Description

Speaker vibration damping structure

The present invention relates to a vibration-damping structure for a speaker, and in particular to a vibration-damping structure for a speaker that can enhance the vibration-damping effect.

General electronic products (such as mobile phones, tablets, laptops, etc.) all need to be equipped with speaker modules to produce sound, and the speaker module is usually composed of a speaker unit and a speaker box. The speaker unit is the main sound unit and is installed behind the speaker box to become a speaker module. It is then assembled into consumer electronic products with a buffer pad.

However, when the speaker unit is in motion, it will cause the entire speaker module to vibrate. Although the speaker module is equipped with a buffer pad to dampen vibration, the speaker module will still transmit the vibration to the entire electronic product. Therefore, when the speaker module is in motion, the electronic product will resonate with it, which will not only cause discomfort to the user, but also cause a considerable degree of resonance and abnormal sound, making people feel uncomfortable, and thus causing defects in use.

Therefore, how to invent a vibration-damping structure for a speaker to prevent the vibration of the speaker from being transmitted to electronic products and generating abnormal sounds, thereby achieving an enhanced vibration-damping effect and effectively improving the shortcomings of usage, will be what this invention actively discloses.

In view of the above shortcomings of the prior art, the inventor felt that it was not perfect, so he devoted all his energy to research and overcome it, and then developed a vibration-damping structure for the speaker, which can be assembled between the speaker and the electronic product to serve as a buffer and regulator when the speaker resonates, so as to avoid the vibration of the speaker being transmitted to the electronic product and generating abnormal sound, thereby achieving the effect of improving the vibration-damping effect.

To achieve the above and other purposes, the present invention provides a vibration damping structure for a speaker, which includes: a vibration damping locking part, an elastic arm and a speaker assembly part. The vibration damping locking part includes a locking hole; the elastic arm is arranged on the vibration damping locking part; the speaker assembly part is arranged on the elastic arm, and the vibration damping locking part and the speaker assembly part are respectively arranged at two ends of the elastic arm.

In the above-mentioned vibration-damping structure of the speaker, the vibration-damping locking part, the elastic arm and the speaker assembly part are formed of a soft material in one piece.

In the above-mentioned vibration-damping structure of the speaker, the hardness of the vibration-damping structure of the speaker is 20 degrees to 80 degrees.

In the above-mentioned vibration-damping structure of the speaker, the hardness of the vibration-damping structure of the speaker is preferably 50 degrees to 60 degrees.

In the vibration-damping structure of the above-mentioned speaker, the elastic arm includes a plurality of upper semicircular protrusions and a plurality of lower semicircular protrusions, and the cross-section of the elastic arm is wavy.

In the vibration-damping structure of the above-mentioned speaker, the upper semicircular protrusions and the lower semicircular protrusions are arranged in the same position, or the upper semicircular protrusions and the lower semicircular protrusions are arranged in a staggered position.

In the above-mentioned vibration-damping structure of the speaker, the speaker assembly part includes a set of connection holes and an anti-fool buckle body, the set of connection holes is arranged between the elastic arm and the anti-fool buckle body, and the anti-fool buckle body has a flat surface and a convex surface.

In the above-mentioned vibration-damping structure of the speaker, the speaker is provided with a convex buckle body, an engaging groove and a cover body, the assembly hole of the speaker assembly part is assembled with the convex buckle body, the speaker assembly part is assembled with the engaging groove with the convex surface of the foolproof buckle body, and the cover body closes the speaker assembly part and abuts against the plane of the foolproof buckle body.

In the above-mentioned vibration-damping structure of the speaker, the speaker assembly part is formed integrally with the speaker.

In the above-mentioned vibration-damping structure of the speaker, the ratio of the width of the vibration-damping locking part to the width of the elastic arm is 1:0.5~1:0.8.

In the above-mentioned vibration-damping structure of the speaker, the ratio of the thickness of the vibration-damping locking part to the thickness of the elastic arm is 1:0.4~1:0.6.

In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific embodiments and the attached drawings, as follows:

Please refer to Figures 1 to 6, as shown in the figures: The present invention provides a vibration-damping structure 1 for a speaker, which includes a vibration-damping locking part 11, an elastic arm 12, and a speaker assembly part 13.

The vibration-damping locking portion 11 includes a locking hole 111.

The elastic arm 12 is disposed on one side of the damping lock portion 11.

The speaker assembly part 13 is disposed on one side of the elastic arm 12, and the damping lock part 11 and the speaker assembly part 13 are disposed on two ends of the elastic arm 12 respectively.

When the vibration damping structure 1 of the speaker of the present invention is assembled (as shown in Figures 3 to 5), the speaker assembly part 13 can be assembled to a speaker 2, and the vibration damping locking part 11 can be assembled to the screw hole of the fixing column 31 of an electronic product 3 (for example: mobile phone, tablet, notebook computer, etc.) by using its locking hole 111 and a fixing element 112 (such as a screw). After the assembly is completed, the elastic arm 12 can be located between the speaker 2 and the electronic product 3, and when the speaker 2 resonates, the elasticity of the elastic arm 12 can be used as a buffer and adjustment for the resonance of the speaker 2 to prevent the vibration of the speaker 2 from being transmitted to the electronic product 3 and generating abnormal sound, thereby achieving the effect of enhancing the vibration damping.

Based on the description of the above embodiment and FIG. 6 , it can be seen that the vibration-damping structure 1 of the speaker of the present invention can greatly improve the vibration-damping effect compared to the conventional buffer pad, and effectively acts as a buffer and regulator when the speaker 2 resonates, so as to prevent the vibration of the speaker 2 from being transmitted to the electronic product 3 and generating abnormal sound.

In addition to the above-mentioned embodiments, in one embodiment of the present invention, the damping lock part 11, the elastic arm 12 and the speaker assembly part 13 can be formed of a soft material in one piece, for example, the damping lock part 11, the elastic arm 12 and the speaker assembly part 13 can be formed of a silicone material in one piece. In this way, the damping structure 1 of the speaker can not only be easy to manufacture, but also have better structural strength, so that it can be stably assembled between the speaker 2 and the electronic product 3, so as to truly serve as a buffer and regulator when the speaker 2 resonates.

In addition, the top and bottom surfaces of the vibration-damping lock part 11 can be provided with a plurality of protrusions 113, respectively, and the protrusions 113 are located around the lock hole 111. Thus, when the fixing element 112 is assembled to the fixing column 31 of the electronic product 3, the bottom surface of the fixing element 112 can touch the protrusions 113, which can not only ensure that the vibration-damping lock part 11 is fixed, but also prevent the fixing element 112 from excessively squeezing the vibration-damping lock part 11 to cause deformation, thereby preventing the vibration-damping lock part 11 from loosening or displacement due to long-term vibration of the speaker 2.

In addition to the above-mentioned embodiments, in one embodiment of the present invention, the elastic arm 12 may include a plurality of upper semicircular protrusions 121 and a plurality of lower semicircular protrusions 122. The upper semicircular protrusions 121 and the lower semicircular protrusions 122 make the cross section of the elastic arm 12 wavy, and the upper semicircular protrusions 121 and the lower semicircular protrusions 122 may be arranged in a staggered manner. In this way, the elastic arm 12 may have better structural strength and elasticity, so as to be stably assembled between the speaker 2 and the electronic product 3, so as to truly serve as a buffer and regulator when the speaker 2 resonates.

In addition to the above-mentioned embodiments, in one embodiment of the present invention, the speaker assembly 13 may include a set of connection holes 131 and an anti-fool buckle body 132, the set of connection holes 131 is arranged between the elastic arm 12 and the anti-fool buckle body 132, the anti-fool buckle body 132 is provided with a flat surface 1321 and a convex surface 1322; in addition, the speaker 2 may be provided with a convex buckle body 21, an engaging groove 22 and a cover 23.

Based on the above-mentioned embodiment, when the vibration damping structure 1 of the speaker box of the present invention is assembled with the speaker box 2, the assembly hole 131 of the speaker box assembly part 13 can be assembled with the convex buckle body 21, and the speaker box assembly part 13 can be assembled with the convex surface 1322 of the foolproof buckle body 132 with the engaging groove 22, and then the cover body 23 is used to close the speaker box assembly part 13 and abut against the flat surface 1321 of the foolproof buckle body 132. In this way, the vibration damping structure 1 of the speaker box can be stably assembled with the speaker box assembly part 13 and the speaker box 2, and the speaker box assembly part 13 forms a sealed state, so as to prevent the internal gas of the speaker box 2 from leaking from the position of the speaker box assembly part 13 to the outside of the speaker box 2, causing the problem of sound quality distortion. In addition, the vibration damping structure 1 of the speaker of the present invention can also prevent the vibration damping structure 1 of the speaker from being placed upside down during assembly by means of the foolproof buckle body 132 of the speaker assembly part 13.

In addition to the above-mentioned embodiments, in one embodiment of the present invention, the speaker assembly part 13 of the vibration damping structure 1 of the speaker can be integrally formed with the speaker 2 by double injection. In this way, the vibration damping structure 1 of the speaker can be stably assembled with the speaker 2 by the speaker assembly part 13, and the speaker assembly part 13 can be sealed to prevent the internal gas of the speaker 2 from leaking from the position of the speaker assembly part 13 to the outside of the speaker 2, causing the problem of sound quality distortion.

In addition to the above-mentioned embodiments, in one embodiment of the present invention, the hardness of the vibration-damping structure 1 of the speaker can be 20 degrees to 80 degrees. For example, the material of the vibration-damping structure 1 of the speaker can be a silicone material with a hardness of 20 degrees to 80 degrees, preferably a silicone material with a hardness of 50 degrees to 60 degrees; the ratio of the width of the vibration-damping locking part 11 to the width of the elastic arm 12 can be 1:0.5~1:0.8; the ratio of the thickness of the vibration-damping locking part 11 to the thickness of the elastic arm 12 can be 1:0.4~1:0.6. In this way, the vibration-damping structure 1 of the speaker can have better structural strength and support, so that it can be stably assembled between the speaker 2 and the electronic product 3 to effectively serve as a buffer and regulator when the speaker 2 resonates.

Please refer to Figures 7 and 8. As shown in the figures, in addition to the above-mentioned embodiments, the difference between this embodiment and the above-mentioned embodiments is that the upper semicircular protrusions 121 and the lower semicircular protrusions 122 of the elastic arm 12 are arranged in the same position, which can also make the cross-section of the elastic arm 12 wavy. In this way, the elastic arm 12 can meet different application requirements and also has better structural strength and elasticity, so as to be stably assembled between the speaker 2 and the electronic product 3, so as to truly serve as a buffer and regulator when the speaker 2 resonates.
