Description
[technical field]
The utility model relates to microphone device, especially relates to a kind of SMD miniature moving-coil type microphone device.
[background technology]
At present, the miniature moving-coil type microphone device is widely used in mobile phone, notebook computer, game machine etc., conventional miniature moving-coil type microphone device design principle mature production technology, add that material is suitable, all help market on the performance, on the price and accept, but these microphone devices can not use in the very high SMT equipment of automaticity, and other most electronic components, taked SMD structure already as Resistor-Capacitor Unit, IC etc., can improve the production efficiency of assembling effectively like this! Therefore, it is also necessary to develop SMD microphone device.
Because modern small-sized fashion electrical equipment smaller volume, its applied microphone device is all smaller, as mobile phone, maximum SPEAKER size also is no more than 20mm, but because the fashion of function, its performance requirement is very high, it is at present ripe that what be widely used is DYN dynamic microphone device, regrettably such microphone device can not resemble IC, resistance etc. can utilize REFLOW OVEN to be used for producing in enormous quantities, mainly be that the interior temperature characterisitic of its effective scope of application is compared mutually far short of what is expected with REFLOW OVEN, in case through REFLOW OVEN, irreversible decline or damage will appear in its performance, Fig. 5 is the temperature characteristics of typical R EFLOW OVEN, and under the high temperature of its certain time, normal miniature moving-coil microphone device is irreversible performance reduction or damage all to occur.This mainly is that the material of its use can't reach this temperature requirement, perhaps use general high-temperature material after, its performance does not far reach desired performance.
Existing microphone device kind is more, from electroacoustic performance, and moving-coil type product optimum.Because present versatile material characteristic and manufacture craft restriction, conventional miniature moving-coil type microphone device working temperature can only be between pact-40-+85 ℃, if temperature too high especially as 220 ℃ of (common Reflow Soldering temperature) above high temperature under, the product electroacoustic performance will seriously descend or complete failure.Fig. 4 a～Fig. 4 h is several connected modes of common miniature moving-coil type microphone device, and the shortcoming that they are common is exactly all can not operate under the hot properties of Fig. 5, also can't use in SMT equipment.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of SMD miniature moving-coil type microphone device, can bear the hot properties of REFLOW OVEN, keep moving-coil type microphone device electroacoustic performance, can be used for the SMD miniature moving-coil type microphone device of SMD of SMT assembly technology again.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of SMD miniature moving-coil type microphone device, comprise a basin frame and a driver part, driver part is made of vibrating diaphragm, the magnetic circuit system that is bonded in the voice coil loudspeaker voice coil on the vibrating diaphragm and drives voice coil loudspeaker voice coil, driver part be installed in the basin frame and the protecgulum shutoff of an end face that is set at the basin frame in the basin frame, the recessed dew in described basin frame other end and form welding stage is provided with one group of weld tabs that can be beneficial to the SMT assembling on the welding stage.
Further improvement in the technical proposal is:
Described weld tabs is the copper sheet of zinc-plated or slicker solder, and is injected into one with the basin frame, and all weld tabs are in same plane.
Described basin frame, voice coil loudspeaker voice coil, vibrating diaphragm are that exotic material is made.
Also have an acoustic conduit and be connected in the operatic tunes on the end product, the operatic tunes can be a phonate hole.
The beneficial effects of the utility model are: owing to the SMD miniature moving-coil type microphone device of the utility model forms an assembly welding platform at the recessed dew of the end face of basin frame, one assembly welding sheet is set on the welding stage, change the connected mode of voice coil loudspeaker voice coil and extraneous signal into pad formula structure, therefore can in SMT equipment, use, can bear the hot properties of REFLOW OVEN.The operatic tunes on the acoustic conduit connection panel and the SMD microphone device on the pcb board, can obtain acceptable fully or the better characteristic of performance, such application brings the bigger degree of freedom also for the putting position of SMD mini-sound device in end product, can make the position of SMD microphone device on pcb board, freely be provided with, its frequency response curve in audiorange is more smooth, has improved properties of product.
