A transducer comprising a pair of spaced magnets at least partially forming a tunnel having a central axis. A coil having a first and a second side wall and an upper and a lower wall at least partially forms the tunnel. A reed having a central portion extends through the tunnel. The reed has a stationary end, a deflection end, and a tip portion which lies at least partially between the magnets, wherein the reed is mounted for deflection towards or away from the respective magnets.

Electroacoustic transducer with resistance to shock-waves

A system and method for assisting listening wherein an integrated circuit selects one or more audio sources from among a plurality audio sources to be presented to a signal processing circuit. Selection of the audio source can be automatically executed in response to detection of an external magnetic field, such as from a telephone handset, or manually controlled by a user input.

System and method for facilitating listening

Electro-acoustic transducer with resistance to shock-waves

The present invention relates to a hearing aid receiver (10) having a coil (12) with a tunnel (14) therethrough, a magnetic structure (16) having a central magnetic gap (18), an armature (20), and a fluid (30, 32) with a viscosity greater than air to provide shock protection to the receiver (10). The tunnel (14) and the magnetic gap (18) collectively form an armature aperture (28). The armature (20) extends through the armature aperture (28). The fluid (30, 32) lies within the armature aperture (28).
