Description

头带式ANC降噪耳机外后腔密封结构Headband-type ANC noise-cancelling earphones with a sealed structure in the outer and rear chambers 技术领域technical field

本实用新型涉及降噪耳机技术领域,具体而言,涉及头带式ANC降噪耳机外后腔密封结构。The utility model relates to the technical field of noise-reduction earphones, in particular to a sealing structure of the outer and rear cavity of a headband-type ANC noise-reduction earphone.

背景技术Background technique

当前市场为了满足消费者追求真实、逼真,更清晰的音质体验,通过在耳机增加ANC降噪功能来达到这种声学效果,但是ANC对耳壳外后腔的密封性要求很高,同时由于耳壳侧面有多个开关,插座及LED等等孔槽间隙,在结构设计上要做到良好的密封性及左右耳机一致性有非常大的难度,结构上过多的拆件及逐点用胶水密封,这样会使生产的成本提升及增加产品的生产难度,而导致产品在市场上失去竞争优势,市场上带有ANC的头带耳机为了达到良好的降噪效果,针对耳壳上的开关,按键,USB插座等等的装配缺口及缝隙,都要做隔离密封,大部分在结构设计上采用了分割隔离,单点密封,成本上没有优势,装配工艺也比较繁琐复杂,因此我们提出了头带式ANC降噪耳机外后腔密封结构。In the current market, in order to meet consumers’ pursuit of real, realistic, and clearer sound quality experience, this acoustic effect is achieved by adding ANC noise reduction function to the earphones. There are multiple switches, sockets and LED slots on the side of the shell. It is very difficult to achieve a good seal in the structural design and the consistency of the left and right earphones. There are too many disassembled parts and glue point by point in the structure. Sealing, this will increase the cost of production and increase the difficulty of product production, which will cause the product to lose its competitive advantage in the market. In order to achieve a good noise reduction effect, the headband earphones with ANC on the market aim at the switch on the ear shell. The assembly gaps and gaps of buttons, USB sockets, etc. must be isolated and sealed. Most of them adopt split isolation and single-point sealing in structural design. There is no advantage in cost, and the assembly process is also cumbersome and complicated. Belt-type ANC noise-canceling earphones have a sealed structure in the outer and rear chambers.

The screw holes are aligned with the two mounting columns, and the circuit board 6 is fixed on the upper ends of the two mounting columns by screws, so that the installation of the circuit board 6 is completed. The cavity tuning net 5 can effectively filter external noise through the back cavity tuning net 5, and the microphone set 11 installed inside the fixed groove 15 can make the microphone 10 be installed on the inner surface of the microphone set 11, and the microphone set 11 can be installed on the lower surface. The microphone tuning network 12 is used to filter out external noise when people use the microphone 10. After the microphone tuning network 12, the microphone cover 11 and the microphone 10 are all installed in the fixing groove 15, the microphone upper cover 9 is installed on the fixed groove. The upper end of the slot 15 is then welded and fixed to the microphone upper cover 9 and the fixing slot 15 by ultrasonic welding, and then the screw holes provided on the outer rear cavity cover 4 are aligned with the screw holes provided on the earphone shell 13, and the outer rear cover 9 is fixed by using screws. The cavity cover 4 is fixed to the earphone shell 13, and then the gap between the outer rear cavity cover 4 and the earphone shell 13 is sealed by glue, and then the speaker 2 is installed on the lower surface of the speaker front cover 1, and the rear cavity cover is fixed by screws 8. 3. Fix it on the lower surface of the speaker front cover 1, make the rear chamber cover 3 cover the speaker 2 on the speaker front cover 1, then align the speaker front cover 1 with the earphone shell 13, and fix it with screws to complete the installation.
