Abstract
The utility model discloses a hand-operated charging type microphone comprising a holding cylinder and a microphone. The holding cylinder is internally provided with a battery and is also provided with a horizontally placed I-shaped groove. Two side grooves of the I-shaped groove are respectively provided with a piezoelectric thin film. A middle groove of the I-shaped groove is internally installed with a swinging block in a movable way. The holding cylinder is also provided with a super capacitor. The piezoelectric thin film is electrically connected with the super capacitor. The hand-operated charging type microphone can charge a microphone in emergency, the immediate replacement of the battery is not needed, and the use of the microphone is greatly facilitated.
Description
Technical field
The utility model relates to the microphone field, is specially a kind of hand chargeable microphone.
Background technology
Microphone is a kind of stereo set commonly used, is used for the sound that the people sends is amplified.Microphone divides two kinds of cable microphone and wireless microphones, and wireless microphone is by its inner powered battery.In prior art, wireless microphone uses the problem that dead battery often occurs, needs to change battery and just can continue to use, and wastes time and energy.
The utility model content
The purpose of this utility model is to provide a kind of hand chargeable microphone, need change the problem of battery to solve prior art wireless microphone dead battery.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
A kind of hand chargeable microphone, include and hold cylinder, and the spherical microphone that connects a top of being in one's hands, hold and be provided with battery in cylinder, it is characterized in that: described holding also is provided with horizontal I-groove in cylinder, be respectively arranged with piezoelectric membrane in I-groove two side channels, be movably installed with swinging block in the I-groove medial launder, described swinging block two ends are set to respectively cambered surface, hold also to be provided with super capacitor in cylinder, and described piezoelectric membrane is electrically connected to super capacitor by wire respectively.
Described a kind of hand chargeable microphone is characterized in that: the described voltage amplification chip that also is provided with in cylinder between access super capacitor and piezoelectric membrane of holding.
The utility model only need shake microphone when dead battery, make the piezoelectric membrane on swinging block reciprocating extrusion both sides, produce electric energy by piezoelectric membrane, then charge to battery by super capacitor, can charge to microphone when emergent, need not change immediately battery, greatly facilitate the use of microphone.
Description of drawings
Fig. 1 is the utility model structural representation.
