TODAY’S PATENT – THE HOOK FOR A HEARING AID
The Hook for a hearing aid was invented by Morten Jorgen and Mejner Olsen on the 10th of December 2013, bearing patent number US8605928B2.
The present invention is a hearing aid hook and the hearing aid utilizing the hook, which provides a sound passage for the sound emitted from the output device. The hook is composed of different parts made from materials with different mechanical properties. This provides a damping means for damping mechanical vibrations. The hook is designed to transition from the device’s housing to its sound tube and to provide a sound path for sound waves coming from the output transducer in the housing to travel to the sound tube, it has a distal part and a vibration-dampening part. The distal part is made of a first material, and the vibration-dampening part is made of a second material that includes an adhesive layer connecting the distal part to another part of the hearing aid. Because the first and second materials have different elastic properties, the second material acoustically separates the distal part from the other part, preventing acoustic energy from travelling between the two parts.
The objective behind this invention is to increase the efficiency of transmission of sound from output device via hook to the user.
