Abstract
The utility model relates to the technical field of radios, in particular to an automatic tuning device, which is characterized in that a computer device is connected with a light-emitting diode (LED) display, a key input module is connected with the computer device, the computer device is connected with an audio amplifier and a stepper motor, and the stepper motor is connected with an adjusting device. Due to the fact that the computer device is provided with the key input module, the automatic tuning device obtains a key input function, and by means of the audio amplifier, a function of sound output is achieved.
Description
Technical field
The utility model relates to the receiver technics field, is specifically related to the automatic calibration apparatus of a kind of broadcast receiver.
Background technology
Radio tuner is also claimed tuner, and its main effect is to receive wireless frequency modulation/amplitude modulation radio reception broadcast singal, and these signals are demodulated to the reduction audio signal.Radio tuner need be passed through adjustment before use just can reach best radio reception effect.
Existing radio tuner is manual adjustments mostly, but this adjusting process efficient is low, adjustment shortcoming such as inaccuracy as a result; So the appearance of automatic adjustment equipment has been arranged on the market; Scheme like Chinese utility model patent proposition: be equipped with to be used to control the stepping motor of accent batch rotation and to make to transfer and criticize the drive mechanism that is in transmission connection with the stepping motor realization, stepping motor also is connected in data acquisition equipment and the testing software module is installed and stepping motor is rotated the computer installation that control is used.But because this automatic adjustment equipment is too simple, do not have the keyboard input module input information, do not connect audio frequency amplification module etc. yet.
The utility model content
The goal of the invention of the utility model is: to the problem that prior art exists, provide a kind of external world that passes through by the automatic calibration apparatus of the broadcast receiver of key control.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of automatic calibration apparatus, and computer installation is connected with light-emitting diode display, and keyboard input module is connected with computer installation; Computer installation connects audio frequency amplifier and stepping motor respectively, and stepping motor connects transfers batch device.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is:
1, because the computer installation of the utility model is provided with keyboard input module, make this device realize the button input function.
2, owing to be provided with audio frequency amplifier in the utility model, can accomplish sound output function.
