Amplifier system

An amplifier system is described. The amplifier system may amplify an audio signal transmitted via a connected loudspeaker in a first mode of operation. In a second mode of operation the amplifier system may amplify a signal generated by the loudspeaker operated in reverse as a microphone. Because a...

description	An amplifier system is described. The amplifier system may amplify an audio signal transmitted via a connected loudspeaker in a first mode of operation. In a second mode of operation the amplifier system may amplify a signal generated by the loudspeaker operated in reverse as a microphone. Because a loudspeaker is less sensitive than a microphone the amplifier system may be used to acquire audio at high sound pressure levels for example at a concert or while making a phone-call in a noisy environment for example with a high level of wind noise. 本发明描述了种放大器系统。该放大器系统能够在第操作模式中放大经由连接的扩音器传输的音频信号。在第二操作模式中，该放大器系统能够放大由作为麦克风逆向操作的该扩音器生成的信号。由于扩音器比麦克风比更不敏感，因此该放大器系统能够用于在高声压级下获取音频，例如在音乐会或在例如具有高水平风噪声的嘈杂环境中打电话时。
