Abstract

The utility model provides a vibrating diaphragm, comprising a tightening part, a maintaining part and a connecting part which is connected with the tightening part and the maintaining part; the vibrating diaphragm further comprises folds arranged in the connecting part, and the folds are divided into a I cluster and a II cluster, the distributing density of the folds in the I cluster is more than that of the II cluster. The performances of the vibrating diaphragm and the louder speaker are improved by the utility model.

Description

Vibrating diaphragm and use the loud speaker of this vibrating diaphragm

Technical field

The utility model relates to a kind of electroacoustic component and a kind of electroacoustic transducer, relates in particular to a kind of electroacoustic vibrating elements and a kind of loud speaker.

Background technology

For electroacoustic transducer, as loud speaker, receiver etc., the structure of vibrating elements is the key factor that influences its sounding effect.Especially for loud speaker, the structure of vibrating diaphragm is the key factor that influences its sounding effect, thereby is a continuous important topic of development in the loud speaker field to the design of vibrating diaphragm always.Be that example is told about correlation technique only below with the vibrating diaphragm in the loud speaker.In the correlation technique, on the vibrating diaphragm M1 of loud speaker fold S1 is arranged, this fold S1 is symmetrical, as the fold S1 of the vibrating diaphragm axial symmetry about vibrating diaphragm M1, sees also Fig. 1.The vibrating diaphragm of this kind structure from the principle, helps keeping the balance of loud speaker when work, obtains good performance.But in practice, because the influence of miscellaneous part or technology, as the restriction owing to structure, phonate hole can't be accomplished symmetrical structure; Because the influence of the technologies such as leading-out terminal sealing processing of voice coil line, make the asymmetric of loud speaker integrality, imbalance, thus cause the speaker product degradation, increase as distortion, pure tone is bad etc.

The utility model content

The purpose of this utility model is to provide a kind of vibrating diaphragm, to solve the technical problem of vibrating diaphragm poor performance; The utility model also provides a kind of loud speaker, to solve the technical problem of speaker product poor performance.

For reaching above-mentioned technical purpose, the technical scheme that the utility model provides is:

A kind of vibrating diaphragm, described vibrating diaphragm comprises a fastening part, a retaining part and the coupling part that is connected described fastening part and retaining part; Described vibrating diaphragm also comprises the fold that is arranged in the described coupling part, and described fold is divided into that I troops and II troops, the density that fold distributed during the density that fold distributed during I trooped was trooped greater than II.

Preferably, described vibrating diaphragm is a runway shape, and the fastening part of vibrating diaphragm, retaining part and coupling part are and the corresponding runway shape of described vibrating diaphragm.

Preferably, the angle during described I troops between the adjacent pleats is 6 degree, and the angle during described II troops between the adjacent pleats is 15 degree.

Preferably, described extended line that I troops or II troops comes together on the center line of vibrating diaphragm.

The utility model also provides a kind of loud speaker, it is characterized in that, described loud speaker comprises aforesaid vibrating diaphragm.

The beneficial effects of the utility model are: broken the symmetrically arranged method of correlation technique owing to be arranged on the vibrating diaphragm setting of fold, the miscellaneous part or the technology that match with its structure in the cooperation, when cooperating with miscellaneous part, can really realize vibrating diaphragm symmetry and balance, thereby make vibrating diaphragm reach good performance; The utility model also provides a kind of loud speaker, because this loud speaker comprises the as above vibrating diaphragm of structure, this vibrating diaphragm cooperates miscellaneous part or the technology that matches with its structure again, can realize the symmetry and the balance of loud speaker integral body, thereby improve the performance of loud speaker.

Description of drawings

Fig. 1 is the vibrating diaphragm of a kind of symmetrical structure in the correlation technique;

Fig. 2 is the vibrating diaphragm of a kind of unsymmetric structure of providing of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

See also Fig. 2, the vibrating diaphragm M that the utility model provides, vibrating diaphragm M comprise a fastening part B, a retaining part H and the coupling part C that is connected fastening part B and retaining part H; Vibrating diaphragm M also comprises the fold S that is arranged in the C of coupling part, and fold S is divided into that I troops and II troops, the density that fold distributed during the density that fold distributed during I trooped was trooped greater than II.In the preferred embodiment that the utility model provides, can be that the boundary is divided into fold S that I troops and II troops with the minor axis of vibrating diaphragm M or major axis.Fold S also can extend to the outside of coupling part from the inside of coupling part C, and the inside of above coupling part C is the edge near the vibrating diaphragm center, and the outside of coupling part C is the edge at principle vibrating diaphragm center.

In the preferred embodiment that the utility model provides, vibrating diaphragm M is a runway shape, and the fastening part B of vibrating diaphragm M, retaining part H and coupling part C are and the corresponding runway shape of described vibrating diaphragm M.But vibrating diaphragm is not limited to runway shape, as also being circle.

In the preferred embodiment that the utility model provides, the angle that I troops between the adjacent pleats S is 6 degree, and the angle that II troops between the adjacent pleats S is 15 degree.

In the preferred embodiment that the utility model provides, the troop extended line of fold S of I comes together in 1 e on the center line of vibrating diaphragm M; The troop extended line of fold S of II comes together in 1 f. on the center line of vibrating diaphragm M

The fastening part B of vibrating diaphragm M is positioned at the outside of retaining part H among the embodiment that the utility model provides, retaining part H is positioned at fastening part B inside, but in fact, also can be the inside that the fastening part B of vibrating diaphragm M is positioned at retaining part H, retaining part H be positioned at fastening part B outside.

The utility model also provides a kind of loud speaker, and this loud speaker comprises aforesaid vibrating diaphragm.

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.
