Abstract
The present disclosure discloses an electro-acoustic conversion device and a terminal. The electro-acoustic conversion device includes a housing, an electro-acoustic component, and a vibration element. The housing is provided with a sound chamber and a sound outlet communicating with the sound chamber. The electro-acoustic component is arranged in the sound chamber. The vibration element is fixed to the housing and configured to generate sound waves to atomize liquid in the sound chamber, so that the atomized liquid is discharged outside the sound chamber through the sound outlet.
