Description

[Detailed Description of the Invention] The present invention relates to a speaker system in which a single piece of damping material is used to prevent the protector from becoming loose, the baffle plate to be damped, and interference distortion caused by speaker vibration to be prevented.

BACKGROUND ART Conventionally, a speaker system configured as shown in FIG. 1 has been widely known in order to prevent the protector from becoming loose and to prevent the occurrence of interference distortion due to vibration of the speaker.

This has projecting edges 3 for attaching a protector to the four peripheral edges of the cabinet 1 on the side of the baffle plate 2, and a speaker 6 is attached around the through hole 4 of the baffle plate 2 with screws 5.

Further, the bent locking piece 8 of the protector 7 fitted into the projecting edge 3 is stuffed with a rubber ring 9, etc., and is stably held within the projecting edge 3. The generation of rattling noise is prevented.

Further, a buffer member 11 is interposed between the frame edge 10 of the speaker 6 and the baffle plate 2 that supports the frame edge 10 to prevent interference and distortion caused by the speaker 6 from occurring.

However, in such a speaker system, the structure for preventing vibration and interference distortion is complicated, and the work of attaching the speaker 6 and protector 7 using backings of different shapes and sizes is complicated. The drawback was that the workability was extremely poor.

The present invention aims to improve the five disadvantages of the conventional structure and work. In particular, by using a single piece of damping material, it not only prevents the protector from becoming loose and interferes with distorted noise, but also The purpose of the present invention is to provide a new speaker system that can easily brake and stably hold a baffle plate.

Embodiments of the speaker system according to the present invention will be described below with reference to the drawings.

FIG. 2 shows one embodiment of the present invention, and is a plan view showing the main parts cut away, in which 12 is a cabinet and 13 is a baffle plate.

On the four peripheral edges of the cabinet 1 on this baffle plate 13 side,
Stepped notches 14 and 15 are formed for attaching a sash frame and a protector, which will be described later.

Further, the baffle plate 13 is provided with a sound emission hole 16 for a speaker, and a continuous braking plate 17 is pasted on almost the entire front surface of the baffle plate 13 excluding the sound emission hole 16 and on the side surface of the notch 14. It is installed by methods such as arranging.

As the brake plate 17, a cushioning material such as felt or molten plain is cut out to an appropriate size and used.

18 is a speaker attached to the baffle plate 13, and its frame edge 20 is attached to the brake plate 17 by screws 19.
It is fixed to the baffle plate 13 via.

A sash frame 21 supports the four circumferences of the protector 22, and these frames are fixed by screws or other methods.

These fixed and integrated components are connected to the cabinet 12 by fitting the locking piece 23 of the protector 22 into the notch 14 via the brake plate 17.

In this case, the sash frame 21 is engaged with the notch 15.

Note that, if necessary, the series of brake plates described above can be extended between these to prevent unnecessary vibrations between them.

According to this configuration, the brake plate 17 is connected to the protector 22.
Since the protector 22 is supported with respect to the cabinet 12 in a cushioning manner, it is possible to prevent rattling noise from occurring due to unnecessary vibrations generated between the protector 22 and the cabinet 12.

Furthermore, the damping plate 17 is also interposed between the speaker 18 and the baffle plate 13 that supports it, and effectively prevents diffraction and reflection of sound waves generated in this part, air conditioning resonance, and interference distortion. It is possible to improve the acoustic characteristics.

Furthermore, since the braking plate 17 is laid over almost the entire surface of the baffle plate 13, it is possible to obtain a braking effect on plate vibration of the baffle plate 13.

As described above, in the present invention, the front surface of the baffle plate is covered with a damping material, a part of which is interposed between the speaker and the baffle plate to which this is attached, and the damping material is extended to the side surface of the baffle board. By cutting out a brake plate, bending it, and laying it on the baffle plate, the speaker protector is elastically held on the side surface of the cabinet. At the same time, it is possible to prevent the generation of rattling noise that occurs in the speaker, damp the baffle plate, and prevent interference distortion noise that occurs between the speaker and the baffle plate.

In addition, since the work and structure for this purpose are extremely simple, it is highly practical.
