It is possible that other forms of wireless communications can be used such as ultrasonic, optical, and others. It is understood that the standards which can be used include past and present standards. It is also contemplated that future versions of these standards and new future standards may be employed without departing from the scope of the present subject matter.
In the embodiment of FIG. 17, a charger port 1717 is employed which activates a charging circuit 1708 to charge battery 1706. In one embodiment, the charger port 1717 is a mini USB connector. Other connectors may be employed without departing from the scope of the present subject matter. The battery 1706 powers controller 1702 and 1704 in various embodiments. Other devices may be powered by battery 1706 including, but not limited to microphone 1714, speaker 1718, and/or light 1716, for example. Such devices may also receive power from other components such as controller 1702, for example. Some embodiments employ a replaceable battery 1706 and do not require charging or a charger circuit 1708.
The embodiment of FIG. 17 also includes, optionally, specialized inputs such as a inputs for volume control 1712, 1713 which can be switches or potentiometers, and inputs for initiating or termination of use of the device, such as the talk input. Such switches provide the functionality of the wireless communications adaptor discussed herein, among other possible functionalities. The discussion above is referenced herein to include those functionalities.
The speaker 1718 can receive signals from the controller 1702. It is understood that the device 1700 can have a wireless module 1704 which supports reception, transmission, and combinations of reception and transmission.
In one application the present system provides a wireless interface to a user having a custom-fitted earmold adapted to receive signals from another wireless source. Such applications may include transmission of signals to that wireless source. The system can also support control signals between such devices to perform functions, including but not limited to, cellular telephone communications and reception of audio signals generally. In various embodiments the microphone gains and/or directionalities can be adjusted for user conditions. Thus, for example, in a crowded and noisy environment it may be desirable to reduce microphone gain for better reception of the user's voice as opposed to reception of room sounds and/or other noise.
Various forms of data can be communicated. For example, data such as voice data, streaming audio data, application data, and/or functional parameters, may be communicated with such a configuration. Other forms of data may be communicated without departing from the scope of the present subject matter.
Additionally, one of ordinary skill in the art will understand that, the systems shown and described herein can be implemented using software, hardware, and combinations of software and hardware. As such, the term “system” is intended to encompass software implementations, hardware implementations, and software and hardware implementations.
It is further understood that the principles set forth herein can be applied to a variety of hearing assistance devices, including, but not limited to occluding and non-occluding applications. Some types of hearing assistance devices which may benefit from the principles set forth herein include, but are not limited to, behind-the-ear devices, over-the-ear devices, on-the-ear devices, and in-the ear devices, such as in-the-canal and/or completely-in-the-canal hearing assistance devices. Other applications beyond those listed herein are contemplated as well.
It is to be understood that the above description is intended to be illustrative, and not restrictive. Thus, the scope of the present subject matter is determined by the appended claims and their legal equivalents.
