A magnetically attractable Bluetooth speaker is disclosed, including a speaker housing, a loudspeaker, a control circuit board, and a magnet. The loudspeaker is electrically connected to the control circuit board. The speaker housing includes a limiting part for securing the magnet. The magnet is fixedly arranged in the limiting part, and the magnet is arranged outside the magnetic circuit range of the loudspeaker. With such a structure, by arranging the magnet in the speaker housing, the user experience of the speaker can be greatly improved, so that the user can place it in different manners depending on their different needs. Compared with the traditional ordinary speakers that can only be placed on a horizontal plane or a surface with a small slope, the speaker provided by the present disclosure has better flexibility in use.

An isolating system and method for dampening vibrations between vibration-generating or vibration-sensitive equipment and a support structure. The isolating system includes first and second housing sections connected to one another via a vibration dampening assembly. The first housing section is secured to the support structure and includes a frame and first isolator assembly. The second housing section includes a second isolator assembly positioned between the frame and first isolator assembly. The vibration dampening assembly connects the first and second isolating assemblies to one another and prevents direct physical contact between them. One of a flange assembly and flange assembly of an attachment assembly is engaged with a connector region of the second isolator assembly and is used to secure the equipment to the second isolator assembly. The vibration dampening assembly reduces transmission of vibration between first and second isolator assemblies and thereby between the equipment and support structure.

The present disclosure relates to an acoustic output apparatus. The acoustic output apparatus comprising: at least one low-frequency acoustic driver that outputs sound from at least two first sound guiding holes; at least one high-frequency acoustic driver that outputs sound from at least two second sound guiding holes; and a controller configured to cause the low-frequency acoustic driver to output sound in a first frequency range, and cause the high-frequency acoustic driver to output sound in a second frequency range, wherein the second frequency range includes frequencies higher than the first frequency range.

Systems and methods are disclosed herein for an audio speaker bracket for use water based and land-based vehicles and a method for installing the speaker to a mounting panel using at least one suspension member. The method permits the speaker to be supported by a secure attachment of the bracket to the vehicle is proposed.

A vibration dampening device, a mounting assembly including a vibration dampening device, and a method of dampening vibration in a vibration-sensitive component using the same. The vibration dampening device includes a first member that rests upon or is operatively engaged with a support surface; a second member that is operatively engaged with the vibration-sensitive component; and at least one isolator assembly interposed between the first member and the second member, wherein the first member and the second member are decoupled from one another by the at least one isolator assembly. The at least one isolator assembly includes a first isolator that is at least partially embedded in the first member and a second isolator that is at least partially embedded in the second member, and an isolator insert that extends between the first isolator and second isolator. The isolator insert creates a gap between the first and second members.

The present invention relates to a chair including a multi-channel sound system, and more particularly, to a chair including a multi-channel sound system capable of providing rich sound effects to a user who sits in the chair through sounds output from a plurality of channels.

A voice augmentation device disposed at a specific position with respect to a droplet suppressing member disposed between a speaker and a listener to suppress droplet generated from at least one of a mouth and nose of the speaker causes a base vibration input part to receive vibration from at least one of the droplet suppressing member and air between the droplet suppressing member and the base vibration input part, causes a mounting part to receive the vibration from the droplet suppressing member, causes a coupling part to receive the vibration from at least one of the droplet suppressing member and air between the droplet suppressing member and the coupling part, and causes a base vibration output part to transmit the vibration received by the base vibration input part, the mounting part, and the coupling part to air on a side of the listener.

A guitar holder with a built-in guitar amplifier for enabling convenient guitar practice and/or play with a compact, space-saving footprint. The guitar holder may comprise any of a variety of guitar holders, including but not limited to a guitar stand and/or a guitar wall hanger.

A support and retainer system for a wired headphone is herein disclosed. The system includes a stand and a holding device. The stand includes a base, a cradle for supporting a mobile device, with the cradle coupled to the base, and a pair of arms extending from the cradle, with each arm configured to retain a respective headphone wire. The holding device is designed to windably maintain the wired headphone such that the wired headphone can be extended and retracted effectively, quickly, and without becoming tangled, in use.

An audio system includes an audio/video receiver, a power supply/wireless audio distribution assembly connected to the audio/video receiver, speaker wire, and speakers compatible with the power supply/wireless audio distribution assembly.
