Abstract
The utility model discloses a vibrating small and special electric motor, casing are provided with the iron core, run through being provided with the pivot in the middle part of the iron core, pivot one end fixedly connected with balancing piece, and the fixed commutator that is provided with on the pivot other end, the commutator is connected with the interior brush contact of casing, be provided with varistor between commutator and the iron core, the pivot is provided with the bearing respectively with the casing both ends, the balancing piece is the eccentric structure of semi -cylindrical type, the pivot tail end still is connected with vocal projection, casing one side cover has vocal chamber, sound production intracavity side is provided with the shell fragment. The balancing piece and the motor combination of semi -cylindrical type off -centre structure are adopted in this application, realize the vibrations function, combine motor shaft's rotation function simultaneously, and another is provided with vocal projection in the pivot, work as the pivot rotation to be, vocal projection can contact with the shell fragment of vocal intracavity, sends the sound of certain graceful melody, and this volume is little, and is with low costs, can satisfy the demand vibration simultaneously and vocal disposition of equipment.
Description
Technical field
This utility model is related to small and special electric machine field and in particular to a kind of vibrate 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, refer to that diameter is less rated power or have special
Performance, the small and special electric machine of specific use.Small and special electric machine is usually used in control system, realizes detection, the solution of dynamoelectric signal or energy
The function such as calculate, amplify, execute or change, or for gearing load, also can be used as the AC and DC power supply of equipment.
Existing vibration small and special electric machine is widely used in electronic product, but because some electronic products generally all can add
Vibration function, but existing vibration small and special electric machine is generally all single vibrations, and sound cannot be sent it is impossible to meet part
Equipment needs to vibrate the demand with sounding simultaneously.
Utility model content
For the problems referred to above, this utility model aim to provide a kind of can shake and send certain melody sound vibration micro-
Special motor.
For realizing this technical purpose, scheme of the present utility model is：A kind of vibration small and special electric machine, including balance weight, housing,
Magnet, rotating shaft, iron core, commutator, described housing setting is cored, and described iron core is wrapped with enamel-covered wire, in the middle part of described iron core
It is provided through rotating shaft, described rotating shaft one end is fixedly connected with balance weight, the described rotating shaft other end is fixedly installed commutator,
Described commutator is connected with brush contact in housing, is provided with variable resistance between described commutator and iron core, described rotating shaft and housing
Two ends are respectively arranged with bearing；
Described balance weight is semi-cylindrical type eccentric structure, and described rotating shaft tail end is also associated with sounding projection, described housing
Side is cased with sounding chamber, and described sounding intracavity side is provided with shell fragment, and described shell fragment is corresponding with projection position.
The beneficial effects of the utility model, the application adopts the balance weight of semi-cylindrical type eccentric structure to be combined with motor,
Realize vibration function, in combination with the rotating function of machine shaft, another is provided with sounding projection in rotating shaft, works as axis of rotation
It is that sounding projection can be contacted with the shell fragment of sounding intracavity, sends the sound of necessarily graceful melody, this structural volume is little, cost
Low, needs can be met and vibrate the equipment use with sounding simultaneously.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
With specific embodiment, this utility model is described in further details below in conjunction with the accompanying drawings.
As shown in figure 1, specific embodiment described in the utility model is a kind of vibration small and special electric machine, including balance weight 10,
Housing 1, Magnet, rotating shaft 2, iron core 4, commutator 7, described housing 1 arranges cored 4, and described iron core 4 is wrapped with enamel-covered wire 5,
It is provided through rotating shaft 2, described rotating shaft 2 one end is fixedly connected with balance weight 10, described rotating shaft 2 other end in the middle part of described iron core 4
On be fixedly installed commutator 7, described commutator 7 contacts connection with brush 9 in housing 1, between described commutator 7 and iron core 4
It is provided with variable resistance 6, described rotating shaft 2 is respectively arranged with bearing 8 with housing 1 two ends；
Described balance weight 10 is semi-cylindrical type eccentric structure, and described rotating shaft 2 tail end is also associated with sounding projection 11, described
Housing 1 side is cased with sounding chamber 12, is provided with shell fragment 13 inside described sounding chamber 12, and described shell fragment 13 is relative with projection 11 position
Should.
The application adopts the balance weight of semi-cylindrical type eccentric structure to be combined 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
But the shell fragment contact of intracavity, sends sound that is brief having necessarily graceful melody, and this structural volume is little, and low cost can meet
Need to vibrate the equipment use with sounding simultaneously.
The above, preferred embodiment only of the present utility model, not in order to limit this utility model, every foundation is originally
Any trickle amendment, equivalent and improvement that the technical spirit of utility model is made to above example, should be included in this
Within the protection domain of utility model technical scheme.
