Description

Portable pickup temperature self-adaptation interference equipment system

Technical Field

The utility model relates to a communication equipment technical field, in particular to portable adapter temperature self-adaptation interference equipment system.

Background

The sound pick-up interference equipment is used for shielding the recording in a specific environment, can effectively interfere with the recording equipment of a digital and tape recorder, a video camera and a wiretap, and can effectively interfere with the digital recording pen and the tape recorder with the frequency of 100HZ-20000 HZ. By outputting white noise outside the human hearing frequency range, the recording pen or the recorder only records a piece of buzzing noise, conversation content of a speaker cannot be recorded, and the recorded sound cannot be restored to the voice of the speaker after sound post-processing (because the sound captured by the recording equipment is only noise). Thereby effectively protecting the dialog content from being recorded secretly.

However, the following common phenomena exist in the current market of portable sound pick-up jamming devices in practical use:

firstly, under the low temperature condition, because the flexibility of the soft rubber bonding part of the sound source probe is reduced, the sound source probe cannot emit interference sound wave signals and then fails to start. In northern winter low-temperature weather, the traditional portable interference equipment needs to better solve the problem of low-temperature starting;

second, the external shape of the portable device is not camouflaged, and the camouflaging function is lost because the sound source probe can be directly viewed. In order to facilitate the portable camouflage use, the camouflage problem of hiding the sound source probe needs to be better solved on the premise of not influencing the sound source effect;

thirdly, the existing portable pickup interference devices on the market have the problems that vibration coupling, namely resonance exists between probes, so that abnormal sound easily appears on the probes, and the ears are unpleasant. In order to improve the ear feeling experience of the portable pickup interference device, the problem that the portable pickup interferes with the sound source probe is solved;

fourthly, the sound source circuit of the portable pickup on the common market adopts an inductance resistance device packaged by a large-size direct insertion, so that a chip mounter and a reflow soldering process cannot be used, the production efficiency is reduced, and the circuit board is too large in size and cannot meet the small-size requirement of the interference equipment of the portable pickup. In order to improve the production efficiency of the process and reduce the circuit volume, the problem of replacing the packaging form of a circuit device needs to be solved;

fifth, the conventional portable pickup jamming device cannot effectively interfere with a portion of the pickup due to its fixed interfering signal frequency range and form. In order to improve the interference efficiency, the problem of single frequency range and combination form of the interference signal needs to be solved.

Therefore, the utility model provides a portable single person uses adapter interference equipment system with treasured camouflage appearance charges can detect and automatic adaptation to external ambient temperature to solve above-mentioned problem.
