Detailed Description

The autonomous tracing acousto-electric conversion and storage device provided by the invention is further described in detail and completely in the following embodiments. The following examples are illustrative only and are not to be construed as limiting the invention.

An acoustoelectric conversion and storage device, as shown in fig. 1 and 2, includes a diaphragm 1, a ring magnet 2, a metal bar, a coil 3, a voltage boosting and stabilizing structure 4, a capacitor and a sound receiving tube 5. The sound receiving cylinder 5 is horn-shaped, the vibrating membrane 1 is positioned at the large opening end of the horn-shaped sound receiving cylinder 5, and the annular magnet 2, the metal rod, the coil 3, the voltage boosting and stabilizing structure 4 and the capacitor are positioned in a cavity enclosed by the sound receiving cylinder 5 and the vibrating membrane 1.

The vibrating diaphragm 1 is conical, the conical bottom surface of the vibrating diaphragm 1 is flush with the large-opening end of the sound receiving tube 5, and the top of the tip end of the vibrating diaphragm 1 is located in a cavity formed by the sound receiving tube 5 and the vibrating diaphragm 1.

The metal rod is a cylindrical long rod, one end of the metal rod is connected with the tip end of the vibrating membrane 1, and the other end of the metal rod is fixedly connected with the coil 3, namely the coil 3 and the metal rod can be driven to move mutually. The ring magnet 2 is annular and sleeved outside the metal rod, and the ring magnet 2 is not in contact with the metal rod, namely, the ring magnet 2 and the metal rod do not influence the movement of each other. Preferably, the ring magnet 2 is sleeved at one end of the metal rod close to the vibrating diaphragm 1, and the ring magnet 2 and the sound receiving tube 5 are relatively fixed. And a coil 3 is sleeved outside one end of the metal rod, which is far away from the vibrating membrane 1. The coil 3 is a conductive coil, the coil 3 is connected with the voltage boosting and stabilizing structure 4 and the capacitor, and the voltage boosting and stabilizing structure 4 and the capacitor are relatively fixed with the sound receiving tube 5.

When the invention works, when noise is transmitted to the conversion and storage device, the sound wave of the noise causes the vibration film 1 to vibrate, the vibration film 1 drives the metal rod connected with the vibration film and the coil 3 to do reciprocating vibration motion, thus, the metal rod with the coil 3 does cutting magnetic induction line motion in the annular magnet 2 to generate induced current. The ring magnet 2 is relatively heavy and is therefore arranged relatively fixed to the sound-absorbing shell 5; the metal rod with the coil 3 is relatively lighter than the annular magnet 2 in weight, is set as a part driven to move, has smaller inertia and smaller resistance, is easier to be driven to move by the vibrating membrane 1, and reduces the energy loss of the vibrating membrane 1. The capacitor is used for storing the electric quantity generated by the kinetic energy of the vibrating membrane 1. The conical diaphragm 1 and the sound-absorbing cylinder 5 have a horn-shaped appearance, which is favorable for absorbing noise. The shape clearance of the sound-absorbing cylinder 5 uses high-quality sound-absorbing materials to reduce noise and is used for absorbing 20-20000HZ noise, and the design device mainly absorbs the noise through environment-friendly high-quality sound-absorbing materials (tree cotton, asbestos and the like). The reverse principle of the horn and the internal circuit with low power consumption ensure the efficient and low-cost operation of the device.

The induced current generated is small, the current is calculated to be about 20-30 milliamperes, so that the generated voltage level is small, and the voltage boosting and stabilizing structure 4 comprises a voltage boosting structure and a voltage stabilizing structure, wherein the voltage boosting structure is used for increasing the induced current and further improving the voltage of the induced current. The current is stabilized in a stable output environment through the voltage stabilizing circuit, specifically, the voltage of the current is stabilized at about 3.3V, and a stable output current is ensured. And finally, the capacitor is used for storage in a storage battery mode, and the purposes of sound-electricity conversion and energy storage are finally achieved.

Therefore, on the basis of storing the kinetic energy in the conversion device, the overall scheme flow of the invention is obtained as shown in fig. 3, the vibration unit (the vibration film 2) absorbs noise, the fluctuation of the noise is converted into the kinetic energy of the vibration unit, then the closed loop is driven to move in a magnetic field, further induction current is generated, the induction current and voltage are increased through the boost module, the current is in a stable output environment through the voltage stabilizing module, and finally the electric energy is stored through the capacitor module. The electric energy stored by the capacitor module can be further collected and stored by an electric storage battery, or can be directly used by a capacitor storage unit.

Finally, it must be said here that: the above embodiments are only used for further detailed description of the technical solutions of the present invention, and should not be understood as limiting the scope of the present invention, and the insubstantial modifications and adaptations made by those skilled in the art according to the above descriptions of the present invention are within the scope of the present invention.
