The invention relates to a home theater audio system, which includes earphones and a volume controller; the volume controller includes a micro-processing chip, a decibel tester and a volume adjustment drive circuit, the output end of the decibel tester is connected to the input end of the micro-processing chip, and the micro-processing The output end of the chip is connected to the control end of the volume adjustment drive circuit; the microprocessing chip includes a storage unit, a determination unit, a volume calculation unit and a volume control unit, and the maximum volume value and the reasonable volume value are pre-stored in the storage unit. The micro-control chip of the present invention pre-stores the maximum volume value and the reasonable volume value, detects the actual volume in use at intervals, compares it with the maximum volume value and the reasonable volume value, and adjusts the volume reasonably according to the comparison result. The volume effect of the invention is good, the volume can always be controlled within a reasonable range, preventing audiovisual impact due to too low volume, or hearing damage caused by excessive volume, and comprehensively protecting the hearing health of users.
Description
Technical field [0001] The present invention belongs to the field of smart home appliances, which involves a home theater, in particular to a sound effect system for home theater. Background technique [0002] With the continuous improvement of people's living standards, more and more smart home appliances are developed, produced, and put into use. Especially the home theater, you can enjoy the fun of movies from home, so more and more people are passionate about studying home theater. [0003] At present, the voice of the home theater usually plays with audio, and the sound playback of the audio will inevitably interfere with the next neighbor, unless the sound of the sound is particularly good, otherwise it will inevitably affect others. In order to inevitably interfere, the user may use headphones, but long time with headphones movies or TV sounds, if the sound of the headphones is small, it may not be able to observe the sound, and it is usually a movie or TV. The volume is t...
