Touch input surface speaker
First Claim
1. A system, comprising:
- a receiver interface configured to receive a source audio signal to be rendered by a touch input medium as a sound outputted by a speaker;
a transmitter interface configured to send a transmitted signal to be propagated through the touch input medium, wherein the transmitted signal includes the source audio signal and a touch location detection signal;
a detector configured to indicate an event where the touch input medium has been contacted at a location on the touch input medium by a touch contact such that rendering of the source audio signal by the touch input medium is affected by the touch contact; and
a signal processor configured to determine the location of the touch contact on the touch input medium by analyzing a disturbance by the touch contact on the rendered touch location detection signal and, based on an expected effect of the touch contact on the touch input medium determined using the indication of the detector, modify at least a portion of the source audio signal to be rendered as the sound outputted by the speaker to at least in part reduce the expected effect of the touch contact on rendering of the sound outputted by the speaker.

Abstract
A source audio signal to be rendered by a touch input medium is received. A transmitted signal to be propagated through the touch input medium is sent. The transmitted signal includes the source audio signal and a touch location detection signal. An event is indicated, where the touch input medium has been contacted at a location on the touch input medium by a touch contact such that rendering of the source audio signal by the touch input medium is affected by the touch contact. The location of the touch contact on the touch input medium is determined by analyzing a disturbance by the touch contact on the rendered touch location detection signal. At least a portion of the source audio signal is modified based on an expected effect of the contact on the touch input medium determined using the indication of the detector.

19. A method, comprising:
-
receiving a source audio signal to be rendered by a touch input medium as a sound outputted by a speaker; sending a transmitted signal to be propagated through the touch input medium, wherein the transmitted signal includes the source audio signal and a touch location detection signal; indicating an event where the touch input medium has been contacted at a location on the touch input medium by a touch contact such that rendering of the source audio signal by the touch input medium is affected by the touch contact; using a processor to determine the location of the touch contact on the touch input medium by analyzing a disturbance by the touch contact on the rendered touch location detection signal; and based on an expected effect of the touch contact on the touch input medium determined using the indication of the detector, modifying at least a portion of the source audio signal to be rendered as the sound outputted by the speaker to at least in part reduce the expected effect of the touch contact on rendering of the sound outputted by the speaker.

20. A computer program product, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:
-
receiving a source audio signal to be rendered by a touch input medium as a sound outputted by a speaker; sending a transmitted signal to be propagated through the touch input medium, wherein the transmitted signal includes the source audio signal and a touch location detection signal; indicating an event where the touch input medium has been contacted at a location on the touch input medium by a touch contact such that rendering of the source audio signal by the touch input medium is affected by the touch contact; determining the location of the touch contact on the touch input medium by analyzing a disturbance by the touch contact on the rendered touch location detection signal; and based on an expected effect of the touch contact on the touch input medium determined using the indication of the detector, modifying at least a portion of the source audio signal to be rendered as the sound outputted by the speaker to at least in part reduce the expected effect of the touch contact on rendering of the sound outputted by the speaker.
