Abstract
A baby monitor system that includes a parent unit and a baby unit that have a two-way radio frequency communications link established therebetween. The baby monitor system also includes a message storage mechanism that allows a care giver to record a soothing message for playback to the baby in response to activation of a play switch. Use of the recorded message allows the care giver to provide the baby with a soothing message even when the care giver is in an ambient noise environment, such as a shower, that could startle are irritate the baby.
Claims16
A baby monitor system comprising:
- a parent unit;
- and
- a baby unit;
- said parent unit including:
- a waterproof parent unit housing having a snap closure microphone cover and a waterproof speaker grating;
- a parent unit central processing circuit positioned within said waterproof parent unit housing that includes a radio frequency transmitter and receiver circuit including a parent unit antenna, an analog to digital microphone amplification circuit, a digital message memory, a digital to analog converter and a speaker drive circuit;
- a parent unit microphone in electrical connection with said parent unit central processing circuit;
- a waterproof volume control switch in electrical connection with said parent unit central processing circuit;
- a waterproof message record switch in electrical connection with said parent unit central processing circuit;
- a waterproof message playback switch in electrical connection with said parent unit central processing circuit;
- a waterproof direct talk switch in electrical connection with said parent unit central processing circuit;
- a waterproof on/off switch in electrical connection with said parent unit central processing circuit;
- and
- a parent unit speaker in electrical connection with
- said parent unit central processing circuit;
- said baby unit including:
- a baby unit housing including a baby unit speaker grating and a baby unit microphone grating;
- a baby unit central processing circuit including a radio frequency transmitter and receiver circuit including a baby unit antenna, an analog to digital microphone amplification circuit, a digital to analog converter and a speaker drive circuit;
- a baby unit microphone in electrical connection with said baby unit central processing circuit;
- a baby unit volume control switch in electrical connection with said baby unit central processing circuit;
- a baby unit on/off switch in electrical connection with said baby unit central processing circuit;
- and
- a baby unit speaker in electrical connection with said baby unit central processing circuit;
- said parent unit central processing circuit and said baby unit central processing circuit having a two way radio frequency communication link established therebetween;
- said parent unit central processing circuit being responsive to said waterproof message record switch in a manner to digitize a parent unit microphone signal from said parent unit microphone and store said digitized parent unit microphone signal in said digital message memory;
- said parent unit central processing circuit being responsive to said waterproof message playback switch in a manner to transmit a radio frequency signal corresponding to said digitized parent unit microphone signal in said digital message memory to said baby unit central processing circuit for playback on said a baby unit speaker;
- said parent unit central processing circuit being responsive to said waterproof direct talk switch in a manner to transmit a radio frequency signal corresponding to said parent unit microphone signal to said baby unit central processing circuit for playback on said a baby unit speaker.
