Description

Built-in warning device mobile phone

Technical field

The utility model relates to a kind of Communication Equipment, particularly a kind of built-in warning device mobile phone that can send alarm signal automatically.

Background technology

Mobile phone is current wireless telecommunications equipment commonly used, provide convenience for people exchange information, but it has communication aspect function, does not possess automatic warning function; Common alarm such as theft-proof door bell, anti-theft device for vehicle etc. though all have the warning effect, can send caution sound, can't be to master alarm at a distance, disguised poor, the robber can find in the relatively shorter time, thereby escapes or take way to crack; Though the radio alarming device is disguised relatively good, generally have independently emission and receiving system, structure more complicated, cost are relatively more expensive, and domestic consumer holds and dares not accept.Thereby be difficult to apply.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved built-in warning device mobile phone is provided, and communication function and detectors are combined, and realizes a tractor serves several purposes.

The purpose of this utility model can realize by following technical measures: be equiped with warning device in the body of this mobile phone, warning device includes control switch, vibration sensor, time intermittent duty relay, control switch, vibration sensor, time intermittent duty relay series connection mobile phone battery joint, the contact of time intermittent duty relay connects the talk key line of mobile phone machine chip, with the talk key switch in parallel, the contact of this group time intermittent duty relay is a normally opened contact.In actual applications, disconnect control switch, mobile phone is as usual as communication tool, connect control switch, mobile phone is made alarm, preestablishes to redial the alarm call number on mobile phone, is placed on then than the shelter, when mobile phone is subjected to vibration effect, vibration sensor is connected, and provides power supply to the time intermittent duty relay, the talk key line of time intermittent duty relay intermittent connectivity mobile phone machine chip, mobile phone redials warning automatically, notifies owner to meet the robber.

Of the present utility model reasonable in design, in mobile phone, made up warning device, realize a tractor serves several purposes, wide application, practical, and simple in structure, it is few, easy to use that the product manufacturing increases cost, helps protecting people's property safety and social stability.
