Wooden or other dielectric capacitive touch interface and loudspeaker having same
Wireless-enabled loudspeaker includes a 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 an exterior surface comprising a capacitive touch user interface that allows a user to control operation of the loudspeaker. The 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 capacitive sense electrodes.
1. A loudspeaker comprising:
an enclosure defined by a base surface, a smooth, topmost surface, and a sidewall extending between the base surface and the smooth topmost surface, wherein:
the enclosure is free-standing when sitting on the base surface; and
the smooth topmost surface of the loudspeaker comprises a dielectric material defining a capacitive touch user interface;
one or more speakers;
a wireless communication circuit inside the enclosure, wherein the wireless communication circuit is for wirelessly receiving an audio stream, wherein the one or more speakers are for playing the audio stream; and
at least one capacitive sense electrode, wherein the at least one capacitive sense electrode forms part of the capacitive touch user interface for the loudspeaker, with the dielectric material of the smooth topmost surface serving as a dielectric layer for the capacitive touch user interface, such that the capacitive touch user interface allows a user of the loudspeaker to control at least one operation of the loudspeaker through touching the smooth topmost surface of the loudspeaker.
2. The loudspeaker of claim 1 , wherein the smooth topmost surface of the enclosure comprises at least one symbol icon aligned with the at least one capacitive sense electrode to indicate to a user of the loudspeaker where to touch the smooth topmost surface of the loudspeaker to control the at least one operation of the loudspeaker.
3. The loudspeaker of claim 2 , wherein a user touching the smooth topmost surface at the at least one symbol icon activates the at least one capacitive sense electrode to control the at least one operation of the loudspeaker.
4. The loudspeaker of claim 3 , wherein a user touching the smooth topmost surface in close proximity to the at least one symbol icon activates the at least one capacitive sense electrode to control the at least one operation of the loudspeaker.
5. The loudspeaker of claim 4 , wherein the at least one symbol icon is associated with:
an LED indicator at the smooth topmost surface; and
an LED driver connected to the LED indicator.
6. The loudspeaker of claim 5 , wherein the LED indicator emits light upon activation of the at least one capacitive sense electrode.
7. The loudspeaker of claim 1 , wherein a mobile device configured to access a web site hosted by a remote server is used by a user to configure or set-up the loudspeaker.
8. The loudspeaker of claim 1 , wherein the loudspeaker is configured to be paired with one or more than one additional loudspeaker to create a surround sound system.
9. The loudspeaker of claim 1 , further comprising a digital audio processor.
10. A system, comprising:
a first loudspeaker; and
a second loudspeaker paired to the first loudspeaker to provide surround sound, wherein the first loudspeaker comprises:
an enclosure defined by a base surface, a smooth, topmost surface, and a sidewall extending between the base surface and the smooth topmost surface, wherein:
the enclosure is free-standing when sitting on the base surface; and
the smooth topmost surface comprises a dielectric material defining a capacitive touch user interface;
one or more speakers;
a wireless communication circuit inside the enclosure, wherein the wireless communication circuit is for wirelessly receiving an audio stream, wherein the one or more speakers are for playing the audio stream; and
at least one capacitive sense electrode, wherein the at least one capacitive sense electrode forms part of the capacitive touch user interface for the first loudspeaker, with the dielectric material of the smooth topmost surface serving as a dielectric layer for the capacitive touch user interface, such that the capacitive touch user interface allows a user to control at least one operation of the first loudspeaker through touching the smooth topmost surface of the first loudspeaker.
11. The system of claim 10 , wherein the smooth topmost surface of the enclosure comprises at least one symbol icon aligned with the at least one capacitive sense electrode to indicate to a user where to touch the smooth topmost surface to control the at least one operation.
12. The system of claim 11 , wherein a user touching the smooth topmost surface at the at least one symbol icon activates the at least one capacitive sense electrode to control the at least one operation.
13. The system of claim 12 , wherein a user touching the smooth topmost surface in close proximity to the at least one symbol icon activates the at least one capacitive sense electrode to control the at least one operation.
14. The system of claim 11 , wherein the at least one symbol icon is associated with:
an LED indicator at the smooth topmost surface; and
an LED driver connected to the LED indicator.
15. The system of claim 14 , wherein the LED indicator emits light upon activation of the at least one capacitive sense electrode.
16. The system of claim 10 , wherein a mobile device configured to access a web site hosted by a remote server is used by a user to configure or set-up the first loudspeaker.
