Abstract
A hearing aid includes an electronic assembly mounted in a cylindrical shell with the shell being mounted in an opening in a ear mold. The electronics assembly includes a printed circuit strip having thereon a speaker, a microphone and electronic components forming a signal processing circuit 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.
