The present invention relates to a speaker, and more particularly, to a vibration coupling speaker coupling device, characterized in that to prevent vibration from being transmitted to electronic products by absorbing vibration generated from the speaker.

In general, an electronic product such as a television is accompanied by a speaker, thereby providing an image and sound to the user, usually located on both sides of the screen to provide sound.

On the other hand, recently, a speaker having a high output is being used as a high-quality large screen display is preferred.

1 is a diagram illustrating a coupling relationship between a front mask and a speaker of a conventional television.

Referring to FIG. 1, mounting portions 12 are formed at both rear surfaces of the front mask 11 forming the front surface of the television for installation of the speaker 15.

In this case, a plurality of bosses 13 protrude from the mounting part 12, and a coupling plate 17 having a coupling hole 16 corresponding to the boss 13 is formed in the speaker 15.

Therefore, the worker tightens the screw 18 to the boss 13 in a state where the boss 13 penetrates the coupling hole 16 of the coupling plate 17 to the mounting portion 12. The speaker 15 is fixed to be installed.

As can be seen from the above assembly state, in the past, the speaker was fixed simply by screws. As the speaker becomes high output, the coupling method cannot effectively absorb the shock caused by the high power of the speaker. It will cause its own shaking.

Accordingly, the present invention has been made in order to improve the above problems, the present invention is to provide a vibration reducing speaker to prevent the vibration phenomenon of the television itself, so that the vibration of the speaker is absorbed.

The present invention for achieving the above object is a case; An elastic part provided in the case and having its own elasticity; It is coupled to the elastic portion is coupled to provide a vibration reducing speaker coupling device comprising a sound generating unit for generating a sound.

The elastic portion is an elastic body of the 'S' shape is coupled to the case the bottom; It characterized in that it comprises a locking body protruding upward from the upper end of the elastic body and the end is hook-shaped.

The elastic body is characterized in that one side has a curvature.

The elastic part is characterized in that the injection molded integrally with the case.

End of the sound generating portion is bent and characterized in that seated between the elastic body and the locking body.

The guide bar penetrating the guide hole formed in the sound generating unit is characterized in that the case is provided.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the vibration reduction speaker coupling according to the present invention.

In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description.

In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to a user's or operator's intention or custom.

Therefore, definitions of these terms should be made based on the contents throughout the specification.

2 is an exploded perspective view of an acoustic generator and an elastic part according to an exemplary embodiment of the present invention, and FIG. 3 is a diagram illustrating an elastic part according to an exemplary embodiment of the present invention.

2 and 3, the case 40 of the electronic product is provided with an elastic portion 30, and the acoustic generator 20 is coupled to the elastic portion 30. The elastic unit 30 has its own elasticity to absorb the vibration of the sound generating unit 20 that the sound is generated.

The elastic part 30 includes an elastic body 31 and a locking body 32. The elastic body 31 has an approximately 'S' shape and retains its elastic force. The locking body 32 has a hook shape, and a part of the locking body 32 protrudes upward from the upper end of the elastic body 31. The elastic portion 30 is preferably designed so that the pair face each other.

Therefore, the sound generating unit 20 is located between the hook-shaped bottom surface protruding from the catching body 32 and the upper side of the elastic body 31 to maintain the state coupled with the case 40.

At this time, one side of the elastic body 31 has a curvature. That is, when the curvature surface 33 is formed on one side of the elastic body 31 facing each other, even if the elastic body 31 is deformed to the other side, the original state is quickly maintained by the restoring force.

The elastic part 30 may be injection molded integrally with the case 40 or may be combined with the case 40 by a separate combination not shown.

The end of the sound generating unit 20 is bent to form a bent surface 21. The bent surface 21 is a curvature is formed on the outer circumferential surface, so that the sound generating unit 20 is smoothly moved downward to the locking body (32).

On the other hand, the sound generating unit 20 is formed with a guide hole 25, the case 40 is provided with a guide bar 45 penetrating through the guide hole (25). The guide bar 45 and the guide hole 25 guide the sound generating unit 20 to be coupled to the elastic unit 30.

Referring to the coupling process of the sound generating unit and the case according to the present invention having the structure as described above are as follows.

After matching the guide hole 25 of the sound generating unit 20 with the guide bar 45 of the case 40, the sound generating unit 20 is moved to the elastic unit 30. At this time, the guide bar 45 passes through the guide hole 25, so that the sound generating unit 20 is guided to be coupled to the elastic unit 30.

On the other hand, in a state in which the bent surface 21 of the sound generating unit 20 is in contact with the upper end of the locking body 32, the operator pushes the sound generating unit 20 more strongly toward the elastic portion 30 direction. .

Then, the bent surface 21 is moved on one side of the locking body 32 and is located on the bottom surface of the locking body 32 and the upper surface of the elastic body 31.

At this time, the acoustic generator 20 is moved while the pair of elastic portions 30 are opened. When the elastic part 30 is returned to its original shape by the curvature surface 33, the end portion of the sound generating part 20 is located between the elastic body 31 and the locking body 32.

For this reason, even if there is no assembly work such as a separate screw coupling, the coupling of the sound generating unit 20 and the elastic unit 30 is completed.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand.

Therefore, the true technical protection scope of the present invention will be defined by the claims below.

As described above, the speaker coupling device for vibration reduction according to the present invention includes an elastic part having a self-elasticity in the case, and the acoustic generator is coupled to the elastic part to reduce the vibration of the acoustic generator.

For this reason, even if a high output speaker is used, the shaking phenomenon of the electronic product itself is prevented.

In addition, the vibration coupling speaker coupling device according to the present invention is coupled to the sound generating portion and the elastic portion through the hook coupling, there is an effect of simplifying the assembly process by removing the screw coupling.
