Abstract: [Problem] To provide a headphone device that outputs an audio signal output from a playback device, such that the headphone device has a more compact housing while being capable of highly sensitive acoustic output of an audio signal having high sound quality, and is capable of consuming less power during highly sensitive acoustic output of an audio signal having high sound quality. [Solution] In a headphone device that outputs an input audio signal, the headphone device is provided with: a housing shaped with a hollow interior, said housing being provided with a projection on the front thereof, said projection being provided with a hole passing therethrough in the front-to-back direction; and a first driver unit and second driver unit each affixed to the inner wall of the housing, and each having a diaphragm that acoustically outputs the input audio signal. The first driver unit and the second driver unit have been given a parallel arrangement, such that the diaphragms thereof are in mutual opposition.

Abstract: [Problem] To provide a headphone device that is equipped with an ear pad to be inserted into an ear, is electrically connected to a player device via a cable and outputs an audio signal which is output from the player device, with which it is possible to improve in-ear wearability and prevent a pain from being caused inside the ear. [Solution] The headphone device is equipped with: a driver unit that is fixed to a housing and has a diaphragm for emitting a sound of an audio signal; and a nozzle section that is fixed to the housing at one end, holds an ear pad at the other end, has a hollow interior, and is formed so as to slope from the part where the nozzle is fixed to the housing toward the tip of the nozzle section at a predetermined angle with respect to the housing.

Abstract: [Problem] In a system that transmits content data from a content replay device to a content output device, to prevent a deterioration in audio quality or video data picture quality while being able to increase the simplicity of a setting-altering operation without requiring complicated signal processing.

Abstract: [Problem] The purpose of the present invention is to provide a neckband-type earphone that can be worn for a long time without subjecting the wearer to discomfort of wearing a neckband-type earphone, and in which the extent of hazard to the wearer when worn is lowered and locations that break are reduced. [Solution] A neckband-type earphone provided with: earphone parts which are inserted into the pinnae of the wearer and which output an audio signal; ear holder parts which connect to the earphone parts and which abut the upper side of the pinnae of the wearer; holder bodies provided with the ear holder parts; earphone drivers provided with the holder bodies; and a neck band connecting the two earphone drivers; the holder bodies being provided with a cushion part at a portion that comes into contact with the head of the wearer in the vicinity of the pinnae.

Abstract: [Problem] In a system for transmitting content data from a content reproducing apparatus to a content output apparatus, no complicated signal processing is required, setting change operations can be simplified, and the degradation of sound quality and the degradation of picture quality of video data are prevented.

Abstract: A device, method, and system for managing authorization for rendering of digital media recordings by a networked rendering device are disclosed. The device includes a processor and a memory. The device receives metadata identifying a recording of a specific audio performance, and searches for a source providing the recording. The device obtains a token authorizing the source to deliver the recording to the rendering device. The device provides the token to the source, receives the recording from the source, and renders the recording. An agent may serve as an intermediary between the rendering device and the source.

Abstract: [Problem] To provide a network AV receiver device capable of preventing the suspension of the playback of music when the music can no longer be inputted from a media server that is inputting the music, the network AV receiver device playing back the music inputted from the media server, which is connected via a network and accumulates music.

Abstract: A reproduction device, contains a rotatable operation disk part for performing an input related to reading of data stored in a memory and a capacitance sensor section for outputting a sensor value expressing a change of a capacitance according to depression of the rotatable operation disk part. The device also contains a storage part for storing a reference value corresponding to the sensor value obtained while the rotatable operation disk part is not depressed, and a control part for judging presence/absence of pressing on the rotatable operation disk part based on a vector quantity being a relative value obtained from a difference between the sensor value output from the capacitance sensor section and the reference value stored in the storage part.

Abstract: An audio signal interpolation device is presented, including an input unit for receiving an input audio signal, a phase splitting unit for splitting the input audio signal, a high range interpolation unit for interpolating a high range component into the signal, a phase combining unit for combining an in-phase component signal with a differential phase component, a high-pass filter for high-pass filtering the audio signal from by the phase combining unit, a delay unit for producing a delayed audio signal, and an addition processing unit for adding the delayed audio signal to the audio signal output from the high-pass filter.
