    摘要： The present application relates to a backplate for a recording microphone, and the recording microphone, belonging to the technical field of acoustoelectric conversion. A surface, facing a diaphragm, of the backplate is a spherical surface recessed away from the diaphragm. According to the backplate for the recording microphone and the recording microphone provided by the present application, the maximum sound pressure level that the recording microphone can withstand is effectively increased, and the occurrence of attachment between the diaphragm and the backplate under the action of high-sound-pressure-level signals is reduced.

    摘要： A liquid-resistant acoustic assembly for an electronic device includes an acoustic device positioned in a housing, a gasket compressed between the acoustic device and the housing, and a liquid-resistant membrane. The liquid-resistant membrane is disposed such that it is isolated from a non-uniform compressive distribution resulting from compression of the gasket. The liquid-resistant membrane may be uncompressed by compression of the gasket or compressed by a different compressive force than the gasket. For example, the liquid-resistant membrane may not be positioned between the gasket and the acoustic device, may be separated from the gasket, may be mounted to a shelf of the gasket or within a gap defined by the gasket, mounted to a stiffener positioned within the gasket, and mounted using other similar configurations.

    摘要： A disclosed coaxial audio speaker may include a treble sound unit and a bass sound unit co-axially surrounding the treble sound unit. The bass sound unit may be in form of a single magnetic gap mechanism and have a vibrating vocal tone diaphragm along with a wiring board. The bass sound unit may further include a magnetic resistant ring selectively disposed therein. Within the magnetic resistant ring lies the treble sound unit. Therefore, the size of the audio speaker may be reduced because of the co-axially disposed bass sound unit and the treble sound unit. And the broader electricity adjustability may be achieved as vibration audio source points of the bass sound unit and the treble sound unit may be horizontally aligned.

    摘要翻译： 所公开的同轴音频扬声器可以包括高音单元和低音单元，它们同时围绕高音单元。 低音单元可以是单个磁隙机构的形式，并且具有与布线板一起的振动声乐振动膜。 低音单元还可以包括选择性地设置在其中的磁阻环。 在磁阻环内设有高音单元。 因此，由于同轴设置的低音单元和高音单元可以减小音频扬声器的尺寸。 并且由于低音单元和高音单元的振动音源源点可以水平对准，所以可以实现更广泛的电调节。

    摘要： A dynamic headphone unit includes a diaphragm to which a voice coil is fixed, a permanent magnet, a pole piece disposed adjacent one of the magnetic poles of the permanent magnet, and a yoke disposed adjacent the other magnetic pole of the permanent magnet. The pole piece and the yoke define a magnetic gap therebetween, and the voice coil is vibratably supported by the diaphragm in the magnetic gap. The voice coil includes a lead line for transmitting signal current. The lead line is bonded to the inner surface of a peripheral dome of the diaphragm with a pressure-sensitive adhesive.

    摘要： A diaphragm for a speaker is made by forming acrylic foam. As the material of the acrylic foam, using maleic anhydride and methacrylic amide are contained. Thereby, the coefficient of saturated water absorption can be reduced. When the diaphragm thus manufactured is used for a speaker device, the decrease of strength due to the water absorption and the deterioration of the sound quality can be prevented even in a humid environment.
