TERMINAL APPARATUS Russian patent published in 2022 - IPC H04R9/06 

FIELD: acoustics.

SUBSTANCE: terminal apparatus for audio reproduction, consisting of: a body of the apparatus, wherein the body comprises an installation space and a first internal cavity, isolated from each other; a speaker, wherein the speaker is installed in the installation space, and the speaker comprises a speaker body equipped with a sound hole and a second internal cavity, as well as a vibration element, a signal amplifier, and a speaker body, located in the second inner cavity. The first inner cavity is isolated from the second inner cavity. A printed circuit board is installed in the first internal cavity; the printed circuit board is equipped with an audio signal processing module and a vibration sound wave generation apparatus; the vibration sound wave generation apparatus is connected to the audio signal processing module; the vibration sound wave generation apparatus converts the audio signal from the audio signal processing module into a vibration signal; the vibration element vibrates due to the effect of the vibration signal and generates an electrical signal; the signal amplifier is connected to the vibration element to amplify the electrical signal, and the speaker body is connected to the signal amplifier to reproduce sound based on the amplified electrical signal through the sound hole.

EFFECT: higher sound quality.
