【Specific embodiment】
In order that the technical scheme and technique effect of this patent are clearer, with reference to the accompanying drawings and examples to this patent
Specific embodiment be described in detail.
Embodiment one：
Such as Fig. 1, the electronic musical instrument of can automatically switch earphone or loudspeaker output audio in the present embodiment, including earphone,
Loudspeaker, earphone state detection module, earphone position detection module and main control module.
Electronic musical instrument is provided with earphone jack and earphone rest area, and earphone can be electrically connected with earphone jack, and earphone can be put in
In earphone rest area, earphone rest area can be the positions such as hook or groove or platform.
Main control module is connected with loudspeaker, for exports audio signal.
Whether earphone state detection module, electrically connect with earphone jack for test earphone and export testing result to master
Control module, its input connection earphone jack, its output end connection main control module.Such as Fig. 2, earphone state detection module can be adopted
Use circuit of the prior art, such as when earphone is inserted in earphone jack, detect the level of earphone jack for low level, and
When earphone is not in earphone jack, the level for detecting earphone jack is high level.
Whether earphone position detection module, export in earphone rest area and by testing result and give master control mould for test earphone
Block, its output end connection main control module.Detection can be using infrared sensor or gravity sensor or ultrasonic sensor inspection
