Abstract
The utility model discloses a mobile phone headset which enables many people to talk at the same time. The mobile phone headset comprises a headphone plug, an earplug generator, a pickup device and a traverse. The utility model is characterized in further comprising: a conversion box in series in the traverses and a plurality of suspending ropes provided with the pickup device and connected with the conversion box; a transfer switch, a loudspeaker, an amplifying circuit connected with the pickup device and an adjustable power amplifying circuit connected with the loudspeaker, all arranged in the conversion boxes; a volume adjustment knob arranged at the surface of the conversion boxes. One end of the transfer switch arranged in the conversion boxes is connected with the headphone plug through the traverses. The other end of the transfer switch can be connected not only with the pickup device and the earplug generator but also with the loudspeaker arranged in the conversion box and the pickup device arranged on the hanging ropes. The utility model retrofits a loudspeaker and a plurality of pickup devices to the ordinary mobile phone headset, therefore, the utility model enables many people to talk at the same time.
Description
Technical field
The utility model relates to a kind of mobile phone earphone, refer to especially a kind of realize that many people converse simultaneously have an outer mobile phone earphone of putting with superpower receiving function.
Background technology
The people that appear as of mobile phone realize that contact provides possibility anywhere or anytime.The talking mode of mobile phone mainly contains two kinds: a kind of is that direct built-in generator with mobile phone is placed on the people in one's ear, and the pick-up that mobile phone is built-in (microphone) is placed on people's mouth, converses; Another kind of mode is to utilize the earphone receiving incoming call that has headset plug 1, ear type generator 2 and pick-up 3 as shown in Figure 1 to converse.
Above-mentioned which kind of talking mode all carries out between two people, and the people in needing mobile phone certain distance scope can participate in conversation, when many people converse together simultaneously, above-mentioned two kinds answer, talking mode can't realize.
Summary of the invention
In view of the foregoing, the purpose of this utility model provide a kind of realize that many people converse simultaneously have an outer mobile phone earphone of putting with superpower receiving function.
For achieving the above object, the utility model by the following technical solutions: a kind of mobile phone earphone of realizing that many people converse simultaneously, it is made of headset plug, ear type generator, pick-up, lead, it is characterized in that: it also further comprises:
Be connected on the boxcar in the described lead, the lifting rope that is provided with a plurality of pick-ups that links to each other with boxcar;
In described boxcar, be provided with change over switch, outgoing loudspeaker, amplifying circuit that links to each other with pick-up and the adjustable power amplifier that links to each other with outgoing loudspeaker; Surface at boxcar is provided with volume adjustment knob;
An end that is built in the change over switch in the described boxcar links to each other with headset plug by lead; Its other end can link to each other with pick-up, ear type generator by lead, realize two person-to-person conversations, the other end of change over switch can also link to each other with the outgoing loudspeaker in being built in boxcar, the pick-up that is arranged on the suspender belt, realizes the conversation between many people.
Because the utility model has installed outgoing loudspeaker and a plurality of pick-up additional on common mobile phone earphone, strengthen the scope that mobile phone received and sent call voice, so the utility model can realize that many people converse simultaneously.The utility model has the advantages that: easy to use, answer effective, lamprophonia.

Embodiment
As shown in Figure 2, the utility model disclosed realize many people converse simultaneously have outer put with the mobile phone earphone of superpower receiving function by headset plug 1, ear type generator 2, pick-up 3, lead 4, be connected on boxcar 5 in the lead 4, link to each other with boxcar 5 be provided with a plurality of pick-ups 3 ' lifting rope 6 constitute.In boxcar 5, be provided with change over switch 7, outgoing loudspeaker 8, be arranged on lifting rope 6 on pick-up 3 ' amplifying circuit 9 that links to each other and adjustable power amplifier 10 that links to each other with outgoing loudspeaker 8.Surface at boxcar 5 is provided with volume adjustment knob.
As shown in Figure 3, an end that is built in the change over switch 7 in the boxcar 5 links to each other with headset plug 1 by lead 4; Its other end can link to each other with pick-up 3, ear type generator 2 by lead 4, realizes the conversation between two people, can also be with outgoing loudspeaker 8 in being built in boxcar 5, be arranged on pick-up 3 on the suspender belt 6 ' link to each other, realize that many people converse simultaneously.
As shown in the figure, when the contact 1,3 of change over switch 7 is connected, voice signal passes in listener's the ear through earphone jack, headset plug 1, lead 4, the ear type acoustical generator 2 of mobile phone, listener's sound is passed to the caller through pick-up 3, lead 4, headset plug 1, mobile phone earphone jack, mobile phone, realizes two person-to-person conversations.Contact 1 when change over switch 7, during 2 connections, the voice signal that mobile phone receives is through the earphone jack of mobile phone, headset plug 1, lead 4, be built in the adjustable power amplifier 10 that links to each other with outgoing loudspeaker 8 in the boxcar 5, outgoing loudspeaker 8 plays back, make the other a plurality of people of mobile phone hear sound simultaneously, the sound that other everyone of mobile phone sends can be by pick-up 3 ' pick up, through with after the amplifying circuit 9 of pick-up 3 ' link to each other amplifies, through headset plug 1, the mobile phone earphone plug, mobile phone is passed to the caller of the mobile phone other end, realizes that many people converse simultaneously.
Fig. 4 is the utility model pick-up amplifying circuit physical circuit figure.As shown in the figure, the audio signal of pick-up 3 ' receive is amplified the back through the secondary of T3, T4 again and is exported after capacitor C 1 is coupled to the first order amplifying circuit of being made up of triode T1, T2, resistance R 2, R3 and amplifies.Because the utility model pick-up 3 ' sound that picks up amplifies the back through two-stage to be exported, so, the utlity model has superpower receiving function.
Fig. 5 is the adjustable power amplifier physical circuit of the utility model outgoing loudspeaker figure.As shown in the figure, the audio signal of mobile phone output is played back by outgoing loudspeaker 8 after amplifying by the power amplifier chip 34119 of earphone jack in Fig. 5.The I that gives great volume of loud speaker 8 outputs is regulated by the resistance of the adjustable potentiometer W of connection between regulatory work rate amplifier chip 34119 pins 4,5 according to site environment.
