Description
Technical field
The utility model relates to electro-acoustic product technical field, particularly a kind of microphone device.
Background technology
Along with the develop rapidly of electronic industry, the Volume design of portable electric appts more and more less, also more and more less as the volume of the microphone device of the important acoustic element of portable electric appts.But B(magnetic flux density acoustic device magnetic circuit being provided from the aspect of specification requirement) requirement of value is in continuous lifting, and in order to reach designing requirement, the external magnet in the magnetic circuit system of microphone device is designed to loop configuration more.
In the microphone device that is loop configuration at external magnet, for the firmness that guarantees that external magnet is bonding, conventionally by outer washer design all-in-one-piece circulus.The outer washer of the circulus of one can not be dodged space for voice coil leads reserves, make the space between voice coil leads and outer washer very little, if voice coil leads is still according to the unsettled setting of routine, outside when vibrational system up-down vibration, washer will produce collision with voice coil leads, causes microphone device generation noise or voice coil leads to break.
Technical staff is for fear of the generation of above-mentioned situation, the technology mode that employing sticks on voice coil leads on vibrating diaphragm avoids voice coil leads and outer washer to bump, but this kind of technology mode need to manually complete, and increased the assembling procedure of microphone device, technique is made complicated; Also the production efficiency that has reduced microphone device, has improved production cost simultaneously.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of microphone device, and this microphone device manufacture craft is simple, and production efficiency is high, and production cost is low, and sensitivity is good.
For solving the problems of the technologies described above, the technical solution of the utility model is:
, involving vibrations system and magnetic circuit system; Vibrational system comprises voice coil loudspeaker voice coil, and described voice coil loudspeaker voice coil is electrically connected to external circuit by voice coil leads; Described magnetic circuit system comprises external magnet and outer washer, described outer washer is loop configuration, described outer washer is provided with for dodging the portion that dodges of described voice coil leads, described position of dodging the corresponding described voice coil leads outlet of portion, described outer washer is towards dodging the surface of the surface of portion lower than the washer body of described outer washer described in described vibrational system one side.
Wherein, described microphone device is rectangular configuration.
As a kind of execution mode, described in being provided with, two bights of described outer washer dodge portion.
As another kind of execution mode, described in being equipped with, four bights of described outer washer dodge portion.
Wherein, described external magnet is the loop configuration that is looped around described voice coil loudspeaker voice coil periphery.
As another execution mode, the position of dodging portion described in described external magnet correspondence is disrupted configuration, described outer washer dorsad the surface of the portion that dodges of described vibrational system one side higher than the surface of described washer body.Described external magnet is comprised of four blocks of bar magnets that are separately positioned on described voice coil loudspeaker voice coil surrounding.
As another execution mode, described outer washer is the surface of the portion that dodges of described vibrational system one side and the flush of described washer body dorsad, and described external magnet is comprised of four blocks of bar magnets that are separately positioned on described voice coil loudspeaker voice coil surrounding.
As another execution mode, described outer washer is the surface of the portion that dodges of described vibrational system one side and the flush of described washer body dorsad, and described external magnet is comprised of two blocks of L shaped magnet that are separately positioned on described voice coil loudspeaker voice coil surrounding.
Adopted after technique scheme, the beneficial effects of the utility model are:
Because the outer washer of the utility model microphone device is provided with for dodging the portion that dodges of described voice coil leads, dodge the position of the corresponding voice coil leads outlet of portion, outer washer towards the surface of the portion that dodges of vibrational system one side lower than the surface of the washer body of outer washer.The portion of dodging that on outer washer, corresponding voice coil leads goes out line position setting has increased the space between outer washer and voice coil leads, when vibrating, vibrating diaphragm can guarantee can not bump between outer washer and voice coil leads, therefore this of outer washer kind of structure is not needing that voice coil leads is pasted to the problem that just can avoid the noise that produces because of voice coil leads and the collision of outer washer or voice coil leads to break on vibrating diaphragm.Owing to not needing that voice coil leads is pasted on vibrating diaphragm, simplified the assembling procedure of microphone device, reduce the input of artificial and frock, thereby improved production efficiency, reduced production cost; Also alleviated in addition the weight of vibrating diaphragm, thereby the sensitivity that has also improved microphone device has promoted the acoustical behavior of microphone device.
Because voice coil leads only has two, respectively from two bight outlets of voice coil loudspeaker voice coil, therefore two bights of the corresponding voice coil leads outlet of washer are outside provided with the portion of dodging and just can meet design requirement, but need workman when assembling outside adjustment the direction of washer guarantee the portion that dodges and voice coil leads to go out line position corresponding.Therefore four of washer bights are all provided with the portion of dodging outside, workman does not need to adjust the direction of outer washer when assembling, just can guarantee the portion that dodges and voice coil leads to go out line position corresponding, further simplified assembling procedure, further improved the production efficiency of product.
In sum, the utility model microphone device has solved the technical problem that in prior art, microphone device packaging technology is complicated, production cost is high.The utility model microphone device packaging technology is easy, and production cost is low, and production efficiency is high, highly sensitive.
