The utility model relates to a kind of wireless earphone type microphone of mobile telephone holding-free receiver, refers to a kind of wireless transmission of mobile telephone holding-free receiver especially, and by earphone-type microphone transmitting-receiving sound, thereby make it just more in use.
General, mobile phone directly leans against phone on the cheek and can converse after connection, but drive or by bike the time if there is phone to come in, then be inconvenient to pick up mobile phone and answer, and one hold another hand held mobile phone speech of steering wheel when driving, also can influence the safety when driving.
But for the personage who hurries back and forth outside often, the convenience that then very relies on mobile phone and brought, owing to when driving, receive calls, cause traffic accident easily, so present mobile phone is equipped with the earphone cord of Handless mostly, can when driving, the earphone on the earphone cord be filled at any time on ear, and microphone is hung over the front, when when driving, having phone to come in, then can open the turn-on key of mobile phone can converse, or directly on mobile phone, set and connect the number of times that the back the tinkle of bells rings, the tinkle of bells is connected after reaching the number of times of setting automatically when phone is come in, do not need hand held mobile phone to drive, avoided driving to say the situation of phone generation traffic accident to a certain extent.
But because of the mobile phone earphone cord of must pegging graft, and earphone and microphone are to be connected on the mobile phone with lead, and be inconvenient so have in use that lead is impeded, and earphone cord is subjected to pullling the situation that causes loose contact easily, influences communication quality.
And be general microphone in order to the member that voice are sent on this earphone cord, and microphone hangs over the front when accepting speech, is subjected to the interference of external noise easily, and the noise in the external world is included in the lump, make the other side of conversation can hear noise simultaneously, relatively poor on calling quality.
The purpose of this utility model just is to provide a kind of wireless earphone type microphone of mobile telephone holding-free receiver, its two-way wirelessly transmission signal, can exempt and use earphone cord because of pullling that lead is impeded, cause loose contact and influence speech quality, simultaneously, this earphone-type microphone places ear to receive and dispatch sound, can exempt the interference of external noise, influences speech quality to avoid transmitting noise.
For achieving the above object, the wireless earphone type microphone of a kind of mobile telephone holding-free receiver of the utility model, circuit is by antenna circuit, amplifier, signal modulation circuit is formed, these circuit and an earphone-type microphone, one compact battery all is arranged in the ear type shell, and this amplifier system is connected in this receives the two-way resonance frequency that is produced behind the signal in order to two-way reception mobile phone antenna circuit, distinguish that the signal frequency height after amplifying is connected in this amplifier with the signal modulation circuit of discerning mobile telephone system, described earphone-type microphone is connected in this signal modulation circuit, with transmitting-receiving sound.
According to above-mentioned structure, because this earphone-type microphone is installed in the ear type shell in order to transmitting-receiving sound, and receive the two-way resonance frequency that mobile phone is produced when receiving phone by antenna circuit, again by signal modulation circuit control earphone-type microphone, make it get two-way wirelessly transmission signal, use earphone cord because of pullling that lead is impeded and can exempt, cause loose contact and influence speech quality; And this earphone-type microphone system places ear transmitting-receiving sound and can exempt the interference of external noise, influences speech quality to avoid transmitting noise.
Below by the drawings and specific embodiments the utility model is further described in more detail.
Fig. 1 is a stereogram of the present utility model:
Fig. 2 is a circuit diagram of the present utility model.
At first, referring to Fig. 1, shown in Figure 2, the utility model mainly is to be equiped with an antenna circuit 1, amplifier 2, signal modulation circuit 3, earphone-type microphone 4 and compact battery (not shown) in an ear type shell 10, wherein,
Antenna circuit 1 is to receive the two-way resonance frequency that is produced behind the signal in order to two-way reception mobile phone (not shown).
Signal modulation circuit 3 is connected in amplifier 2, and the signal frequency height that identification is exported through amplifier 2 is just distinguished mobile telephone system by frequency.
Earphone-type microphone 4 is connected in signal modulation circuit 3, has the effect of receiving and transmitting voice, and must differentiate the frequency height that receives with control earphone-type microphone 4 by aforesaid signal modulation circuit 3.
According to above-mentioned structure, ear type shell 10 is placed in the ear, and mobile phone is located at holding state, if there is phone to come in, the turn-on key that then can open mobile phone to be conversing, or sets automatically on mobile phone and connect.And when call completion of mobile telephone, it can produce two-way resonance frequency, this antenna circuit 1 promptly can receive the signal of this two-way resonance frequency, by amplifier 2 received signal is amplified again, this signal modulation circuit 3 is differentiated this signal, if this signal is the system of the mobile phone frequency that sets of a signal modulation circuit 3 for this reason, then control earphone-type microphone 4 and be talking state, can converse.
Otherwise, if the received non-mobile phone frequency that it sets of signal of this signal modulation circuit 3 then makes earphone-type microphone 4 be closed condition, to avoid receiving the telephone signal of non-machine system.
Moreover, the voice signal that receives must directly be sent in the ear by earphone-type microphone 4, the voice signal of desiring to send then is sent to earphone-type microphone 4 by the acoustical vibration frequency that speech the time is produced, oppositely voice signal is sent to antenna circuit 1, by antenna circuit 1 voice signal is sent out again, so promptly be able to two-way the conversation.
Because Handless the time is to transmit by wireless mode in conversation, use earphone cord to have lead to impede so can exempt, pullled the situation that causes loose contact easily and influenced speech quality, comparatively convenient in the use.
Again since ear type shell 10 be placed in the ear, and mobile phone places at one's side usually or the waist border on, transmitting range therebetween is very short, so that the power that transmits does not need is excessive, is eavesdropped avoiding; And very short in when conversation because of the distance that transmits, delivering power between the two greater than extraneous near or the interference power of same frequency, so it is less to be subjected to external interference; If under the very big situation of wave interference, then also can't use together with mobile phone, therefore, under general normal operating position, the situation that is subjected to extraneous wave interference is not the problem of mobile phone and ear type shell 10 wireless transmission between the two.
In addition, because this earphone-type microphone 4 gets two-way reception or sends sound, and it is directly to be placed in the ear, owner's voice is in the mode of solid sound wave to be sent to earphone-type microphone 4 by otica, so no matter how noisy extraneous environment is, also the voice in the external world can be sent to the other side of conversation, therefore, have preferable speech quality.
