2. Description of the Related Art

A conventional loudspeaker typically has a magnetic member usually provided in the form of a single-magnet structure. The magnetic member is fixedly fitted to a speaker base of the loudspeaker. There is not any design of a buffer between the speaker base and the magnetic member. As a result, the vibration of the loudspeaker in operation is directly transmitted to a casing of an electronic device on which the loudspeaker is mounted, causing discomfort to persons using the electronic device.

DETAILED DESCRIPTION OF THE INVENTION

To facilitate understanding of the object, characteristics and effects of the present disclosure, embodiments together with the attached drawings for the detailed description of the present disclosure are provided.

Referring to FIG. 1 through FIG. 4, the first embodiment of the disclosure provides a vibration damping loudspeaker comprising a sound-generating unit 1, a magnetic member 2, an assembly-auxiliary frame 3 and a plurality of dampers 4.

The sound-generating unit 1 comprises a speaker base 11, a diaphragm 12 and a voice coil 13. The speaker base 11 has a plurality of positioning units 17. The diaphragm 12 is disposed at the top of the speaker base 11. The voice coil 13 is connected to the bottom of the diaphragm 12.

The magnetic member 2 comprises a main magnetic plate 21 and a magnetic unit 22. The magnetic unit 22 is disposed on the top surface of the main magnetic plate 21. The voice coil 13 is movably disposed outside the magnetic unit 22. The magnetic unit 22 has a magnet 221 and a magnetic plate 222 which are stacked up.

The assembly-auxiliary frame 3 has a plurality of aligning units 35 and is disposed outside the magnetic member 2. The aligning units 35 are coupled to the positioning units 17 respectively to allow the assembly-auxiliary frame 3 to be mounted on the bottom of the speaker base 11. The assembly-auxiliary frame 3 and the speaker base 11 are coupled together by high-strength plastic elements to enhance assembly stability to preclude reliability issues, such as fall-induced failure. The aligning units 35 are coupled to the positioning units 17 by a rugged structure respectively.

The dampers 4 are symmetrically disposed between the main magnetic plate 21 and the assembly-auxiliary frame 3. In an embodiment of the disclosure, the dampers 4 are in the number of two (not restrictive of the disclosure), and the dampers 4 are made of rubber or silicone, with silicone hardness being 40 to 60 degrees, preferably 60 degrees. The dampers 4, the main magnetic plate 21 and the assembly-auxiliary frame 3 are integrally formed by injection molding.

The process of the assembling the vibration damping loudspeaker entails coupling the assembly-auxiliary frame 3 and the speaker base 11 together by the aligning units 35 and the positioning units 17 to preclude deviations of the sound-generating unit 1 and the magnetic member 2 relative to each other to allow the sound-generating unit 1 and the magnetic member 2 to be quickly and easily mounted in place to enhance the production yield. During its operation, the vibration damping loudspeaker can be coupled to an acoustic enclosure (not shown) to allow the voice coil 13 of the sound-generating unit 1 to receive external electronic signals such that the main magnetic plate 21 and the magnetic unit 22 of the magnetic member 2 coordinate with each other to provide more magnetic energy to allow the voice coil 13 to coordinate with the electromagnetic effect of the magnetic member 2 to drive the diaphragm 12 vibrating, increasing the sound volume of the vibration damping loudspeaker in operation.

During the operation of the vibration damping loudspeaker, owing to the assembly-auxiliary frame 3 and the dampers 4, the absence of direct contact between the speaker base 11 of the sound-generating unit 1 and the magnetic member 2 allows the dampers 4 to function as a buffer between the speaker base 11 and the magnetic member 2 to not only absorb (consume) the kinetic energy generated from the vibration of the speaker base 11 but also preclude the reverse transmission of the kinetic energy generated from the vibration of the magnetic member 2, so as to achieve vibration damping and vibration isolation during the operation of the vibration damping loudspeaker to spare users the discomfort they will otherwise experience for using electronic devices. With the dampers 4 functioning as a buffer between the speaker base 11 and the magnetic member 2, the magnetic member 2 and the speaker base 11 have similar vibration frequency but opposite phases, further enhancing vibration damping.

In addition to the aforesaid embodiments, an embodiment of the disclosure has technical features as follows: two long-side sides of the main magnetic plate 21 each have a longitudinal long-side magnetic plate 212; two short-side sides of the main magnetic plate 21 each have a transverse short-side magnetic plate 213; the assembly-auxiliary frame 3 is disposed outside the bottoms of the longitudinal long-side magnetic plates 212 and the transverse short-side magnetic plates 213; the dampers 4 are symmetrically disposed between each of the transverse short-side magnetic plates 213 and the corresponding one of the two short-side sides of the assembly-auxiliary frame 3; and the voice coil 13 is movably disposed between the longitudinal long-side magnetic plates 212 and the magnetic unit 22. The longitudinal long-side magnetic plates 212 are integrally formed with the main magnetic plate 21. The transverse short-side magnetic plates 213 are integrally formed with the main magnetic plate 21. Therefore, the vibration damping loudspeaker of the disclosure is advantageous in that the dampers 4 are symmetrically disposed on two short-side sides of the magnetic member 2 and adapted to function as a buffer between the speaker base 11 and the magnetic member 2 to not only absorb (consume) the kinetic energy generated from the vibration of the speaker base 11 but also preclude the reverse transmission of the kinetic energy generated from the vibration of the magnetic member 2, so as to achieve vibration damping and vibration isolation during the operation of the vibration damping loudspeaker to spare users the discomfort they will otherwise experience for using electronic devices.

In addition to the aforesaid embodiments, an embodiment has technical features as follows: the dampers 4 each have a plurality of first fitting portions 45, the assembly-auxiliary frame 3, and the transverse short-side magnetic plates 213 each having at least a second fitting portion 2133; the first fitting portions 45 of the dampers 4 are fitted to the assembly-auxiliary frame 3 and the second fitting portions 2133 of the transverse short-side magnetic plates 213 respectively to couple together the magnetic member 2, the assembly-auxiliary frame 3 and the dampers 4 such that the first fitting portions 45 coordinate with the second fitting portions 2133 to effectively increase the strength of coupling the dampers 4 to the magnetic member 2 and the assembly-auxiliary frame 3 and prevent the separation of the dampers 4 from the magnetic member 2 and the assembly-auxiliary frame 3. The first fitting portions 45 are coupled to the second fitting portions 2133 by rugged structures respectively.

In addition to the aforesaid embodiments, an embodiment has technical features as follows: the assembly-auxiliary frame 3, the dampers 4, and the transverse short-side magnetic plates 213 of the main magnetic plate 21 are integrally formed by injection molding. Upon completion of the injection molding, the dampers 4 form a plurality of first fitting portions 45 which can enter the second fitting portions 2133 respectively to allow the first fitting portions 45 to be fitted to the assembly-auxiliary frame 3 and the second fitting portions 2133 of the transverse short-side magnetic plates 213. Thus, it is not necessary to apply an adhesive to between the magnetic member 2, the assembly-auxiliary frame 3, and the dampers 4 in order to finish mounting the dampers 4 in place to quickly and easily mount the dampers 4 in place, enhancing the production yield.

In addition to the aforesaid embodiments, an embodiment has technical features as follows: two short-side sides of the speaker base 11 each have an electrically conductive sheet 16; the electrically conductive sheets 16 each have a first electrode 161 and a second electrode 162; the first electrodes 161 are each disposed at the top of the speaker base 11; the second electrodes 162 are each disposed at the bottom of the speaker base 11; two short-side sides of the assembly-auxiliary frame 3 each have a first dent 34; the transverse short-side magnetic plates 213 each have a second dent 2132; the second electrodes 162 are disposed in the first dents 34 respectively, the first dents 34 are disposed at the second dents 2132 respectively; and the voice coil 13 is electrically connected to the first electrodes 161. When the vibration damping loudspeaker is coupled to an acoustic enclosure (not shown), external electronic signal lines (not shown) are electrically connected to the second electrodes 162 respectively to allow the voice coil 13 of the sound-generating unit 1 to receive external electronic signals such that the main magnetic plate 21 and the magnetic unit 22 of the magnetic member 2 coordinate with each other to provide more magnetic energy to allow the voice coil 13 to coordinate with the electromagnetic effect of the magnetic member 2 to drive the diaphragm 12 vibrating, increasing the sound volume of the vibration damping loudspeaker in operation. With the dampers 4 being positioned at four corners between the assembly-auxiliary frame 3 and the magnetic member 2 respectively, a magnetic gap 211 of the magnetic member 2 and the voice coil 13 of the sound-generating unit 1 align with each other accurately in the directions of X-axis, Y-axis and Z-axis when the assembly-auxiliary frame 3, the magnetic member 2 and the sound-generating unit 1 are mounted in place, enhancing the yield of the magnetic member 2 and the sound-generating unit 1 mounted in place.

Referring to FIG. 5, two short-side sides (test point 1 and test point 3) and two long-side sides (test point 2 and test point 4) of the vibration damping loudspeaker of the disclosure each have a vibration sensing component. Likewise, two short-side sides (test point 1 and test point 3) and two long-side sides (test point 2 and test point 4) of a conventional loudspeaker each have a vibration sensing component. As shown in FIG. 5, the test shows that the vibration damping loudspeaker of the disclosure surpasses the conventional loudspeaker in vibration damping.

Referring to FIG. 6 through FIG. 13, the second embodiment of the disclosure provides another vibration damping loudspeaker comprising a sound-generating unit 1, a magnetic member 2, an assembly-auxiliary frame 3 and a plurality of dampers 4. The sound-generating unit 1 comprises a speaker base 11, a diaphragm 12, a voice coil 13 and at least a spider 14. The speaker base 11 is cuboid (or cubic) and has a plurality of positioning units 111. The positioning units 111 are convex structures, slot structures or engaging structures. The diaphragm 12 is cuboid (or cubic) and is disposed at the top of the speaker base 11. The voice coil 13 is cuboid (or cubic) and is connected to the bottom of the diaphragm 12. The spider 14 is in the number of two and are symmetrically disposed between each of short-side sides 112 of the speaker base 11 and a corresponding one of short-side sides 131 of the voice coil 13 (alternatively, the spiders 14 are integrally disposed between the speaker base 11 and the voice coil 13). The spiders 14 are each integrally formed and each have a first connection side 141, a second connection side 142, at least a connection segment 143 and at least a ventilation unit 144. The connection segment 143 is U-shaped and is connected between the first connection side 141 and the second connection side 142. The ventilation unit 144 is a penetrating hole and is disposed between the first connection side 141, the second connection side 142 and the connection segment 143. The first connection side 141 is connected to the bottoms of short-side sides 112 of the speaker base 11. The second connection side 142 is connected to the bottoms of short-side sides 131 of the voice coil 13. The magnetic member 2 is cuboid (or cubic) and comprises a main magnetic plate 21 and a magnetic unit 22. The magnetic unit 22 comprises a magnet 221 and a magnetic plate 222 which are stacked up. The magnet 221 is disposed at the top of the main magnetic plate 21. The voice coil 13 is movably disposed in the magnetic gap 211 outside the magnetic unit 22. The assembly-auxiliary frame 3 is cuboid (or cubic) and has a plurality of aligning units 321. The aligning units 321 are complementary structures that complement the positioning units 111 respectively, and the complementary structures are slot structures, convex structures or engaging structures. The aligning units 321 are coupled to the positioning units 111 respectively to allow the assembly-auxiliary frame 3 to be mounted on the speaker base 11. The dampers 4 are in a number not restrictive of the disclosure and are symmetrically disposed between each of the long-side sides of the main magnetic plate 21 and a corresponding one of long-side sides 31 of the assembly-auxiliary frame 3 (Alternatively, the dampers 4 are symmetrically disposed between each of the two short-side sides of the main magnetic plate 21 and a corresponding one of two short-side sides 32 of the assembly-auxiliary frame 3.)

Thus, regarding the assembly process of the vibration damping loudspeaker of the disclosure, the aligning units 321 of the assembly-auxiliary frame 3 are coupled to the positioning units 111 of the speaker base 11 respectively to preclude deviations of the sound-generating unit 1 and the magnetic member 2 relative to each other to allow the sound-generating unit 1 and the magnetic member 2 to be quickly and easily mounted in place to enhance the production yield. An appropriate adhesive is coated onto an attachment surface of the assembly-auxiliary frame 3 (or the top surfaces of the dampers 4) to allow the assembly-auxiliary frame 3 to be fixed to the speaker base 11. Therefore, not only is the voice coil 13 precisely positioned in the magnetic gap 211 of the magnetic member 2, but it is also impossible for the magnetic member 2 to hit the voice coil 13 to damage the voice coil 13 during the assembly process. The vibration damping loudspeaker in operation can be coupled to an acoustic enclosure (not shown) such that the voice coil 13 of the sound-generating unit 1 receives external electronic signals; then, the main magnetic plate 21 and the magnetic unit 22 of the magnetic member 2 coordinate with each other to provide more magnetic energy to allow the voice coil 13 to coordinate with the electromagnetic effect of the magnetic member 2 to drive the diaphragm 12 vibrating, increasing the sound volume of the vibration damping loudspeaker in operation. The spiders 14 of the vibration damping loudspeaker of the disclosure each have a ventilation unit 144 and are flat as shown in FIG. 6 or of any other shape (for example, wavy shape) to allow the vibration damping loudspeaker of the disclosure to discharge a gas to the outside to increase the rated power (for example, 2W or above). When the vibration damping loudspeaker of the disclosure is subjected to a high power, the voice coil 13 and the diaphragm 12 undergo vibration characterized by a large axial displacement. The spiders 14 enable the voice coil 13 and the diaphragm 12 to undergo axial movement without deviations, preventing the voice coil 13 and the diaphragm 12 from colliding with the other components of the vibration damping loudspeaker of the disclosure to end up in distortion or damage.

When the vibration damping loudspeaker of the disclosure is operating, the assembly-auxiliary frame 3 and the dampers 4 together preclude direct contact between the speaker base 11 of the sound-generating unit 1 and the magnetic member 2, and the dampers 4 function as a buffer between the speaker base 11 and the magnetic member 2 to not only absorb (consume) the kinetic energy generated from the vibration of the speaker base 11 but also preclude the reverse transmission of the kinetic energy generated from the vibration of the magnetic member 2, so as to achieve vibration damping and vibration isolation during the operation of the vibration damping loudspeaker to spare users the discomfort they will otherwise experience for using electronic devices. With the dampers 4 functioning as a buffer between the speaker base 11 and the magnetic member 2, the magnetic member 2 and the speaker base 11 have similar vibration frequency but opposite phases, further enhancing vibration damping.

As shown in FIG. 6 through FIG. 13, in an embodiment, the spiders 14 of the vibration damping loudspeaker are each disposed between each of two short-side sides 112 of the speaker base 11 and a corresponding one of two short-side sides 131 of the voice coil 13 and are symmetrically arranged. The main magnetic plate 21 has two longitudinal long-side magnetic plates 212. The longitudinal long-side magnetic plates 212 are integrally formed with the main magnetic plate 21. The voice coil 13 is movably disposed in the magnetic gap 211 between each of the longitudinal long-side magnetic plates 212 and the magnetic unit 22. The dampers 4 are each disposed between each of the longitudinal long-side magnetic plates 212 of the main magnetic plate 21 and a corresponding one of the two long-side sides 31 of the assembly-auxiliary frame 3. The assembly-auxiliary frame 3 has two downward-concave short-side sides 32 so as to be connected between the long-side sides 31 of the assembly-auxiliary frame 3. The assembly-auxiliary frame 3 is integrally formed. Two ends of each of the downward-concave short-side sides 32 of the assembly-auxiliary frame 3 are connected to a corresponding one of the long-side sides 31 of the assembly-auxiliary frame 3 by an S-shaped connection segment, allowing the downward-concave short-side sides 32 and the main magnetic plate 21 to lie at the same horizontal position (as shown in FIG. 12) or substantially the same horizontal position. Therefore, notches are formed between the short-side sides 112 of the speaker base 11 and the downward-concave short-side sides 32 to provide sufficient space required for discharging a gas from the inside of the vibration damping loudspeaker when the vibration damping loudspeaker is subjected to a high power. The notches provide reserved space dedicated to the vibration of the spiders 14 to allow the spiders 14 to perform a damping function.

As shown in FIG. 6 and FIG. 7, an embodiment of the disclosure has technical features as follows: the dampers 4 of the vibration damping loudspeaker each have a first fitting unit 41 (for example, a fitting slot with a fitting cylinder) and a second fitting unit 42 (for example, a fitting slot with a fitting cylinder); the longitudinal long-side magnetic plates 212 of the main magnetic plate 21 each have at least a third fitting unit 2121 (for example, an L-shaped fitting plate with a fitting hole); the long-side sides 31 of the assembly-auxiliary frame 3 each have at least a fourth fitting unit 311 (for example, a transverse fitting plate with a fitting hole), with the first fitting unit 41 fitted to the third fitting unit 2121, and the second fitting unit 42 fitted to the fourth fitting unit 311. Therefore, according to the disclosure, the longitudinal long-side magnetic plates 212 of the main magnetic plate 21, the dampers 4, and the long-side sides 31 of the assembly-auxiliary frame 3 are fitted to each other by means of fitting.

As shown in FIG. 6 and FIG. 7, in an embodiment, the longitudinal long-side magnetic plates 212 of the main magnetic plate 21, the dampers 4, and the long-side sides 31 of the assembly-auxiliary frame 3 of the vibration damping loudspeaker are integrally formed by injection molding to further augment the strength of coupling together the longitudinal long-side magnetic plates 212 of the main magnetic plate 21, the dampers 4, and the long-side sides 31 of the assembly-auxiliary frame 3. For example, the dampers 4 are each coupled to between a corresponding one of the longitudinal long-side magnetic plates 212 of the main magnetic plate 21 and a corresponding one of the long-side sides 31 of the assembly-auxiliary frame 3 by injection molding. Therefore, it is not necessary to apply an adhesive to between the magnetic member 2, the assembly-auxiliary frame 3, and the dampers 4 in order to finish mounting the dampers 4 in place to quickly and easily mount the dampers 4 in place, enhancing the production yield.

Referring to FIG. 15 through FIG. 20, the third embodiment of the disclosure provides yet another vibration damping loudspeaker with distinguishing technical features described below. The spiders 14 are each disposed between one of the two short-side sides 112 of the speaker base 11 and a corresponding one of the two short-side sides 131 of the voice coil 13 and are symmetrically arranged. The main magnetic plate 21 has two longitudinal long-side magnetic plates 212 and two transverse short-side magnetic plates 213. The longitudinal long-side magnetic plates 212 and the transverse short-side magnetic plates 213 are integrally formed with the main magnetic plate 21. The voice coil 13 is movably disposed in the magnetic gap 211 between the longitudinal long-side magnetic plates 212 and the magnetic unit 22. The thickness of the transverse short-side magnetic plates 213 is less than the thickness of the main magnetic plate 21. The assembly-auxiliary frame 3 has two upward-convex short-side sides 33 so as to be connected between the two long-side sides 31 of the assembly-auxiliary frame 3. The assembly-auxiliary frame 3 is integrally formed. Two ends of each of the upward-convex short-side sides 33 of the assembly-auxiliary frame 3 are connected to a corresponding one of the long-side sides 31 of the assembly-auxiliary frame 3 by an S-shaped connection segment, allowing each of the dampers 4 to be disposed between a corresponding one of the transverse short-side magnetic plates 213 of the main magnetic plate 21 and a corresponding one of the upward-convex short-side sides 33 of the assembly-auxiliary frame 3. Therefore, notches are formed between the short-side sides 112 of the speaker base 11 and the upward-convex short-side sides 33 to provide sufficient space required for discharging a gas from the inside of the vibration damping loudspeaker when the vibration damping loudspeaker is subjected to a high power. The notches provide reserved space dedicated to the vibration of the spiders 14 to allow the spiders 14 to perform a damping function. The vibration damping loudspeaker of the disclosure incurs minimal processing cost because of the structural simplicity and integrity of the main magnetic plate 21 and the longitudinal long-side magnetic plates 212; for example, since there are no breaks in the main magnetic plate 21 and the longitudinal long-side magnetic plates 212, it is feasible to maintain magnetic permeation efficiency, increase the sound volume of the loudspeaker, reduce the distortion of the loudspeaker, allow the assembly-auxiliary frame 3 to dispense with any related structure thereof, and thus augment the mechanical strength of the assembly-auxiliary frame 3. Owing to the structural simplicity and integrity of the assembly-auxiliary frame 3, it is feasible for the long-side sides 31 of the assembly-auxiliary frame 3 and the long-side sides of the speaker base 11 to have more adhesive surfaces for augmenting the stability of the assembly-auxiliary frame 3 and the speaker base 11 mounted in place. The dampers 4 enclose the transverse short-side magnetic plates 213 of the main magnetic plate 21 to absorb (consume) the kinetic energy generated from the vibration of the main magnetic plate 21 and the assembly-auxiliary frame 3 in the horizontal and vertical directions.

As shown in FIG. 15 and FIG. 16, an embodiment of the disclosure has distinguishing technical features described below. The dampers 4 of the vibration damping loudspeaker each have a fifth fitting unit 43 (for example, U-shaped fitting slot) and a sixth fitting unit 44 (for example, U-shaped fitting convex). The transverse short-side magnetic plates 213 of the main magnetic plate 21 each have a seventh fitting unit 2131, and the seventh fitting unit 2131 is a fitting slot formed as a result of the difference in thickness between the transverse short-side magnetic plate 213 and the main magnetic plate 21. The upward-convex short-side sides 33 of the assembly-auxiliary frame 3 each have an eighth fitting unit 331 (for example, U-shaped fitting slot), with the fifth fitting unit 43 fitted to the seventh fitting unit 2131, and the sixth fitting unit 44 fitted to the eighth fitting unit 331. Therefore, the transverse short-side magnetic plates 213 of the main magnetic plate 21, the dampers 4, and the upward-convex short-side sides 33 of the assembly-auxiliary frame 3 are fitted to each other by means of fitting.

As shown in FIG. 15 and FIG. 16, in an embodiment of the disclosure, the vibration damping loudspeaker has distinguishing technical features described below. The transverse short-side magnetic plates 213 of the main magnetic plate 21, the dampers 4, and the upward-convex short-side sides 33 of the assembly-auxiliary frame 3 are integrally formed by injection molding to further augment the strength of coupling together the transverse short-side magnetic plates 213 of the main magnetic plate 21, the dampers 4, and the upward-convex short-side sides 33 of the assembly-auxiliary frame 3. For example, the dampers 4 are coupled to between the transverse short-side magnetic plates 213 of the main magnetic plate 21 and the upward-convex short-side sides 33 of the assembly-auxiliary frame 3 by injection molding. Therefore, it is not necessary to apply an adhesive to between the magnetic member 2, the dampers 4, and the assembly-auxiliary frame 3 in order to finish mounting the dampers 4 in place to quickly and easily mount the dampers 4 in place, enhancing the production yield.

As shown in FIG. 15 through FIG. 20, in an embodiment of the disclosure, the vibration damping loudspeaker has distinguishing technical features described below. The dampers 4 are made of silicone, rubber or foam and mounted in place by any appropriate means, including injection molding. For example, the dampers 4 are formed from film made of foam or rubber and then directly adhered to adhesion positions between the assembly-auxiliary frame 3 and the main magnetic plate 21. Alternatively, soft plastic elements are injected onto regions defined at the adhesion positions between the assembly-auxiliary frame 3 and the main magnetic plate 21, allowing the assembly-auxiliary frame 3 and the main magnetic plate 21 to be coupled together. Since the assembly-auxiliary frame 3 need not have any reserved structure required for being coupled to the dampers 4 by injection molding, the assembly-auxiliary frame 3 exhibits structural integrity and high mechanical strength conducive to suppression of vibration of the vibration damping loudspeaker of the disclosure. The assembly-auxiliary frame 3 is made of plastic or metal. For instance, the assembly-auxiliary frame 3 is made of stainless steel or cold rolled steel sheet to augment the mechanical strength of the assembly-auxiliary frame 3. The augmented mechanical strength of the assembly-auxiliary frame 3 is conducive to both the deformation resistance and the vibration suppression capability of the vibration damping loudspeaker of the disclosure.

In the second embodiment (or third embodiment) of the disclosure, the vibration damping loudspeaker has distinguishing technical features described below. The dampers 4 are made of silicone, rubber or foam. When made of silicone, the dampers 4 have hardness of 40 to 60 degrees, preferably 60 degrees. The assembly-auxiliary frame 3 and the speaker base 11 are made of the same material or different materials. For example, the speaker base 11 is made of plastic, and the assembly-auxiliary frame 3 is made of metal. Preferably, the rigidity of the assembly-auxiliary frame 3 is greater than the rigidity of the speaker base 11, and thus the assembly-auxiliary frame 3 surpasses the speaker base 11 in mechanical strength.

As shown in FIG. 14, in the second embodiment (or third embodiment) of the disclosure, the vibration damping loudspeaker has distinguishing technical features described below. A plurality of soft plastic elements 5 symmetrically arranged are disposed between the two long-side sides 31 of the assembly-auxiliary frame 3 and the two longitudinal long-side magnetic plates 212 of the main magnetic plate 21. Therefore, the vibration damping loudspeaker of the disclosure is advantageous in that the dampers 4 coordinate with the soft plastic elements 5 to enhance vibration damping. The soft plastic elements 5 are made of UV-cured plastic. Owing to the low adhesion strength UV-cured plastic, the soft plastic elements 5 still exhibit hardness to a certain extent even after being cured. Therefore, UV-cured plastic is an appropriate vibration damping material.

While the present disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the present disclosure set forth in the claims.
