Description
Technical Field
The utility model relates to the technical field of radio recorders, in particular to a Bluetooth digital radio recorder.
Background
The radio recorder restores a high-frequency signal received from an antenna into an audio signal by detection (demodulation), and transmits the audio signal to an earphone or a loudspeaker to be changed into a sound wave. Due to technological advances, there are many different frequencies of radio waves in the sky. If all of these waves are received, the audio signal will be as busy as it is in the city, and the mixing of many sounds will make something inaudible. After the receiving antenna, there is a selective circuit which is used to select the desired signal (station) and to "filter out" the unwanted signals so as not to interfere, i.e. the "select" button used when listening to the broadcast. The output of the selective circuit is a high-frequency amplitude-modulated signal of a selected radio station, which is not used for directly driving an earphone (an electroacoustic device) and must be restored into an original audio signal.
However, the radio cassette recorders on the market at present only have a radio function, or have a plurality of functions which can not be used, such as voice control, fingerprint unlocking and the like, and the functions are numerous and cause high price, large volume and the like, and for the radio cassette recorder for the elderly to have leisure, as the elderly do not need too many functions, only need to have a bluetooth function to connect mobile phone broadcasting music and have a radio function, so that the bluetooth digital radio cassette recorder with low cost, simple functions and stable device system is needed.
