    摘要: There are provided an electroacoustic diaphragm and an electroacoustic transducer suitable for a balanced armature electroacoustic transducer employing an electromagnetic drive method. The electroacoustic diaphragm includes a substantially flat plate-shaped diaphragm portion and a drive rod connection portion formed at an end portion of the diaphragm portion and connected to a drive rod. The diaphragm portion includes multiple dimples formed in such a manner that a base material forming the diaphragm portion is deformed in a thickness direction thereof such that one side of the base material is recessed and protrudes to the other side, and a flat portion formed among the multiple dimples such that the base material is not deformed in the thickness direction.

    摘要: A balanced armature (“BA”) based valve is described. The valve includes a motor having a coil assembly and a magnetic system, an armature extending through or being located adjacent to the motor, a drive pin coupled to the armature, and a valve flap of a membrane having a hole therein. The valve flap is actuated by the drive pin into open and closed positions, in response to respective motions of the armature. A housing contains the motor, the armature, the drive pin, and the membrane. In one embodiment, the membrane is attached to the housing and divides the housing into an upper space and a lower space, and there is airflow through the hole, between the upper space and the lower space, only when the valve flap is open. A first spout of the housing may deliver sound generated by an acoustic driver in the housing into a wearer's ear canal, and is also open to the upper space. A second spout of the housing is open to the bottom space and to an ambient environment. Other embodiments are also described.

    摘要: The present invention relates to a receiver assembly comprising a moving armature having a first portion and a second portion, and a first diaphragm being operatively connected to the first portion of the moving armature, wherein the first portion of the moving armature is operatively connected to the first diaphragm in a manner so that an angular momentum induced by movements of the first portion of the moving armature is essentially counteracted by an angular momentum induced by movements of the first diaphragm.
