Problems solved by technology

[0003] 1. Electret mics need welding wires, MEMS mics need fpc patches, and after assembly, they need to be sealed through the side of the speaker. Production and assembly are difficult, and the defect rate is high.
Noise canceling performance will be affected after reliability tests such as drops
[0004] 2. Both MICs need to be soldered or patched, plus sealing, which is costly;
[0006] 4. The problem of low yield due to assembly;

Abstract

The invention discloses a horn module device with an active noise reduction function, which comprises a module base and a horn, an adaptive screen cloth is arranged below the module base, an Fpc device is arranged above the module base, the Fpc device comprises an Fpc, and a touch IC and a silicon Mic are arranged on the Fpc. By means of the technical scheme, the active noise reduction earphone has the advantages of being simple and reliable in structure, long in service life, low in manufacturing cost, simple in production and assembly process, capable of saving PCB design space, especially capable of controlling consistency of active noise reduction type earphones, high in yield and the like.

Description

technical field [0001] The invention relates to the field of noise reduction earphones, in particular to a speaker module device with active noise reduction. Background technique [0002] We currently have many hybrid or single-feedback active noise-canceling headphones on the market. The design principle is to place a mic in the front cavity of the speaker to pick up the noise, but this method brings challenges to mic placement, production assembly and sealing, and the reliability is very high. Difficult to achieve. The speaker module device in the prior art mainly has the following disadvantages: [0003] 1. Electret mics need welding wires, MEMS mics need fpc patches, and after assembly, they need to be sealed through the side of the speaker. Production and assembly are difficult, and the defect rate is high. Noise canceling performance will be affected after reliability tests such as dropping. [0004] 2. Both MICs need to be soldered or patched, plus sealing, which i...
