Gesture-controlled tabletop speaker system
A tabletop speaker system includes an amplifier, proximity and acceleration detectors, and a processor. The processor is operatively coupled to receive signals from the proximity and accelerometer detectors, and in response to the proximity and acceleration signals, activate various functions local to the tabletop speaker system to operate and control various behaviors or features of the tabletop speaker system. In this way, the tabletop speaker system can respond to user gestures for a very natural control interface.
1. A speaker system, comprising:
a case;
an audio input structured to couple to an audio device and receive a program audio signal from the audio device;
one or more speakers configured to play an audio output based on the program audio signal, the audio output causing a vibration of the case;
an accelerometer coupled to the case and configured to detect the vibration of the case as well as a user tap on the case;
a computer processor configured to identify a user gesture that includes the tap on the case, to identify the tap apart from the case vibration by processing the detected vibration of the case and the detected user tap on the case based on information from the program audio signal to separate the detected user tap from the detected vibration; and to commence a particular function when a user gesture associated with the particular function is identified by the processor; and
a user-accessible input button coupled to the case and to the computer processor, the computer processor further being configured to identify the user gesture based, at least in part, on a condition of the input button.
2. The speaker system of claim 1 , further comprising a proximity detector mounted in the case and coupled to the computer processor, the proximity detector being configured to sense position and motion of a hand of a user, in which the computer processor is configured to identify the user gesture based in part on the sensed position and motion of the user's hand.
3. The speaker system of claim 1 , further comprising a microphone coupled to the computer processor, the microphone being structured to receive ambient audio sounds and to generate an ambient audio signal from the received ambient audio sounds, in which the computer processor is further configured to identify the tap apart from the case vibration based in part on the ambient audio signal.
4. A speaker system, comprising:

an accelerometer coupled to the case and configured to detect the vibration of the case as well as a user tap on the case;
a computer processor coupled to the microphone, the processor being configured to identify a user gesture that includes the tap on the case, to identify the tap apart from the case vibration by processing the detected vibration of the case and the detected user tap on the case based on information from the ambient audio signal to separate the detected user tap from the detected vibration; and to commence a particular function when a user gesture associated with the particular function is identified by the processor; and
a user-accessible input button coupled to the case and to the computer processor, the computer processor further being configured to identify the user gesture based, at least in part, on a condition of the input button.
5. The speaker system of claim 4 , further comprising a proximity detector mounted in the case and coupled to the processor, the proximity detector being configured to sense position and motion of a hand of a user, in which the processor is configured to identify the user gesture based in part on the sensed position and motion of the user's hand.
