Abstract
The utility model provides a vehicle-mounted frequency modulation carrier wireless device. The vehicle-mounted frequency modulation carrier wireless device comprises a high-frequency modulation transmission unit and a transmitting antenna. An output end of the high-frequency modulation transmission unit is connected with the transmitting antenna. The vehicle-mounted frequency modulation carrier wireless device is characterized in that the vehicle-mounted frequency modulation carrier wireless device further comprises an audio-frequency input interface unit, and the output of the audio-frequency input interface unit is connected with the high-frequency modulation transmission unit. By adopting the utility model, audio-frequency signals of an intelligent mobile phone can be conveniently obtained and can be transmitted to a vehicle-mounted frequency modulation radio after frequency modulation, so that the intelligent mobile phone can be employed as an audio-frequency source of vehicle-mounted audio-frequency equipment.
Description
Technical field
The utility model relates to a kind of vehicle-mounted frequency modulated carrier wireless device, and it belongs to the modulated transmitting device class.
Background technology
Along with the development of electronic technology, smart mobile phone is obtaining development rapidly in recent years, and the universal people of making of height more and more rely on smart mobile phone on the living conditions for counsel, carry, a moment not from.Smart mobile phone is except having powerful network function, also very abundant on application function, also substantially exceeded conventional audio & video equipment on performance simultaneously, substitute some conventional audio & video equipments with smart mobile phone and become possibility, particularly, as the audio-video source aspect of some old vehicles, smart mobile phone is well worth doing, because the vehicle-mounted audio & video equipment of some vehicles is relatively backward at present, such as on many vehicles, the audio-source of audio frequency apparatus adopts or CD player.But smart mobile phone is that as the problem of the audio-source existence of vehicle-mounted audio device many vehicle-mounted audio devices do not possess the adaptable interface that connects external audio source, special is that this is transformed automobile audio circuit, waste time and energy, improvement cost is also higher, according to the above, obviously prior art has further improved necessity.
Summary of the invention
The purpose of this utility model is to provide a kind of vehicle-mounted frequency modulated carrier wireless device, the problem existed to overcome prior art.
A kind of vehicle-mounted frequency modulated carrier wireless device of the present utility model, comprise high frequency modulated transmitter unit, transmitting antenna, the output of described high frequency modulated transmitter unit is connected to transmitting antenna, characterized by further comprising the audio input interface unit, the output of described audio input interface unit is connected to the high frequency modulated transmitter unit.
This vehicle-mounted frequency modulated carrier wireless device of the present utility model, can link up by the audio output interface of audio input interface unit and wire and smart mobile phone the audio signal that obtains smart mobile phone output, be sent to again the high frequency modulated transmitter unit, modulate and amplify by antenna transmission and go out through frequency modulation, at this moment, as long as the receive frequency of vehicle-mounted FM receiver is transferred on the frequency with frequency modulated carrier wireless device of the present utility model, vehicle-mounted FM receiver just can receive this FM signal, finally by vehicle-mounted audio system, play back, adopt the existing car audio system of the utility model to adopt easily smart mobile phone as audio-source, obviously the purpose of this utility model is achieved.
As further improving, also comprise MCU, keyboard unit and display unit, described keyboard unit and display unit are connected to MCU, described MCU is connected to the high frequency modulated transmitter unit, can adjust by keyboard unit modulating frequency and the frequency modulation tranmitting frequency of high frequency modulated transmitter unit like this, and show operating state of the present utility model by display unit, facilitated use.
