Abstract
The utility model discloses an electromagnetic pickup device which comprises a shell body, wherein an amplifier is arranged in the shell body; one end of the amplifier is connected with an electromagnetic induction head by an input line; the other end of the amplifier is connected with an output hole by an output line; a volume control device is also connected with the amplifier; and an earphone or a loudspeaker is connected with the output hole. After the electromagnetic pickup device converts a magnetic field generated by electric current into electrical signals, electromagnetic pickup operations such as electromagnetic pickup, voice monitoring, concealed wiring detection and the like can be carried out. The electromagnetic pickup device has simple structure and low cost, is convenient to manufacture and use and can be popularized and applied on a large scale.
Description
Technical field
The utility model relates to a kind of electromagnetism pick device.
Background technology
Thereby the charge movement that is of electromagnet phenomenon produces fluctuation formation magnetic field.How to pass through induction, come the transmission line road is discerned, output signal is monitored a problem that becomes people's research magnetic field.But this type of present device is with high costs mostly, makes complexity, can't make application on a large scale.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and electromagnetism pick-up a kind of simple in structure, applied widely is provided.
The electromagnetism pick-up that the utility model provides comprises housing, is provided with amplifier in the described housing, and described amplifier one end is connected on the electromagnetic induction head by incoming line, and the other end is connected on the delivery outlet by outlet line.
Preferably, also be connected with sound volume control device on the described amplifier.
Preferably, be connected with earphone or public address set on the described delivery outlet.
After converting the signal of telecommunication to, the magnetic field that the utility model produces electric current can carry out the work that electromagnetism such as electromagnetism pickup, sound monitoring, dark line detection pick up the aspect.And simple in structure, with low cost, make easy to usely, can be applicable on a large scale.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples only are used to the utility model is described but not are used to limit scope of the present utility model.
Referring to Fig. 1, the electromagnetism pick-up that the utility model provides comprises housing 1, is provided with amplifier 2 in the described housing 1, and described amplifier 2 one ends are connected on the electromagnetic induction head 3 by incoming line, and the other end is connected on the delivery outlet 4 by outlet line.
Preferably, also be connected with sound volume control device 5 on the described amplifier 2.
Preferably, be connected with earphone or public address set on the described delivery outlet 4.
When being applied in dark line detection, the electromagnetic induction head 3 of electromagnetism pick-up can be close to metope and move, when buzz occurring in the earphone, near showing concealed wire is arranged, move around again, when buzz was the loudest in the earphone, concealed wire was just below electromagnetic induction head 3; When seeking broken string, drone sound maximum is drawn line, determine the electric wire trend, when somewhere sound reduced gradually, the broken string position was just herein.
When phone, mobile phone need amplify when emitting, near phones, the speaker center of mobile phone inserts loudspeaker and gets final product on the delivery outlet 4 of electromagnetism pick-up with the electromagnetic induction head 3 of electromagnetism pick-up.
When the output circuit to Public Address System does not have the monitoring of the signal of connection, electromagnetic induction head 3 is close to output line, from earphone, just can hear broadcast, output signal is monitored.When electromagnetic induction head 3 contact output line somewheres, earphone does not ring, and is exactly the place that fault takes place herein, can be to place under repair herein.
