Problems solved by technology

In such systems, the bias consumed a significant amount of energy in the transmitted signal.
Unfortunately, the use of a sliding bias, while reducing the amount of energy required for the bias, does not eliminate the need for a bias signal, which consumes energy, potentially resulting in a shorter battery life or the need for a larger battery.
Further, the use of a sliding bias may result in sound artifacts which are audible to the hearing aid wearer.
This arrangement could be disadvantageous because the output of the medial ear canal assembly was subject to change, by, for

Embodiment Construction

[0021]FIG. 1 is a block diagram of a smartlens system 30 according to one embodiment of the present invention, including lateral ear canal assembly 12 (which may also be referred to as a light tip or eartip in some embodiments) and medial ear canal assembly 100 (which may also be referred to as a tympanic lens or tympanic lens transducer in some embodiments).

[0022]In the embodiment of FIG. 1, lateral ear canal assembly 12 includes a plurality of microphones 810 which are connected through pre-amplifiers 820 to analog to digital (A to D) converters 830. Analog to digital converters 830 may be connected to digital signal processor 840. The output of digital signal processor 840 may be connected to a circuit for modulating the output, such as, for example, pulse density modulator 850. In the embodiment of the invention, the output of pulse density modulator 850 may be connected to radio frequency (RF) modulator 860. The output of RF modulator 860 may be connected to power amplifier 870...

Abstract

The present invention is directed to a hearing aid which includes a lateral ear canal assembly and a medial ear canal assembly. In embodiments of the invention the medial ear canal assembly may include smart circuitry adapted to control parameters and outputs of the medial ear canal assembly. In embodiments of the invention various methods and circuitry are described, wherein the methods and circuitry are adapted to improve the performance and efficiency of the hearing aid.

Description

CROSS-REFERENCE[0001]This application claims priority under 35 U.S.C. § 120 to U.S. Provisional Application Ser. No. 62 / 385,914, filed Sep. 9, 2016, which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]In contact hearing aid systems, the system, including a contact hearing device, an ear tip and an audio processor, is employed to enhance the hearing of a user. Depending upon the contact hearing aid, the system may also include an external communication device, such as a cellular phone, which communicates with the audio processor. An example of such system is the Earlens Light Driven Hearing Aid manufactured by Earlens Corporation. The Earlens hearing-aid transmits an audio signal by laser to a tympanic membrane transducer which is placed on an ear drum of a user. In such systems, it may be beneficial to add smart components to the contact hearing device in order to improve the overall function and / or efficiency of the system. It may also be bene...
