    摘要: The present invention relates to a vehicle door, which is installed on the vehicle. The door includes a shutter, a speaker and an inverted tube. The shutter has an accommodation cavity, and the speaker is installed in the shutter. The inverted tube is located in the accommodation cavity, with one end connected with the interior of the vehicle, and the other end forming an acoustic port with a flange. The inverted tube exports the sound from the rear cavity into the car. The inverted tube with the acoustic port can strengthen the resonance effect of the air, and strengthen the sound wave. It can improve the loudness of the speaker, reduce the noise of the airflow, and effectively improve the sound quality of the speaker.

    摘要: A narrow-profile balanced subwoofer or similar speaker includes a number of drivers placed side by side in the same lateral plane, with a first set of drivers facing one direction and second set of drivers facing the opposite direction. Their orientation is such that the sum of the forces from the first set of drivers is equal and opposite the sum of the forces from the second set of drivers, thus cancelling, and the sum of the moments from all of the drivers about a center or pivot point substantially equals zero. The speaker may include three or more drivers, symmetrically or asymmetrically spaced. The drivers may be of the same or different sizes, and the audio signal amplitudes may be adjusted to help balance the speaker. Each set of drivers may output sound into separate sound ducts, which may output sound from one or more apertures.

    摘要: An acoustic resistor for use in an audio device includes a resin film having air permeability in a thickness direction of the resin film, and the resin film is a non-porous film having through holes formed to extend straight through the resin film in the thickness direction. This acoustic resistor is used in an audio device including: a transducing part that performs conversion between sound and an electrical signal and that includes an acoustic element; a housing enclosing the transducing part and having at least one opening; and a passage for gas that is present inside the housing and communicates with the opening and in which the acoustic element is placed. The acoustic resistor is placed between the opening and the acoustic element in the passage. The variation in properties of the acoustic resistor of the present disclosure can be made smaller than that of conventional acoustic resistors.

    摘要: A condenser microphone includes a unit case that supports a condenser microphone unit, has an internal space in communication with a rear acoustic terminal of the microphone unit, and has an opening in a peripheral wall in communication with the internal space; a volume restrictor that reduces the volume of the internal space by partitioning the internal space; a circuit board disposed in the internal space and surrounded by the volume restrictor; and a rigid conductor that electrically connects a signal output terminal of the microphone unit and the circuit board. The circuit board intersects the center axis of the unit case. The rigid conductor is supported such that the rigid conductor slides along the volume restrictor. An elastic conductor is compressed between the rigid conductor and the circuit board or between the rigid conductor and the signal output terminal of the microphone unit.

    摘要: Clock synchronization for an acoustic echo canceller (AEC) with a speaker and a microphone connected over a digital link may be provided. A clock difference may be estimated by analyzing the speaker signal and the microphone signal in the digital domain. The clock synchronization may be combined in both hardware and software. This synchronization may be performed in two stages, first with coarse synchronization in hardware, then fine synchronization in software with, for example, a re-sampler.
