Abstract: 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.

Abstract: A pressure detection apparatus includes a substrate, a light conducting layer, a light absorbing layer, and a photosensitive layer that are arranged in order, and further includes a light source. The light source is capable of emitting light of a first frequency, and an emergent surface of the light source faces toward the light conducting layer. The light conducting layer disperses the light of the first frequency. The light absorbing layer includes a container forming a closed space and an absorption liquid filling the container, where the absorption liquid absorbs at least a part of the light of the first frequency, and at least one side surface of the container is an elastic surface. A photosensitive surface of the photosensitive layer faces toward the light absorbing layer, and the photosensitive layer is used to detect the light of the first frequency that passes through the light absorbing layer.
