Abstract
The utility model discloses a charging type microphone device. The device comprises a holding barrel, the holding barrel is internally provided with a battery, the bottom of the holding barrel is connected with a rubber sleeve, the rubber sleeve is internally provided with a piezoelectric block, the piezoelectric block is connected with a voltage stabilizing circuit in the holding barrel, the voltage stabilizing circuit is connected to a super capacitor through a lead, and the super capacitor is connected with the battery through a lead. When electricity of the battery is used up, the charging type microphone device can charge by itself, and the battery needn't be replaced immediately, greatly facilitating use of the microphone.
Description
Technical field
The utility model relates to the microphone field, is specially a kind of rechargeable microphone device.
Background technology
Microphone is a kind of stereo set commonly used, divides two kinds of cable microphone and wireless microphones, and wireless microphone is by its inner powered battery.When dead battery appears in wireless microphone in the prior art, need to change battery and just can continue to use, very inconvenient.
The utility model content
The purpose of this utility model provides a kind of rechargeable microphone device, to solve the awkward problem of prior art wireless microphone.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of rechargeable microphone device, include and hold tube, and the spherical microphone that connects a top of being in one's hands, hold and be provided with battery in the tube, it is characterized in that: the described tube bottom of holding is connected with rubber sleeve, and rubber sleeve inner close fitting rubber sleeve sidewall is provided with piezoelectric blocks, be positioned at and hold tube and be provided with voltage stabilizing circuit, super capacitor, described piezoelectric blocks is connected with the voltage stabilizing circuit input by lead, and circuit output end of pressure-stabilizing inserts super capacitor by lead, and described super capacitor is connected with battery by lead.
Described a kind of rechargeable microphone device is characterized in that: described rubber sleeve outer wall is set to corrugated surface.
The utility model only needs extruding hold the tube bottom rubber sleeve when dead battery, makes that piezoelectric blocks produces voltage in the rubber sleeve, and voltage is sent into the super capacitor storage by voltage stabilizing circuit, by super capacitor to battery charge.The utility model can charge when dead battery voluntarily, need not change battery immediately, greatly facilitates microphone and uses.
Description of drawings
Fig. 1 is the utility model structural representation.
