摘要： A piezoelectric device is provided with a sound source IC, an amplifier for amplifying a sound source from the sound source IC, a piezoelectric speaker for generating sound based on a drive signal from amplifier, an MPU for performing a predetermined control process on the drive signal, a memory for storing temperature dependency information about the piezoelectric constant (d14) and Young's modulus E of the piezoelectric speaker, and a temperature sensor for detecting an ambient temperature. MPU has correcting unit, compares a detected result of the temperature sensor with the temperature dependency information, and performs temperature correction on the drive signal serving as an acoustic signal based on a compared result. The piezoelectric speaker outputs the acoustic signal temperature-corrected by correcting unit. Thus, it becomes possible to realize various piezoelectric devices, such as a piezoelectric speaker system, capable of preventing various input information from fluctuating even when there is a change in usage environmental temperature.

The touch panel has a piezoelectric sheet of poly-L-lactic acid having a predetermined stretching axial direction, electrodes that are opposed to each other and formed on the piezoelectric sheet do not cover the entire surface of the piezoelectric sheet and are formed so that they are discretely distributed in plural positions. The piezoelectric sheet is brought into the condition that tension is imparted in directions not coincident with the stretching axial direction.

摘要： An electronic device with pressing input function has a substantially rectangular parallelepiped-shaped housing. A display panel with pressure sensor and an arithmetic circuit module are disposed in the housing. The display panel with pressure sensor is composed of a pressure sensor and a display panel. In the display panel, a front polarizing plate is disposed on a front face of a liquid crystal panel. In the pressure sensor, electrodes are formed on both respective flat plate faces of a piezoelectric film having birefringence. The pressure sensor is disposed between the liquid crystal panel and the front polarizing plate of the display panel, and a uniaxial drawing direction of the piezoelectric film is parallel to a polarizing direction of the front polarizing plate.
