The present disclosure relates to a method and system for calibrating a loudspeaker system in an environment (1). The loudspeaker system comprises an audio device (10) with a first and second loudspeaker arranged with a predetermined horizontal separation. The method comprises the steps of emitting (S2a, S2b) a first and second calibration audio signal from the first and second loudspeaker (11) of the audio device (10), wherein the second calibration audio signal is distinguishable from the first calibration audio signal. The method further comprises receiving (S3a, S3b), with a first external microphone (20) the first and second calibration audio signal, determining (S4) the position of the first external microphone (20) relative to the audio device (10) and calibrating (S8) the loudspeaker system based on the determined position of the first external microphone (20).

An assembly including a speaker and a stand. The speaker including a speaker housing, speaker components supported in the speaker housing and operable to produce and audio output, and a rechargeable power source operable to power the speaker components. The stand being operable to support the speaker, the stand including a stand housing and a stand electrical circuit connectable to an external power source. The speaker and the stand are operable to perform a charging operation, the charging operation including the speaker supported on the stand and power supplied to the rechargeable power source. During the charging operation, the speaker components are operable to produce the audio output.

Provided is a loudspeaker device that can improve sound quality. The loudspeaker device includes: a loudspeaker housing; a first loudspeaker unit provided in a first wall of the loudspeaker housing; and an acoustic tube communicating an inside and an outside of the loudspeaker housing to each other. The acoustic tube has a predetermined length, and is accommodated in the loudspeaker housing and is helically shaped.

The present disclosure relates to a loudspeaker. The loudspeaker may include a loudspeaker mechanism, a fixing mechanism, and a connector. The loudspeaker mechanism may be configured to generate a vibration signal and transmit the vibration signal to the human body. The fixing mechanism may be configured to support and maintain the position of the loudspeaker mechanism. The connector may be configured to connect the loudspeaker mechanism with the fixing mechanism. The loudspeaker mechanism may at least include a first fixed position and a second fixed position. The first fixed position may be a fixed position of the loudspeaker when the loudspeaker is in a non-working state. The second fixed position may be a fixed position of the loudspeaker when the loudspeaker is in a working state. The connector may be configured to switch the loudspeaker mechanism between the first fixed position and the second fixed position.

The present invention provides for a woven mesh element for an electroacoustic driver enclosure, and to an electroacoustic driver enclosure including such an element, wherein the element comprises a plurality of mesh layers, and wherein the said plurality of layers includes a layer of Dutch weave mesh preferably comprising a layer of Dutch Twill weave mesh, and in particular wherein the element comprises plural layers of cross woven wire mesh and a layer of Dutch weave wire mesh.

Electronic equipment may include seamless spacer fabric. Seamless spacer fabric may be used as a protective case or cosmetic cover for an electronic device such as a speaker. A seamless spacer fabric may include a seamless fabric outer layer, a spacer fabric inner layer, and an adhesive layer that bonds the seamless outer layer to the spacer fabric inner layer. The spacer fabric layer may have a seam region where one portion of the spacer fabric layer is joined with another portion of the fabric layer. The seamless fabric outer layer may cover the seam region to hide it from view. One or more additional seam hiding layers or strips may be formed on opposing sides of the spacer fabric layer to cover the seam. The seamless spacer fabric may have an array of openings that extends uniformly around the perimeter of the seamless spacer fabric.

A speaker cabinet to effectively amplify an acoustic guitar, comprising of: two chambers, two speaker drivers, a port, and a tube within the port. One speaker driver is mounted onto front of tube to radiate sound outwards, while the rear sound waves radiate through same tube into ported resonant chamber. The second chamber is sealed, is next to ported chamber, and utilizes a second speaker driver. The front sound waves of second driver radiant into ported resonant chamber, while the rear waves radiate into the sealed chamber. The two distinct sound waves now inside ported chamber mix with each other, then flow around the tube and through the port. All three sound waves mix in front of the cabinet. Other embodiments include: Sound deflectors, horn-loading the port, a passive radiator on the sealed chamber to radiate a fourth sound wave, and a guitar shape inside the ported resonant chamber.

The present disclosure embodiment may disclose a glasses. The glasses may include a glasses frame and two speakers. The glasses frame may include a glasses rim and two glasses temples. The two glasses temples may be rotatably connected to the glasses rim, respectively. The two speakers may be connected to the two glasses temples via hinge components of the two glasses temples, respectively. The hinge components may be rotatable to change a position of each of the speakers relative to one of the glasses temples. The two speakers may include an earphone core and an earphone housing. The earphone housing may include a housing panel facing a human body and a housing back opposite to the housing panel. At least one of the glasses temples may include a control circuit or a battery. The control circuit or the battery may drive the earphone core to vibrate to generate sound. A vibration of the earphone core may result in vibrations of the housing panel and the housing back. The vibration of the housing panel may have a first phase, and the vibration of the housing back may have a second phase, vibration frequencies of the housing panel and the housing back may be in a range of 2000 Hz to 3000 Hz, and an absolute value of a difference between the first phase and the second phase may be less than 60 degrees. In the present disclosure, a function member may be connected to the glasses through the hinge component to expand use of the glasses.

An internet protocol (IP)-based ceiling or wall-mounted speaker with optional IP-based camera and/or alarm indicator is provided. The IP-based speaker has a detachable add-on device for accommodating different types of interchangeable camera configurations and other components such as flush mount camera, camera providing angled view, night vision-type camera for different services and configurations.
