Background technology
Due to the needs of criminal investigation, be one of very important and necessary means to the monitoring of offender, for the raising of the counter-investigation ability of offender, need more advanced equipment and technology.Existing audiomonitor volume is too huge, during monitoring, probe needs to contact metope stably, and it is also relevant with the factor such as thickness, material of wall to monitor effect, probe locations arbitrarily can not dismantle touching, cause the scope of application extensive not, and service precision is not high yet, present needs can not be met.
Summary of the invention
Object of the present invention be exactly providing a kind of superior performance to overcome defect that above-mentioned prior art exists, can use in different occasion, the single-magnetic head through-the-wall listener of simple and fast.
Object of the present invention can be achieved through the following technical solutions:
Single-magnetic head through-the-wall listener, it is characterized in that, this monitor comprises main frame, probe, probe through walls and earphone, described main frame top arranges volume switch, frequency adjustment switch, probe insertion, charging jacks, antenna jack, recording jack and earphone jack, described volume switch and frequency adjustment switch are cylindric, be located at the side on main frame top, described probe insertion is located at the side of frequency adjustment switch, described charging jacks is located at the side of probe insertion, described antenna jack and recording jack are located at the below of probe insertion, described earphone jack is located at the below of frequency adjustment switch, described probe, probe through walls and earphone are connected with main frame.
Described probe is magnetic probe, and this probe inside arranges magnet.
Described probe and probe through walls connect through wire, and wire rear end arranges plug, and this plug is connected with probe insertion.
The rear end of described earphone arranges headset plug, and this headset plug is connected with earphone jack.
Described frequency adjustment switch arranges fourth gear and selects.
Compared with prior art, the present invention has the following advantages:
(1) superior performance, sound clarity, sensitivity is strong, and sensor sensitivity is up to-70db, and highest audio multiplication factor can reach 20000 times;
(2) four gears try to find out adjustment, use under can meeting different condition, can through-fall mud wall, reinforcing bar wall, Mu Qiang, glass, hollow brick etc.;
(3) probe through walls configured has the function of on-site monitoring;
(4) antenna jack main frame configured and recording jack can connect wireless transmission assembly, external recording equipment, signal wireless can be transferred to and monitor at a distance, and can synchronization, use simple and fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
