Problems solved by technology

The reason for this is that the adaptive AEC filter does not optimally simulate the room characteristics, so after filtering out acoustic echoes, the interference of the signal is roughly proportional to the volume of the device itself

Embodiment Construction

[0018]In this case, the audio device 1 firstly has an audio signal source 6 . Among the audio signal sources 6, a CD player is, for example, a CD drive, a scanning device, and an electronic device for converting the measured light data into an audio signal. The audio signal generated by the audio signal source 6 is then passed to an amplification stage 8 , for example a conventional output stage 8 , and output from there via an audio output device 2 , here a conventional loudspeaker 2 .

[0019] For control, the device 1 described has a control device 5 which can be implemented, for example, in the form of a microcontroller or the like. The audio signal source 6 can be controlled by means of the control device 5 , for example to select specific titles on a CD. This control possibility is indicated in the drawing by the control line 18 shown. Likewise, the volume of the device 1 can also be adjusted via the control device 5 . This is achieved by controlling the final stage 8...

Abstract

The invention relates to a method of controlling a device (1) comprising an acoustic output means (2) by means of acoustic command signals (BS). The invention proposes that the device (1) automatically reduce its volume if the device (1) recognizes that an acoustic command signal has been sent to the device (1).

Description

technical field [0001] The invention relates to a method for controlling a device with an audio output device by means of an audio command signal. Furthermore, the invention relates to a device with an audio output device, which has a receiving device for receiving an audio command signal, a recognition device for recognizing the command signal, and a device for The command signal controls the control means of the device. Background technique [0002] In order to increase the user-friendliness and usability of devices - especially in the range of consumer electronics - and thereby make said devices more attractive, more and more devices are being equipped in such a way that they can be Voice commands to control the device. Thus, controllable devices such as alarm bells or light sources have long been available on the market, which can be switched on or off, for example, by means of very simple acoustic command signals - such as noises and slaps or disturbances - or at diff...
