摘要： A variable geometry battery compartment of an electronic communication device, such as a telephone test set, is readily reconfigurable by the user, so that different sized batteries can be used to power the circuitry of the device. For this purpose, a moveable battery contact wall is repositionable between spaced apart locations relative to a fixed battery contact wall. A charging switch controls the establishment of a charging path for rechargeable batteries, and can only be engaged when the moveable wall is positioned to accommodate longer sized rechargeable batteries. Changing the position of the moveable battery contact wall to accommodate shorter, non-rechargeable batteries, will prevent the charging switch from being engaged by an activating boss in a cover of the device, so that shorter non-rechargeable batteries cannot be placed in circuit with a battery charger.

摘要： Unwanted acoustic noise and environmental degradation associated with the use of a highly sensitive microphone in a telephone test set are eliminated by a microphone-integrated keypad laminate architecture, in which a microphone is snugly captured within a microphone holder molded into a pliable keypad unit and its leads sealed against the environment and case vibration. The keypad unit is supported by a keypad support structure adjacent to the test set's keypad face, so that the microphone holder is retained adjacent to an acoustic coupling port, and the keypad's keys are accessible by way of keypad apertures in the keypad face. A printed circuit board urges the keypad unit into engagement with the keypad support structure. The keypad unit and the printed circuit board have sealed aperture arrangements through which electrical leads of the microphone pass for connection to the circuit board.
摘要翻译：通过麦克风集成的键盘层叠结构消除了在电话测试装置中与使用高灵敏度麦克风相关联的不期望的声学噪声和环境退化，其中将麦克风紧密地捕获在模制成柔性键盘单元的麦克风支架内，并且其麦克风引线密封，防止环境振动。键盘单元由与测试仪的键盘面相邻的键盘支撑结构支持，使得麦克风保持器保持在声耦合端口附近，并且键盘的键可通过键盘面板中的键盘孔进行访问。印刷电路板促使键盘单元与键盘支撑结构接合。键盘单元和印刷电路板具有密封孔布置，麦克风的电引线通过该孔布置用于连接到电路板。
