So as to improve the tonequality of loudspeaker monomer, reliability and the sensitivity of loudspeaker monomer are improved.
Brief description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 shows the sectional view of the utility model.
Embodiment
In order to illustrate more clearly of the utility model, the utility model is done into one with reference to preferred embodiments and drawings
The explanation of step.Similar component is indicated with identical reference numeral in attached drawing.It will be appreciated by those skilled in the art that below
Specifically described content is illustrative and be not restrictive, and should not limit the scope of protection of the utility model with this.
In order to realize the goal of the invention of the utility model, the premise of loudspeaker monomer contour structure size can not increased
Under the conditions of, the size of acoustic aperture is increased, is made a noise when preventing the air-flow that diaphragm oscillations produce from passing through acoustic aperture, while efficiently to sound
Circle radiates, and the utility model provides a kind of single body construction for loudspeaker, and the sectional view of the utility model is shown referring to 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 side wall 12 formed is upwardly extended by 11 edge of bottom wall and is extended obliquely upward (i.e. from frame side by the top of side wall 12
The top of wall is extended obliquely out to the direction away from 12 top of frame side wall) formed extend obliquely out portion 13.During magnetic circuit system includes
Heart magnet 21 and center clamping plate 22, centring magnet 21 combines the center for being fixed on bottom wall 11, during the combination of center clamping plate 22 is fixed on
The top surface of heart magnet.Vibrational system includes vibrating diaphragm 31 and the voice coil loudspeaker voice coil 32 being fixedly connected with vibrating diaphragm 31, the outer edge knot of vibrating diaphragm 31
Close the top for being fixed on the portion of extending obliquely out 13.As a kind of specific embodiment, the material of frame 1 is to lead in the present embodiment
Magnetic metal, the gap between the side wall 12 and centring magnet 21 and center clamping plate 22 of frame 1 is magnetic gap, and voice coil loudspeaker voice coil 32 is suspended in magnetic
In gap.After voice coil loudspeaker voice coil 32 is powered, voice coil loudspeaker voice coil 32 vibrates under the action of magnetic circuit system, since one end and the vibrating diaphragm 31 of voice coil loudspeaker voice coil 32 are solid
Surely link together, therefore, voice coil loudspeaker voice coil 32 can drive vibrating diaphragm 31 together to vibrate, so as to fulfill the sounding of vibrating diaphragm 31.The utility model
In frame 1 bottom wall 11 and side wall 12 play the role of conductive magnetic yoke as a part for magnetic circuit system, therefore frame 1 can be whole
Body is made of magnetic conductive metal, can also only the portion of extending obliquely out 13 is made for magnetic conductive metal in bottom wall 11 and side wall 12 is plastic cement system
Into.
As shown in Figure 1, extending obliquely out for frame 1 at least offers an acoustic aperture 14 in portion 13, the axis of acoustic aperture 14 is vertical
In the portion that extends obliquely out 13.Under the premise of the appearance and size of loudspeaker monomer is not increased, extend obliquely out than horizontal-extending distance
It is long, the acoustic aperture 14 of larger aperture can be opened up in the portion that extends obliquely out 13, therefore, the acoustic aperture 14 of larger aperture can arrange in time
Bleed off the air-flow that voice coil loudspeaker voice coil 32 is vibrated and brought, the discharge of air-flow can take away the heat of the generation of voice coil loudspeaker voice coil 32, while air-flow by compared with
It is not easy to make a noise during the acoustic aperture 14 of large aperture.
Further, extend obliquely out and two acoustic aperture 14 are symmetrically offered in portion 13, such a design can discharge quickly
Go out in 32 energization work of voice coil loudspeaker voice coil the air-flow and heat produced, avoid air-flow and irregularly flowed in frame 1 and produce noise,
Influence the acoustical behavior of loudspeaker monomer.
Further, the bottom surface combination for extending obliquely out portion 13 is fixed with damping screen 15, and damping screen 15 covers acoustic aperture 14.It is larger
Although the acoustic aperture 14 in aperture easy to air-flow by, also reduce the acoustic resistance of loudspeaker, have impact on the low-frequency effect of loudspeaker, because
This covers damping screen to increase acoustic resistance in acoustic aperture 14, improves the tonequality of loudspeaker.Alternatively, damping screen 15 uses non-metallic material
Expect the screen cloth being knitted to form, screen cloth has relatively large acoustic resistance, and has more preferable binding ability with frame 1.This
In embodiment, screen cloth combines the lower surface for being fixed on the portion of extending obliquely out 13 by way of stickup, simplifies processing technology, carries
High production speed, and the yield rate processed is higher.
Further, the percent opening of damping screen 15 also has an impact acoustic resistance, to ensure the tonequality of loudspeaker monomer, damping screen
For 15 percent opening usually 1%~20%, i.e., the every square millimeter area perforate for having 1%~20%, percent opening can influence product
Actual vapor permeation area, while percent opening also has an impact the combination situation of damping screen and housing, and those skilled in the art can root
Percent opening is made choice according to being actually needed.
The utility model additionally provides a kind of electronic equipment, which includes above-mentioned loudspeaker monomer.
Obviously, above-described embodiment of the utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to the embodiment of the utility model, for those of ordinary skill in the field, in described above
On the basis of can also make other variations or changes in different ways, all embodiments can not be exhaustive here,
It is every to belong to obvious changes or variations that the technical solution of the utility model is extended out still in the utility model
The row of protection domain.
