摘要： The present disclosure provides a hot-swap circuit and a control apparatus. The hot-swap circuit includes: a power input terminal, a power output terminal; a startup module electrically connected to the power input terminal and the power output terminal; a switch module electrically connected to the power input terminal, the power output terminal, and the startup module; a detection module electrically connected to the startup module, the switch module, and the power output terminal. When a surge signal is input at the power input terminal, a voltage value of a first control signal output by the detection module doesn't fall in a voltage value range of a preset first control signal, then the switch module is controlled to be turned off, so as to cut off a power signal input to the power output terminal, reducing probability of circuit damage, and reducing sparking phenomena of hot-swap power interfaces.

摘要： The present application discloses a microphone, including: a housing; at least two sound-pickup members respectively disposed on the housing; a control circuit board disposed in the housing and in electrical connection to the at least two sound-pickup members respectively; and a switch member configured for triggering the control circuit board to select one or more of the sound-pickup members for collecting an external sound source. The present application addresses the shortcoming that it is necessary to change the direction of the microphone according to the needs of the scene, realizes the flexible selection and configuration of multiple sound-pickup members, and enriches the use scene of the operator. Once the recording site is set up, recordings with different requirements can be realized by switching circuit, so as to reduce the movement of recording equipment, which is suitable for recording equipment such as a camera and a camcorder.
