Abstract
The utility model discloses a three -dimensional acoustic -electric key frequency sign indicating number radio, including control chip and receiving and dispatching antenna, control chip amplifies the module with the receiving and dispatching antenna through radio reception and connects, and the control chip electricity is connected with the power, and the input of electronic governor and digital tuning module is connected to control chip's output electricity respectively, electronic governor's output electricity connection micro step motor's control end, and micro step motor's output shaft has the harmonious pointer of channel selection. This three -dimensional acoustic -electric key frequency sign indicating number radio carries out accurate control through electronic governor to micro step motor to the more accurate harmonious pointer of control channel selection prevents the harmonious pointer speed of channel selection at the excessive speed and skip and like the broadcasting program that listens to, and the conversion and the signal that the humorous pair of module of the number of pass tone of chinese characters was received digitize prevents the distortion that the signal caused at the in -process of changing, exports the stereo reduction of this signal, rethread external speaker through stereo emission module at last.
Description
Technical field
The utility model relates to receiver technics field, is specially a kind of three-dimensional acoustic-electric key digital radio frequently.
Background technology
Broadcast receiver as a kind of electronic equipment widely use by people, life for people brings unlimited enjoyment, traditional broadcast receiver is with the broadcast program of radio signal propagation, but, now, China has started to promote Digital Television cable network widely, Set Top Box not only can receive abundant digital television program, and free digital broadcast program can be received, but digital cable customers utilizes Set Top Box TV reception mostly, and for the user of program of wanting to listen to the radio programme, not only cost is high to use Set Top Box, power consumption is high, nor just with carry with, for this reason, we propose a kind of three-dimensional acoustic-electric key digital radio frequently.
Utility model content
The purpose of this utility model is to provide a kind of three-dimensional acoustic-electric key digital radio frequently, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of three-dimensional acoustic-electric key digital radio frequently, comprise control chip and dual-mode antenna, described control chip is connected by radio reception amplification module with dual-mode antenna, described control chip is electrically connected with power supply, the output of described control chip is electrically connected the input of electron speed regulator and digital tuning module respectively, the control end of the output electrical connection micro-step motor of described electron speed regulator, the output shaft of described micro-step motor is connected with the tuning pointer of channel selection, the input of the output electrical connection digital volume adjustment module of described digital tuning module, the output of described digital volume adjustment module is electrically connected the input of stereo transmitter module, the output of described stereo transmitter module is electrically connected with external speaker.
Preferably, described power supply is built-in charging accumulator or external power supply.
Preferably, described dual-mode antenna is telescopic antenna.
Preferably, the model of described stereo transmitter module is VMA2016.
Compared with prior art, the beneficial effects of the utility model are: this three-dimensional acoustic-electric key frequently digital radio is controlled micro-step motor accurately by electron speed regulator, thus control the tuning pointer of channel selection more accurately, prevent the tuning speed of finger of channel selection too fast and skip the broadcast program liking listening to, and by digital tuning module, digitlization conversion is carried out to the signal received, the distortion that anti-stop signal causes in the process of conversion, finally by stereo transmitter module to the stereo reduction of this signal, then exported by external speaker.
Accompanying drawing explanation
Fig. 1 is system configuration schematic diagram of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of three-dimensional acoustic-electric key digital radio frequently, comprise control chip and dual-mode antenna, control chip is connected by radio reception amplification module with dual-mode antenna, dual-mode antenna is telescopic antenna, control chip is electrically connected with power supply, power supply is built-in charging accumulator or external power supply, the output of control chip is electrically connected the input of electron speed regulator and digital tuning module respectively, the control end of the output electrical connection micro-step motor of electron speed regulator, the output shaft of micro-step motor is connected with the tuning pointer of channel selection, the input of the output electrical connection digital volume adjustment module of digital tuning module, the output of digital volume adjustment module is electrically connected the input of stereo transmitter module, the output of stereo transmitter module is electrically connected with external speaker, the model of stereo transmitter module is VMA2016.This three-dimensional acoustic-electric key frequently digital radio is controlled micro-step motor accurately by electron speed regulator, thus control the tuning pointer of channel selection more accurately, prevent the tuning speed of finger of channel selection too fast and skip the broadcast program liking listening to, and by digital tuning module, digitlization conversion is carried out to the signal received, the distortion that anti-stop signal causes in the process of conversion, finally by stereo transmitter module to the stereo reduction of this signal, then exported by external speaker.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
