Modular electroacoustic instrument
First Claim
1. An electronic signal processing system for a hearing instrument comprising:
- a microphone section, having a bottom, shaped to enclose a microphone and signal processing circuitry, the bottom of the microphone section having a plurality of conducting contacts;
a battery section, connectable to said microphone section, including a casing for engaging the auditory canal and an integral battery, the casing having a vent through which oxygen is supplied to an electrode of the integral battery; and
a removable tab positioned between the conducting contacts of the bottom of the microphone section and the top of the casing of the battery section, the removable tab substantially sealing the vent and preventing electrical contact between the integral battery and the plurality of conducting contacts.

Abstract
An electronic signal processing system, including a microphone section and an integral battery, may be assembled with a receiver section to form a three section hearing-aid. The shape of the outer shell of an integral battery may approximate the shape of an ear canal when attached to the other two sections. An integral (sealed-in) battery with such an unusual shape may have a higher capacity battery than those of standard insertable/removable batteries. The integral battery (e.g. a zinc-air battery) may be tested for leakage before being assembled to the other sections of the hearing-aid. To preserve battery shelf-life a “pull” tab may be placed over vents in the integral battery. To activate the battery, the “pull” tab may be removed. Conducting strips may be formed on the “pull” tab permitting the circuits, battery and components of the hearing-aid to be tested after assembly. In addition, a rotating microphone section-may be used to shift between audio modes of the signal processing circuitry.
