A housing having a port for reducing wind-induced noise in a communication device. The housing includes a first channel, a second channel, and a ridge between the first and second channels. The housing further includes a tunnel extending through the ridge, which tunnel connects the first and second channels. The housing further includes a microphone port beneath the ridge, which microphone port is connected to the tunnel and connects the tunnel to a microphone cavity in the housing.

Slim-tunnel wind port for a communication device

A method and apparatus for receiving and playing a signal in a radio receiver to suppress microphonic feedback are provided by alternately pitch shifting a received audio signal. The pitch of the received audio signal is alternately shifted up and then down, repeatedly over successive intervals of the audio signal, to produce a pitch swing signal which is then played over a speaker. The alternating pitch shifting prevents the buildup of regenerative feedback normally caused by acoustic vibrations coupling into the radio receiver.

Method and apparatus for receiving and playing a signal in a radio receiver

A portable full duplex communication device () is provided with improved acoustic porting () by providing an earpiece enclosure () within the housing () of device. The earpiece enclosure () includes an array of micro-ports () formed to provide optimal low frequency response and echo performance without the use of external acoustical leak ports to the housing.

Acoustic porting for a portable communication device

A method for maintaining transmit audio quality under harsh environmental conditions, the method includes receiving audio signals into a microphone of a portable communication device and determining at least one parameter associated with the received audio signals. In accordance with an embodiment, the at least one parameter is compared with a received audio parameter threshold. When the at least one parameter falls outside of the received audio parameter threshold, the audio routing is switched from the microphone to the loudspeaker. Subsequent communication may revert back to the microphone or remain at the loudspeaker depending on monitored audio conditions.
