Abstract: The wireless headset includes a main control module. The main control module includes a rigid-flexible circuit board, a first substrate, a first support member, and a plurality of chips. The rigid-flexible circuit board includes a rigid board portion and a first flexible board portion and a second flexible board portion that are connected to the rigid board portion. The rigid board portion is located in the earbud portion. The first flexible board portion is located in the earbud portion and has one end connected to the rigid board portion. One end of the second flexible board portion is connected to the rigid board portion and the other end thereof extends to the ear handle portion. A plurality of layers of components are stacked on the rigid board portion of the wireless headset, so that component integration degree is high.

Abstract: An anti-short-circuit detection apparatus includes a probe, a detection resistor, a switching circuit, and a detection circuit. The probe is disposed between a power port and a ground port. A first terminal of the detection resistor is electrically coupled to a power circuit of the user terminal, and a second terminal of the detection resistor is electrically coupled to the probe. The switching circuit is electrically coupled to the first terminal of the detection resistor and a processor of the user terminal and is configured to perform switching to be grounded or ungrounded under the control of the processor. The detection circuit is electrically coupled to two terminals of the detection resistor and the processor, and is configured to trigger the processor to control the user terminal to issue a short-circuit warning or turn off the power circuit when the short-circuit current is not zero.
