ACOUSTIC COLLECTION SYSTEM FOR HANDHELD ELECTRONIC DEVICES

摘要

An acoustic collection system for handheld electronic devices is disclosed having a fitted casing with a chestpiece, and a passageway for conducting sound from the chestpiece to a microphone. In one embodiment, the configuration of the passageway can be actively varied by the user to selectively transmit frequencies of interest to the device. In another embodiment, materials with different sound propagation properties may be used to augment or dampen sound within the passage. In another embodiment, a microphone may be placed within the passageway and its position therein varied by the user.

主权项

1. An acoustic collection tool for a handheld electronic device comprising:
a casing mountable to said handheld electronic device; a chestpiece attachable to said casing, said chestpiece having an aperture for carrying sound to a hole on the chestpiece; a hollow passage mounted to said casing for transmitting sound to a microphone, said hollow passage having a first opening and a second opening, and said hollow passage having an inner wall; wherein said hole of said chestpiece is configured to mate with either of said first opening and said second openings; and wherein mating said hole with said first opening will cause a distance through said hollow passage between said hole and said microphone to be longer than if said hole is mated to said second opening.
