Abstract: Method and devices for testing a headphone with increased sensation are provided. The headphone can filter and amplify low frequency audio signals, which are then sent to a haptic device in the headphone. The haptic device can cause bass sensations at the top of the skull and at both ear cups. The testing system can evaluate the haptic and acoustic sensations produced by the headphone to evaluate if they have been properly assembled and calibrate the headphones if necessary.

Abstract: Audio (noise source) is output as a cancellation sound through a variable filter and a first filter, and transmitted to the second filter. A subtractor subtracts an output of a second filter from an output of a microphone, and an adaptive algorithm execution unit updates a transfer function of the variable filter so that the subtracted result becomes zero (0). A transfer function A for the first filter is a transfer function which can cancel noise at a position of a user's ear by setting, as the cancellation sound, a sound obtained by applying the transfer function A to audio at the time of learning, and a transfer function B for the second filter is a transfer function which can eliminate, for the cancellation sound, a difference between a sound obtained by applying the transfer function B to audio and the output of the microphone.

Abstract: An electrical connector casing enclosing an electrical connector comprises a case part having a connector inlet, and a lid part having a lid opening, where the openings of the connector inlet and the lid opening have a substantially the same shape and are angled differently from each other as viewed from a front-back direction. An electric connector is inserted from the back of the lid part through the lid opening, and is rotated to be inserted into the connector inlet from the back of the case part. When the lid part attaches to the case part, due to the rotationally different angles between the lid opening and the connector inlet, the electric connector is securely held inside the casing.

Abstract: A digital amplifier integrated circuit (“IC”), which is a heat-generating electronic component, is mounted on an upper surface of an insulating substrate. The digital amplifier IC is disposed inside a recess of a heat sink. The heat sink includes a peripheral wall having an end face placed on the upper surface of the insulating substrate. A hot-melt resin layer, molded by hot-melt molding, covers the upper surface of the insulating substrate. The hot-melt resin layer is in contact with a side face of the peripheral wall and retains the heat sink on the insulating substrate. The recess of the heat sink has no hot-melt resin therein.

Abstract: An electronic unit includes an electrolytic capacitor, a covering resin layer, and electronic components. The electrolytic capacitor is on an upper surface of an insulating substrate. The covering resin layer covers the upper surface of the insulating substrate and the electronic components. Part of the covering resin layer serves as an electrolytic capacitor covering portion. The electrolytic capacitor covering portion includes an outer peripheral covering portion that covers an outer peripheral surface of the electrolytic capacitor and a top covering portion that covers a top portion of the electrolytic capacitor. A thin wall groove is formed in the top covering portion. The outer peripheral covering portion extends upward beyond the top covering portion by a height h. The top covering portion easily breaks at the thin wall groove so that an explosion-proof valve easily operates. A region corresponding to the height h creates an operating space of the explosion-proof valve.

Abstract: In an electroacoustic converter, a dome-shaped diaphragm having anisotropy in rigidity is formed by shaping fiber reinforced plastic having anisotropy in fiber orientation. A voice coil bobbin, in a hollow cylindrical shape, on which a voice coil is wound is linked to the outer edge of the diaphragm so that the shape of the linked portion becomes circular when viewed in the axial direction of the diaphragm. The diaphragm vibrates due to an electromagnetic action by a magnetic flux that is generated in a magnetic circuit and flows in the voice coil and the current of an audio signal flowing in the voice coil.

Abstract: An opening portion is formed along an outer peripheral edge of a diaphragm in a second casing portion partitioned by the diaphragm. In the opening portion, a plurality of fins is arranged at regular intervals, and an air passage is formed between every adjacent two of the fins. The fin and the air passage are formed so as to be at an angle to a corresponding imaginary line that extends from the vibration center line of the diaphragm in the radial direction. By forming each of the air passages obliquely, noise generated by an air flow due to sound pressure is reduced.
