    • A hearing instrument may include an enclosure adapted for behind-the-ear placement that houses a microphone for converting an acoustical input signal to an electrical signal and a sound processing circuit for processing the electrical signal; an earpiece adapted for in-the-canal placement that includes a receiver for converting the processed electrical signal to an acoustical output signal; a replaceable battery housed in the enclosure for powering the microphone, sound processing circuit and receiver; and an electrical cable extending from the enclosure that electrically couples the processed electrical signal from the sound processing circuit to the receiver. The enclosure includes a top portion and a bottom portion. The top portion and the bottom portion pivot about a hinge point at one end of the enclosure to open and closed positions. In the open position, the battery is accessible for replacement. A latch mechanism at the other end of the enclosure secures the top portion to the bottom portion in the closed position. The bottom portion may be detached from the top portion and may be replaced by the user.
    • 助听器可以包括适于耳后放置的外壳,其容纳用于将声输入信号转换为电信号的麦克风和用于处理电信号的声音处理电路; 用于管道内放置的耳机,其包括用于将经处理的电信号转换为声输出信号的接收器; 容纳在外壳中的可替换电池为麦克风,声音处理电路和接收器供电; 以及从外壳延伸的电缆,其将经处理的电信号从声音处理电路电耦合到接收器。 外壳包括顶部和底部。 顶部部分和底部部分围绕围绕壳体的一端处的铰链点枢转到打开和关闭位置。 在打开位置,电池可以更换。 在外壳的另一端处的闩锁机构将封闭位置的顶部固定到底部。 底部可以从顶部分离,并且可以由使用者代替。
