Abstract

The invention discloses a flat panel speaker and a vehicle including the same. The flat panel speaker includes: a substrate; a plurality of horizontal frames disposed on the substrate and dividing the substrate into a plurality of rows; a plurality of vertical frames disposed on the substrate and dividing each of the plurality of rows into a plurality of columns; a plurality of piezoelectric elements disposed on a side surface of each of the plurality of vertical frames and configured to contract and expand according to a voltage signal; a plurality of electrodes configured to apply a voltage signal to the piezoelectric element; and a controller configured to control a voltage signal applied to the plurality of electrodes.

Description

Technical field [0001] The present invention relates to a flat speaker and a vehicle comprising a flat speaker. Background [0002] Since the voice coil type speakers set in the vehicle generate sound waves by moving the diaphragm, when the output has a loud pressure level or low-frequency sound, the vibration of the diaphragm is very large and generates noise. [0003] In addition, since the voice coil speaker essentially requires a magnetic field for moving the voice coil, and requires a baffle and housing, the voice coil speaker occupies a larger volume in the limited space of the vehicle. Contents of the Invention [0004] The present invention relates to a flat speaker comprising a piezoelectric element and a vehicle comprising the flat panel speaker. Particular embodiments relate to a flat speaker comprising a piezoelectric element and a vehicle comprising the flat panel speaker. [0005] Embodiments of the present invention provides a flat speaker and a vehicle comprisin...
