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

A kind of method that reduces the cell-phone receiver inefficacy

Technical field

The present invention relates to a kind of method that cell-phone receiver lost efficacy that reduces.

Background technology

At present, the receiver assembly structure of mobile phone is as shown in Figure 1 mostly, and PCB 3 is arranged in the casing 1 with receiver 4, for receiver 4 is provided with phonate hole 2 and Air Filter 6, has used cushion 5 to assemble Air Filter 6.From the operating position of present mobile phone, the environment that the consumer uses varies, and is complicated various; A large amount of iron filings dust is particularly arranged in the operational environment of iron and steel, mechanical processing industry; Because moving coil receiver itself is magnetic device, be easy to adsorb the dust such as iron filings that are present in around the mobile phone, when iron filings are sucked into through phonate hole; Fall on the vibrating diaphragm of receiver, will produce noise during receiver work.After mobile phone used a period of time simultaneously, everybody can find that foreign material such as some dusts, fiber are deposited on the Air Filter at place, receiver hole, and is difficult to clean out.Accumulate over a long period, when particularly hot weather was made a phone call, sweat flow in the receiver hole again, blocked with the dust and other impurities mesh that will prevent dust, and caused sound little, did not hear the other side's sound when making a phone call.Solve above two kinds of inefficacies and mainly improve from the phonate hole structure of receiver, but two kinds of requirements are again conflicting: phonate hole amplifies, and be not easy to block, but iron filings gets into easily; Air Filter is too close, and iron filings are not easy to get into, but block easily, also will satisfy the requirement of receiver acoustic construction simultaneously.Can finely prevent that through this solution iron filings from entering into receiver, prevent again that simultaneously dust and other impurities from blocking the receiver hole, also satisfy the requirement of receiver acoustic construction simultaneously, lose efficacy thereby reduce receiver to a great extent.

Summary of the invention

The objective of the invention is the above-mentioned defective to prior art, provide a kind of iron filings that prevent to enter into receiver, prevent that simultaneously dust and other impurities from blocking the receiver hole, thereby reduce the method that cell-phone receiver lost efficacy.

A kind of method that reduces the cell-phone receiver inefficacy provided by the invention is that cell-phone receiver is provided with the little double-deck phonate hole of outer imperial palace and close double-deck Air Filter in outer the dredging is set.

Preferably make outer Air Filter all unsettled up and down.

Preferably, outer Air Filter is arranged on the inner or end of outer phonate hole, the internal layer Air Filter is arranged on the inner or end of internal layer phonate hole.More preferably, said internal layer Air Filter is arranged on the end that the internal layer phonate hole is close to receiver, said internal layer Air Filter is pressed in through cushion on the wall body of said internal layer phonate hole, said cushion is between said receiver and said internal layer Air Filter.

Can the periphery of outer Air Filter be arranged in the wall body of outer phonate hole.

Can double-deck phonate hole all be set to cylinder hole.

Beneficial effect following points of the present invention: (1) can prevent that receiver from advancing iron filings, improves the useful life of receiver; (2) can prevent that receiver is plugged, reduce the inefficacy of receiver; (3) can satisfy the requirement of cell-phone receiver acoustic construction.

Description of drawings

Fig. 1 is the receiver structure installation diagram of prior art;

Fig. 2 is the receiver structure installation diagram that utilizes the present invention to obtain.

Among the figure: 1-casing, 101-internal layer casing, the outer casing of 102-, 2-phonate hole, the outer phonate hole of 201-, 202-Air Filter avoiding hollow groove, 203-internal layer phonate hole, 3-PCB, 4-receiver, 5-cushion, 6-Air Filter, 601-internal layer Air Filter, the outer Air Filter of 602-.

Embodiment

The present invention invents and adopts the little double-deck phonate hole of outer imperial palace; Close double-deck Air Filter in outer the dredging; Increase the speak structure of area of outer Air Filter.Both prevented that iron filings from entering into receiver, prevented again simultaneously that dust and other impurities from blocking the receiver hole, can satisfy the requirement of receiver acoustic construction again, and reduced receiver to a great extent and lost efficacy.

The double-deck phonate hole that outer imperial palace is little: outer phonate hole area is big, is not easy to be blocked by foreign material; Internal layer phonate hole area is little, and then iron filings also are not easy to get into.

Close double-deck Air Filter structure in outer the dredging: outer Air Filter is more sparse, is not easy to be blocked by foreign material; The internal layer Air Filter is fine and closely woven, even then iron filings have passed ground floor, can not pass second layer Air Filter.

Increase the speak structure of area of outer Air Filter: outer Air Filter is all unsettled up and down, and the area of speaking is bigger, even the Air Filter part is plugged, does not also influence the size of sound.

Illustrate the concrete structure that utilizes the present invention to invent to obtain below in conjunction with accompanying drawing, so that understand the present invention better.As shown in Figure 1; The PCB 3 and the receiver 4 of this mobile phone are arranged in the casing; For receiver 4 is provided with the little double-deck phonate hole of outer imperial palace (the outer phonate hole 201 and internal layer phonate hole 203 that are made up of outer casing 102 and internal layer casing 101 respectively); And be provided with double-deck Air Filter close in outer the dredging (internal layer Air Filter 601 and outer Air Filter 602); The periphery of outer Air Filter 602 is arranged in the wall body of outer phonate hole 201, outer Air Filter about in the of 602 (being the wire side both sides) all unsettled, form Air Filter avoiding hollow groove 202.Internal layer Air Filter 601 is arranged on an end of internal layer phonate hole 203 contiguous receivers 4, and internal layer Air Filter 601 is pressed in through cushion 5 on the wall body of internal layer phonate hole 203, and cushion 5 is between receiver 4 and internal layer Air Filter 601.
