First Claim
Patent Images
1. A canal hearing device comprising:
- a housing configured to accommodate a battery cell at least partially within, the housing comprising an elongate sound channel configured to receive an incoming sound from a sound channel inlet and provide a frequency-shaped sound output at a sound channel outlet, wherein a height of the elongate sound channel is less than a height of the battery cell along an entire length of the of the elongate sound channel, and wherein the frequency-shaped sound output provides at least 3 dB of gain at a frequency within the range of 3-6 kHz; and
a microphone;
a speaker for transmitting sound to the eardrum; and
a sound port acoustically coupling the frequency-shaped sound output to the microphone.

Abstract
Examples of canal hearing devices including a lateral section having a frequency shaping sound port system are disclosed. A lateral section includes an elongate sound channel for receiving an incoming sound and producing a frequency-shaped sound output. The hearing device includes a microphone, a speaker for transmitting sound to the eardrum, and a sound port to receive the frequency-shaped sound output from the elongate sound channel and provide a pathway for the frequency-shaped sound output to reach the microphone.
