Abstract

The utility model relates to a kind of vibrating diaphragms, it includes top dome and the ring around top dome setting, the ring includes outside ring inner edge and the ring opposite with the ring inner edge, thickness is thinner than the ring inner edge thickness outside the ring, specific size changes the transition in a manner of gradual change, and the utility model additionally provides a kind of loudspeaker including the vibrating diaphragm.The adjustable diaphragm structure intensity of the vibrating diaphragm of the utility model improves the symmetry of vibrating diaphragm or more amplitude, improves product and waves, and then reduce the distortion factor of speaker product, promotes the sound quality of speaker product.

Description

A kind of vibrating diaphragm and the loudspeaker with the vibrating diaphragm

Technical field

The utility model relates to electroacoustic field, particularly a kind of vibrating diaphragm for improving structure and raising with the vibrating diaphragm Sound device.

Background technique

With the fast development of electronic information technology, more and more microphone devices are applied in each electronic product, especially It is the mobile communication equipment of widely people's application, and people do not require nothing more than it to miniaturization, more requires its sound effect high Quality, it is undistorted.And core component of the vibrating diaphragm as microphone device, the quality of design directly affect the property of acoustical device Energy.

Vibrating diaphragm generally includes top dome and the ring around top dome setting, and the ring is usually symmetrical cyclic structure, With fixed structural strength, there are problems that amplitude asymmetry causes voice distortion to vibrating diaphragm up and down.

Therefore, it is necessary to provide one kind new vibrating diaphragm and loudspeaker to solve the above problems.

Utility model content

The purpose of the utility model is to provide a kind of vibrating diaphragms with high performance structures and one kind to have preferable acoustical behavior Loudspeaker.

The utility model is realized through the following technical scheme: a kind of vibrating diaphragm comprising top dome and surround the ball The ring of setting is pushed up, the ring includes outside ring inner edge and the ring opposite with the ring inner edge, and the ring is in place It is equipped with the interconnecting piece being connected with the top dome on one side close to top dome in the ring inner edge, the ring is being located at the ring Outside is equipped with holding parts far from the top dome on one side, and the holding parts are fixedly connected for vibrating diaphragm and outer member, described Thickness is thinner than the ring inner edge thickness outside ring.

Preferably, the thickness of ring transition in a manner of gradual change.

Preferably, the ring and the top dome can be integrated, be also possible to fission.

Preferably, the diaphragm materials are high molecular materials.

Preferably, the diaphragm materials are silica gel, rubber, PEEK or TPU.

A kind of loudspeaker comprising in forming the frame of accommodating space, being housed in the accommodating space and be individually fixed in The magnetic circuit system and vibrational system of the frame, the vibrational system include voice coil and use any one described in claim 1-5 Vibrating diaphragm described in item claim.

Preferably, the ring is raised to the direction far from magnetic circuit system.

The utility model has the advantage that the adjustable structural strength of the vibrating diaphragm of the utility model, improves vibrating diaphragm or more The symmetry of amplitude improves product and waves, reduces the distortion factor of speaker product, promote the sound quality of speaker product.

Specific embodiment

The utility model is described in further detail below by specific embodiment combination attached drawing, so as to more preferably Ground understands the advantages of the embodiment of the utility model and its various aspects.Below in an example, with the right and left of attached drawing paper To for horizontal direction, using the up and down direction of attached drawing paper as vertical direction.Additionally, it is provided the purpose of following specific embodiments is Thorough explanation is become apparent from convenient for the content to the utility model, rather than limitations of the present invention.

As shown in Figs. 1-5, the utility model loudspeaker 100 comprising form the frame 5 of accommodating space 50, be housed in institute The magnetic circuit system 1 and vibrational system 2 of the frame 5 are stated in accommodating space 50 and are individually fixed in, the vibrational system 2 includes sound Circle 3 and vibrating diaphragm 4, the vibrating diaphragm 4 include centrally located top dome 41 and the ring 42 around top dome setting, and the ring is to separate The direction protrusion of magnetic circuit system 1.Ring is divided into outside ring inner edge 422 and ring 423 two by the vertex of the ring cambered surface Point, the ring inner edge is close to the top dome 41.The ring be located at ring inner edge close to one end of the top dome be equipped with The connected interconnecting piece 421 of top dome, the interconnecting piece 421 include upper surface 421a and lower surface corresponding with the upper surface The upper surface of 421b, the interconnecting piece 421 are fixedly connected with the top dome, and the lower surface of the interconnecting piece 421 is far from described One end of ring is equipped with the step 421c being recessed upwards, and the voice coil 3 is fixed on the horizontal plane of the step 421c.The ring Holding parts 414 are equipped with being located at one end outside ring far from top dome, the holding parts connect for vibrating diaphragm 4 and the fixed of frame 5 It connects.It should be noted that in the present embodiment ring with top dome be it is seperated, in other embodiments, ring and top dome can also To be integrated.The top dome 41 is also possible to cambered surface either plane.4 material of vibrating diaphragm can be silica gel, rubber Glue, PEEK, TPU or other high molecular materials.

In the present embodiment, 423 thinner than 422 thickness of ring inner edge outside the ring, ring thickness with The intersection mistake of the mode of gradual change outside 423 and holding parts 424 from the intersection of interconnecting piece 421 and ring inner edge 422 to ring It crosses, the ring dimensional thickness variation range is indefinite, can be adjusted according to actual product.The utility model ring size is by interior thickness To outer thin variation, adjustable structural strength improves the symmetry of vibrating diaphragm or more amplitude, improves product and waves, reduces loudspeaking The distortion factor of device product improves the sound quality of speaker product.

Above-described is only the embodiments of the present invention, it should be noted here that for the ordinary skill of this field For personnel, without departing from the concept of the present invention, improvement can also be made, but these belong to it is practical Novel protection scope.
