Provided is a speaker box, including: an upper cover, an upper steel sheet; a lower cover, a lower steel sheet; a receiving space, an acoustic unit; and an insert plate arranged in the rear cavity. Upper and lower sides of the insert plate abut against the upper steel sheet and the lower steel sheet, respectively, a position of at least one of the upper steel sheet or the lower steel sheet aligned with the insert plate is provided with a fixing groove passing therethrough, and the insert plate is fixed to at least one of the upper steel sheet or the lower steel sheet through glue injection in the fixing groove. The speaker has characteristics of convenient mounting, good anti-shell vibration effect, and reduced mounting space.

The methods, systems and devices provided herein relate to sleep-aid. Some embodiments include a vibration source and/or a sound source. In some embodiments, the vibration source and/or sound source emit vibrations and/or sounds that stimulate a subject's vagus nerve, or another nerve, to induce sleep or relaxation in the subject.

A flat plate audio transducer. A front panel and a back panel are connected via a frame. One or more electromagnetic actuators are mounted between the two panels. Voice coils are used as the actuators in some embodiments. Stiffening braces are preferably run between groups of actuators to prevent unwanted resonance phenomena. In some embodiments an actuator array moves both the front and back panels. In other embodiments only one panel is moved.

A speaker assembly broadly comprises an inner housing, an outer shell, an input circuit, and a speaker. The inner housing includes outer shell attachment structure and a lower press-fit outer surface and forms a central chamber retaining the input circuit and the speaker. The outer shell includes a primary enclosure and a lower cap. The primary enclosure includes inner housing attachment structure configured to align with and engage the outer shell attachment structure. The primary enclosure is configured to be press-fit to the inner housing via the lower press-fit outer surface of the inner housing. The lower cap encloses a bottom end of the central chamber. The outer shell is interchangeable with other outer shells having different shapes than the outer shell of the speaker assembly.

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 example speaker for providing alerts includes: a housing and a cover forming an integrated unit; a microphone configured to sense an ambient noise level; and a processor configured to adjust a volume of the speaker based upon the ambient noise level. A hinge can be positioned between the housing and the cover to allow the cover to be pivoted relative to the housing from a close position to an open position.

Provided is a cover member for an electronic device, the cover member having a through hole extending between a first surface and a second surface. The cover member for an electronic device includes a plurality of long particles that are present in an inner wall facing the through hole and whose longitudinal direction is along a through axis of the through hole in a cross section including the through axis.

A sound generating device comprises top, bottom and sound generating assemblies. The sound generating assembly comprises a microprocessor, sound chip, capacitor, speaker and power source that are electrically interconnected. The sound can range from animal and/or environmental sounds, music, congratulatory messages, other types of voice recordings, bells, whistles and the like, and the length of play can be varied. When the device is struck against a hard surface, the contact in the top is depressed and interacts with a receptor on the sound generating device to communicate with the microprocessor and sound chip to generate a sound, which can persist from about one or more seconds, depending on how the sound generating device had been programmed. Repeat strikes of the sound generating device against the surface will result in a repetition of the sound.

A covering structure disposed within a sound producing package includes a first portion, a second portion and a third portion. The first portion is configured to form a first sound outlet having a first diameter. The second portion is configured to form a chamber having a second diameter. The third portion is configured to form a second sound outlet having a third diameter. Wherein, the first sound outlet, the chamber and the second sound outlet provide an acoustic pathway, the first diameter is smaller than the second diameter, and the third diameter is smaller than the second diameter; and wherein, the second portion is disposed between the first portion and the third portion.

A system and method for creating a sealed enclosure for a loudspeaker in a vehicle body portion of a vehicle are provided, the vehicle body portion including an inner body panel having a first internal surface and an outer body panel having a second internal surface, wherein the inner body panel and the outer body panel are spaced apart to define a cavity therebetween. The system includes at least one insert member arranged to be received within the cavity and coupled to the first internal surface and the second internal surface to partition the cavity and create the sealed enclosure for the loudspeaker.
