Any and all combinations of one or more relevant Listed Items.
Below in conjunction with the accompanying drawings, illustrate the better embodiment of the utility model.
As illustrated in fig. 1 and 2, a kind of receiver, including shell, vibrating mechanism, electromagnetic drive mechanism, sound tube 400 and micro-
Circuit board 500.
Shell includes spaced first shell 110 and second shell 120.First shell 110 include the first bottom and
The first bending part being connect with the first bottom, second shell 120 include the second bottom and the second bending being connect with the second bottom
Portion.The sound outlet hole being connect with the sound tube 400 being arranged outside shell is equipped in first shell 110 or second shell 120.
The material and specification of shell can be selected according to actual demand.In one embodiment, first shell 110 and/
Or second shell 120 can be the metal materials such as magnetic shielding material, such as iron, copper, manganese, shell is reduced as magnetic shield at this time
External interference.
Blade of a sword iron is generally comprised in traditional receiver, blade of a sword iron and vibration section more and more thinner however as the thickness of receiver
214 spacing are compressed, but compressing spacing can be limited by sounding effect and quality.In another embodiment,
The material of one shell 110 and/or second shell 120 is to increase magnetic material, increases magnetic material and may be, for example, common blade of a sword iron material.At this time
First shell 110 and/or second shell 120 can be used as substitute blade of a sword iron use, to reduce the use of blade of a sword iron, further be thinned by
Talk about device.
Vibrating mechanism includes vibrating diaphragm mechanism and vibrating reed 210.Vibrating reed 210 is lamellar structure and includes fixed part and vibration
Portion 214 is set between first shell 110 and second shell 120.Vibrating reed 210 can respectively with first shell 110 and
The EDGE CONTACT of two shells 120 connects.In the present embodiment, close to first shell 110 and the on the fixed part of vibrating reed 210
The part of two shells 120 respectively with corresponding first shell 110 and second shell 120 connection and can with first shell 110 and
Second shell 120 collectively forms accommodating chamber.Preferably, vibrating reed 210 can pass through the modes such as binder or welding and first shell
110 and second shell 120 connect.Certainly, vibrating reed 210 can also pass through the other modes such as grafting or buckle and first shell 110
It is connected with second shell 120.In this way, since the exposure of vibrating reed 210 is set between first shell 110 and second shell 120, and
The non-concealed inside for being set to first shell 110 and second shell 120, so during receiver actual assembled, positioning peace
Dressing is easy, can not only reduce the installation assembly process inside housings of vibrating reed 210 and difficulty, but also can reduce receiver height
The size in direction realizes being thinned for receiver, improves the consistency of packaging efficiency and product.
In one embodiment, vibrating reed 210 can by way of binder with first shell 110 and second shell 120
It is tightly connected.It is connected and sealed for example, contact gap of the fluid sealant to the fixed part of vibrating reed 210 with shell can be used.
In one embodiment, the shape of first shell 110 and second shell 120 can match with the shape of the fixed part of vibrating reed 210,
Contact gap of the fixed part of vibrating reed 210 with shell can be so reduced, and then reduces the usage amount of fluid sealant.Due to fluid sealant
Usually high molecular material can have problem of aging, and vibrating reed 210 and shell can be improved in the usage amount by reducing fluid sealant
Stability is sealed, the service life of entire receiver is extended.
In general, vibrating reed 210 is seal cavity with first shell 110 and 120 constituted accommodating chamber of second shell.In this way,
When after vibrating reed 210 being connect with first shell 110 and second shell 120 there is also compared with big gap, then need filling a large amount of
Fluid sealant is tightly connected with realizing.
Specifically, as shown in Figure 1, first shell 110 and second shell 120 are symmetrically arranged common rectangular lid,
Vibrating reed 210, vibrating reed 210 and first shell 110 and second shell 120 are set between first shell 110 and second shell 120
Junction can be attached by binder.Since the size of vibrating reed 210 limits, in the left part of first shell 110 and the
Without friction 210 between the left part of two shells 120, it is connected and sealed at this time by a large amount of fluid sealant.
Certainly, the lid of first shell 110 and second shell 120 or unsymmetric structure.In this way, can be by adjusting the
The respective size of one shell 110 and second shell 120 to change the size of corresponding upper and lower cavities, and then can get different
Sounding effect.Such as the high frequency output of receiver can be inhibited, and then improve sound quality by the size of reduction upper cavity.
In addition to this, first shell 110 and second shell 120 may also be configured to special-shaped lid, and lid can be one end at this time
It can fasten, there are the gaps that can accommodate 210 fixed part of vibrating reed for the other end.The fixed part of vibrating reed 210 is arranged in the seam
Sealing accommodating chamber is formed in gap and by being tightly connected.Specifically, the edge shape and size of lid can match vibrating reed 210
Shape and size, such as the edge shape of lid can be L-shaped or inverted L-shaped.It so can avoid existing compared with big gap, it is close to reduce
The usage amount of sealing and simplified sealing process.
It is mechanical oscillation that vibrating reed 210, which is by electromagnetic energy, is vibrated, is made a sound to be transmitted to vibrating diaphragm mechanism
Important component.In conventional design, vibrating reed 210 be usually U-shaped structure, it is not only complicated, and manufacture craft at
This height, the application of the thicker receiver that can not adapt to small size of size.In the present embodiment, vibrating reed 210 is lamellar structure
And include fixed part and vibration section 214.Lamellar structure can be E types structure or other lamellar structures.Such vibrating reed 210 is not only made
Make simple for process, and parts cost can be reduced；The integral thickness of receiver can be effectively reduced, volume is reduced, increases it
Application in the receiver of small size.
In one embodiment, fixed part includes at least the first arm 211, the second arm 212 and third arm 213, the first arm 211
