Reducing Intermodulation Distortion Effects in Hearable Devices - A simplified explanation of the abstract
This abstract first appeared for US patent application 18125615 titled 'Reducing Intermodulation Distortion Effects in Hearable Devices
- Simplified Explanation:**
This patent application describes methods and devices to reduce intermodulation distortion in hearable devices by using two speakers with different diaphragm configurations that offset distortion effects.
- Key Features and Innovation:**
- Apparatus includes two speakers with different diaphragm configurations to offset intermodulation distortion effects.
- First speaker has a forward roll surround while the second speaker has a reverse roll surround.
- Distortion effects at the diaphragms are substantially offset by each other at the aperture.
- Potential Applications:**
This technology can be applied in various hearable devices such as headphones, earbuds, hearing aids, and other audio devices where high-quality sound reproduction is essential.
- Problems Solved:**
This technology addresses the issue of intermodulation distortion in hearable devices, which can degrade sound quality and affect the listening experience of users.
- Benefits:**
- Improved sound quality in hearable devices.
- Enhanced listening experience for users.
- Reduction of intermodulation distortion effects.
- Commercial Applications:**
- "Innovative Speaker Technology for Enhanced Sound Quality in Hearable Devices"
- This technology can be utilized in the consumer electronics industry for the development of high-fidelity audio products.
- Prior Art:**
Readers can explore prior art related to speaker technology, audio signal processing, and intermodulation distortion reduction techniques in the field of acoustics and audio engineering.
- Frequently Updated Research:**
Researchers may find updated studies on speaker design, audio signal processing algorithms, and advancements in reducing distortion effects in audio devices.
- Questions about Hearable Device Speaker Technology:**
1. How does intermodulation distortion affect sound quality in hearable devices?
- Intermodulation distortion can cause unwanted artifacts and affect the fidelity of audio reproduction in hearable devices.
2. What are the key differences between forward roll and reverse roll surrounds in speakers?

Original Abstract Submitted
This document describes techniques and apparatuses directed at reducing intermodulation distortion effects in hearable devices. In aspects, an apparatus includes a first speaker and a second speaker disposed within a housing having an acoustic cavity adjacent to an aperture. The first speaker includes a first diaphragm facing the acoustic cavity and coupled to the housing by a forward roll surround. The second speaker includes a second diaphragm facing the acoustic cavity and coupled to the housing by a reverse roll surround. Intermodulation distortion effects that arise at the first diaphragm having the forward roll surround and the second diaphragm having the reverse roll surround are substantially offset by each other at the aperture.
