| 摘要 | A set of headphones includes a connector with a first connection contact and a second connection contact as well as a loudspeaker, which is connected to the first connection contact in order to supply a loudspeaker signal. The set of headphones also includes a first and a second digital microphone, each of which is set up to generate a digital microphone signal, in particular with a binary bit stream. A multiplexer, which is coupled, at an output, to the second connection contact, is set up to generate a coded multiplex signal at the output on the basis of the microphone signals. | ||

| 主权项 | 1. A set of headphones comprising: a connector with a first connection contact and a second connection contact; a loudspeaker, which is connected to the first connection contact in order to supply a loudspeaker signal; a first digital microphone, which is set up to generate a first digital microphone signal, in particular with a binary bit stream; a second digital microphone, which is set up to generate a second digital microphone signal, in particular with a binary bit stream; a multiplexer, which is coupled, at an output, to the second connection contact, and which is set up to generate a coded multiplex signal at the output on the basis of the first microphone signal and of the second microphone signal; and a modulator, which is connected between the output of the multiplexer and the second connection contact, and which is configured to perform a signal adaptation at the second connection contact based on the coded multiplex signal in order to carry out a background noise reduction. | ||
