Embodiments of the inventive subject matter described in this application are directed to headset audio systems that incorporate components designed to improve sound reproduction in certain ranges. For example, in some embodiments, an acoustic chamber and a venting portion are incorporated into an internal portion of a headset audio system such that the vent is configured to improve bass response. Different vent shapes and sizes can affect speaker performance. Moreover, in some embodiments, the acoustic chamber can additionally include a vent.

Provided is a device 1 including: a signal processing unit 40 that applies a rotary speaker effect corresponding to a rotation speed value to a sound signal and control a tone color of the sound signal; and a control unit 10 that gradually changes, in response to a change command of the rotation speed value, the rotation speed value from a first speed to a second speed higher than the first speed with a first change curve having a first delay, and gradually changes control of the tone color from a first characteristic to a second characteristic that is stronger in the high frequency range than the first characteristic with a second change curve having a second delay shorter than the first delay.

According to an aspect of the disclosure, a loudspeaker includes an enclosure. The enclosure includes a first plurality of sidewalls. The loudspeaker further includes a horn. The horn is defined in part by the first plurality of sidewalls. The horn includes a second plurality of sidewalls that are coupled to the first plurality of sidewalls and that include a first sidewall and a second sidewall. The horn further includes a motorboard that includes a first opening arranged along a plane and a second opening arranged along the plane. The motorboard is coupled to the first sidewall and the second sidewall. The loudspeaker further includes an active driver arranged concentric to the first opening to transmit sound waves directly through the first opening, and a passive component arranged concentric to the second opening to transmit sound waves directly through the second opening.

A speaker includes: a diaphragm having a dome shape; a tubular member having the diaphragm disposed inside, and having an inner diameter increasing toward a front; and a phase plug. The phase plug includes: a front surface, a rear surface facing a central portion on a front surface of the diaphragm at a constant interval in parallel, and a side surface connecting the front surface and the rear surface. A front surface of the phase plug is larger than a rear surface of the phase plug as viewed in a front-rear direction of a speaker. At least a part of a side surface of the phase plug has an inclined surface extending outward while extending forward, faces an inner circumferential surface of the tubular member and a front surface of the diaphragm, and directs a sound wave generated from the diaphragm toward an inner circumferential surface of the tubular member.

The present application discloses a speaker, including a shell and a speaker unit. The speaker unit includes a frame, and a magnetic path assembly and a vibration assembly; wherein, a guide pipe is also arranged in the receiving space. Compared with the related art, the present invention has the advantages that the guide pipe having a first through hole is provided; a magnetic bowl is provided with a second through hole in a penetrating manner; a main magnet is provided with a third through hole in a penetrating manner; a support is provided with a fourth through hole in a penetrating manner; all the above through holes are communicated in sequence. Thus, air of a region of the rear cavity can be introduced to the front cavity, which achieves effects of increasing the loudness of the speaker and optimizing the acoustic performance.

A compression driver for an omnidirectional loudspeaker includes a motor assembly and a dome diaphragm disposed coaxially above and operably connected to the motor assembly, the diaphragm having a convex surface and a concave surface. The compression driver includes a phasing plug having a top portion and a bottom portion having a concave bottom surface disposed adjacent the convex surface of the diaphragm and defining a compression chamber therebetween. The phasing plug includes a plurality of conduits extending through the bottom portion for sound waves to travel and converging to form an annular exit, the top portion including a plurality of radially expanding channels acoustically connected to the annular exit. Actuation of the diaphragm by the motor assembly generates sound waves within the compression chamber which travel through the annular exit and the radially-expanding channels to create a generally horizontal 360° radiation pattern of the sound waves from the compression driver.
