Terminal device

A terminal device, comprising:

• a device housing, wherein the device housing comprises an installation space and a first inner cavity that are isolated from each other;
• a speaker, wherein the speaker is installed in the installation space, and the speaker comprises 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, wherein the first inner cavity and the second inner cavity are isolated from each other;
• and
• a circuit board, wherein the 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, the vibration piece vibrates under the action of the vibration signal and generates an electrical signal, the signal amplifier is connected to the vibration piece and amplifies the electrical signal, and the speaker body is connected to the signal amplifier and produces sound based on the amplified electrical signal through the sound hole.
