Skin surface attached Bluetooth speaker

Technical drawing and specification. Skin surface applied Bluetooth speaker. The idea is to have a thin, flat speaker/device that can be placed directly on the skin. A sound emitting speaker/device should have Bluetooth connectivity and also wire connectivity. Should be small, flat and the size of a medication patch or large cardiac monitor patch. There needs to be some system allowing “gluing” or sticking it to the skin surface. It is a multiple use device. Design may use some separate disposable “gluing” patch or disposable membrane (or some other system) to hold it in place. Its skin contact surface should be easy to clean. The device diameter: approx. 4 -6 cm. The project should include parts sourcing directions and possibly manufacturer.
