Abstract
The disclosure recites a feedback system and method for adjusting output sounds generated by a communication device. The feedback system comprises: a transducer; a microphone; and an enclosure for the communication device defining a first location for the placement of the transducer, a second location for the placement of the microphone adjacent to the transducer, a first port connecting the first location to a cavity located on a top side of the enclosure, a second port connecting the second location to the cavity. For the system, the first port connects to the cavity beside the second port.
Claims16
A feedback system for output sounds generated by a communication device, comprising:
- a speaker;
- a microphone;
- an enclosure for the communication device defining a first location for the placement of the speaker, a second location for the placement of the microphone, a first port connecting the first location to a cavity located on a top side of the enclosure, a second port connecting the second location to the cavity,
- the cavity comprising:
- a bottom;
- sidewalls inwardly extending from an external face of the enclosure to the bottom;
- and an access extending across the external face, and between the sidewalls, the cavity having a same cross-sectional shape from the access to the bottom, the first port extending from the bottom of the cavity to the speaker, the second port extending from the bottom of the cavity to the microphone, and respective openings of each of the first port and the second port adjacent to each other in the bottom of the cavity;
- and,
- a processor;
- and a memory device;
- the processor configured to:
- measure input signals detected by the microphone;
- and
- when the input signals are determined to be greater than a threshold, decrease a current output signal.
The feedback system as claimed in claim wherein the first port has:
- a height of between approximately 1 mm and 4 mm;
- and
- a width of between approximately 2 mm and 15 mm.
A method of adjusting output sounds generated by a communication device, comprising:
- measuring input signals detected by a microphone located in an enclosure for the communication device defining a first location for the placement of a speaker, a second location for the placement of the microphone adjacent to the speaker, a first port connecting the first location to a cavity located on a top side of the enclosure, and a second port connecting the second location to the cavity, the cavity comprising:
- a bottom;
- sidewalls inwardly extending from an external face of the enclosure to the bottom;
- and an access extending across the external face, and between the sidewalls, the cavity having a same cross-sectional shape from the access to the bottom, the first port extending from the bottom of the cavity to the speaker, the second port extending from the bottom of the cavity to the microphone, and respective openings of each of the first port and the second port adjacent to each other in the bottom of the cavity;
- and
- when the input signals are greater than a threshold, decreasing a current signal output.
A non-transitory computer-readable medium storing a computer program, wherein execution of the computer program is for adjusting output sounds generated by a communication device:
- measuring input signals detected by a microphone located in an enclosure for the communication device defining a first location for the placement of a speaker, a second location for the placement of the microphone adjacent to the speaker, a first port connecting the first location to a cavity located on a top side of the enclosure, and a second port connecting the second location to the cavity, the cavity comprising:
- a bottom;
- sidewalls inwardly extending from an external face of the enclosure to the bottom;
- and an access extending across the external face, and between the sidewalls, the cavity having a same cross-sectional shape from the access to the bottom, the first port extending from the bottom of the cavity to the speaker, the second port extending from the bottom of the cavity to the microphone, and respective openings of each of the first port and the second port adjacent to each other in the bottom of the cavity;
- and
- when the input signals are greater than a threshold, decreasing a current signal output.
