Abstract: An acoustic coupling sensor 200 for a portable electronic device is described which includes an acoustic transmitter 22, a reference signal generator 20 coupled to the acoustic transmitter, and an acoustic sensor 24 wherein in operation, the reference signal generator is operable to transmit the reference signal to the acoustic transmitter, to detect an acoustic level of the transmitted reference signal via the acoustic sensor, and wherein the detected reference signal level corresponds to a value of acoustic coupling between the acoustic transmitter and the acoustic sensor. The acoustic coupling sensor may be used for example in a mobile phone to detect acoustic leakage in order to adapt the acoustic level in the mobile phone during use.

Abstract: A voice activation system is described including a first voice activity detector for receiving a first signal from a microphone; a second voice activity detector for receiving a second signal from a speaker; a voice detector output coupled to the output of the first voice activity detector and the second voice activity detector. The first detector and the second detector are operable to generate an output signal in response to a candidate speech signal received on the respective detector inputs and the voice activation system is configured to generate a voice detector output signal when at least one of the first detector output and the second detector output indicate that speech has been detected. The voice activation system may reduce the average power consumption and increase the recognition rate of an always-on voice activation solution for headsets or other mobile audio devices.

Abstract: Mobile devices such as mobile phones have always-on modes using sensors which respond to changes in the environment. A mobile device is described comprising a loudspeaker; a controller having an input coupled to the loudspeaker. The controller is operable in a first mode of operation to detect an electrical signal generated by the loudspeaker in response to an acoustic input signal. This signal can be used to activate further circuitry. Using a loudspeaker as an acoustic sensor may reduce the power consumption of the mobile device.

Abstract: Accelerometers are used as motion sensors in mobile devices, such as mobile phones, to detect user inputs such as tapping. A motion sensor for a mobile device is described comprising a loudspeaker for outputting an audio signal, the loudspeaker having a loudspeaker input; a trigger detector having a trigger input coupled to the loudspeaker input, and a trigger output; wherein the trigger detector is operable to output a detection signal on the trigger output in response to a mechanically induced signal on the loudspeaker input due to a motion source. The power consumption of the motion sensor is reduced since the loudspeaker does not require any DC bias to detect a motion source such as a user tapping the motion sensor.
