chip through an fm signal input pin of the fm chip since a noise ratio in the amplified fm signals is high the fm signals need to be demodulated by the fm chip that is the fm chip performs detection on the received fm signals to filter a noise part in the fm signals and obtain the audio signals used for playing from the fm signals the audio output positive pin of the fm chip is connected with the spk of the speaker the audio output negative pin of the fm chip is connected with the spk u2212 of the speaker and the fm chip transmits the audio signals to the speaker for playing through the audio output positive pin and the audio output negative pin and the fm chip in the embodiment can exist independently and can also be integrated with other chips for example the fm chip can be integrated with a baseband processing chip of a mobile terminal a wifi chip or a bluetooth chip and also can be integrated with the fm chip the wifi chip and the bluetooth chip together in order to implement the method above the disclosure further provides a device for receiving signals wherein the device includes.
