According to certain aspects, the present invention aims at presenting a more natural, spatially accurate sound, for example to a user at the desired location who is wearing a helmet, mimicking the sound a user would experience if they were not wearing any headgear. Modes for enhanced spatial hearing may be applied which would include situation-dependent processing for augmented hearing. According to other aspects, the present invention aims at remotely reproducing the soundfield at a desired location with faithful reproduction of the spatial content of the soundfield.

  • Patent number: 9516403
    Abstract: An earphone with stand-alone high-frequency driver includes a casing, a low-frequency driver, a high-frequency driver, and a protecting cover. The casing defines a sound-guiding passage and a separating wall. The separating wall is formed on a side surface of the sound-guiding passage and defines a sound port, which is in communication with the sound-guiding passage. The high-frequency driver is disposed next to the separating wall and defines a sound-outputting direction. The protecting cover is mated to the casing and covers the high-frequency driver. The sound waves generated by both low- and high-frequency drivers are delivered externally through the sound-guiding passage. The earphone allows structural modifications and assembling the high-frequency driver and the protecting cover after a half-finished product (casing and low-frequency driver) is obtained.

  • Patent number: 9479855
    Abstract: A headphone ear cup includes a composite cushion and a cover wrapping around the composite cushion. The composite cushion has an annular body and an air-permeable portion arranged at the outer periphery of the annular body. The air-permeable portion is made of a porous material having a porosity higher than that of the annular body. Because the annular body made of the material having relatively high density can maintain the sound output performance of the earphones, and the air-permeable portion made of the porous material having relatively low density can provide better heat dissipation effect, the headphone ear cup has excellent air-permeable property and improved acoustic field effect.

  • Patent number: 9473844
    Abstract: [Problem] To prevent sound leakage through gaps between the wearing surface side of ear pads and areas around the ears when headphones are worn and used by a user. [Solution] For headphones that have ear pads which are attached to the surfaces of housing sections, each having a built-in speaker driver for outputting an audio signal as sound, which come in contact with the ears of a listener, convex sections in the form of gradually curved surfaces are provided in the wearing surface regions of the ear pads that come in contact with an upper anterior side of the head of the listener and a lower posterior side of the head of the listener, whereby the ear pads are shaped to fit well to the areas around the ears of the user without forming any gaps when the ear pads are worn.

  • Patent number: 9438980
    Abstract: A headphone ear cup for mounting on a surface of a speaker unit of a headphone includes an annular cushion having a sound hole at a center thereof, and a composite cover having a ventilative layer and an air-tight layer. The composite cover wraps around the annular cushion and defines an inner-side portion, an outer-side portion and an ear-abutting portion. The ventilative and air-tight layers are respectively formed by the outer-side portion and a composite of the inner-side and ear-abutting portions or by a composite of the outer-side and ear-abutting portions and the inner-side portion. Therefore, the ventilative layer and the annular cushion form a good heat dissipation path to have excellent air-permeable property, and air-tight layer provides an improved acoustic field effect.

  • Patent number: 9414154
    Abstract: A water-repellent earphone is formed of a main body and a water-repellent breathable member. The main body includes a receiving space for accommodating a speaker. The speaker partitions the receiving space to make a rear chamber. The main body includes a drainage tunnel communication with a first opening and a second opening, both of which are located on an external surface of the main body. The main body further includes a venthole communicating with the drainage tunnel and the rear chamber. The water-repellent breathable member is formed and located at the venthole. In light of the structure mentioned above, the drainage tunnel can help the earphone quickly expel the moisture to prevent the moisture from damage to the speaker and to boost the frequency response and acoustic performance within the low-frequency range.
