Preferably, micropores are uniformly distributed on the spherical surface of the spherical top of the cathode.

Compared with the prior art, the invention has the following beneficial effects:

in the base: after the top of the guide cathode induces an electric field of a cathode ball top, the electric field is led into electrolyte solution at the lower end, positive ions and negative ions are separated under the action of a graphite anode, the positive ions are concentrated near the guide cathode, the electrolyte solution is atomized by ultrasonic waves generated by an ultrasonic atomizing sheet right below the guide cathode to generate a large number of fog drops with positive electricity, the fog drops move upwards to reach the top of the guide cathode, the electrified fog drops fly to the cathode ball top along the direction of the electric field under the action of the electric field of the cathode ball top, and in the process, the electrified fog drops continuously collide with air molecules to push the air outwards to generate sound waves, and a plurality of holes are uniformly distributed on the cathode ball top to allow the sound waves to pass and spread outwards.

The electrolyte solution is atomized by ultrasonic waves to generate a large number of tiny charged fog drops, the charged fog drops are placed in an electric field, the charged fog drops accelerate towards the direction of the electric field under the action of the electric field force and collide with air molecules, when a large number of continuous charged fog drops are simultaneously oriented and collide with the air molecules, the air molecules are extruded from the collision direction, so that air pressure changes, and the strength of the electric field is controlled by an audio signal, so that the air pressure follows the change of the audio frequency to finally restore an acoustic signal.

In summary, the present invention provides an electroacoustic transducer device, which generates charged particles by ultrasonically atomizing an electrolyte solution and generates sound by controlling the movement of the charged particles through an electric field.

The charged droplets have very small volume and light weight (the diameter can reach 1um), so the sound transient characteristics are very good;

2. because the invention has no vibrating diaphragm structure: the problem of harmonic distortion caused by vibration diaphragm resonance is solved, the manufacturing process is simpler and the cost is lower;

3. the sound radiation of the invention is nondirectional, and can produce an omnidirectional listening effect;

4. the invention can push larger volume of air compared with plasma loudspeaker, thus can produce better low frequency response.
