Description

Technical Field

[0001] This invention relates to a loudspeaker with vibration damping function, and more particularly to a design that absorbs the kinetic energy of vibration from the loudspeaker unit by setting a vibration damping ring. Background Technology

[0002] Almost all consumer electronics products, such as mobile phones, tablets, and laptops, must be equipped with speakers to produce sound. A speaker actually consists of a speaker driver and a speaker enclosure. The speaker driver is the main sound-producing unit, which is installed inside the speaker enclosure to form the speaker, and then finally assembled into the end consumer electronics product (such as a laptop). However, because the speaker driver is directly connected to the speaker enclosure when it operates, it causes the entire speaker to vibrate. This vibration is then transmitted to the entire laptop, causing the laptop's casing to resonate. This not only causes discomfort for the user but also results in a significant amount of resonant noise, making people feel uncomfortable. Summary of the Invention

[0003] The main technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art and provide a loudspeaker with vibration damping function, which has the effect of absorbing the vibration kinetic energy from the loudspeaker unit by setting a vibration damping ring; and has the effect of improving the vibration damping effect by the hollow structure of the vibration damping ring.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A loudspeaker with vibration damping function includes: a loudspeaker driver; a speaker enclosure having an opening relative to the loudspeaker driver; and a damping ring made of a damping material, wherein the inner ring surface of the damping ring is engaged with the periphery of the loudspeaker driver, the outer ring surface of the damping ring is engaged with the opening wall of the opening, and the damping ring has an upper support portion and a lower support portion protruding from the inner ring surface, the upper support portion being attached to the top surface of the loudspeaker driver, and the lower support portion being attached to the bottom surface of the loudspeaker driver.

[0006] Furthermore, the loudspeaker unit is rectangular and includes: a support, a diaphragm, a voice coil, and a magnetron structure. The support has an annular flat-top joint. The diaphragm has a suspension portion and an annular planar joint surrounding the suspension portion, the annular planar joint being joined to the annular flat-top joint. The damping ring is rectangular, with an upper support portion forming upper lugs at each of the four corners of the damping ring, and these upper lugs having a clearance distance relative to the outer edge of the suspension portion, resulting in the annular planar joint being fully or partially exposed. The lower support portion forms lower lugs at at least two of the four corners of the damping ring. The lower support portion also forms support bodies on each of the two long sides of the damping ring. The damping ring is made of foamed plastic, rubber, or silicone. Preferably, the damping ring is made of rubber or silicone with a Shore A hardness between 40 and 10, preferably rubber or silicone with a Shore A hardness of 20.

[0007] Furthermore, the damping ring has a hollowed-out structure to enhance the damping effect; wherein, the hollowed-out structure is an upper recessed area and a lower recessed area formed inward from the outer ring surface of the damping ring, and a platform body is formed between the upper recessed area and the lower recessed area, and several dome ribs are formed upward from the platform body, and the opening of the speaker also has an annular abutment part, which abuts against the top edge of the dome ribs, and the dome ribs are equidistantly distributed.

[0008] Alternatively, the hollow structure can be a number of deep recesses formed inward from the outer ring of the damping ring. The opening of the speaker also has an annular abutment portion that abuts against the outer side of the top surface of the damping ring. The abutment portion is located above the recesses. The recesses are a series of alternating upright and inverted triangular recesses.

[0053] First, please refer to Figures 1-6 As shown, the first embodiment of the present invention includes: a loudspeaker unit 10; a speaker enclosure 20 having an opening 21 relative to the loudspeaker unit 10, the opening 21 also having an annular abutment portion 22; and a damping ring 30a made of foamed plastic material, rubber or silicone, preferably rubber or silicone with a Shore A hardness between 40 and 10 degrees (preferably 20 degrees), the inner ring surface 31 of the damping ring 30a is attached to the periphery of the loudspeaker unit 10, the outer ring surface 32a of the damping ring 30a is attached to the opening wall 211 of the opening 21, an upper abutment portion 33 protruding from the inner ring surface 31 is formed on the inner side of the top surface of the damping ring 30a, the upper abutment portion 33 is attached to the top surface of the loudspeaker unit 10, and a lower abutment portion 34 protruding from the inner ring surface 31 is formed on the bottom surface of the damping ring 30a, the lower abutment portion 34 is attached to the bottom surface of the loudspeaker unit 10.

[0054] Furthermore, the loudspeaker unit 10 is rectangular and includes: a support 11 having an annular flat-top joint 111; a diaphragm 12 having a dome 121, a suspension portion 122 surrounding the dome 121, and an annular planar joint 123 surrounding the suspension portion 122, the annular planar joint 123 being joined to the annular flat-top joint 111, the area of ​​the annular flat-top joint 111 being greater than or equal to the area of ​​the annular planar joint 123; a voice coil 13 being joined at the junction of the dome 121 and the suspension portion 122; and a magnetic return structure 14 being joined to the support 11 and having a relative position to the voice coil 13. There is a magnetic gap; the damping ring 30a is rectangular, and the upper support portion 33 forms an upper lug 331 at each of the four corners of the damping ring 30a, and the upper lugs 331 have a clearance distance relative to the outer edge of the suspension portion 122, so that the annular planar joint portion 123 is partially or completely exposed, so as to prevent the upper lugs 331 from contacting the suspension portion 122. The lower support portion 34 forms a lower lug 341 at at least two of the four corners of the damping ring 30a; wherein, the lower support portion 34 also forms a support body 342 on each of the two long sides of the damping ring 30a.

[0055] Furthermore, the damping ring 30a also has a hollowed-out structure 35a to enhance the damping effect. The hollowed-out structure 35a consists of an upper recessed area 351 and a lower recessed area 352 formed inward from the outer ring surface 32a of the damping ring 30a. A platform body 353 is formed between the upper recessed area 351 and the lower recessed area 352. Several equidistant dome ribs 354 are formed upward from the platform body 353. The top edges of these dome ribs 354 abut against the abutting part 22 of the speaker 20. The heights of these dome ribs 354 may be equal or unequal. Therefore, the several equidistant dome ribs 354 have the following advantages: 1. They reduce the contact area between the damping ring 30a and the speaker 20, thereby reducing the vibration energy transmitted to the speaker 20; 2. They increase the strength of the damping ring 30a, preventing the structure of the damping ring 30a from being too soft.

[0056] Next, please refer to Figures 7-11As shown, the second embodiment of the present invention includes: a loudspeaker unit 10; a speaker enclosure 20 having an opening 21 relative to the loudspeaker unit 10, the opening 21 also having an annular abutment portion 22; and a damping ring 30b made of foamed plastic material, rubber, or silicone, preferably rubber or silicone with a Shore A hardness between 40 and 10 degrees (preferably 20 degrees). The inner ring surface 31 of the damping ring 30b is attached to the periphery of the loudspeaker unit 10, and the outer ring surface 32b of the damping ring 30b is attached to the opening wall 211 of the opening 21. An upper abutment portion 33 protruding from the inner ring surface 31 is formed on the inner side of the top surface of the damping ring 30b, and the upper abutment portion 33 is attached to the top surface of the loudspeaker unit 10. A lower abutment portion 34 protruding from the inner ring surface 31 is formed on the bottom surface of the damping ring 30b, and the lower abutment portion 34 is attached to the bottom surface of the loudspeaker unit 10.

[0057] Furthermore, the damping ring 30b is rectangular, and the upper support portion 33 forms an upper lug 331 at each of the four corners of the damping ring 30b. The upper lugs 331 have a clearance distance relative to the outer edge of the suspension portion 122, so that the annular planar joint portion 123 is partially or completely exposed, thus preventing the upper lugs 331 from contacting the suspension portion 122. The lower support portion 34 forms a lower lug 341 at at least two of the four corners of the damping ring 30b. The lower support portion 34 also forms a support body 342 on each of the two long sides of the damping ring 30b.

[0058] Furthermore, the damping ring 30b also has a hollowed-out structure 35b to enhance the damping effect. This hollowed-out structure 35b consists of several deeply recessed cavities 355 formed inwards from the outer ring surface 32b of the damping ring 30b. The outer top surface of the damping ring 30b abuts against the abutting portion 22 of the speaker 20, and the abutting portion 22 is located directly above these cavities 355. These cavities 355 are continuously and alternately arranged upright and inverted triangular cavities, forming a truss-like structure. The upper edge of these cavities 355 extends to the damping ring 30b... The top surface has an upper edge thickness h, and the lower edge of the recesses 355 to the bottom surface of the damping ring 30b has a lower edge thickness H. There is a gap thickness w between the recesses 355. The lower edge thickness H is greater than the upper edge thickness h, and the gap thickness w is close to the upper edge thickness h. Preferably, the lower edge thickness H is more than twice the upper edge thickness h. Therefore, the thinner upper edge thickness h can increase the deformability of the damping ring 30b and reduce the vibration energy transmitted to the speaker 20. The thicker lower edge thickness H is used to strengthen the strength of the damping ring 30b and prevent the damping ring 30b from undergoing excessive deformation.

[0059] However, before the damping rings 30a and 30b are combined with the speaker unit 10, adhesive is applied to the mating surfaces of the upper support portion 33 and the lower support portion 34. After the damping rings 30a and 30b are combined with the speaker unit 10, adhesive is applied to the seam between the top surface of the damping rings 30a and 30b and the top surface of the speaker unit 10; adhesive is also applied to the seam between the outer ring surfaces 32a and 32b of the damping rings 30a and 30b and the opening wall 211 of the opening 21.

[0060] Based on this configuration, the present invention combines damping rings 30a and 30b between the speaker driver 10 and the speaker enclosure 20. Through the damping characteristics of the damping rings 30a and 30b themselves, the vibrational kinetic energy from the speaker driver 10 is absorbed (dissipated), preventing the vibrational kinetic energy from being further transmitted to the speaker enclosure 20 structure, thus achieving the purpose of vibration reduction. It has the effect of absorbing the vibrational kinetic energy from the speaker driver by setting up damping rings. In addition, the damping rings 30a and 30b also have hollowed-out structures 35a and 35b to further enhance the vibration reduction effect. The hollowed-out structures 35a and 35b are all located on the outside of the damping rings 30a and 30b (not a transverse design), and do not destroy the integrity of the inner ring surface 31 of the damping rings 30a and 30b. It can maintain the strength of the damping rings 30a and 30b and absorb the vibrational energy of the speaker driver 10 over a large area. It also has the effect of improving the vibration reduction effect through the hollowed-out structure of the damping ring.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
