    • A cushion for a headset earphone comprises a resilient ring having opposite input and output faces, and a through-opening defining an interior surface between the two faces. The input face has structure for acoustically coupling the opening to an output face of an audio speaker, and the output face is resiliently conformable to a lateral face of an external ear of a listener, thereby acoustically coupling the opening, and hence, the speaker, to the listener's ear. The interior surface of the cushion can be configured to effectively match the acoustical impedance at the output face of the speaker to the acoustical impedance at the entrance of the listener's ear. In one possible embodiment, the ring is formed of an elastomer filled with microcapsules containing a material capable of an endothermic phase changes at a constant temperature, such that the cushion more effectively conducts heat away from the ear, thereby providing long term listening comfort. In another embodiment, the through-opening is acoustically coupled to the output of the transducer with an acoustic plug such that the cushion is flexibly articulated about the plug relative to the speaker, thereby enabling the cushion to comply more easily to the listener's ear using lower contact forces between the cushion and the ear.
    • 用于耳机耳机的垫子包括具有相对的输入和输出面的弹性环和限定两个面之间的内表面的通孔。 输入面具有用于将开口声耦合到音频扬声器的输出面的结构,并且输出面弹性地适配于收听者的外耳的侧面,从而将开口(因此,扬声器) 听众的耳朵。 衬垫的内表面可以被配置成将扬声器的输出面处的声阻抗与听者耳朵的入口处的声阻抗有效地匹配。 在一个可能的实施例中,环由填充有包含能够在恒定温度下具有吸热相变的材料的微胶囊填充的弹性体形成,使得该衬垫更有效地将热量从耳朵传导,从而提供长期的收听舒适度。 在另一个实施例中,通孔通过声学插塞声耦合到换能器的输出端,使得缓冲垫相对于扬声器围绕插头灵活地铰接,从而使得缓冲垫能够更容易地符合收听者的耳朵,使用较低的 垫子和耳朵之间的接触力。
