Abstract
Disclosed is a handset protective sleeve provided with a frequency modulation signal emitting module, relating to the handset protective sleeve technical field, with the purpose of overcoming the technical defects of the connection between the handset and the vehicle-loaded sound equipment. The handset protective sleeve mainly comprises a left frame, a right frame, an upper frame, and a lower frame, with the lower frame being provided with a bayonet joint cooperatively inserting into the handset data line interface. The handset protective sleeve is characterized by further comprising a frequency modulation signal emitting module which is connected with the bayonet joint and used for transforming the audio signal of a handset into frequency modulation signal. The frequency modulation signal emitting module is inserted into the data line interface at the bottom of the handset for connection via the bayonet joint and transforms the audio signal of a handset into the frequency modulation signal for sending to the vehicle-loaded radio, with no additional power supply and reducing the volume. Moreover, the handset protective sleeve features high controllability. The frequency modulation signal emitting module is arranged at the lower frame, with no need for connecting line, thereby simplifying the structure and facilitating usage.

Summary of the invention
In sum, the main purpose of the utility model is for there is technical deficiency in the connected mode that solves between mobile phone and vehicle audio, and a kind of mobile phone protective cover that is provided with the FM signal transmitter module that proposes.
For solving the technical problem that the utility model proposed; The technical scheme that adopts is: a kind of mobile phone protective cover that is provided with the FM signal transmitter module; Mainly constitute by left frame, left frame, upper side frame and lower frame; On described lower frame, be provided with and cooperate the connection-peg of pegging graft with the data in mobile phone line interface, it is characterized in that: also include one and be connected the FM signal transmitter module that is used for the audio signal of mobile phone is converted to FM signal with said connection-peg.
Described FM signal transmitter module is located in the lower frame.
Described FM signal transmitter module includes:
One frequency modulation transmitter unit is used to connect the audio output of mobile phone, converts the audio signal of mobile phone to FM signal and is sent to receiving arrangement of frequency-modulated signal;
One control unit is used to connect the control signal output ends of mobile phone, the frequency of regulating the FM signal of frequency modulation transmitter unit according to the control signal of mobile phone output.
The power input of described FM signal transmitter module connects the power output end of mobile phone through connection-peg.
Described frequency modulation transmitter unit adopts model to be: the QN8027FM transmitting chip.
Described control unit adopts a model to be: the chip of C8051F300.
On described left frame, left frame, upper side frame or lower frame, be provided with a USB interface that is connected with connection-peg.
Described connection-peg is the connector of model 514S0117.
The beneficial effect of the utility model is: the utility model mainly is and the supporting use of iPhone4 series mobile phone; Corresponding control programs is installed in mobile phone; The FM signal transmitter module is pegged graft through the data line interface of connection-peg and mobile phone bottom, converts the audio signal of mobile phone to FM signal and sends in the vehicle-mounted radio, the data-interface acquisition of the working power of FM signal transmitter module at the bottom of the mobile phone; Need not to establish separately power supply, reduce volume; The tranmitting frequency of FM signal is freely controlled by the software in the mobile phone, and controllability is strong; Can need not on the mobile phone protective cover of the utility model any button is set, simple in structure, cost is low; The FM signal transmitter module is located in the lower frame, need not connecting line, and simplified structure is easy to use.
