[0027] Microphone Port Design Overview

[0028] Implementations disclosed herein provide means and apparatus for microphone port design for handheld devices or other electronic devices. A handheld device can be a handset, tablet computer, telephone, smart phone, portable electronic device, electronic organizer, and / or personal digital assistant (PDA). Handheld devices may be capable of communicating with other devices via cellular and / or other communication networks. The microphone port design can be used to reduce undesirable rubbing noise that occurs when the microphone port is completely covered by hands, fingers, skin, clothing, or other surfaces or materials. In one aspect, the microphone port can be placed in a long, narrow and shallow channel that cannot be easily fully covered by an average human finger. When the microphone port is placed within this channel, air vibrations can escape around the overlying finger, and into the surrounding atmosphere. As a result, a...

Abstract

The present invention discloses a microphone port design for a handheld device. The microphone port design includes an elongated channel disposed in a first surface of the handheld device. The microphone port is located within the channel to reduce unwanted noise caused by the buildup of air pressure around the opening of the microphone port due to the opening being covered by the user's finger.

Description

technical field [0001] The systems and devices disclosed herein relate generally to microphone ports, and more specifically to configurations of microphone ports that minimize noise generated by contact with the ports. Background technique [0002] Electronic devices may often be used in situations where a microphone is subject to momentary or continuous air flow or air pressure disturbances, such as "burst" pressure changes or wind noise. Under certain conditions, changes in air flow or pressure incident on the microphone can be so great that sound is picked up by the microphone and produces an undesirable noise signal that interferes with the use of the microphone and provides an unpleasant and distracting noise. During a phone call, for example, audible airflow noise may make sound emissions difficult to hear for the listener. [0003] In general, several types of omnidirectional microphones have been used in portable electronic devices. Although omnidirectional microp...
