A surround for protecting an acoustic device for sending and/or receiving acoustic signals positioned therein from impact as the surround is rolled along an interior surface of a fluid-containing pipeline, the surround comprising: a shell comprising an exterior segment configured to roll along the interior surface, the exterior segment defining at least one acoustic aperture configured to allow the passage of acoustic signals therethrough; and a lattice configured between the exterior segment and the acoustic device, the lattice comprising a plurality of unit cells, each unit cell defining an opening, wherein the plurality of unit cells are interconnected and define a plurality of openings, wherein the plurality of openings allow fluid to move between the interior of the surround and the exterior of the surround and enable the passage of the acoustic signals transmitted and/or received by the acoustic device such that the surround reduces the diminution of the quality and/or strength of the acoustic signals.

In at least one embodiment, a loudspeaker assembly is provided. The loudspeaker assembly includes a loudspeaker and a waveguide. The loudspeaker includes a diaphragm to transmit an audio output. The waveguide being asymmetrical and at least partially surrounding the diaphragm. The waveguide being configured to control a directivity of the audio output.

Provided is a speaker box and a mobile terminal. The speaker box is applied to the mobile terminal and includes a shell having a receiving space and a speaker unit received in the receiving space. The shell includes a bottom shell and a metal top plate covering the bottom shell and together defining the receiving space. The metal top plate includes a main body covering one end of the sidewall away from the bottom wall and a connector extending outwards from the main body. A positioning portion is provided in the connector. The housing extends toward the connector to form a heat stake supporting and fixing the connector. The connector is fixed to the housing after hot melting of the heat stake. A stable connection between the speaker box and the mobile terminal can be achieved and mounting is fast and firm.

The various implementations described herein include a camera device that includes: (1) a housing; (2) an image sensor positioned within the housing and having a field of view corresponding to a scene in the smart home environment; (3) at least one infrared (IR) illuminator positioned with the housing, the IR illuminator configured to selectively illuminate the scene; and (4) a front face that is at least partially concave-shaped and coupled to the housing, the front face positioned in front of the image sensor such that light from the scene passes through the front face prior to entering the image sensor, and the front face positioned in front of the IR illuminator such that IR light from the IR illuminator is directed through the front face.

Provided is a balanced armature type speaker. The balanced armature type speaker includes a housing, a driving assembly and a diaphragm. The housing includes an upper inner cavity and a lower inner cavity, the lower inner cavity and the upper inner cavity are through from top to bottom, the driving assembly is located in the lower inner cavity, and the driving assembly includes a magnet, a coil, an armature and an ejector pin. The armature is inserted into the magnet and the coil sequentially, the ejector pin is fixedly connected to the armature and the diaphragm, and the diaphragm is located in the upper inner cavity. The housing is shaped to be wide at the upper part and narrow at the lower part, and in the horizontal direction, a width of the upper inner cavity is larger than a width of the lower inner cavity.

A vehicle assembly includes a panel or mounting location, a speaker or microphone disposed within the panel for generating or detecting sounds and a cover disposed over the speaker. The cover includes a plurality of openings for the transmission of sound and a corresponding plurality of blockers at each of the plurality of openings. Each of the plurality of blockers includes a front face that is spaced apart forward of a corresponding one of the plurality of openings for blocking water intrusion.

Embodiments describe an eartip including an eartip body having an attachment end and an interfacing end opposite from the attachment end. The eartip body can include an inner eartip body having a sidewall extending between the interfacing end and the attachment end, the sidewall defining a channel and having a first thickness near the attachment end and a second thickness different from the first thickness at the interfacing end. The eartip can also include an attachment structure coupled to the inner eartip body at the attachment end, the attachment structure having an inner surface and an outer surface. The attachment structure can include an upper region interfacing with the sidewall and defining discrete through-holes, a lower region below the upper region where the inner surface defines a plurality of recesses positioned around the lower region, and a mesh extending across the channel and into the upper region.

A mesh assembly includes a mesh cover, and a stiffener configured to fix a position of the mesh cover, wherein the stiffener includes a body and an arm extending from the body, and wherein the arm includes a bending portion having an internal diameter of about 0.3 mm or more.
