Abstract

Wireless-enabled loudspeaker includes a wooden capacitive touch user interface. The loudspeaker may comprise at least one electroacoustic transducer, a processor in communication with the at least one electroacoustic transducer, and a wooden exterior surface comprising a capacitive touch user interface that allows a user to control operation of the loudspeaker. The wooden exterior surface acts a dielectric for the capacitive touch user interface. The loudspeaker may comprise a wireless transceiver circuit for receiving and transmitting wireless communication signals via a wireless network. The wireless transceiver circuit may receive wirelessly audio content from streaming audio content servers that are connected to the Internet. The capacitive touch user interface comprises a plurality of user control icons etched in the wooden exterior surface, and a plurality of capacitive sense electrodes located under the wooden exterior surface.

Claims
