Description
Technical field
The present invention relates to small and special electric machine field, and in particular to one kind vibration small and special electric machine.
Background technology
Small and special electric machine, the miniature specific type of electric machine of full name, abbreviation micro machine refers to smaller diameter or rated power or with special
The small and special electric machine of performance, specific use.Small and special electric machine is usually used in control system, realizes detection, the solution of dynamoelectric signal or energy
Calculate, amplification, perform or conversion etc. function, or for gearing load, also can as equipment AC and DC power supply.
Existing vibration small and special electric machine is widely used in electronic product, but is due to that some electronic products generally can all be added
Vibration function, but existing vibration small and special electric machine is all generally single vibrations, and sound can not be sent, it is impossible to meet part
Equipment needs the demand of vibration and sounding simultaneously.
The content of the invention
In view of the above-mentioned problems, a kind of the present invention is intended to provide micro- special electricity of vibration that can be shaken and send certain melody sound
Machine.
To realize the technical purpose, the solution of the present invention is：One kind vibration small and special electric machine, including balance weight, housing, magnetic
Iron, rotating shaft, iron core, commutator, the housing set cored, and the iron core is wrapped with the middle part of enamel-covered wire, the iron core and passed through
Wear and be equipped with rotating shaft, described rotating shaft one end is fixedly connected with balance weight, the rotating shaft other end and is fixedly installed commutator, institute
State commutator to be connected with brush contact in housing, variable resistance, the rotating shaft and housing two are provided between the commutator and iron core
End is respectively arranged with bearing；
The balance weight is semi-cylindrical type eccentric structure, and the rotating shaft tail end is also associated with sounding projection, the housing
Side is cased with sounding chamber, and the sounding intracavitary side is provided with shell fragment, and the shell fragment is corresponding with projection position.
Beneficial effects of the present invention, the application is combined using the balance weight of semi-cylindrical type eccentric structure with motor, is realized
Vibration function, in combination with the rotating function of machine shaft, in rotating shaft, another is provided with sounding projection, when axis of rotation is,
Sounding projection can be contacted with the shell fragment of sounding intracavitary, send the sound of certain graceful melody, and the structural volume is small, and cost is low,
Needs can be met while the equipment of vibration and sounding is used.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
The present invention is described in further details with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, specific embodiment of the present invention is a kind of vibration small and special electric machine, including balance weight 10, housing
1st, magnet, rotating shaft 2, iron core 4, commutator 7, the housing 1 set cored 4, and the iron core 4 is wrapped with enamel-covered wire 5, described
The middle part of iron core 4 is provided through rotating shaft 2, and described one end of rotating shaft 2 is fixedly connected with balance weight 10, the other end of rotating shaft 2 solid
Surely commutator 7 is provided with, the commutator 7 contacts connection with brush 9 in housing 1, is set between the commutator 7 and iron core 4
There is variable resistance 6, the rotating shaft 2 is respectively arranged with bearing 8 with the two ends of housing 1；
The balance weight 10 is semi-cylindrical type eccentric structure, and the tail end of rotating shaft 2 is also associated with sounding projection 11, described
The side of housing 1 is cased with sounding chamber 12, and the inner side of sounding chamber 12 is provided with shell fragment 13, and the shell fragment 13 is relative with the position of projection 11
Should.
The application is combined using the balance weight of semi-cylindrical type eccentric structure with motor, realizes vibration function, in combination with
The rotating function of machine shaft, in rotating shaft, another is provided with sounding projection, and when axis of rotation is, sounding projection can be with sounding
The shell fragment contact of intracavitary, sends sound that is brief but having certain graceful melody, and the structural volume is small, and cost is low, can meet
Need while the equipment of vibration and sounding is used.
Described above, only presently preferred embodiments of the present invention is not intended to limit the invention, every skill according to the present invention
Any trickle amendment, equivalent substitution and improvement that art is substantially made to above example, should be included in technical solution of the present invention
Protection domain within.
