Description

Technical Field

[0001] The utility model relates to the technical field of speaker cones, in particular to a dustproof speaker cone. Background Art

[0002] The cone is the main sound-generating part of the speaker. When the speaker is working, the voice coil will generate strong vibrations in the magnetic field after receiving the audio signal. Since the voice coil is fixed on the cone, the vibration of the voice coil will also drive the vibration of the cone, and the vibration of the cone further forces the air to vibrate, thereby making a sound. Therefore, the quality of the sound of the cone determines the quality of the speaker. Existing speakers will install dust caps to prevent dust from entering, but the dust caps are fixed to the cones with glue. The glue will age during long-term use and will gradually lose its adhesiveness, causing the dust cap to fall off. In addition, the vibration of the voice coil will further accelerate the speed at which the dust cap falls off, reducing the stability of the position of the dust cap, affecting normal use, and the dustproof effect is poor.

[0020] The utility model is described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 to Figure 2 As shown, the utility model is a dustproof speaker cone, comprising a body 1, a suspension edge 2 arranged on the body 1 and a dustproof component 3 arranged on the suspension edge 2, the dustproof component 3 is arranged around the circumference of the suspension edge 2, the suspension edge 2 comprises an inner ring member 21, an outer ring member 22 arranged concentrically with the inner ring member 21 and an annular groove 23 arranged between the inner ring member 21 and the outer ring member 22, the annular groove 23 is recessed from the connection between the inner ring member 21 and the outer ring member 22, the inner groove wall of the annular groove 23 is convexly provided with a clamping strip 24, and the dustproof component 3 is provided with a clamping groove 31 for accommodating the clamping strip 24.

[0022] When in use, it is only necessary to press the dustproof component 3 downward into the hanging edge 2, and the dustproof component 3 is engaged with the engaging strip 24 through the engaging groove 31, and the annular groove 23 is used to effectively clamp and fix the dustproof component 3, which helps the dustproof component 3 to be arranged around the circumference of the hanging edge 2, thereby preventing dust from entering the body 1, effectively blocking dust and impurities on the dustproof component 3, and ensuring the normal use of the sound basin. When it is necessary to disassemble and replace the dustproof component 3, it is only necessary to pull the outer ring 22 outward to drive the engaging strip 24 of the annular groove 23 to disengage from the engaging groove 31, so as to facilitate the removal of the dustproof component 3 from the hanging edge 2, and facilitate disassembly, replacement and use, and a long service life. The utility model has a compact structure and a reasonable design, the position stability of the dustproof component 3 is good, the installation and disassembly are convenient, and the dustproof effect is improved.

[0023] The dustproof assembly 3 of this embodiment includes a dustproof net 32 ​​and an annular rib 33 provided on the dustproof net 32. The clamping groove 31 is formed by being recessed from the side wall of the annular rib 33. The annular rib 33 protrudes into the annular groove 23 so that the clamping groove 31 abuts against the clamping strip 24 to prevent the dustproof net 32 ​​from being separated from the hanging edge 2. Specifically, the dustproof net 32 ​​protrudes into the annular groove 23 through the annular rib 33 so that the clamping groove 31 abuts against the clamping strip 24 to prevent the dustproof net 32 ​​from being separated from the hanging edge 2. The main body of the dustproof net 32 ​​is exposed to the external environment, which can prevent dust, particles, sundries, etc. in the air from entering and adhering to the body 1 and affecting the normal performance of the sound basin, thereby playing a role in dustproof protection.

[0024] The annular groove 23 of this embodiment has a U-shaped structure, and the annular groove 23 is provided with a positioning column 25, which is formed by protruding from the bottom wall of the annular groove 23, and the annular rib 33 is provided with a positioning groove 34, which is formed by recessing from the bottom wall of the annular rib 33, and the positioning column 25 is accommodated in the positioning groove 34. Specifically, when the dust screen 32 protrudes into the annular groove 23 through the annular rib 33, the annular groove 23 with a U-shaped structure is tightly fitted to the outer wall of the annular rib 33, with a large contact area, and the positioning column 25 protrudes into the positioning groove 34, which better fixes the position of the annular rib 33 in the annular groove 23, thereby improving the connection firmness between the annular rib 33 and the annular groove 23.

[0025] In this embodiment, the inner ring 21, the annular groove 23, and the outer ring 22 are integrally formed. The inner ring 21 is tilted downward toward the outer wall of the carcass 1. An adhesive coating 26 is provided on the outer side of the inner ring 21. The inner ring 21 is connected to the carcass 1 through the adhesive coating 26. Specifically, the inner ring 21, the annular groove 23, and the outer ring 22 are integrally formed and combined to form the suspension edge 2. The integrated overall structure is firm and reliable, and there is no need to perform too many assembly production steps, which makes the production process simple. The inner ring 21 is tilted downward toward the outer wall of the carcass 1 to increase the contact area between the inner ring 21 and the carcass 1. The inner ring 21 is connected to the carcass 1 through the adhesive coating 26, and then the inner ring 21 is fixed on the carcass 1 using the existing hot pressing process, and the structure is compact.

[0026] The outer wall of the carcass 1 of this embodiment is provided with an antistatic coating 4. Specifically, the antistatic coating 4 effectively prevents dust and debris from being adsorbed on the outer surface of the carcass 1 due to static electricity, further improving the dustproof effect and having strong practicality.

[0027] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
