A state-of-the-art Piezo-Transducer-Vibrator suitable for a wristwatch has been developed based on a "Customer Comprehension" program: To look at the product from the customer point of view and try to satisfy those needs simultaneously using computer simulation leading to a reliable design in a shorter cycle time. This device is a miniature integrated compact form of both audio and silent alerts which uses less than 8 mA current; desirable to be used in equipments with very small power...
Show moreA state-of-the-art Piezo-Transducer-Vibrator suitable for a wristwatch has been developed based on a "Customer Comprehension" program: To look at the product from the customer point of view and try to satisfy those needs simultaneously using computer simulation leading to a reliable design in a shorter cycle time. This device is a miniature integrated compact form of both audio and silent alerts which uses less than 8 mA current; desirable to be used in equipments with very small power sources. A new ergonomic study was conducted in comprehending the minimum acceptable shake and frequency on human wrist. The complete Piezo-bender structure, its driving format, and its vibration has been modeled accurately to obtain an optimum geometry design for the best possible shake, satisfying all constraints.
