Problems solved by technology
For the convenience of users, the earphones can adapt to various audio interfaces, and audio switching devices are usually designed to realize the switching between various audio interfaces, but the existing audio switching devices only realize the switching of audio signals , the function is very single, which cannot meet other needs of users. For example, when some users use headphones, two people often wear one earplug on the headset to listen to music, but the volume cannot be adjusted according to each person's wishes, only two can be adjusted at the same time. The volume of one earplug is difficult to meet the needs of two people at the same time

An audio switching device with a volume control function comprises a first audio interface and a second audio interface; the first audio interface and the second audio interface respectively comprise a left auditory canal audio pin and a right auditory canal audio pin; and the left auditory canal audio pin of the first audio interface is connected with the left auditory canal audio pin of the second audio frequency interface by a first variable resistor, and the right auditory canal audio pin of the first audio interface is connected with the right auditory canal audio pin of the second audio interface by a second variable resistor. The audio switching device can respectively adjust the volume of two earplugs on an earphone which is connected with the device by the variable resistors, which is very convenient.
Description
technical field [0001] The invention relates to an audio switching device. Background technique [0002] At present, earphones are widely used in various audio devices, such as mobile phones, MP3 players, walkmans, etc., and there are more and more types of audio interfaces for earphones, such as traditional 2.5mm / 3.5mm audio interfaces, miniUSB audio interfaces, etc. For the convenience of users, the earphones can be adapted to various audio interfaces, and audio switching devices are usually designed to realize the switching between various audio interfaces, but the existing audio switching devices only realize the switching of audio signals , the function is very single, which cannot meet other needs of users. For example, when some users use headphones, two people often wear one earplug on the headset to listen to music, but the volume cannot be adjusted according to each person's wishes, only two can be adjusted at the same time. It is difficult to meet the needs of tw...
