by pressing an elastic plate into the planar shape shown in FIG. .

Therefore, in order to attach the speaker 1, place the collar part 2 of the speaker 1 on the support parts 4 and 5, and then attach the base parts 9a, 19a,
29a is positioned by the positioning protrusion 8, and the operation parts 9d, 19d, 29d are compressed inward, and the elastic leg pieces 9b, 9c or 19b, 19c or 29b,
The locking claws 6a, 7a of the locking portions 6, 7 have 29c.
The compressive force of the operating part is loosened so that it enters the gap between the flange part 2 and the flange part 2. When the elastic leg piece enters the gap, its outward restoring force causes the locking claw 6
an elastic piece 19 formed into an arched shape with the inclined surfaces of a and 7a;
When b and 19c are engaged, a downward pressing force is applied to the flange portion, and thus the speaker 1 is pressed against the support portions 4 and 5, and rattling is eliminated in the installed state. Furthermore, when removing the speaker, the attached spring body can be removed by simply compressing the operating portions 9d, 19d, and 29d.

As described above, according to the present invention, the holding part and the locking part are integrally formed in the frame, and the mounting spring body elastically enters between the locking claw and the collar of the locking part. It has a simple configuration, has a small number of parts, does not require mounting screws, and can be installed easily and at low cost. Further, when the speaker is installed, a force is applied to press the speaker against the support portion, and the speaker does not vibrate when producing sound, so that the sound can be improved. In both of the embodiments described above, the positioning means for the spring body 9 is constituted by a positioning protrusion 8 protruding from the frame body 3 and a positioning hole 9a provided in the spring body 9 that fits into the positioning protrusion 8. However, the positioning means is not limited to the above-mentioned configuration; for example, it is also possible to position using the arcuate portion of the spring body 9; It can be selected as appropriate depending on the shape.
