    摘要： A sound output device according to an embodiment of the present disclosure includes a speaker configured to generate sound; a guide tube formed in a shape of a hollow tube, the guide tube configured to receive the sound generated from the speaker, through an end of the guide tube, and output the received sound; and a waveguide disposed between the speaker and the guide tube. The waveguide includes a throat tube configured to connect the speaker and the guide tube to each other, and formed in a shape of a hollow tube, and at least one path change structure configured to adjust a predetermined frequency band of the sound in a process of transmitting the sound generated from the speaker to the guide tube.

    摘要： A compact audio woofer arrangement for a motor vehicle includes an enclosure installed in the motor vehicle. The enclosure contains a woofer or subwoofer emitting a sound. The enclosure includes a primary and secondary through-hole. The primary through-hole allows the woofer to interface with the interior of the vehicle and provides sound directly from the enclosure into a passenger compartment at the primary location. A extended vent acting as an acoustic transmission line is coupled to the second through-hole. The vent transmits sound from the enclosure to a secondary location remote from the primary location, such that the sound is emitted into the adjacent passenger compartment. The primary and secondary acoustic outputs differ by physical location in the motor vehicle, and also by frequency response of the emitted sound, thereby emulating a quasi-stereo environment.

    摘要： An audio device includes a plurality of reflective components that reflect sound emitted from a loudspeaker unit. The audio device forms a reflective space surrounded by the plurality of reflective components. The audio device includes an acoustic channel that is tube-shaped and includes an opening on one end and a terminating portion on an other end, the one end being connected to a communication hole provided in a reflective component among the plurality of reflective components, and a sound absorbing material disposed at a central portion of a sound path formed by the acoustic channel.

    摘要： An Acoustic meta material (AMM) device for passive amplification of sound is described. The AMM amplifier device employs a deep sub-wavelength resonator design with high refraction index, which uses resonant amplification of the bass sound. An array of sub wavelength, single frequency channels are used, each resonating and amplifying at a different frequency in the bass frequency range. This is accomplished by having many different channels, each with an opening extending in a same, common, or substantially common direction. Thus, sound emanating from a speaker in a first direction continues in this direction until reaching and entering the openings of the plurality of channels. The sound from the speaker is in all transmitted frequencies of, for example, a musical recording or the like. However, only a specific frequency and/or harmonics thereof are substantially propagated through each channel.

    摘要： Presented herein is an audio endpoint for telecommunication operations, sometimes referred to herein as a “telecommunications audio endpoint” or, more, simply as an “audio endpoint.” According to at least one example, the audio endpoint presented herein includes a base, a speaker, a speaker waveguide, a microphone waveguide, and two or more microphones. The base is configured to engage a support surface (i.e., a table) and the speaker is configured to emit sounds (i.e., fire) in a direction of the base. The speaker waveguide is disposed between the speaker and the microphone waveguide, while the microphone waveguide is disposed between the speaker waveguide and the base. The two or more microphones are disposed within the microphone waveguide and are proximate to the base. In general, the speaker waveguide is configured to guide sounds output by the speaker in general radially (outward) directions.
