DISPOSABLE HEARING AID

摘要

A hearing aid (10) includes an electronic assembly (12) mounted in a cylindrical shell (14) with the shell (14) being mounted in an opening in an ear mold (16). The electronics assembly (12) inclludes a printed circuit strip (26) having thereon a speaker (22), a microphone (18) and electronic components forming a signal processing circuit (20) for amplifying the sound. The ear mold is of a soft, durable and compliant material so that it will fit tightly in the ear of a user. The hearing aid is of optimum design having a minimum number of components and is easy to assemble on an automatic basis. This provides a hearing aid which is relatively inexpensive so as to be disposable.
