BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to an auxiliary fastening device for assisting in fastening a transducer on a base structure and, more particularly, to an auxiliary fastening device capable of isolating a vibration induced during the operation of the transducer.

2. Description of the Prior Art

Most of transducers, e.g. a speaker, make noise and induce vibration during operation.

When a transducer, e.g. a speaker, makes noise during operation, the transducer will do a linear reciprocating movement, and the sound wave generated by the transducer may induce the resonance phenomenon of sound.

With the poor design of the support and fastening structure of the transducer, when the transducer makes noise during operation, the normal linear reciprocating movement of the transducer will be interfered; as a result, it may induce the deformation in the transducer itself or in the parts of the support and fastening structures.

Moreover, when the transducer makes noise during operation, the sound wave generated by the transducer and the related components of the support and fastening structure of the transducer may induce the resonance phenomenon of sound to affect the quality of sound.

In order to solve the above mentioned problems, some inventions have been disclosed. For examples, U.S. Pat. Nos. 5,682,021, 5,956,412, 6,654,472, 6,744,903, 6,760,460, and 6,990,212.

Both the first main bodies21have a first formed-trough fastening hole22and a second formed-through fastening hole23. The position of the second fastening hole23is symmetrical to the position of the first fastening hole22. And, the transducer20can be a speaker.

The first preferred embodiment based on the invention is an auxiliary fastening device10including a second main body11, a first boss12, and a second boss13.

The second main body11is made of a shock-absorbing material, and the second main body11is capable of being fastened on the base structure (not shown inFIG. 1andFIG. 2).

The first boss12is made of the shock-absorbing material and protruded from the second main body11. And, the first boss12is corresponding to the first fastening hole22and its structure fits the corresponding first fastening hole22. Besides, the first boss12also has a respective free end121and a respective bonding end122in a form of a retainer.

In an embodiment, when the first fastening hole22which is corresponding to the first boss12is fit for the bonding end of the first boss12, the first fastening hole22will clamp the bonding end of the first boss12.

In an embodiment, the shock-absorbing material can be a rubber or a polymer material.

The second boss13is protruded from the second main body11. And, the second boss13is corresponding to the second fastening hole23and its structure fits the corresponding second fastening hole23.
