摘要:
A waterproof construction around a miniature buzzer incorporated in an electronic alarm watch depends on a gasket alone. The construction is such that the gasket can secure a resonant plate without any storage of distortion in the resonant plate. This feature makes it possible to provide the electronic alarm watch having a stable performance for acoustic emission.
