Description

High frequency mobile phone vibrating diaphragm

Technical field

The utility model relates to a kind of audio element, specifically, relate to a kind of high frequency mobile phone vibrating diaphragm.

Background technology

Present mobile phone industry development is more and more quicker, wherein people are more and more higher for the requirement of mobile phone tonequality, in order to enhance competitiveness in industry, demand for high-fidelity tweeter is also more and more higher, be limited to again the size of mobile phone simultaneously, stablize sounding under being difficult to accomplish to ensure high frequency prerequisite undistorted, volume again can not be excessive, and this problem always annoyings developer.

In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, thus provides that a kind of design science, volume are little, vibration is stable, the high frequency mobile phone vibrating diaphragm of not easily distortion.

To achieve these goals, the technical scheme that the utility model adopts is: a kind of high frequency mobile phone vibrating diaphragm, comprise PEEK thin layer and the casing play being pasted onto this PEEK thin layer center, described casing play comprises PEI foamed board and is clipped in the aluminium foil layer of these PEI foamed board both sides, described PEEK thin layer is formed towards the annular projection of described casing play around described casing play, the corner of the corresponding described casing play of annular projection of described PEEK thin layer is respectively equipped with pleat line, the projection direction of described pleat line is consistent with the projection direction of described annular projection, the outermost end of described PEEK thin layer is fixed part.

Described on base, the annular projection between the pleat line at adjacent two jiaos of places is provided with the reinforcement that reverse indent is formed.

Described on base, the inner terminal of described fold connects with the outer end of described casing play, and the outermost end of described fold extends on fixed part.

The utility model hinge structure has substantive distinguishing features and progress, specifically, mute two aluminium casing play that the aluminium foil layer that the utility model adopts PEI foamed board and is clipped in these PEI foamed board both sides is formed, general by one side blacking toward the outer side, better with the colour consistency of stereo set, this casing play has stable, thermal coefficient of expansion is little, very use during applicable dither, PEEK thin layer has good toughness and rigidity and fatigue durability, also be the excellent material manufacturing high frequency mobile phone vibrating diaphragm, both combine, the demand of dither can be adapted to, PEEK offers annular projection, projection direction is towards the one side posting casing play, pleat line is offered at corner place, pleat line is towards consistent with annular projection, outermost end is fixed part, this is because fixed part is fixed on after on audio amplifier skeleton, the direction of jut and pleat line is outwardly, when voice coil loudspeaker voice coil promotion high frequency mobile phone vibrating diaphragm outwards vibrates, the effect of balance outward thrust can be reached, thus make vibration stable, especially the successful of pleat line, the non-deformability of annular projection can be strengthened, thus balance vibration, reach the distortionless object of sounding.

Annular projection does not have the part of pleat line the reinforcement of reverse indent is set, further enhance the stabilizing power of annular projection.

Further, the inner of pleat line is concordant with the outer end of casing play, the outer end of pleat line extends on fixed part, its objective is and increases pleat line length, strengthen the effect that pleat line plays, under normal circumstances, be all adopt the height increasing pleat line to realize, but be limited to the size in space, pleat line is increased, also can reach same object, and accomplish to strengthen its stability when not taking up room as far as possible.

It has design science, volume is little, vibration is stable, the advantage of not easily distortion.

Embodiment

Below by embodiment, the technical solution of the utility model is described in further detail.

As shown in Figure 1-Figure 3, a kind of high frequency mobile phone vibrating diaphragm, comprise PEEK thin layer 1 and the casing play 2 being pasted onto this PEEK thin layer 1 center, described casing play 2 comprises PEI foamed board 3 and is clipped in the aluminium foil layer 4 of these PEI foamed board 3 both sides, make it have excellent stability, thermal coefficient of expansion is little, PEEK thin layer 1 has toughness and good rigidly, the advantage that fatigue durability is splendid, described PEEK thin layer 1 is formed towards the annular projection 6 of described casing play 2 around described casing play 2, the corner of the corresponding described casing play 2 of annular projection 6 of described PEEK thin layer 1 is respectively equipped with pleat line 5, its object is to the intensity strengthening high frequency mobile phone vibrating diaphragm entirety, make vibrations more stable, the projection direction of described pleat line 5 is consistent with the projection direction of described annular projection 6, the strength of high frequency mobile phone vibrating diaphragm is promoted for balancing voice coil loudspeaker voice coil, the outermost end of described PEEK thin layer 1 is fixed part 7, the inner terminal of described fold connects with the outer end of described casing play 2, the outermost end of described fold 5 extends on fixed part 7, lengthen the length of high frequency mobile phone vibrating diaphragm, thus further strengthen the structural strength of high frequency mobile phone vibrating diaphragm, ensure the stable of vibration processes, thus avoid distortion.

As shown in Figure 4, in other embodiments, the annular projection 6 between the pleat line 5 at adjacent two jiaos of places is provided with the reinforcement 8 that reverse indent is formed, and object strengthens high frequency mobile phone further to shake film strength,

Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to embodiment of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
