Abstract

The invention discloses sound source equipment. The sound source equipment comprises an earphone tolerance degree acquisition module; and when the sound source equipment is connected with an earphone, the sound source equipment acquires earphone tolerance degree and controls the output of the volume of the earphone according to the acquired earphone tolerance degree. An earphone output control method for the sound source equipment comprises the following steps of: acquiring the earphone tolerance degree; and controlling the output of the volume of the earphone according to the acquired earphone tolerance degree. By the method, the sound source equipment and the earphone can be unified in both interface and function; and the same sound source equipment can adapt to the earphones of different performance to support each other in function, reasonably extend, support more choices and keep the best output. The earphone and the sound source equipment can adapt to each other in the volume output without burning down the earphone due to the high output power.

Description

technical field [0001] The invention relates to a sound source device and a control method. Background technique [0002] Now, along with the development of technology, more and more sound source equipments such as MP3, DVD player, TV set, radio, telephone, mobile phone etc. appear in people's life, add fun to people's life. When using these devices, there are generally two ways to output audio, one is the speaker, and the other is the earphone. When using earphones as audio output devices, earphones are generally divided into wired earphones and wireless earphones; in addition, according to the channel, earphones are divided into mono earphones, binaural earphones (also known as stereo earphones), and Multi-channel headphones (also known as surround sound headphones). Judging from the earphones sold in the market, the earphones produced by different manufacturers are all different, and the interface standards are not particularly uniform; especially for high-end earphone ...
