Detailed description of the invention
Below in conjunction with accompanying drawing and a preferred embodiment, technical scheme is further described.
Refering to Fig. 2-4, this preferred embodiment relate to a kind of improved design for bone conduction type sonifer and loudspeaker arrangement
In dynamic ferrum microphone unit, it includes conduct vibrations device 1, armature 2, vibrating diaphragm 3, conducting magnet core 4, flat thin magnet 5, electromagnetic induction
Coil 6, electromagnetic shielding shell 7, magnetic induction coil holding wire 8, outlet sound mouth 9 and connector more than 10 part composition.
Specifically, armature 2, conducting magnet core 4, flat thin magnet 5 and electromagnetic induction coil 6 are by resistance, laser or supersonic welding
Connecing connect fixing with the mode of adhesive bonding, composition drives magnet mechanism, the conducting magnet core 4 in this driving magnet mechanism with shake
Film 3 is fixing to be connected, and armature 2 in this driving magnet mechanism is then fixing with one end of conduct vibrations device 1 to be connected, conduct vibrations
Device 1 is connected by its other end is fixing with electromagnetic shielding shell 7.It is provided with opening 10, for passing with vibration on this electromagnetic shielding shell 7
Lead the connection of device 1.
It addition, the surrounding of vibrating diaphragm 3 is, on the airtight inwall being fixed on electromagnetic shielding shell 7 of adhesive, to collectively form from electric energy
The energy converting system of mechanical energy Zhongdao acoustic energy is arrived again to magnetic energy.
When this moving-iron microphone cell operation, ac signal can be by the signal wire slots being exposed to electromagnetic shielding shell 7
Outer electromagnetic induction coil holding wire 8 is incoming, thus by electromagnetic induction coil 6, and thus produce electromagnetic induction effect and feel
Raw alternating magnetic field, alternating magnetic field can magnetize the armature 2 being placed in electromagnetic induction coil 6, conducting magnet core 4 and flat thin magnet 5, armature 2
Can be according to homopolar-repulsion, there is push-and-pull action in principle and flat thin magnet 5 that heteropole is attracting, thus drives and be fixedly connected on armature 2
Conduct vibrations device 1 produce vibration displacement along the direction orthogonal with armature 2, when vibration displacement travel to via connector 10 with
When the other end of conduct vibrations device 1 fixes the electromagnetic shielding shell 7 of connection, its opposition can be along conduct vibrations device 1 time
Pass, promote the driving magnet mechanism of armature 2, conducting magnet core 4, flat thin magnet 5 and electromagnetic induction coil 6 composition to produce vibration displacement,
Thus driving the vibrating diaphragm 3 being attached thereto, vibrating diaphragm 3 is driven produces vibration, drives air vibration about to produce acoustical signal
And sent sound by the outlet sound mouth 9 being placed in electromagnetic shielding shell 7 front end, complete by electric energy to magnetic energy again to mechanical energy finally to acoustic energy
Transduction efficiency.
The present invention, on the premise of ensureing that sound quality is constant, utilizes the quality driving magnet mechanism self, as
A part for sounding vibrating diaphragm in moving-iron microphone in bone conduction type sonifer and loudspeaker arrangement, instead of traditional having
The microphone of identical similar application needs on vibrating diaphragm the weightening finish module individually added, greatly simplify the structure of product；
Product structure after improvement based on the present invention, in the manufacturing process of relevant vibrating diaphragm, it is not necessary to re-use the weightening finish of extra interpolation
Module, simplifies its production technology, improves the manufacturability of product, reduces its production cost；Additionally, driving in the present invention
Dynamic magnet mechanism also can select to be placed in described vibrating diaphragm according to the different size of dynamic ferrum microphone product and frequency response demand
Any of which side in the cavity of both sides, breaches traditional identical similar microphone product and carries because its labyrinth limits
The mechanical dimension come limits, and mechanical dimension is more flexible and changeable, the possibility that significant increase develops to miniature and superminiature direction
Property；Meanwhile, the flexible and changeable of mechanical dimension the most more enriches the moving-iron type being correlated with for bone conduction type sonifer and loudspeaker arrangement
The frequency response of microphone selects, and has widened its range of application, has enhanced the market competitiveness of Related product.
Above the purpose of the present invention, technical scheme and beneficial effect are further described, it should be understood that
It is to the foregoing is only presently preferred embodiments of the present invention, is not limited to the present invention, all spirit in the present invention and former
Within then, any modification, equivalent substitution and improvement etc. done, should be included within the scope of the present invention.
