Abstract
The utility model relates to the field of mobile phones, in particular relates to a mobile phone with strong sound effects. A pure iron protective cover is arranged on a loudspeaker, the magnetic flux of the loudspeaker can be reduced; a nickel annular magnetic conductive sheet is arranged inside a mobile phone shell body on the periphery of a sound outlet annular hole, and the magnetic lines of force of the loudspeaker are changed by utilizing the magnetic force of the nickel annular magnetic conductive sheet, thereby reducing the magnetic flux of the loudspeaker and preventing scrap iron from being attached to the surface of the loudspeaker. An annular curved-surface sound cavity body corresponds to a sound outlet center hole and the sound outlet annular hole which is formed in the mobile phone shell body in sequence from inside to outside, the center of the curved surface corresponds to the position of the sound outlet center hole, acoustic waves of the loudspeaker are reflected back through the curved surface of the annular curved-surface sound cavity body and then sent out through the sound outlet center hole and the sound outlet annular hole in a centralized manner, and are led out through included angle gaps formed by the desktop or other surfaces and a first arc projection and a second arc projection with height difference, thereby avoiding the acoustic shock, overcoming the problem that the traditional mobile phone has poor sound quality, and improving the overall sound quality of the loudspeaker.
Description
Technical field

along with the develop rapidly of electronic technology, mobile phone has become the requisite articles for daily use of people.For current mobile phone, except having traditional communication function, also have other many additional functions, particularly smart mobile phone concurrently, on its mobile phone, additional function is whether powerful, is determining to a great extent whether mobile phone has stronger attraction to user.After the leisure of work, study, people can emit music by mobile phone, and the mood of oneself is loosened.Yet current mobile phone, is subject to size restrictions, can only adopt loud speaker small-bore, muting sensitivity, acoustical quality is poor.
Summary of the invention
for overcoming above-mentioned defect, the purpose of this utility model is to provide a kind of strong acoustic mobile phone of having of mobile phone acoustical quality that improves.
the purpose of this utility model is achieved through the following technical solutions:
a kind of strong acoustic mobile phone that has of the present utility model, comprising: mobile phone body, in described mobile phone body, be provided with handset shell, pcb board, be arranged on the loud speaker on pcb board, on described handset shell, be provided with handset shell one-body molded, the circle ring surface sound cavity of circulating loudspeaker, between described circle ring surface sound cavity and pcb board, be provided with annulus sealing foam, described pcb board, annulus sealing foam, circle ring surface sound cavity and handset shell form sound chamber jointly, on described loud speaker, be provided with pure iron protective cover, on described handset shell, corresponding loudspeaker position place offers out sound centre bore from inside to outside successively, go out sound looping pit, describedly go out sound centre bore and go out on the handset shell between sound looping pit, to be provided with the first circular arc projection, on the described handset shell that goes out sound looping pit periphery, be provided with the second circular arc projection, the described handset shell inside that goes out sound looping pit periphery is provided with nickel matter annulus magnetic conduction sheet, describedly go out in sound looping pit to be also provided with equally distributed four auxiliary intercell connectors, the center of surface correspondence of described circle ring surface sound cavity goes out the position of sound centre bore, and the height of described the first circular arc projection is greater than the height of described the second circular arc projection.
further, described handset shell is cell phone rear cover.
the utility model provides a kind ofly has a strong acoustic mobile phone, and pure iron protective cover is set on loud speaker, can reduce the magnetic flux of loud speaker.In the handset shell inside that goes out sound looping pit periphery, be provided with nickel matter annulus magnetic conduction sheet, utilize the magnetic force of nickel matter annulus magnetic conduction sheet to change the magnetic line of force of loud speaker, thereby reduce the magnetic flux of loud speaker, and prevent that iron adsorption is on the surface of loud speaker simultaneously.One-body molded with handset shell, the circle ring surface sound cavity of circulating loudspeaker, that on corresponding handset shell, offers successively from inside to outside goes out sound centre bore, go out sound looping pit, the center of surface correspondence of circle ring surface sound cavity goes out the position of sound centre bore, the sound wave of loud speaker returns to concentrate from going out sound centre bore via the camber reflection of circle ring surface sound cavity, going out sound looping pit sends, and by there being the first circular arc projection of difference in height, the second circular arc projection derives with the angle gap that desktop or other surfaces produce, avoided sound wave shock, overcome the not good problem of conventional mobile phone tonequality, improved on the whole the acoustical quality of loud speaker.
Accompanying drawing explanation
for ease of explanation, the utility model is described in detail by following preferred embodiment and accompanying drawing.
to be that the utility model is a kind of have a strong acoustic handset structure schematic diagram to Fig. 1;
fig. 2 is a kind of partial schematic diagram with handset shell in strong acoustic mobile phone of the utility model.
Embodiment
in order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
please refer to Fig. 1-2, a kind of strong acoustic mobile phone that has of the present utility model, comprising: mobile phone body; In this mobile phone body, be provided with handset shell 1, pcb board 2, be arranged on the loud speaker 3 on pcb board 2, this handset shell 1 is preferably cell phone rear cover.On this handset shell 1, be provided with circle ring surface sound cavity 4 one-body molded with handset shell 1, circulating loudspeaker 3, between this circle ring surface sound cavity 4 and pcb board 2, be provided with annulus sealing foam 7, the common sound chamber 5 that forms of this pcb board 2, annulus sealing foam 7, circle ring surface sound cavity 4 and handset shell 1, this annulus sealing foam 7 can guarantee the isolation completely of sound chamber 5 and interior of mobile phone, reduces interior of mobile phone part the signal of loud speaker 3 is disturbed.
