摘要： The utility model relates to an earphone with air release valve, comprising a shell, the shell is provided with an earphone rear cavity for accommodating a sounding unit, the sounding unit is placed in the earphone rear cavity and fixedly connected with the shell, the side of the shell facing the human ear is connected with an ear pad, the earphone is provided with an air release hole on the earphone shell between the earphone rear cavity and the earphone sound chamber cavity, and the air release hole is provided with an air release valve which automatically opens due to the increase of pressure. Therefore, when the people wear the earphone or transmit the earphone, the instantaneous pressure wave produced in the sound chamber cavity can be discharged from the air release valve. As for the earphone of the utility model, the vibrating diaphragm is less affected by the airflow interference such that the earphone is characterized by higher sound purity and better hearing experience compared with those earphones only having the air release hole rather than the valve.
摘要翻译：本实用新型涉及具有放气阀的耳机，包括壳体，壳体设有耳机后腔，用于容纳探测单元，探测单元放置在耳机后腔中，与外壳固定连接面向人耳的外壳与耳垫连接，耳机在耳机后腔和耳机音腔之间的耳机壳上设置有空气释放孔，并且空气释放孔设有空气释放阀由于压力的增加而自动打开。因此，当人们佩戴耳机或者传送耳机时，可以从空气释放阀中排出声室腔中产生的瞬时压力波。对于本实用新型的耳机，振动膜较少受到气流干扰的影响，与仅具有空气释放孔而不是阀的耳机相比，耳机的特征在于具有更高的声音纯度和更好的听觉效果。

摘要： A personal audio system enabling a user to distinguish approximate locations of sound sources comprises at least one sound receiver. The sound receiver comprises a sound collecting structure for collecting sound. The sound collecting structure comprises a plurality of sound passages opening toward different directions and with different sizes to collect sound waves from the environment. The different sizes of the openings render a decline or an increase in specific frequency ranges of sound as a result of different resonances via the different openings. The user may therefore distinguish the direction of a sound source based on the slightly different pitches (frequencies) of the sound.

摘要： A headphone includes an ear-cup housing and an audio driver. The audio driver has a driver housing, and a driver aperture extending through the audio driver from an exterior thereof toward a diaphragm. A mass port plug is disposed at least partially within the driver aperture extending through the audio driver. The mass port plug has an acoustic aperture extending through the mass port plug from a first side thereof to an opposing second side thereof, and the acoustic aperture is configured to cause the audio driver to exhibit a selected detectable sound pressure level (SPL) profile. Methods of fabricating headphones include insertion of such a mass port plug into a driver aperture extending through an audio driver. The mass port plugs and methods may be used to adapt substantially identical audio drivers for use in ear-cup housings having differing configurations while providing selected detectable sound pressure level profiles.

摘要： A loudspeaker and a method of operation which allow for the production and emphasis of extremely low bass tones. The loudspeaker generally is formed from a loudspeaker driver cone of conventional type which is placed in a very small enclosure with two waveguides attached thereto. A smaller balance waveguide is positioned forward of the face of the cone and a larger tuning waveguide is positioned to the side of the cone. The cross-sectional area of the aperture connections of both waveguides to the enclosure are small compared to the cross-sectional area of the loudspeaker driver cone.
