Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a component mounting device, and more particularly to a component mounting device suitable for mounting a component that easily vibrates, such as a speaker, to a cabinet that requires airtightness.

Conventionally, as shown in FIG. 1, a speaker box is known in which a speaker 3 for mid-bass sound and a speaker 4 for high-pitched sound are fixed to a front baffle plate 2 of a cabinet 1. For example, the treble speaker 4
is fixed to the buttful plate 2 at four locations with screws 5, but in order to maintain airtightness and vibration isolation, the second
As shown in the figure, a spacer 6 having elasticity is inserted. The spacer 6 is made of paper or urethane, and serves to maintain airtightness by preventing air from flowing out and inflowing into the cabinet 1, and to cause the speaker 4 to vibrate differently from the buffer plate 2 due to external vibrations. It is arranged to provide an anti-vibration effect to prevent abnormal noise from being generated due to contact between the speaker 4 and the full plate 2.

However, using a special part called the spacer 6 in order to maintain the airtightness and vibration isolation is disadvantageous in terms of workability and cost, and the elasticity of the spacer 6 deteriorates over time. As a result, it has been extremely difficult to maintain desired characteristics over a long period of time.

The present invention has been developed in view of the above-mentioned points, and it is an object of the present invention to provide a component mounting device with excellent airtightness and vibration-proofing properties without using special spacers. An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 shows an embodiment of the present invention, in which 7 is a buttful plate disposed at the front of the cabinet, and 8 is attached to the buttful plate 7.
The speaker is mounted and fixed with screws 9.
The speaker 8 includes a frame 8a made of metal or synthetic resin, and an arcuate rib 8b whose center height is higher than the heights at both ends, which are integrally formed on the back surface of the frame 8a. There is. Therefore, when the screw 9 is screwed together in order to attach and fix the speaker 8 to the buffer plate 7, the ribs 8b dig into the surface of the buffer plate 7, and the buffer plate 7
The surface of the frame 8a of the speaker 8 is in close contact with the back surface of the frame 8a. Therefore, the air inside the cabinet does not flow out to the outside or flow in from the outside, and sufficient airtightness can be maintained.

FIG. 4 is for explaining the shape of the speaker more clearly, with A showing the back of the speaker and B showing the side. Thus, in FIGS. 4A and 4B, the rib 8b is formed in a rectangular shape along the periphery of the rectangular frame 8a, and screw holes 10 for mounting are bored in the four corners of the rectangular frame 8a. has been done. The rib 8b has a fourth rib 8b.
As shown in FIG. As they are fitted together, the ribs 8b bite into the buttful plate, and the amount of biting into the center portion 8c, which has the largest width, becomes larger, and the stress in the center portion 8c becomes the maximum, so that the back surface of the frame 8a covers the entire circumference. It crosses over and comes into close contact with the surface of the buttful plate 7 to maintain airtightness, and
Since the speaker is strongly fixed to the buttful plate by the stress, there is an advantage that the vibration damping effect is improved.

In the embodiment, a case has been described in which a speaker having a frame is attached to the speaker cabinet, but the present invention can also be applied to a case where an attenuator or the like having a frame is attached to the speaker cabinet. Furthermore, the present invention can be used not only for speaker cabinets, but also for installing components in cabinets that require airtightness and vibration-proofing effects, just like speaker cabinets. I can do it.

As described above, the present invention can achieve excellent airtightness and vibration isolation without using special spacers, so it is a practical device that allows parts to be mounted at low cost and with good workability. The ribs are arched with a high central part, and when both ends of the ribs of the frame are attached and fixed with screws, the stress in the central part of the frame is maximum, so the parts are firmly fixed to the cabinet, and the parts are firmly fixed to the cabinet. This has the advantage of improving the vibration isolation effect of parts.
