Abstract: A link includes an arm having first and second recess/apertures, receiving first and second bearings, respectively. The bearings are attachable to structures, allowing movement of one structure independently of the other. The recess/aperture has an inward facing surface, and the bearing has an outward facing surface, the inward and outward facing surfaces being substantially arcuate. An isolator includes a base and shell connected to but extending from the base. The shell has an aperture opposite the base. A support structure has one end in the shell. The connecting arm has a component thereon outside the shell whereby the connecting arm connects to a structure. Links are pivotally connected at one end to the shell and pivotally connected at the other end to the connecting arm. The connection between each link and the connecting arm is closer to the base than the connection between each link and the shell.

Abstract: A speaker box and an electronic device are disclosed. The speaker box includes an upper cover plate including side walls, a first lower cover plate, a speaker unit, a motor module, and second lower cover plates. The speaker unit divides an accommodating cavity defined by upper cover plate and first lower cover plate into front and back cavities. The second lower cover plates are assembled with the upper cover plate to define compensation cavities. A length of at least one of the side walls of the upper cover plate is greater than that of an orthographic projection thereof, so the speaker box is suitable for various electronic devices and has strong adaptability and wide application. The compensation cavities are communicated with the back cavity, which increases an overall space of the back cavity, improves low-frequency performance of the speaker unit, and improves sound production effect of the speaker unit.

Abstract: The present disclosure discloses a speaker box including a shell and a speaker unit accommodated in the shell. The shell is provided with an acoustic channel for emitting sounds generated by the speaker unit from a side of the speaker box. A supporting wall for supporting and fixing the speaker unit is formed in the shell. The supporting wall is provided with a gap at the acoustic channel. A reinforcing rib is formed in the acoustic channel. A supporting rib extends from an end of the reinforcing rib close to the speaker unit into the gap. The speaker unit is supported and fixed on the supporting wall and the supporting rib. The speaker unit of the speaker box disclosed in the present disclosure can be supported reliably.

Abstract: A worksite audio device includes a housing including a front side and a rear side, a speaker disposed on the front side of the housing, an audio circuit coupled to the speaker that provides an audio signal to the speaker, and an antenna assembly coupled to the housing and configured to deliver a radio signal to the audio circuit. The speaker is configured to output audio. The antenna assembly is rotatable with respect to the housing about a first axis, a second axis perpendicular to the first axis, and a third axis perpendicular to the second axis. A handle is coupled to the housing and cooperates with the housing to define a recess. A first device mount is disposed in the recess and configured to support an electronic device couplable to the audio circuit.
