Patent abstract
A piezo-electric speaker ensures a uniform sound in a broad band and can easily reproduce a signal of large amplitude or sound. A piezo-electric speaker has a piezo-electric member to generate a vibration according to an electric signal applied thereto. A piezo-electric vibration plate converts the vibration to a sound. The piezo-electric vibration plate is positioned closely to the piezo-electric member. The piezo-electric vibration plate is divided into parts of any configuration and is connected to the piezo-electric member.
