Description

WIRELESS SYSTEM FOR HEARING COMMUNICATION DEVICES
PROVIDING WIRELESS STEREO RECEPTION MODES
Field of the Invention This application relates generally to hearing communication devices, and more particularly to a wireless system for hearing communication devices providing wireless stereo reception modes.

Background Modern hearing communication devices that offer stereo reception typically require a wire between the left and right devices. For example, wireless stereo headsets generally include a stereo receiver and a wired connection to feed both the left and right speakers with the stereo connection. Such devices are not readily applied to other hearing communication devices, such as hearing aids. This is in part because wires are inconvenient, prone to breakage and can be less aesthetically pleasing to users who wish to conceal or downplay their use of hearing aids or other hearing communication devices.
Thus, there is a need in the art for an inconspicuous, robust, and elegant system for communicating stereo information to a wearer of hearing communication devices. The system should be convenient to use and to manufacture.

Summary This application addresses the foregoing needs in the art and other needs not discussed herein. The various embodiments described herein relate to wireless systems for hearing communication devices providing wireless stereo reception modes.

The present subject matter relates to the wireless stereo reception of first and second audio information by hearing communication devices. One type of device which may employ the present subject matter is a hearing aid. Various forms and protocols of signal transmission are employed in varying embodiments. The present subject matter includes various communication modes such as eavesdropping modes and relaying modes..
This Summary is an overview of some of the teachings of the present application and not intended to be an exclusive or exhaustive treatment of the present subject matter. Further details about the present subject matter are found in the detailed description and appended claims.

Brief Description of the Drawings Various embodiments are illustrated by way of example in the figures of the accompanying drawings.
FIG. 1 shows one system using wireless devices in a direct communication mode according to one embodiment of the present subject matter.
FIG. 2 shows one application using wireless devices in an eavesdropping communication mode according to one embodiment of the present subject matter.
FIG. 3 shows one application using wireless devices in a relaying communication mode according to one embodiment of the present subject matter.
Detailed Description In the following detailed description specific details are set forth to generally demonstrate various embodiments of the invention and to allow one of skill in the art to make and use the invention in its various forms. Thus, the following detailed description is not intended to provide an exclusive or exhaustive treatment of the present subject matter.
It should be noted that references to "an", "one", or "various" embodiments in this disclosure are not necessarily to the same embodiment, and such references contemplate more than one embodiment.
FIG. 1 shows one system 100 using wireless devices in a direct communication mode with a remote source 102 according to one embodiment of the present subject matter. Remote source 102 transmits signals 105 to the first hearing communication device 104 including first audio information. Remote source 102 also transmits signals 109 to the second hearing communication device 108 including second audio information. In this embodiment, the first hearing communication device 104 does not have a wireless connection to the second hearing communication device 108 for transmitting stereo information from the first hearing communication device 104 to the second hearing communication device 108. Thus, the first audio information is wirelessly received by the first hearing communication device 104 and played to a first ear of the wearer and the second audio information is wirelessly received by the second hearing communication device 108 and played to the second ear of the wearer.
The system in various embodiments can also support eavesdropping modes.
For example, as shown in FIG. 2, in system 200 remote source 202 is in communications with first hearing communication device 204 via signals 205.
Second hearing communication device 208 can "listen in" on communications from remote source 202 using a mode that is different than the mode used by the first hearing communication device 204. For instance, it is possible that second hearing communication device 208 receives signals 210, but does not control, for example, handshaking with remote source 202 to the same extent as first communication device 204. Other eavesdropping modes can be employed without departing from the scope of the present subject matter.
FIG. 3 depicts one embodiment where a relaying mode is exnployed to communicate wirelessly between the first hearing communication device 304 and the second hearing communication device 308. In this embodiment, first and second audio information is sent over signal 305 to the first hearing communication device 304. The second audio information is then relayed to the second hearing communication device 308 via relay signal 311. Such relay may be performed using different frequencies, different communication modes and with different data rates, for different implementations if desired. In one embodiment, the first hearing communication device 304 may demodulate and decode stereo information and encode and relay the channel bound for the instrument on or in the other ear.
In various embodiments, the communications can be made using similar transmissions to the primary transmission. In various embodiments, the communications can be maded using a different method than that of the primary transmission. In various embodiments, the signals 305 and 311 are unidirectional. In various embodiments, the signals 305 and 311 are bidirectional. In various embodiments, the signals and 311 are programmably combinations of unidirectional and/or bidirectional.
Thus, the system 300 is highly programmable to adapt to a number of communication requirements and applications. In one embodiment, relay signal is a substantially magnetically coupled or near field communication link. In one embodiment, a telecoil is employed to receive the relay signal 311. In one embodiment, a magnetic sensor is used to receive the relay signal 311. In one embodiment, relay signal 311 is a radio frequency or far field communication link.
Other communication links, such as infrared and ultrasonic may be employed in various applications.
In the various embodiments and applications provided herein, different communications electronics are used by the systems (e.g., 100, 200, 300) to provide different communication modes for the stereo information. For example, in one embodiment a first channel and a second channel are employed to communicate the stereo information to the first and second ears, respectively. In one embodiment, the electronics includes frequency division multiplexed communications electronics. In one embodiment, the electronics includes time division multiplexed communications electronics. In one embodiment, the electronics includes code division multiplexed communications electronics. In one embodiment, the electronics includes packetized communications electronics. In one embodiment, the electronics includes analog communications electronics. In one embodiment, the electronics includes frequency modulated communications electronics. In one embodiment, the electronics includes single sideband communications electronics.
In one embodiment, the electronics includes amplitude modulated communications electronics. In one embod'unent, the electronics includes phase modulated communications electronics. Other modulation and communications embodiments are within the scope of the present subject matter and those examples provided herein are intended to demonstrate the flexibility and adaptability of the present subject matter.
The systems (e.g., 100, 200, and 300) invarious embodiments can also support communications modes where the first audio information and the second audio information are the same or substantially the same audio information.
In various embodiments, the remote source (e.g., 102, 202, and 302) supports one or more communication protocols. In various embodiments, communications of far field signals are supported. Some embodiments employ 2.4 GHz communications. In various embodiments the wireless communications can include standard or nonstandard communications.
