Abstract
Cell phone mobile power source having an alarm antiriot and body-protecting function is disclosed. The cell phone mobile power source having an alarm antiriot and body-protecting function comprises a cell phone mobile power source shell body, a battery power source and a power source control circuit board, wherein the battery power source and the power source control circuit board are mounted in the cell phone mobile power source shell body, and the cell phone mobile power source shell body is provided with a cell phone interface and a power source interface which are connected with the power source control circuit board. A loudspeaker and an alarm press key are mounted in the cell phone mobile power source shell body. An alarm circuit is mounted in the cell phone mobile power source shell body, wherein a work power source is supplied to the alarm circuit by a battery, and the alarm circuit is controlled by the alarm press key while being connected with the alarm press key. The alarm circuit consists of a multifunctional sound device circuit, a preamplifier circuit, a power amplifier circuit and the loudspeaker, wherein the multifunctional sound device circuit, the preamplifier circuit, the power amplifier circuit and the loudspeaker are connected orderly. The cell phone mobile power source having an alarm antiriot and body-protecting function is characterized by reasonable design, simple structure, portability, power supply function and antiriot and body-protecting function, good safety performance, and wide application.
Description
Technical field
The utility model relates to a kind of supply unit, is specifically related to a kind of mobile phone portable power source with the anti-riot flak jacket function of reporting to the police.
Background technology
Existing mobile phone claims mobile phone again, use very extensive popularizing, become requisite communication tool in people's work and the life, because the traffic is big, operating time is long, depend in the mobile phone often electric weight deficiency of electroplax alone, particularly go on business, tourism, field work etc., cellular phone power supplies does not have midway, greatly influence the normal work of people and life, as will charge and extremely inconvenient temporarily, be difficult to realize, therefore need to be equipped with the mobile phone portable power source.Meanwhile, the user of mobile phone portable power source goes out at dead of night and handles affairs to the by-place, and in case of plundering and extraneous violence personal infringement, people can not effectively protect, and security performance is in urgent need of strengthening.
Summary of the invention
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and a kind of mobile phone portable power source with the anti-riot flak jacket function of reporting to the police is provided, can solve mobile phone needs the problem of charging at any time, can increase anti-riot flak jacket function, improving safety energy for the user again.
The technical solution adopted in the utility model is:
A kind of mobile phone portable power source with the anti-riot flak jacket function of reporting to the police, comprise battery supply and the power control circuit plate installed in mobile phone portable power source housing and the mobile phone portable power source housing, mobile phone portable power source housing is provided with handset port and power interface, handset port all is connected with the power control circuit plate with power interface, loud speaker and warning button also are installed on mobile phone portable power source housing, in mobile phone portable power source housing, warning circuit is installed also, warning circuit provides working power by battery, and warning circuit connects control by the warning button.
In the technique scheme, warning circuit is connected to form successively by multi-functional audio circuit, pre-amplification circuit, power amplifier, loud speaker.
Because the utility model has been set up warning circuit and loud speaker and their control button on the basis of prior art mobile phone portable power source; thereby increased warning function; greatly widened mobile phone portable power source function, the user can carry out self-protection when meeting the violence infringement.The utility model is reasonable in design, and is simple in structure, easy to carry, has power supply and anti-riot flak jacket function simultaneously, and security performance is good, is widely used.
