Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described corresponding accompanying drawing.Obviously, described embodiment is only the present invention one
Section Example, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out under the premise of creative work the every other embodiment obtained, belong to the scope of protection of the invention.
Below in conjunction with accompanying drawing, the technical scheme that various embodiments of the present invention provide is described in detail.
Fig. 2 is refer to, the embodiment of the present invention discloses the loudspeaker of a kind of electronic equipment, and disclosed loudspeaker includes casing
100 are arranged in casing 100 with vibration main body 200, vibration main body 200, and sender 110 is laid with casing 100.
Vibration main body 200 includes vibration cavity 210 and multiple air-vents 220, and multiple air-vents 220 are used to connect vibration cavity
210 and the inner chamber 120 of casing 100, during work, the vibration of vibration main body 200 can drive the air in vibration cavity 210
Flowing, and then the air flow in the inner chamber 120 for passing through the drive casing 100 of air-vent 220, and then lift low frequency performance.
In the present invention, multiple air-vents 220 can be so-called circumferentially to refer in the circumference discrete distribution of vibration main body 200
It is the edge bearing of trend along vibration main body 200.Casing 100 includes the inwall with multiple Relative distributions of air-vent 220.One kind tool
In the embodiment of body, the inwall of casing 100 corresponds with multiple air-vents 220 to be distributed.In the application, air-vent 220 with
The distance between inwall corresponding thereto is hole wall distance.In multiple air-vents 220, the circulation area of air-vent 220 is saturating with this
The hole wall distance of stomata 220 is inversely proportional.That is, air-vent 220 and the distance between relative inwall are smaller, the air-vent
220 circulation area is bigger；Air-vent 220 and the distance between relative inwall are bigger, and the circulation area of the air-vent 220 is got over
It is small.
It should be noted that in the present invention, the circulation area of air-vent 220 refers to that air-vent 220 penetrates direction at it
On, the area of the cross section of the negotiability of air-vent 220 is determined, so-called cross section is perpendicular to the insertion direction of air-vent 220
Section.If air-vent 220 is uiform section hole, air-vent 220 can represent its circulating face in the insertion any cross section in direction
Product.If air-vent 220 is variable cross-section hole, the circulation area of air-vent 220 is then decided by the area at cross-sectional area minimum position.
In the procedures of establishment of reality, the inwall relative with air-vent 220 may have it is multiple, as shown in Fig. 2 some is ventilative
Hole 220 is towards the junction of two inwalls of casing 100, in such cases, in relative with air-vent 220 two inwalls, compared with
The distance between remote inwall and the air-vent 220 determine air-vent 220 circulation area, apart from air-vent 220 farther out in
Space corresponding to wall is larger, and the mobility of air is preferable in space, can suitably reduce the circulation area of air-vent 220.
Loudspeaker disclosed in the embodiment of the present invention, tune is implemented to the circulation area of the air-vent 220 in vibration main body 200
It is whole so that the circulation area of air-vent 220 determines by the distance between air-vent 220 and corresponding inwall of casing 100,
Distance is more big, illustrates that inner chamber 120 and the space inner air flow at the 220 corresponding position of air-vent are preferable, on the contrary, distance is got over
It is small, illustrate that air flow property is poor, corresponding air-vent 220 can design larger circulation area, and then balance vibration main body
The air flow situation of 200 each air-vents 220, the vibrational state of balance vibration main body 200 is finally reached, alleviates vibration main body
200 produce polarization and are influenceed to caused by sounding.It can be seen that loudspeaker disclosed in the embodiment of the present invention can solve the problem that current raise one's voice
The problem of device causes voice quality poor in the presence of more serious polarization.
As shown in Fig. 2 being set for the ease of the position of loudspeaker, the sender 110 of casing 100 is located at the one of casing 100
Side.Preferably, vibration main body 200 is arranged on position relative with sender 110 in the inner chamber 120 of casing 100.
