Sound provider adapter to cancel out noise
View Patent ↗A sound provider for providing sound to a person's ear includes one or more terminals for receiving a first electrical signal and a first sound emitter operatively connected to the one or more terminals for outputting a sound corresponding to the first electrical signal. The sound provider also includes a sound receiver for receiving sound and outputting a corresponding, second, electrical signal, and a second sound emitter operatively connected to the sound receiver for outputting a sound corresponding to the second electrical signal.
1. A sound provider for providing sound to a person's ear, the provider comprising:
one or more terminals for receiving a first electrical signal associated with a desired sound;
a first sound emitter operatively connected to the one or more terminals for outputting a sound corresponding to the first electrical signal;
a sound receiver for receiving only an undesirable sound and outputting a corresponding, second, electrical signal, and
a second sound emitter operatively connected to the sound receiver for outputting a noise cancellation sound corresponding to the second electrical signal to cancel the undesirable sound.
2. A sound provider according to claim 1 , further comprising a housing, the first and second sound emitters being positioned so as to output the sound from the housing, and the sound receiver being positioned so as to receive sound from a vicinity of the housing.
3. A sound provider according to claim 2 , wherein the housing has a first part and a second part, the first part being adapted to face the ear canal of the person and the second part being adapted to face the surroundings of the person, the first part comprising a sound output for outputting the sound from the first and second sound emitters, and the second part comprising an opening for receiving sound for reception of the sound receiver.
4. A sound provider according to claim 2 , wherein the housing has a first part and a second part, the first part being adapted to face the ear canal of the person and the second part being adapted to face the surroundings of the person, the first part comprising a sound output for outputting the sound from the first and second sound emitters and an opening for receiving sound for reception of the sound receiver.
5. A sound provider according to claim 1 , further comprising:
a circuit operatively connected to the sound receiver for providing the second electrical signal as a signal with a phase opposite to a phase of the undesired sound.
6. The sound provider according to claim 1 , wherein the one or more terminals are engagable with a cable.
7. The sound provider according to claim 1 , wherein the one or more terminals are engagable with a wireless device outputting the first electrical signal.
8. A method of providing filtered sound to a person's ear, the method comprising:
receiving a first electrical signal associated with a desired sound via a terminal;
outputting a sound corresponding to the first electrical signal via a first sound emitter;
receiving only an undesirable sound via a sound receiver;
outputting a corresponding, second, electrical signal to the undesirable sound; and
outputting a noise cancellation sound via a second sound emitter corresponding to the second electrical signal to cancel the undesirable sound.
