摘要： The present teachings relate to an electronic device comprising: a first module for generating an audio signal; a second module for generating an ultrasonic signal; a mixer for generating a combined signal; a transmitter for outputting an acoustic signal dependent upon the combined signal; and, a processing means for controlling the ultrasonic signal; wherein, in response to receiving a first instruction signal for initiating the ultrasonic signal, the processing means is configured to increase the amount of the ultrasonic signal in the combined signal from an essentially zero value to a predetermined value over a predetermined enable time-period. The present teachings also relate to an electronic device configured to decrease the amount of the ultrasonic signal in the combined signal from an essentially zero value to a predetermined value over a predetermined disable time-period, and to an electronic device configured to remove the audio signal from the combined signal whilst preventing pop-noise, and to an electronic device capable of replacing the ultrasonic signal whilst minimizing the processing time. The present teachings further relate to a method for reducing the occurrence of pop noise in an acoustic signal associated with: initiating the ultrasonic signal in the combined signal, terminating the ultrasonic signal in the combined signal, terminating the audio signal in the combined signal, and replacing the ultrasonic signal in the combined signal. The present teachings also relate to a computer software product for implementing any of the method steps disclosed herein, and to a computer storage medium storing the computer software herein disclosed.

摘要： The present invention relates to a system for controlling access to an external device, including a first device and a second, external device, both including wireless communication units using a common communication protocol. One of said devices includes an acoustic transmitter being configured to transmit acoustic signals at least partially within the ultrasonic range, and the second of the devices includes an acoustic receiver configured to receive acoustic signals at least partially in the ultrasonic range. The transmitted ultrasonic signal has predetermined characteristics and said receiver being configured to recognize said characteristics and, at the receipt of said ultrasonic signal at the second device initiating a wireless communication using said communication protocol.
