In order to realize goal of the invention of the present utility model, the premise of loudspeaker monomer contour structure size can not increased
Under the conditions of, the size of acoustic aperture is increased, prevents air-flow caused by diaphragm oscillations from being made a noise when passing through acoustic aperture, while efficiently to sound
Circle is radiated, and the utility model provides a kind of single body construction for loudspeaker, participates in the sectional view of the present utility model shown in Fig. 1.
Loudspeaker monomer includes frame 1 and the magnetic circuit system and vibrational system that are contained in frame.Frame 1 includes bottom wall
11st, the first side wall 12 formed is upwardly extended from the edge of bottom wall 11, from the top of the first side wall 12 to the side away from frame center
Horizontal extension 13 to horizontal-extending formation and extend formed second upward by the outer ledge of horizontal extension 13
Side wall 14.Magnetic circuit system includes centring magnet 21 and center clamping plate 22, and centring magnet 21 combines the center for being fixed on bottom wall 11, in
Heart clamping plate 22 combines the top surface for being fixed on centring magnet 21.Vibrational system includes vibrating diaphragm 31 and is fixedly connected with vibrating diaphragm 31
Voice coil loudspeaker voice coil 32, the outward flange of vibrating diaphragm 31 combine the top for being fixed on second sidewall 14.The material of frame 1 can be metal or plastic cement,
Can also be that part is metal material, frame 1 can use punching press or metallic powder injection moulding process to be processed into.It is used as this
A kind of specific embodiment of utility model, the material of frame 1 is magnetic conductive metal in the present embodiment, the first side wall of frame 1
Space between 12 and centring magnet 21 and center clamping plate 22 is magnetic gap, and voice coil loudspeaker voice coil 32 is suspended in magnetic gap.When voice coil loudspeaker voice coil 32 is logical
After electricity, voice coil loudspeaker voice coil 32 vibrates in the presence of magnetic circuit system, because one end and the vibrating diaphragm 31 of voice coil loudspeaker voice coil 32 are fixed together, because
This, voice coil loudspeaker voice coil 32 can drive vibrating diaphragm 31 together to vibrate, so as to realize the sounding of vibrating diaphragm 31.The bottom wall 11 of frame 1 in the present embodiment
Play a part of conductive magnetic yoke as a part for magnetic circuit system with the first side wall 12, therefore frame 1 can generally magnetic conductive metal
Be made, can also only bottom wall 11 and the first side wall 12 for magnetic conductive metal is made and horizontal extension 13 and second sidewall 14 are modeling
Glue is made.
As shown in figure 1, at least provided with 1 acoustic aperture region 15 on the horizontal extension 13 of frame 1, as shown in Fig. 2 acoustic aperture
Several micropores 151 for running through horizontal extension 13, air-flow caused by the downward vibration of vibrating diaphragm 31 are intensively distributed with region 15
Outwards discharged by micropore 151.Preferably each micropore 151 of present embodiment is evenly arranged in acoustic aperture region 15, the hole of micropore 151
Footpath is 0.1mm.Therefore, the utility model can increase acoustic aperture region 15 by opening up more micropore 151, ensure that not
On the premise of increasing loudspeaker monomer contour structure size, maximize acoustic aperture region 15.Larger acoustic aperture region 15 can and
When discharge the air-flow that voice coil loudspeaker voice coil 22 vibrates and brought, improve the high frequency response of the frequency response curve of product, while the discharge of air-flow

Easily make a noise.On the other hand, the utility model is used as the acoustic aperture of loudspeaker monomer by opening up multiple micropores 151, because of micropore
151 aperture is smaller can not to be had to paste damping screen cloth, reduce the complexity of processing procedure.When the damping for needing regulation acoustic aperture
When, the quantity that micropore can be opened up by regulation is adjusted, and those skilled in the art can be selected as needed, this reality
With it is new to this without limit.
Further, two acoustic aperture regions 15 are symmetrically provided with horizontal extension 13, it is such a to be designed to arrange quickly
Caused air-flow and heat in the energization work of voice coil loudspeaker voice coil 32 are released, air-flow is avoided and irregularly flows and produce miscellaneous in frame 1
Sound, influence the acoustical behavior of loudspeaker monomer.
Further, the bottom wall 11 of the frame 1 in the present embodiment and the first side wall 12 rise as a part for magnetic circuit system
To the effect of conductive magnetic yoke, therefore frame 1 generally magnetic conductive metal can be made, and can also only bottom wall 11 and the first side wall 12 be to lead
Magnetic metal is made and horizontal extension 13 and second sidewall 14 are made up of plastic cement.When frame 1 is overall to be made of metal, micropore
151 directly integrally formed modes when can be by laser beam drilling or metal powder injection molding are process.
Further, the cross sectional shape of second sidewall 14 is inverted L shape, further expands the area in acoustic aperture region 15.
The shape of inverted L shape can make second sidewall 14 have relatively thin side wall and wider top, on the one hand can make acoustic aperture region 15
Width is larger, on the other hand in turn ensure that its top has wider contact area with vibrating diaphragm, ensure that the reliability of connection.
Further, the top of second sidewall 14 combines and is fixed with retainer ring 16, and vibrating diaphragm 31 passes through retainer ring 16 and second
Side wall 14 is fixedly connected.Retainer ring 16 can be made of Steel material, can also be made of other metal materials.In vibrating diaphragm 31
In forming process, HTHP when being molded using vibrating diaphragm, vibrating diaphragm 31 and retainer ring 16 by the disposable thermoset forming of hot-setting adhesive,
Then it is pasted onto the top of second sidewall 14.The loudspeaker monomer of such a structure, it is possible to increase the rigidity of vibrating diaphragm, reduce vibrating diaphragm
Oscillation crosswise, so as to improve tonequality, improve the acoustical behavior of product.
