Abstract: Provided are a terminal and a control method of multi-path power supplying. The terminal includes: a battery module having power-supplying paths, power-supplying management modules in one-to-one correspondence with the power-supplying paths and a power supply control module. Each power-supplying path is connected to a power-supplying management module, a first end of each power-supplying management module is connected to a corresponding power-supplying path, a second end is connected to the power supply control module, a third end is connected to at least one function module. The battery module supplies power to at least one function module through multiple independent power-supplying paths. The power supply control module is configured to send a power-supplying control instruction to each power-supplying management module based on a power-supplying demand; Each power-supplying management module is configured to control power supplying of a power-supplying path managed by the power-supplying management module according to the power-supplying control instruction.

Abstract: An impedance matching method for an electret microphone is provided. In some embodiments, the impedance matching method includes collecting a bias voltage between a source and a drain of a field effect transistor built in the electret microphone; determining whether the bias voltage is within a preset bias voltage threshold range; and if it is detected that the bias voltage is not within the preset bias voltage threshold range, sending a corresponding control signal to adjust load bias impedance so that the bias voltage is within the preset voltage threshold. An impedance matching apparatus for an electret microphone and a communication device are also provided.
