Audio equipment based on high-voltage ionized air

Abstract

The present invention is an audio equipment and control method based on high-voltage ionized air, and its structure includes a power supply, a Bluetooth module, a modulation module, a drive module, a high-voltage package, electrodes, an MSP430F6638 main control module, a data display device (12864 liquid crystal display), a detection feedback module. Advantages: 1) It directly acts on the air, but the discharge scale is very small. The sounding part of the speaker is only the electrode and the arc. By changing the thickness and length of the arc, the size of the sound can be controlled; 2) The high-pitched part has a good reduction degree and is difficult to distort. 3) Use MSP430F6638 as the main control chip to measure data such as temperature, humidity, and ozone content. The device is more secure; 4) It supports connecting with mobile terminals through Bluetooth communication and playing music wirelessly.

Description

technical field [0001] The invention relates to an audio equipment based on high-voltage ionized air, which belongs to the technical field of audio equipment. Background technique [0002] Ordinary speakers use the vibration of the diaphragm to drive the air to make sound. Since each diaphragm has a different resonance frequency, the amplitude-frequency characteristics of the sound are deteriorated——the component in the audio signal whose frequency is close to the resonance frequency of the diaphragm is the strongest, while the frequency Components away from the resonance frequency will be attenuated, the farther away the more the attenuation will be, and finally it will be completely attenuated. In order to produce sound performance, the resonance problem of the sound must be solved. [0003] Nowadays, there are more and more people who are constantly pursuing bass and high-fidelity effects. Some people have a persistent pursuit of treble effects, but a set of speakers made...
