Abstract:
A compact audio speaker assembly that fits into the ear canal without occluding the ear canal, thus allowing ambient sounds to be heard along with the audio source. The ear speaker is secured in the ear canal by a ribbon or wire like spring structure anchoring the speaker to the concha portion of the outer ear and typically pushing the speaker up against the top side of the ear canal, leaving a space for external sounds to bypass the speaker to the eardrum. The speaker may further include a connecting signal cable that passes over the ear and behind the ear to provide additional support for the speaker and strain relief for the signal cable. One embodiment may include a shell over the speaker connected to the wire like spring anchor and may include an ear wax screen. Two speakers may be configured for stereo listening.
