Abstract: A terminal device includes a housing, a microphone, a sound guide support, a circuit board, and a vibration assembly. The housing is provided with a sound collecting hole, the sound guide support and the circuit board are disposed in the housing, the sound guide support and the circuit board form a first cavity, the vibration assembly is disposed between the sound guide support and the circuit board and separates the first cavity into a sound guide channel and a second cavity, and the microphone and the sound collecting hole are respectively disposed at both ends of the sound guide channel.

Abstract: An electronic device is provided. The electronic device includes a device body, a first sound-emitting component, and a second sound-emitting component. the first sound-emitting component and the second sound-emitting component are both disposed in the device body. The first sound-emitting component emits a first ultrasonic wave The second sound-emitting component emits a second ultrasonic wave. A frequency of the first ultrasonic wave is different from that of the second ultrasonic wave. A first sound guide channel and a second sound guide channel are disposed in the device body. A first sound guide hole and a second sound guide hole are disposed at an outer surface of the device body. The first sound-emitting component is connected to the first sound guide hole through the first sound guide channel. The second sound-emitting component is connected to the second sound guide hole through the second sound guide channel.
