Picture Frame With Sound Producing Means

The present invention relates to a picture frame having sound producing means, and more particularly relates to a touch control switch for a picture frame for controlling the operation of a sound producing circuit assembly being installed in the picture frame.

A normal picture frame is simply a standing ornamental frame for holding a picture. Because it is a standing object, it is monotonous and less attractive. The present invention provides a picture frame with a sound generating circuit assembly so that the picture frame gives sound when it is touched. The present invention also provides a touch control circuit which controls the operation of the sound generating circuit assembly. According to the preferred embodiment of the present invention, the sound generating circuit assembly is fastened inside the back cover of the picture frame with its two opposite terminals respectively connected to two opposite metal contact pins. The metal contact pins are electrically connected by metal contact strips on the back board of the picture frame as the glass of the picture frame is pressed, and therefore the sound generating circuit assembly is triggered to produce sound.

FIG. 1 is an exploded view of a picture frame according to the preferred embodiment of the present invention;

FIG. 2 is an elevational view of the picture frame of FIG. 1;

FIG. 3 is a sectional view of the picture frame of FIG. 1 showing the circuit thereof opened;

FIG. 4 is similar to FIG. 3 but showing the circuit thereof closed; and

FIG. 5 shows the picture frame of FIG. 1 touched to sound.

Referring to FIG. 1, 2, and 3, a picture frame in accordance with the present invention is generally comprised of a frame body 1, a glass 2, a picture 3, a back board 4, a mounting plate 5, an open mounting frame 6, a battery set 7, a back cover 8, a speaker 9, and a sound generating circuit assembly 10. The frame body 1 is made of an open frame having a stepped picture mounting hole 11 in the center, which receives the glass 2 and the picture 3, and a plurality of screw holes 12 spaced around the stepped picture mounting hole 11. The open mounting frame 6 is fastened to the frame body 1 to retain the glass 2 and the picture 3 within the picture mounting hole 11 on the frame body 1 by threading screws 63 through respective screw holes 62 on the open mounting frame 6 into the screw holes 12 on the frame body 1 respectively. The open mounting frame 6 further comprises a plurality of back cover mounting holes 61 horizontally spaced around four sides thereof at a different elevation (relative to the screw holes 62 thereof) for mounting the back cover 8. The back cover 8 comprises a battery box 81, which receives the battery set 7, a plurality of horizontal projecting blocks 82 spaced around the inside wall thereof at locations corresponding to the horizontal back cover mounting holes 61, and a plurality of female screws 83 spaced on the inside around the four corners thereof. The mounting plate 5 comprises a plurality of screw holes 55 corresponding to the female screws 83 on the back cover 8, a plurality of retaining holes 53 spaced around the four corners thereof, opposite contact pins 51 disposed at two opposite locations, and a plurality of springs 52 raised from the back side thereof. The back board 4 comprises a plurality of hooks 42 at locations corresponding to the retaining holes 53 on the mounting plate 5, and two opposite metal contact strips 41 electrically connected together. The speaker 9 and the sound generating circuit assembly 10 are fastened within the back cover 8. After the speaker 9 and the sound generating circuit assembly 10 are installed in the back cover 8, the mounting plate 5 is fastened to the back cover 8 by threading screws 55 through the screw holes 55 on the mounting plate 5 into the female screws 83 on the back cover 8, and therefore the speaker 9 and the sound generating circuit assembly 10 are covered within the back cover 8 by the mounting plate 5. Then, the back board 4 is fastened to the mounting plate 5 by hooking the hooks 42 into the retaining holes 53 respectively permitting the back board 4 to be supported on the springs 52. When fastened, the opposite contact pins 51 respectively face the opposite metal contact strips 41 on the back board 4. Because of the effect of the springs 52, the opposite contact pins 51 are stopped from touching the opposite metal contact strips 41. Finally, the open mounting frame 6 is fastened to the back cover 8 by inserting the projecting blocks 82 into the back cover mounting holes 61. When the whole assembly is assembled, the metal contact strips 41, the contact pins 51, the speaker 9, the sound generating circuit assembly 10, and the battery set 7 are connected into a normal open circuit.

Referring to FIGS. 4 and 5, when the glass 2 is pressed with the hand, the springs 52 are compressed, causing the metal contact strips 41 to contact the contact pins 51 respectively, and therefore the circuit is closed. As the circuit is closed, the sound generating circuit assembly 10 is triggered to produce sound. The sound generating circuit assembly 10 may be variously embodied. For example, it may comprise a speech recording mechanism to record a speech such as "How are your?", "I miss you so much!", etc., for reproduction upon being triggered. The sound generating circuit assembly 10 may also be so made that it gives the correct time when triggered.
