Audio Circuit Board

Technological innovation

The pure listening technology is to change the sound field of the traditional speaker, the vibration mode of the diaphragm, the standing wave, the air in the box, the inverted structure, etc., so that when people listen to the sound in the near field, they can get a sound without sound coloration, without multiple modulations. An innovative technology with natural and clear sound and good restoration degree, it adopts the following methods:

1. Systematic design

2. No cavity structure

3. SQ speaker technology

4. Parametric equalization amplifier

Audio Circuit Board Features

1. Active speakers: The so-called active speakers can simply be understood as speakers that require power input.

2. Antimagnetic speaker: Since the speaker needs to be placed next to the computer monitor, it has special antimagnetic requirements.

3. Near sound field: The so-called near sound field speaker means that it is very close to the listener when it is playing, generally less than one meter. And semi-free means that it has looser requirements on the position and posture of the listener.

4. Low power: Multimedia speakers are low-power systems, generally only tens of watts of power, such as HI-FI or home theater, where hundreds of watts do not exist, which requires the design of its power amplifier circuit to be as small as possible. Under the power, there must be good sound quality performance, which is also different from home audio.

5. Four field effect high-power push tubes are used, with small signal distortion and large power output.

6. Two filter capacitors to ensure sound quality, safe and reliable

7. All-round protection measures: boot delay; instant shutdown; short circuit, overload protection; output midpoint offset; speaker circuit protection, reliable operation, perfect protection circuit
