Abstract
A wireless hand-free safety helmet capable of receiving mobile phones comprises a helmet body 1 and is characterized in that a micro transmitter and receiver 2 is arranged at a position, corresponding to ears and mouths of a wearer, on one side in the helmet body, a first wireless transceiver 3 is arranged in the transmitter and receiver, and a second wireless transceiver 4 corresponding to the first wireless transceiver is connected to a mobile phone. The utility model provides a motorcycle rider uses the problem of mobile phone for the navigating mate can talk over without handheld mobile phone, has made things convenient for the navigating mate to use mobile phone greatly, and has eliminated the hidden danger of traffic accident from this.
Description
The utility model relates to a kind of safety cap of usefulness by motorcycle, particularly relates to the safety cap that a kind of wireless heldfree type can be answered mobile phone.
Many characteristics such as China's mobile phone development at present is rapid, and mobile phone is small and exquisite with its volume, is easy to carry, and is easy to use, and it is clear to converse are loved by the people, and bring convenience for people live.But mobile phone characteristics easy to use also become the major reason that causes traffic accident.Many human pilots are driving a car, are still using mobile phone during motor vehicles such as motorcycle, owing on the motor vehicles such as existing automobile, motorcycle car phone is not set as yet, therefore human pilot all uses common mobile phone, and when using mobile phone, must drive on the other hand again, another hand cell-phone so just is difficult to avoid causing traffic accident.Particularly because the motorcycle speed of a motor vehicle is very fast, use mobile phone in the time of by motorcycle, then danger is bigger.
The purpose of this utility model is to provide a kind of and is connected with mobile phone by wireless mode, human pilot can be conversed without hand held mobile phone, and easy to use, the wireless clearly heldfree type of conversing can be answered the safety cap of mobile phone, to guarantee personnel's safety by bike.
For achieving the above object, the utility model provides a kind of wireless heldfree type can answer the safety cap of mobile phone, this safety cap comprises cap body 1, it is characterized in that, in the cap body side and wearer ear and oral area corresponding position be equipped with miniaturely give, receiver 2, send, first wireless transceiver 3 be housed in the receiver, be connected with on the employed mobile phone and corresponding second wireless transceiver 4 of described first wireless transceiver.
Described first wireless transceiver 3 is connected in series successively by sound discharge road 31, oscillator 32, frequency multiplier 33, low pass filter 34, high-frequency amplifier circuit 35, frequency mixer 36 and sound discharge road 37 and forms, wherein low pass filter is connected with antenna, on the frequency mixer and be connected to local-oscillator circuit 38, sound discharge road 31,37 is connected with receiver with transmitter respectively.
Described second wireless transceiver 4 is connected in series successively by sound discharge road 41, oscillator 42, frequency multiplier 43, low pass filter 44, high-frequency amplifier circuit 45, frequency mixer 46 and detecting circuit 47 and forms, wherein low pass filter is connected with antenna, sound discharge road is connected with plug in machine audio input jack with mobile phone voice output jack respectively with detecting circuit, on the frequency mixer and be connected to local-oscillator circuit 48.
As seen from the above technical solution, the utility model personnel by motorcycle of having solved use the problem of mobile phone.Since on safety cap, be provided with miniaturely give, receiver, and mobile phone is connected with safety cap by wireless mode, thereby human pilot can be conversed without hand held mobile phone, greatly facilitate human pilot and use mobile phone, and eliminated the hidden danger of traffic accident thus, have important effect to guaranteeing traffic safety.Simultaneously, because the utility model is provided with amplifying circuit, it is clear therefore to converse, the speech quality that has guaranteed.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a schematic perspective view of the present utility model.
Fig. 2 is the utility model structure cutaway view.
Fig. 3 is second wireless transceiver and mobile phone connection diagram.
Fig. 4 is the first wireless transceiver configuration schematic diagram.
Fig. 5 is the second wireless transceiver configuration schematic diagram.
The safety cap that wireless heldfree type of the present utility model can be answered mobile phone is the hands-free message equipment that is provided with mobile phone at existing motorcycle on safety cap.Existing motorcycle divides two kinds basically with safety cap, and a kind of is that cap body front portion all is a windshield, and is another kind of then be that the mid portion of cap body front portion is provided with windshield.Present embodiment is applicable to above-mentioned two kinds of safety caps.
The utility model structure as shown in Figure 1 and Figure 2, a side and wearer ear and oral area corresponding position are equipped with that micro radio send, receiver 2 in cap body 1, it is screwed in cap body inboard.This send, receiver is by the mini microphone 21 that is positioned at the rhabodoid two ends, constitute with earphone 22, for realizing the wireless connections of mobile phone and safety cap, sending, first wireless transceiver 3 is housed in the receiver 2, it constitutes as shown in Figure 4, this transceiver is by sound discharge road 31, oscillator 32, frequency multiplier 33, low pass filter 34, high-frequency amplifier circuit 35, frequency mixer 36 and sound discharge road 37 are connected in series successively and form, wherein low pass filter is connected with antenna (ANT), on the frequency mixer and be connected to local-oscillator circuit 38, sound discharge road 31,37 are connected with receiver (SPK) with transmitter (MIC) respectively.Match with described first wireless transceiver 3, on employed mobile phone 5, be connected with and corresponding second wireless transceiver of described first wireless transceiver 4 (see figure 3)s by tone frequency channel wire 6, it constitutes as shown in Figure 5, it is by sound discharge road 41, oscillator 42, frequency multiplier 43, low pass filter 44, high-frequency amplifier circuit 45, frequency mixer 46 and detecting circuit 47 are connected in series successively and form, wherein low pass filter is connected with antenna (ANT), sound discharge road is connected with plug in machine audio input jack with mobile phone voice output jack respectively with detecting circuit, on the frequency mixer and be connected to local-oscillator circuit 48.Above-mentioned device and circuit all adopt commercially available prod or custom circuit.
The utility model operation principle such as Fig. 4, shown in Figure 5, the audio signal of mobile phone is done the audio frequency amplification through the sound discharge road 41 that audio output jack exports second transceiver 4 to, behind oscillator 42 and low pass filter 44 frequency modulation, is launched by antenna.After first transceiver receives signal, low pass filter 34 through transmit-receive sharing enters high-frequency amplifier circuit 35 amplifications, enters frequency mixer 36 and local-oscillator circuit 38 then, produces operating frequency, promote loudspeaker (SPK) pronunciation after amplify on sound discharge road 37, earphone 22 is talked about.
The voice signal of microphone 21 carries out automatic gain control in 31 and amplifies and the speech sensitivity adjustment in sound discharge road, carry out frequency modulation through oscillator 32 and low pass filter 34, launches through antenna (ANT) then.The antenna of second wireless transceiver 4 receives the voice wireless signal of first wireless transceiver emission, low pass filter 44 through transmit-receive sharing enters high-frequency amplifier circuit 45, enter frequency mixer 46 and local-oscillator circuit 48 then, produce operating frequency, behind detecting circuit 47 audio detection signals, enter mobile phone and further carry out the signal processing.
