Description

Technical Field

[0001] The utility model relates to the technical field of circuits, and particularly relates to a control circuit of a head-mounted earphone with separately adjustable dual audio sources. Background Art

[0002] Earphones (including Earphones, Headphones, Head-sets, Earpieces) are a pair of conversion units that receive electrical signals sent from a media player or receiver and convert them into audible sound waves using speakers close to the ears. Earphones can be separated from the media player and are connected only by a plug, allowing users to listen to the audio alone without disturbing others. They can also block out ambient noise, which is very helpful for people using them in noisy environments such as recording studios, bars, during travel, or while exercising. Earphones were originally used for telephones and radios, but with the popularity of portable electronic devices, they are now widely used with mobile phones, walkmans, radios, portable video games, and digital audio players, etc.

[0003] Among them, head-mounted earphones are widely used in the gaming industry. Currently, the head-mounted earphones in the existing gaming industry are generally wired earphones that can only adjust the overall volume, and cannot separately adjust the sound volumes of multiple audio sources. For example, in a team game, generally, the in-game sound is required to be relatively high, and the voice chat sound in the team channel is required to be relatively low. However, the existing head-mounted earphones in the gaming industry cannot separately adjust the sound volumes of various audio sources, resulting in the situation where the voice chat sound often overwhelms the in-game sound, affecting the in-game operations. For users, this is a very poor gaming experience. Summary of the Utility Model
