New Patent Solves Earbud Sound Leakage Problem

In the world of earbuds, sound leakage has been a persistent issue that affects the user experience. However, a recently published patent by Merry Electronics (Shenzhen) Co. offers a promising solution to this problem. Patent number US11917353B2 introduces a groundbreaking earbud design that aims to eliminate sound leakage and enhance the overall audio quality.

The core problem addressed by this patent is the absence of components between the diaphragm and the sound outlet hole in conventional earbuds. This results in direct output sound and smaller sound damping. On the other hand, the presence of a speaker driver basin frame and a rear cavity creates larger sound damping, leading to a mismatch between the sound volume and the phase of the sound outlet hole and the sound tuning hole. This mismatch causes sound leakage, particularly in certain frequency bands.

To overcome these challenges, the patent presents an innovative earbud design. The key feature of this new design is the inclusion of a partition within the earbud. This partition separates the inside of the earbud into two distinct areas. Crucially, the partition incorporates tiny holes that allow sound to pass through while maintaining optimal acoustic mass and resistance.

By integrating the partition with large and long holes, this new earbud design achieves a delicate balance between damping and acoustic mass sensitivity. This equilibrium ensures that the earbud produces the same volume while producing opposite sound directions at the sound outlet hole and the sound tuning hole, resulting in improved directivity across the whole frequency range.

If this patent becomes a reality, the world of earbuds will undergo a significant transformation. People can finally enjoy their music or take calls without worrying about sound leakage. With these new earbuds, it will be possible to experience enhanced audio quality and immersion, allowing users to better appreciate their favorite songs or podcasts.

Imagine listening to your favorite band on a crowded subway without disturbing fellow passengers. Or engaging in a phone conversation in a noisy café without any concerns about privacy. This patent opens up a world of possibilities that will revolutionize how we experience audio in our everyday lives.

It is important to note that this is a patent, and its appearance in the market is not guaranteed. While the technology showcased in this patent holds immense potential, further development and commercialization processes need to take place before it becomes a reality.

In conclusion, Merry Electronics' patent on an innovative earbud design presents a promising solution to the long-standing issue of sound leakage. By introducing a partition with strategically placed holes, this design aims to enhance audio quality and eradicate sound leakage. If this invention becomes a reality, it has the potential to revolutionize the way we enjoy audio, providing a more immersive and private experience for users. However, only time will tell if this patent will make its way into the market and transform the future of earbuds.

P.S. Please note that this article is based on a recently published patent (US11917353B2) by Merry Electronics (Shenzhen) Co. It is important to highlight that there is no certainty regarding the availability or implementation of this technology in the market.
