Description

Technical Field

[0001] The present invention relates to a damping structure for a speaker with glue, belonging to the technical field of speaker products. Background Art

[0002] In order to reduce the influence of the speaker when it emits sound on the terminal product (such as a laptop computer), generally, the U-shaped iron in the speaker vibrates to reduce the influence on the terminal product. A gap needs to be reserved between the U-shaped iron and the chassis to provide space for vibration. However, in this way, the ventilation volume during the operation of the speaker unit will increase, and too much air flow out during the operation of the speaker unit, which will reduce the power tolerance and voltage tolerance performance of the speaker. Summary of the Invention

[0003] The main technical problem to be solved by the present invention is to provide a damping structure for a speaker with glue, which can reduce the air flow out during the operation of the speaker unit, and the ventilation volume during the operation of the speaker unit will not increase, nor will it affect the vibration during the operation of the speaker unit.

[0004] To solve the above technical problem, a technical solution adopted by the present invention is: to provide a damping structure for a speaker with glue, including a chassis, a U-shaped iron is arranged on the chassis, a magnet is arranged on the U-shaped iron, a washer is arranged on the magnet, a voice coil is arranged outside the magnet and the washer, the voice coil is located inside the chassis, a diaphragm is arranged on the top of the chassis, there is a gap between the chassis and the U-shaped iron, and the gap is filled with damping glue.

[0005] Preferably, the damping glue is soft glue.

[0006] Preferably, metal shrapnel is respectively arranged at both ends of the U-shaped iron.

[0007] The beneficial effect of the present invention is: the damping structure for a speaker with glue of the present invention fills soft damping glue in the gap between the U-shaped iron and the chassis to block the gap, which can reduce the air flow out during the operation of the speaker unit, and the ventilation volume during the operation of the speaker unit will not increase. At the same time, the soft damping glue has elasticity and will not affect the vibration during the operation of the speaker unit, nor will it reduce the power tolerance and voltage tolerance performance of the speaker. Description of the Drawings

[0008] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained according to these drawings, where:

[0009] Figure 1 and Figure 2 are the structural cross-sectional views of the damping structure for a speaker with glue of the present invention in different sectional directions;

[0010] Figure 3 It is the bottom view of the horn glue-adding shock-absorbing structure of the present invention;

[0011] Figure 4 It is the exploded view of the structure of the horn glue-adding shock-absorbing structure of the present invention. Specific embodiments

[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0013] Embodiments of the present invention:

[0014] Please refer to Figures 1 to 4 , the horn glue-adding shock-absorbing structure of the present invention includes a chassis 1, a U-shaped iron 7 is arranged on the chassis 1, a magnet 6 is arranged on the U-shaped iron 7, a washer 5 is arranged on the magnet 6, a voice coil 3 is arranged outside the magnet 6 and the washer 5, the voice coil 3 is located inside the chassis 1, a diaphragm 2 is arranged on the top of the chassis 1, there is a gap 8 between the chassis 1 and the U-shaped iron 7, and the gap 8 is filled with damping glue 9, and the damping glue 9 is a soft glue. The damping glue 9 blocks the gap 8, which can reduce the air flow out when the horn unit works, and the ventilation volume when the horn unit works will not increase. At the same time, the soft damping glue 9 has elasticity and will not affect the vibration of the U-shaped iron during work, nor will it reduce the power resistance and voltage resistance performance of the horn. The damping glue 9 can also disperse the magnetic circuit resonance, thereby increasing the shock-absorbing effect of the product.

[0015] Preferably, metal shrapnel 4 is arranged at both ends of the U-shaped iron 7, and the metal shrapnel 4 can vibrate when the horn unit works.

[0016] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
