Abstract
The utility model relates to a sound production device of an electronic product, in particular to a sound production device of an anti-magnetic structure which is applied to mobile phones. The sound production device comprises a sound producer and a frame loading the sound producer, a sound transmission hole is arranged at a position of the frame opposite to a sound production direction of the sound producer, the sound transmission hole is covered with a metal cover made of magnetic conductive materials, and the metal cover is provided with a through hole facing towards the sound transmission hole. The sound production device with the structure can stop magnetic lines of force of magnetic steel of the sound producer when the electronic product touches a metal object so as to greatly reduce magnetism received by an outer casing of a mobile phone. When a mobile phone user utilizes the mobile phone, magnetic conductive metal objects such as iron, nickel and the like or metal particles are difficult to be adsorbed by the mobile phone even in a short distance so that possibility of the metal objects or metal particles entering the sound producer is reduced, thereby guaranteeing normal operation of the sound producer.
Description
[technical field]
The utility model relates to the sound-producing device of electronic product, specifically refers to a kind of sound-producing device that is applied to anti-magnetic structure on the mobile phone.
[background technology]
Development along with wireless telecommunications, Global Mobile Phone Users is more and more, the user not only is satisfied with conversation to the requirement of mobile phone, and want high-quality communication effect can be provided, especially at present the development of mobile multimedia technology, the speech quality of mobile phone becomes more important, and the microphone of mobile phone is as the voice pick device of mobile phone, and its design quality directly influences speech quality.
Usually sound-producing device is to be fixedly mounted on the plastic frame in the mobile phone, also is mounted with other electronic components on this plastic frame, plastic frame is installed on the mobile phone outer casing again.People are in using the mobile phone process, consciously or unconsciously mobile phone can be pressed close to the metal of some magnetic conductions, yet there is the magnet of high magnetic will attract these metal objects in the sound-producing device, metal object is sucked into can destroy inner sound membrane structure undoubtedly in the sound-producing device, to influence the reliability of mobile phone, this be people do not wish to see.
[utility model content]
The purpose of this utility model is to solve the antimagnetic problem of sound-producing device in the existing electronic product, and proposes a kind of sound-producing device of anti-magnetic structure.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of sound-producing device of anti-magnetic structure, the framework that comprises acoustical generator, loading acoustical generator, the position of relative acoustical generator voice directions offers sound penetrating hole on the described framework, be covered with the crown cap that magnetic conductive material is made on the wherein said sound penetrating hole, offer through hole on the described crown cap over against sound penetrating hole.
Described framework is provided with the holddown groove that prevents that crown cap is subjected to displacement.
Described crown cap is placed between acoustical generator and the framework.
Described crown cap is placed on the another side of relative acoustical generator on the framework.
The sound-producing device of a kind of anti-magnetic structure of the utility model, the framework that comprises acoustical generator, loading acoustical generator, the position of relative acoustical generator voice directions offers sound penetrating hole on the described framework, be covered with the crown cap that magnetic conductive material is made on the wherein said sound penetrating hole, offer through hole on the described crown cap over against sound penetrating hole.This structure makes can stop the magnetic line of force of acoustical generator magnet steel when electronic product is run into metal object; the magnetic that makes phone housing partly receive reduces greatly; the cellphone subscriber in use; the metal object of magnetic conductions such as iron nickel or metallic particles can adsorb in that closer distance is also difficult; enter the probability of acoustical generator inside with minimizing, thereby protect acoustical generator energy operate as normal.
[description of drawings]
Fig. 1 is the utility model blast structural representation.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is elaborated.
Join shown in Figure 1ly, be the sound-producing device blast structural representation of the anti-magnetic structure of the utility model, it comprises shell 10, loads plastic frame 20, acoustical generator 30 and the crown cap 40 of electronic component.Described acoustical generator 30 is a micro loudspeaker unit, also can be the loud speaker module after the encapsulation, and it is installed on the framework 20, and framework 20 is fixed on the shell 10, and shell 10 is provided with phonate hole 11.The position of relative acoustical generator 30 voice directions offers sound penetrating hole 21 on the described framework 20, is covered with the crown cap 40 that magnetic conductive material is made on the described sound penetrating hole 21, offers the through hole 41 over against sound penetrating hole 21 on the described crown cap 40.
In the present embodiment, described framework 20 is provided with the holddown groove 22 that prevents that crown cap 40 is subjected to displacement, and holddown groove 22 also can be made as the projection that is embedded crown cap 40 certainly, does not exceed with above-mentioned execution mode.Described crown cap 40 is placed between acoustical generator 30 and the framework 20 in addition, and perhaps crown cap 40 is placed on the another side of relative acoustical generator 30 on the framework 20, promptly between shell 10 and the framework 20.This structure makes can stop the magnetic line of force of acoustical generator magnet steel when electronic product is run into metal object; the magnetic that makes phone housing 10 parts receive reduces greatly; the cellphone subscriber in use; the metal object of magnetic conductions such as iron nickel or metallic particles can adsorb in that closer distance is also difficult; enter the probability of acoustical generator 30 inside with minimizing, thereby protect acoustical generator 30 energy operate as normal.
The above only is a better embodiment of the present utility model; protection range of the present utility model does not exceed with above-mentioned execution mode; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection range of putting down in writing in claims.
