Abstract
Abstract This heart novelty and relaxation device has a heart-shaped housing that contains a speaker and circuitry for producing a slow heartbeat sound which has a relaxing effect on a listener. The housing is assembled from two molded plastic conformal sides having integral complementary stanchions that mate to hold the sides together along a median plane. The circuitry is mounted on a board which also supports an on-off switch having a flat arm that pivots in the median plane. A portion of the switch arm projects unobtrusively from the housing through a slot at the interface between the sides to facilitate external control of the device.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
197 words
A heart novelty and relaxation device comprising: a molded plastic housing of heart shape, said housing having two conformal sides separated along a median plane and adapted for press-together assembly, a speaker within said housing, an electrical circuit within said housing for providing to said speaker a signal to simulate the sound of the human heartbeat at a slow pulse rate, an on-off switch for said circuit, said switch being mounted within said housing and having a flat control arm extending unobtrusively from said housing through a thin longitudinal slot formed along said median plane, and wherein said electrical circuit is mounted on a circuit board situated adjacent said median plane, said switch arm consisting of a flat strip of metal lying in said median plane and pivotally mounted to said circuit board by a conductive pivot member extending through said metal strip and said circuit board, said switch also having a spring metal contact fixedly mounted to said circuit board, said switch arm pivoting about said pivot member in said median plane into engagement with said spring metal contact to close said switch via an electrical path including said pivot member, said switch arm and contact.
Claim 2
Dependent Claim
197 words
A heart novelty and relaxation device comprising: a molded plastic housing of heart shape, said housing having two conformal sides separated along a median plane and adapted for press-together assembly, a speaker within said housing, an electrical circuit within said housing for providing to said speaker a signal to simulate the sound of the human heartbeat at a slow pulse rate, an on-off switch for said circuit, said switch being mounted within said housing and having a flat control arm extending unobtrusively from said housing through a thin longitudinal slot formed along said median plane, and wherein said electrical circuit is mounted on a circuit board situated adjacent said median plane, said switch arm consisting of a flat strip of metal lying in said median plane and pivotally mounted to said circuit board by a conductive pivot member extending through said metal strip and said circuit board, said switch also having a spring metal contact fixedly mounted to said circuit board, said switch arm pivoting about said pivot member in said median plane into engagement with said spring metal contact to close said switch via an electrical path including said pivot member, said switch arm and contact.
Claim 3
Dependent Claim
44 words
A heart novelty and relaxation device according to claim 1 wherein said two housing sides include integrally molded, complementary mating stanchions, the stanchions of one housing side being matingly received by the complementary stanchions of the other housing side to accomplish said snap-together assembly.
Claim 4
Dependent Claim
82 words
A heart novelty and relaxation device according to claim 2 wherein said electrical circuit comprises a free running multivibrator that produces a single rectangular wave signal causing said speaker to produce two sound beats per cycle, one at each transition of said rectangular wave signal, the duty cycle of said rectangular wave signal being selected so that the sound beats resemble both the systolic and diastolic components of a human heartbeat, at a pulse rate lower than about 72 beats per minute.
