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.

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.

Abstract: The present invention discloses an interactive biosensing device and a method thereof. The interactive biosensing device is arranged on a living body and comprises a physiological detection module detecting physiological signals of the living body; a physical sensation module triggering at least one physical device according to control instructions; a first wireless transmission module receiving control instructions or sends out physiological signals; a storage module storing physiological signals and control instructions; a video module capturing images of the living body; a control module processing physiological signals and control instructions and controlling operations of the video module; and a display unit presenting the images captured by the video module.

Abstract: The present invention discloses an automatic bio-signal supervising system for medical care. The automatic bio-signal supervising system utilizes a head-mounted bio-signal acquisition device, wore upon the user's head, to acquire the bio-signals, convert them into the digital bio-signals, and transmit the digital bio-signals to a signal analysis processor to perform analysis process. And the automatic bio-signal supervising system delivers a corresponding control signal to the environment control equipment based on the result of analysis, and control the environment condition to achieve the remote supervising and medical care purpose. Furthermore, the signal analysis processor in the present invention further provides a real-time warning signal or a health index, which supervise the personal biological information to avoid the unpredictable situation.
