Title: Surface acoustic wave device
IPC: H03H9/25
Filed: 1992-03-17
Abstract: PURPOSE:To dispense with a sound absorbing agent, and to miniaturize the device by forming a minute notch part for reflecting irregularly an elastic wave toward the side face, along an end edge of the substrate surface side of an end face being orthogonal to a propagation axis of the elastic wave. CONSTITUTION:A shell-like, hemispherical or 1/4 spherical minute notch part 4 is formed along an end edge of the substrate surface side of an end face 3. When the shell-like or hemispherical notch part 4 is formed, as for an elastic wave which is made incident on the end face part 3, in accordance with a rule of reflection, the greater part thereof is reflected to both side faces 5, 6. Also, since its reflection angle is different in accordance with an incident position to the notch part 4, the elastic wave is reflected to the side faces 5, 6 in a state that it is dispersed at various reflection angles. An end face reflected wave which is made incident on these side faces 5, 6 is attenuated, while it is subjected to multipath reflection by a dispersion effect and an interference operation. Thus, the end face reflected wave can be eliminated without applying a sound absorbing agent to the surface of the substrate, and also, a surface area between a transducer 2 and the end face 3 can be made small, and the device can be miniaturized.
