Abstract

A sound producing control switch for a picture-frame, includes a control circuit which is fastened in the back cover of a picture-frame. The control circuit includes a music IC, a battery power supply and a speaker, a conductive strip fastened in the picture-frame at the inside, two leaf springs mounted on the window glass of the picture-frame, which leaf springs are respectively connected to the two opposite terminals of the control circuit and constantly forced to contact the conductive strip by two spring means. The control circuit is triggered to produce the sound of "I Love You" twice when the picture-frame is touched to produce a short circuit signal. The spring means automatically force the leaf springs to contact the conductive strip immediately after the leaf springs have been forced to disconnect from the conductive strip.

Claims

1. A sound producing control switch for a picture-frame having a back and a front, comprising:

a picture-frame body having defined therein a show window, said show window having a back and a front;

a conductive strip made from a thin, flat copper strip adhered to the back of said show window at an upper position;

a sheet of glass covering said show window;

two leaf springs clamped on said sheet of glass and disposed in contact with said conductive strip;

a back cover covering the back of said picture-frame body;

two springs means respectively secured to said two leaf springs and positioned against said back cover;

a control circuit fastened in said back cover, the control circuit including two opposite terminals electrically connected to said two leaf springs, a battery power supply, a music IC and a speaker;

wherein said conductive strip, show window, and leaf springs are arranged such that movement of said picture-frame body causes said two leaf springs to temporarily disconnect from said conductive strip, triggering said control circuit to produce a sound through said speaker, and wherein said spring means is arranged to automatically force said two leaf springs to contact said conductive strip immediately after said two leaf springs have been caused to disconnect from said conductive strip to prevent said sound from repeating.
