Problems solved by technology

To solve the above two failures, the main improvement is to improve the sound hole structure of the receiver, but the two requirements are contradictory: the sound hole is enlarged and is not easy to block, but iron filings are easy to enter; the dust-proof net is too dense, and the iron Chips are not easy to enter, but easy to block, and at the same time meet the requirements of the acoustic structure of the receiver

Embodiment Construction

[0013] The present invention adopts double-layer sound holes with large outside and small inside; double-layer dust-proof nets with sparse outside and dense inside; and a structure that increases the sound-emitting area of ​​the outer dust-proof net. It not only prevents iron filings from entering the receiver, but also prevents dust and other debris from blocking the receiver hole, and can meet the requirements of the receiver's acoustic structure, greatly reducing receiver failure.

[0014] Double-layer sound holes with large outside and small inside: the outer layer has a large sound hole area, which is not easy to be blocked by debris; the inner layer sound hole area is small, and iron filings are not easy to enter.

[0015] Double-layer dust-proof net structure with sparse outside and dense inside: the outer dust-proof net is relatively sparse and is not easily blocked by debris; the inner dust-proof net is fine and dense, so even if the iron filings pass through the first...

Abstract

The invention relates to a method for reducing failure of a receiver of a mobile phone which is characterized by arranging a double-layer noise making hole with a big exterior and a small interior, and a double-layer dust screen on the receiver of the mobile phone. The method has the advantages of (1) preventing scrap irons entering the receiver and improving the service life of the receiver; (2) preventing the receiver from being blocked and reducing the failure of the receiver; and (3) meeting the requirement of the acoustic structure of the receiver of the mobile phone.

Description

technical field [0001] The invention relates to a method for reducing failure of a mobile phone receiver. Background technique [0002] At present, the assembly structures of mobile phone receivers are mostly as follows: figure 1 As shown, the PCB 3 and the receiver 4 are arranged in the casing 1, and the receiver 4 is provided with a sound outlet 2 and a dust-proof net 6, and the cushion 5 is used to assemble the dust-proof net 6. Judging from the current usage of mobile phones, the environments used by consumers are varied and complex. Especially in the working environment of the steel and machining industries, there are a lot of iron filings and dust. Since the dynamic receiver itself is a magnetic device, it is very difficult to It is easy to absorb dust such as iron filings around the mobile phone. When the iron filings are sucked in through the sound hole and fall on the diaphragm of the receiver, noise will be generated when the receiver is working. At the same time...
