Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a novel plasma loudspeaker. Background Art

[0002] A plasma speaker is a device that uses plasma to generate sound. Its principle is to generate sound waves through electric field changes and air oscillations. There are two common ways to realize plasma speakers: 1. Corona discharge: The corona discharge generated at the high-voltage tip of the Tesla coil forms plasma oscillations, thereby generating sound. 2. Arc type: Using a high-voltage package to boost the voltage, the high voltage generated at both ends of the secondary coil generates an arc, and the sound is generated by controlling the electric field changes and the air oscillations of the plasma.

[0003] The existing technology usually exposes the electrodes to the air, which is easily affected by airflow and affects the arc running, resulting in sound distortion. The appearance is not designed for acoustic structure, so the sound is small and the music reproduction is poor. In addition, a manual switch device is used to achieve the purpose of turning the device on and off, and a continuous working mode with uninterrupted output is adopted. As long as the device is in standby working state, it must be in an arc or corona breakdown state even if there is no sound source input to achieve the purpose of standby and being available at any time. This makes the device inefficient and energy is wasted. In the standby state, the device does not play music, but there is noise from the discharge background noise of the arc or corona itself, which affects the user experience. In addition, the device generates high heat when working, and there is no corresponding safety protection, nor is there a sound and light combination feature. Utility Model Content

The discharge electrode component includes a first conductor and a second conductor. The length of the first conductor is greater than the length of the second conductor. The second conductor guides the generated arc to rise with the hot air flow and stabilize at the first conductor. The first conductor and the second conductor are wired to the power driving circuit board and connected to the input end of the audio Bluetooth chip.
