Preferably, the starter further includes the switching electricity for being series at loud speaker for circuit where cutting off loud speaker Road.

Using the above scheme, the setting of switching circuit so that after user is informed by loud speaker, user can be by right Switching circuit is operated, the alarm of mute speaker, highly practical, easy to operate.

Preferably, the power spring and conductor wire connecting pin are arranged with protective shell.

Using the above scheme, the setting of protective shell, one make the connection of power spring and conductor wire more secured, secondly So that the junction of power spring and conductor wire is safer, the case where avoiding leaking electricity, the safety coefficient of anti-theft circuit is improved.

Preferably, the cathode conductive film is equipped with the fixed column worn for power spring close to one end of conductor wire.

Using the above scheme, the setting of fixed column so that being more firmly mounted and stablizing for power spring avoids preventing fraudulent use of electricity In the course of work of road, the problem of power spring run-off the straight, so that the connection of power spring and conductor wire is more secured.

In conclusion the utility model has the advantages that：

Three can be installed on by the 1, setting of cathode conductive film, cathode conductive film, conductor wire according to different use occasions On door either on window or on valuables, there is relatively broad use occasion, and install it is simple, once stealer climbs over Either door or mobile valuables, conductor wire will fracture window, and loud speaker is alarmed；

2, the setting of power spring so that conductor wire can just fracture under certain effect power, and user is avoided accidentally to touch The problem of contacting conductor wire.
