Abstract
Provided is a hand-free structure for an interphone. An earphone and a mini microphone are manufactured and are connected in parallel. Positive and negative electrodes of the earphone and the microphone in parallel connection are connected with a positive electrode and a negative electrode of a plug. After the plug is inserted into a jack on the interphone, a positive electrode and a negative electrode of an original circuit are in butt joint with the positive and negative electrodes of the plug, and on the other hand, are separated from a positive electrode and a negative electrode of an original loudspeaker. One of the implementation methods is to refer to the design of a hand-free microphone, an earphone jack and a circuit of a cellphone. Another method is to separate, at the jack part, the positive electrode and the negative electrode of the original circuit which is in connection with the loudspeaker. A new component is designed and manufactured for the switching function, so that the earphone and the microphone substitute for the loudspeaker and achieve the sound transmission function.
Description
Technical field
The utility model relates to a series of handsfree construction about intercom.
Background technology
Now present intercom owing to there is no hands-free technology, causes inconvenience in use.
Summary of the invention
In order to overcome intercom due to the inconvenience that does not have hands-free technology to bring to people, the utility model provides a series of handsfree construction about intercom.Should can provide many convenience to people about the handsfree construction of intercom.
The technical scheme that the utility model provides is: about the handsfree construction of intercom, be equipped with exactly an earphone, a microtelephone.Earphone and microphone are in parallel.Earphone after parallel connection, the positive pole of microphone, the positive pole of negative pole attachment plug, negative pole.The positive pole of the positive pole of the original circuit after plug inserts of the jack on intercom, negative pole one side and plug, negative pole docking; Separate with positive pole, the negative pole of original loud speaker on the one hand.Its implementation is a kind of is that the hands-free microphone with reference to mobile phone, jack and the circuit of earphone are equipped with.To be the positive pole that makes the circuit of original connection loud speaker, negative pole disconnect at the jack place a kind of method.Circuit anode after disconnection, negative pole connect positive pole, the negative pole docking of positive pole, negative pole and the jack of interphone antenna one end.Connect positive pole, the negative pole docking of positive pole, negative pole and newly-increased parts of loud speaker one end.These newly-increased parts are not when plug inserts jack, and it is positive pole, the negative pole to connecting jack under the effect of the spring mechanism that arranges.At this moment loud speaker continues the original function of answering, send words of performance.Spring mechanism can be subject to the compacting of plug.After plug inserted jack, the relevant position compacting spring mechanism of plug separated positive pole, the negative pole of positive pole, negative pole and the jack of newly-increased parts.At this moment, words can't be answered, be sent to loud speaker.And the positive pole of the plug that earphone, microphone connect, negative pole to the positive pole that connects jack, negative pole after.Earphone, microphone have replaced the function that words were answered, sent to loud speaker.Perhaps only have a positive pole or only have a negative pole on newly-increased parts.Plug is plugged the electrode separation that rear loud speaker just has an electrode and jack like this, and so words just can't be answered, be sent to loud speaker.
Perhaps earphone, microphone are not in parallel, are separately independently.The positive pole of earphone, negative pole, the positive pole of microphone, negative pole be two pairs of positive poles, the negative pole of banjo respectively.The circuit of jack is equipped with the hands-free microphone with reference to mobile phone, the circuit of earphone jack is equipped with.
The beneficial effects of the utility model are due to hands-free technology having been arranged, to make intercom that purposes widely be arranged.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is that the utility model is about the handsfree construction schematic diagram of intercom.
In figure: 1, intercom.2, the hands-free microphone of intercom and Headphone structure.
Embodiment
Embodiment one, about the handsfree construction of intercom, be equipped with exactly an earphone, a microtelephone.Earphone and microphone are in parallel.Earphone after parallel connection, the positive pole of microphone, the positive pole of negative pole attachment plug, negative pole.The positive pole of the positive pole of the original circuit after plug inserts of the jack on intercom, negative pole one side and plug, negative pole docking; Separate with positive pole, the negative pole of original loud speaker on the one hand.See accompanying drawing 1.Its implementation is equipped with reference to the hands-free microphone of mobile phone, jack and the circuit of earphone.
Embodiment two, about the handsfree construction of intercom, be equipped with exactly an earphone, a microtelephone.Earphone and microphone are in parallel.Earphone after parallel connection, the positive pole of microphone, the positive pole of negative pole attachment plug, negative pole.The positive pole of the positive pole of the original circuit after plug inserts of the jack on intercom, negative pole one side and plug, negative pole docking; Separate with positive pole, the negative pole of original loud speaker on the one hand.To be the positive pole that makes the circuit of original connection loud speaker, negative pole disconnect at the jack place its implementation.Circuit anode after disconnection, negative pole connect positive pole, the negative pole docking of positive pole, negative pole and the jack of interphone antenna one end.Connect positive pole, the negative pole docking of positive pole, negative pole and newly-increased parts of loud speaker one end.These newly-increased parts are not when plug inserts jack, and it is positive pole, the negative pole to connecting jack under the effect of the spring mechanism that arranges.At this moment loud speaker continues the original function of answering, send words of performance.Spring mechanism can be subject to the compacting of plug.After plug inserted jack, the relevant position compacting spring mechanism of plug separated positive pole, the negative pole of positive pole, negative pole and the jack of newly-increased parts.At this moment, words can't be answered, be sent to loud speaker.And the positive pole of the plug that earphone, microphone connect, negative pole to the positive pole that connects jack, negative pole after.Earphone, microphone have replaced the function that words were answered, sent to loud speaker.Perhaps only have a positive pole or only have a negative pole on newly-increased parts.Plug is plugged the electrode separation that rear loud speaker just has an electrode and jack like this, and so words just can't be answered, be sent to loud speaker.
Embodiment three, on the basis of embodiment one, perhaps earphone, microphone are not in parallel, are separately independently.The positive pole of earphone, negative pole, the positive pole of microphone, negative pole be two pairs of positive poles, the negative pole of banjo respectively.The circuit of jack is equipped with the hands-free microphone with reference to mobile phone, the circuit of earphone jack is equipped with.
