Embodiments relate to an audio system configured to provide enhancement of low audio frequencies. The audio system includes a tissue transducer and a speaker coupled to the tissue transducer. The tissue transducer is configured to be coupled to a tissue of a user (e.g., pinna of a user's ear). The speaker includes a diaphragm having a first surface and a second surface that is opposite the first surface. The first surface is configured to generate a first set of airborne acoustic pressure waves, and the second surface is configured to generate a backpressure. The tissue transducer is driven by the backpressure to vibrate the tissue to form a second set of acoustic pressure waves. The first set of airborne acoustic pressure waves and the second set of acoustic pressure waves together form audio content that is presented to the user.

An ear-wearable device is described that includes a plurality of modules that mate together forming a physical outer shell of the ear-wearable device. Each module from the plurality of modules is associated with a different, corresponding feature of the ear-wearable device and each module from the plurality of modules includes a respective physical portion that comprises a different, corresponding part of the outer shell. In addition, each module from the plurality of modules shares a physical interface with at least one other module from the plurality of modules.

A hearing prosthesis circuit includes a power source, a first amplifier coupled to the power source, and a second amplifier coupled to the power source. The circuit also includes a stimulation component coupled to the first amplifier and the second amplifier. The stimulation component is configured to provide an output in accordance with an electrical signal that includes audio data. Further, the circuit includes a controller coupled to the first amplifier and the second amplifier. The controller is operable in accordance with a first operational setting to use the first amplifier to provide the electrical signal to the stimulation component and the controller is also operable in accordance with a second operational setting to use the second amplifier to provide the electrical signal to the stimulation component. Generally, the first amplifier provides greater signal amplification of the audio data than the second amplifier.

Low-cost hearing aid platforms that are customizable for specific user needs are disclosed. An exemplary hearing aid platform includes an electret microphone, an amplifier, a capacitor, a printable circuit board (PCB), an audio output, and a housing for the components. The hearing aid platform may comprise customizable gain settings and safety features such as automatic gain control. In some embodiments, the hearing aid platform may connect to headphones. In some embodiments, the hearing aid platform may connect to a bone transducer. Devices described herein also may include housings that are customizable for a user's needs and/or personality.

A method for the identification of a receiver belonging to one of a plurality of receiver types in a hearing aid system includes supplying an electrical input signal to the receiver for sound output. The input signal is a primary signal, and a secondary signal that depends on the input signal is generated on the basis of the sound output. The secondary signal is captured by a sensor which generates an electrical sensor signal depending on the secondary signal. A phase measurement is furthermore carried out by determining a phase difference between the input signal and the sensor signal. The receiver is then identified by assigning the receiver to one of the plurality of receiver types on the basis of the phase difference. A corresponding hearing aid system and an receiver set are also provided.
