Abstract
An apparatus including a microphone; a speaker including at least one vibrating element and at least one movable section, where the at least one vibrating element is configured to at least partially move the at least one movable section to generate sound waves from the at least one movable section; and at least one vibration dampening member between the microphone and the at least one movable section, where the at least one vibration dampening member is suitably positioned in a path of vibration transmission between the at least one vibrating element and the microphone, where the at least one vibration dampening member is configured to absorb vibrations when the movable section is actuated by the at least one vibrating element.
