Description
Technical field
The utility model relates to acoustic equipment, more specifically, relates to the motor for acoustic equipment.
Background technology
Various types of microphones and receiver (transducer) have used a lot of years.In these equipment, different electric components is accommodated in shell or assembly together.For example, receiver generally comprises coil, bobbin (bobbin), lamination and other elements, and these elements are all contained in receiver shell.The acoustic equipment of other types can comprise the element of other types.Motor generally comprises coil, yoke or lamination and armature, and these elements have formed magnetic circuit jointly.
Can in the multiple application such as such as hearing aids, use transducer.Also can in such as other application such as personal computer or cell phone, use these equipment.
As mentioned above, receiver has armature.Armature is movable element, and in the time of magnetic field that electric current changes in receiver, armature just moves.
Receiver bears multiple external force.For example, if adopt receiver in personal computer or cell phone, this equipment may drop.The impulsive force producing that drops like this may be damaged the element of receiver or the element of receiver is offset.
