Mobile, integrated device to be worn on the wrist for stimulating the skin for the purpose of transmitting audio signals modulated on ultrasound frequencies via circular integrated, combined, metal / piezoceramic disks by means of contact vibration

摘要

Device for stimulating the skin with audio signals modulated on ultrasound frequencies via piezoceramic disks by means of vibration (Fig. 2), essentially consisting of a shape to be worn on the wrist (Fig. 1-1) in the form of a mobile form (based on the shape of a watch), the underside (aligned to the skin of the user) has two round metal plates (Fig. 1-2) with an internal piezoceramic layer. The discs are made in the form of a round blank, which makes it possible to apply the ultrasonic frequencies by direct contact with the skin of the user by means of vibration. Audio signals are modulated onto this ultrasonic frequency via an integrated audio player. The top has a display (Fig. 3), which shows the current function of the device and can function as a clock at the same time.
