摘要： In a terminal device in this application, a device housing includes an installation space and a first inner cavity that are isolated from each other. A speaker is installed in the installation space. The speaker includes a speaker shell provided with a sound hole and a second inner cavity, and a vibrating piece, a signal amplifier, and a speaker body that are disposed in the second inner cavity. The first inner cavity and the second inner cavity are isolated from each other. A circuit board is installed in the first inner cavity. The circuit board is provided with a sound signal processing module and a vibration sound wave generation device. The vibration sound wave generation device is connected to the sound signal processing module. The vibration sound wave generation device converts a sound signal from the sound signal processing module into a vibration signal.
