    • An earpiece, an electronic device, and a communication device, capable of reducing the influence of leakage of sounds from a clearance between the earpiece and an ear not to need an addition of parts are provided. An earpiece (100) includes an electromechanical acoustic transducer (10) having a diaphragm and for generating a sound by vibrating the diaphragm in response to an electric signal, a case (11) on which a sound hole (12) is provided and in which the electromechanical acoustic transducer (10) is housed, and a holding member (13) for holding the electromechanical acoustic transducer (10) in the case (11). The electromechanical acoustic transducer (10) has a sound pressure-frequency characteristic that is compensated in advance such that the sound pressure-frequency characteristic is planarized in a condition that the generated sound is leaked from a user's ear (14) being covered with the case (11).
    • 提供了一种耳机,电子设备和通信设备,其能够减少来自耳机和耳朵之间的间隙的声音泄漏的影响,而不需要添加零件。 听筒(100)包括具有隔膜的机电声学换能器(10),用于响应于电信号振动隔膜产生声音;壳体(11)上设有声孔(12),其中 容纳机电声换能器(10),以及用于将机电换能器(10)保持在壳体(11)中的保持构件(13)。 机电声换能器(10)具有预先补偿的声压频率特性,使得在产生的声音从用户的耳朵(14)泄漏的情况下,声压频率特性被平坦化 (11)。
