Abstract: An electronic unit has a circuit board that is integrated into an injection molded circuit carrier. A hearing aid is provided with such an electronic unit. In order to reduce the complexity and size of an electronic unit with an injection molded circuit carrier and a circuit board, the circuit board is integrated into the injection molded circuit carrier by introducing the circuit board into the plastic mold such that the surface of a first side of the circuit board lies within the plastic mold and the surface of a second side of the circuit board is substantially flush with the surface of the plastic mold. At least one conductive track of the circuit board is electrically conductively connected to at least one conductive track of the injection molded circuit carrier.

Abstract: A rechargeable battery pack, or accumulator pack, for instance for a hearing instrument, has a minimal installation size and high energy density. The accumulator pack has at least one rechargeable battery cell, charging electronics, signal electronics, and signal contacts. An encapsulation protects against moisture and contamination. The signal electronics transforms an output voltage of the battery cell into a predetermined voltage, which is made available by two signal contacts outside of the encapsulation. The transformation of the voltage enables the battery systems to be used with various battery and/or cell voltages. Li-ion battery systems, which generally operate with 3.7 volts, can thus also be used in hearing instruments, which generally operate with an operating voltage of 1.2 volts. The encapsulation of the accumulator pack is particularly advantageous in this context of the higher voltages.
