    • A microphone-speaker assembly includes a housing, a microphone, a speaker, and a push-to-talk switch. The housing supports the speaker for movement between a first position in which the switch is not activated and a second position in which the switch is activated. The switch is located in a water resistant chamber along with a circuit board. The speaker moves toward the circuit board when it moves from the first position to the second position. A seal supports the speaker for movement between the first and second positions. A method of activating a microphone in a microphone-speaker assembly includes the steps of applying force to a speaker of the assembly, and moving the speaker thereby to activate the switch thereby to activate the microphone. The speaker moves relative to a push to talk switch, deforming a resilient membrane that helps to form a water resistant chamber in the assembly.
    • 麦克风扬声器组件包括壳体,麦克风,扬声器和按键通话开关。 壳体支撑扬声器用于在开关未被激活的第一位置和开关被激活的第二位置之间移动。 开关与电路板一起位于防水室内。 当扬声器从第一位置移动到第二位置时,扬声器向电路板移动。 密封件支撑扬声器以在第一和第二位置之间移动。 在麦克风 - 扬声器组件中激活麦克风的方法包括以下步骤:向组件的扬声器施加力,并且移动扬声器从而激活开关,从而激活麦克风。 扬声器相对于按键通话开关移动,使弹性膜变形,有助于在组件中形成防水室。

    • An arrangement used in a speaker designed to restrict movement of at least a portion of the speaker cone, to inhibit the speaker cone from deforming, completely flipping inside out and/or to inhibit sticking of the speaker cone to a frame of the speaker. In one arrangement, there is provided a speaker insert that is designed to be inserted at least partially between the frame and the cone of a speaker. The speaker insert includes a body having a front face and a rear face, a frame opening positioned at least closely adjacent to a center region of the body, and a plurality of gas openings spaced from the primary opening and spaced from a periphery edge of the body. In another and/or additional arrangement, the speaker includes a modified speaker frame.
    • 在扬声器中使用的布置,其设计成限制扬声器锥体的至少一部分的运动,以阻止扬声器锥体变形,完全翻转内部和/或阻止扬声器锥体与扬声器的框架的粘着。 在一种布置中,提供了一种设计成至少部分地插入在扬声器的框架和锥体之间的扬声器插入件。 扬声器插入件包括具有前表面和后表面的主体,至少紧邻主体的中心区域的框架开口,以及与主开口间隔开并与第一开口的外围边缘间隔开的多个气体开口 身体。 在另一种和/或另外的配置中,扬声器包括一个改进的扬声器框架。
