Abstract:

A method of converting electrical signals into mechanical vibration by means of a transducer in the human ear, an ear canal transducer and a headset wherein a sensation of hearing is achieved by exciting the tissue of the ear canal directly with said transducer, whereby the vibrations propagate to the tympanic membrane and into the human sound sensing organs.

FIELD OF THE INVENTION

The present invention relates to a method of converting electrical signals into mechanical vibration in an ear canal. The present invention also relates to a method of converting mechanical vibration into electric signals in an ear canal.

The present invention further relates to an ear canal transducer. The present invention further relates to a headset for electronic devices, such as mobile phones, with an ear canal transducer suitable for a connection to an electronic device.

BACKGROUND OF THE INVENTION

Headsets are used as loudspeakers to listen to sound produced by a wide variety of electronic audio devices. Examples of such devices that are used with a headset are a broadcast radio receiver, a CD Player, an MP3 player, two way radio, mobile phone and television receiver. A headset can be connected to the audio device by a cable or with a wireless connection such as Bluetooth, DECT, or another wireless technology. Wireless connections can be used to free the user from being tied directly to the audio device by a cable. A headset typically includes an audio transducer worn close to the ear. In case the headset provides audio for both ears, the headset has a pair of transducers, one for each ear. The headset also includes any additional electronics required to connect the headset to the audio device the user wishes to listen to, and optionally, additional user interface (UI) features such as a volume control. In case of a wireless headset, a battery, a solar cell or another power source i ...
