Description

Mobile phone with car player function

technical field

The utility model relates to a mobile terminal, in particular to a mobile phone with a vehicle-mounted player function.

Background technique

Now cars have entered the field of private consumption, and self-driving travel has become a way of life for car owners. At present, in the automotive electronic consumer goods, there is a very small electronic product called a car MP3 wireless transmitter, which can be connected to a U disk or an audio signal line, and uses a set frequency modulation (FM, Frequency Modulation ) wireless signal transmission, the radio system on the car is adjusted to the same frequency to receive and play the FM wireless signal.

But in the actual process, there are still many inconveniences, such as:

1. If the car MP3 wireless transmitter uses the car cigarette lighter power supply, once the car is turned off, the power supply will be lost. When it is restarted, it will start playing the songs in the U disk again, and its file management system is very weak.

2. The audio input of the car MP3 wireless transmitter does not match with many electronic entertainment devices, and a conversion cable is needed.

3. Self-driving tour enthusiasts are often equipped with additional mobile phones, which are used as a timely contact tool for the fleet, but the utilization rate of these mobile devices is very low, and the functions are single and expensive; now the entertainment function of mobile phones is also very strong. Although some mobile phones have a hands-free function, the power is too small, and the playback effect is still unsatisfactory.

Utility model content

The technical problem solved by the utility model is to provide a mobile phone with the function of a car player, and the radio can be used as a loudspeaker of the mobile phone.

The technical scheme is as follows:

A mobile phone with a vehicle-mounted player function includes a main board of the mobile phone, the main board of the mobile phone is provided with a sending device, and the sending device is connected with an audio signal source of the mobile phone.

Preferably, the audio signal source is an MP3 player or a microphone of the mobile phone itself.

Preferably, the main board of the mobile phone is provided with a receiving device, and the receiving device is connected to the sending device.

Preferably, the mobile phone is provided with an FM call key, and when the FM call key is pressed, the connection between the receiving device and the sending device is disconnected.

The utility model can send wireless signals with the same frequency or wavelength as the radio, uses the radio as a loudspeaker of the mobile phone, and expands the range of use of the mobile phone. At the same time, the utility model can also enable multiple mobile phones to send and receive wireless signals of the same frequency or wavelength, so that the mobile phones can realize the intercom function.

Description of drawings

Fig. 1 is a structural schematic diagram of a mobile phone motherboard in a preferred embodiment of the present invention.

Detailed ways

The utility model realizes the connection with the radio by integrating the receiving device and the sending device in the mobile phone, and the receiving device and the sending device can adjust the receiving or sending frequency and wavelength. At the same time, the above-mentioned devices need to be installed in the operating system of the mobile phone for easy operation and use.

Below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.

Referring to Figure 1, the structure of the mainboard of the mobile phone is described in detail.

The mobile phone main board 10 is provided with a sending device 11, the frequency and transmission power of the sending device 11 can be adjusted, so as to realize call preemption on the same frequency and change the FM coverage. The sending device 11 is connected with the audio signal source on the mobile phone, and is used to convert the audio signal into a wireless signal of a certain frequency and send it out. The audio signal source can be the MP3 player 12 on the mobile phone. In principle, all audio sources on the mobile phone can be used as the audio signal source. The sending device 11 can be arranged in front of the earphone jack of the mobile phone, and bypassed electronically or mechanically. The transmitting power of the transmitting device 11 can be set on the mobile phone to meet the requirements of FM signal coverage at different distances and realize the function of a mobile phone.

When the utility model is used as a mobile phone car player, the MP3 playback function in the mobile phone can be utilized to select the songs in the mobile phone memory card (comprising SD card or CF card) by the MP3 player 12, and the FM of the sending device 11 is set. The transmission frequency is to adjust the FM transmission frequency to the same frequency band as the car radio, and when the sending device 11 receives the audio signal of the MP3 player 12, the audio signal can be transmitted with a set wireless signal. The radio system in the car makes the radio indirectly play the music in the memory card by receiving the wireless signal, so that people in the car can share the music.

In principle, all audio signal sources on the mobile phone can choose to use FM output, that is, use the car radio as the loudspeaker of the mobile phone.

In order to realize the intercom function of the mobile phone, a receiving device 14 is arranged on the main board 10 of the mobile phone, and the receiving device 14 is connected with the transmitting device 11. The receiving device 14 is used to receive a wireless signal of a certain frequency. Device 11 is the same. The receiving device 14 can adjust its receiving frequency. Within a certain local area, the wireless intercom function using FM can also be realized between the mobile phones through the receiving device 14 and the sending device 11, thereby saving various roaming and other problems of short-distance mobile phones. Communication fee, to realize part of the functions of the mobile station, in order to save the cost of purchasing the mobile station.

In order to make the mobile phone fully function as a mobile station, the microphone 13 of the mobile phone can be connected with the sending device 11, and the microphone 13 can be used as an audio signal source of the sending device 11. For example, in a self-driving tour team, when the mobile phone is under the intercom function, and all team members set the radio on the car to the designated FM frequency band. When a certain car needs to report the situation, a team member can inform the whole team members of the current road conditions and various instructions through the microphone 13, press the FM call key of the mobile phone and hold it during the conversation, during which the sending device 11 of the mobile phone enhances the wireless communication. Transmitting power, covering the expansion range of the entire fleet, the FM call key can be a certain key of the set mobile phone. When the FM call key is pressed, the connection between the sending device 11 and the receiving device 14 is disconnected, and the user's voice enters the mobile phone through the microphone 13 .
