A speaker and like manufactured item manufacturing system, apparatus and method for aligning speaker components regardless of feature size to a common centering datum for placement. A speaker motor assembly may be aligned based on datum of a basket/washer subassembly, wherein remaining components are coupled, aligned and adhered according to the same datum, thus increasing concentricity, alignment, and orthogonality among components and installations. Speaker suspension components may likewise be coupled using the same datum. Specialized alignment mechanisms, such as a centering collet and a mechanical gripper, may be also be provided to align speaker components for placement and adhesion, and adhesives may be robotically controlled based on the aforementioned datum.

In examples, an electronic device comprises a first speaker port, a second speaker port, and storage comprising a first port attribute corresponding to the first speaker port and a second port attribute corresponding to the second speaker port. The storage comprises executable code. The electronic device comprises a processor coupled to the first and second speaker ports and the storage. The processor, upon executing the executable code, is to collect ambient noise data using a first speaker corresponding to the first speaker port in response to the first port attribute indicating that the first speaker is to be used as a microphone and the second port attribute indicating that a second speaker corresponding to the second speaker port is to be used as a speaker. The processor is to modify an audio output signal using the ambient noise data collected using the first speaker. The processor is to provide the modified audio output signal to the second speaker port.

A rear side of a vibration part of a speaker is covered by a cover member, and a duct is provided at the cover member. The cover member has a recessed portion, and an air flow path is formed inside the recessed portion. A circuit part is mounted on an outer surface of the cover member, and a heat sink provided in the air flow path is connected to the circuit part to allow heat conduction. Due to vibration of the vibration part, an airflow in the air flow path is accelerated and thus the effect of dissipating heat from the heat sink is increased.

A speaker assembly, and a display device including the same are provided. The speaker assembly according to an aspect of the present disclosure includes: a pair of magnets facing each other; a bobbin disposed between the pair of magnets and formed in a shape of a plate that extends long; a coil formed on at least one surface of the bobbin; a diaphragm fixed to one side of the bobbin, and extending in a direction intersecting a longitudinal direction of the bobbin; a frame disposed between the pair of magnets and the diaphragm; and a speaker edge disposed between the frame and the diaphragm, having one end fixed to the frame and the other end fixed to the diaphragm, and being convexly curved toward the bobbin.

An acoustic diaphragm 1 according to the present invention includes a center dome member, and a sub dome member. The center dome member includes a center dome 2 and an annular first plane part 2a that is disposed along the outer periphery of the center dome and formed integrally with the center dome. The sub dome member includes a sub dome 3 and an annular second plane part 3a that is disposed along the inner periphery of the sub dome and formed integrally with the sub dome. The first plane part includes a rising part 2b of the center dome, a first front surface, and a first back surface. The second plane part includes an inner peripheral edge 3b, a second front surface, and a second back surface. The center dome is formed of a material different from that of the sub dome. The sub dome surrounds the periphery of the center dome. The inner peripheral edge coincides with the rising part. The first front surface is joined to the second back surface.

A sounding device includes a frame, and a vibration system and a magnetic circuit unit that are retained in the frame. The vibration system includes diaphragm and voice coil. The voice coil includes two first side edges and two second side edges. The magnetic circuit unit includes yoke, main magnetic body, and auxiliary magnetic body. The auxiliary magnetic body includes first auxiliary magnetic bodies each including main body portion and extension portion. The main body portion is recessed towards side surfaces of two first side edges to form grooves, the main magnetic body protrudes towards the grooves, and the pair of first side edges protrude towards the grooves, respectively. The sounding device can not only enable the auxiliary magnetic body to be more evenly surrounding the voice coil, but also enable the voice coil to have longer circumference with a same magnetic circuit area, thereby increasing BL value.

Provided is a speaker device, including a frame; a vibration unit fixed to the frame; and a magnetic circuit unit driving the vibration unit to vibrate and produce sound and including a magnetic gap. The vibration unit includes a diaphragm, a voice coil and an elastic support assembly. The frame includes a bottom wall and a side wall bending and extending from a periphery of the bottom wall of the frame, and an outer periphery of the diaphragm is fixed to the side wall. The vibration unit further includes a fixing ring configured to fix the elastic support assembly to the frame, and the fixing ring surrounds the magnetic circuit unit. The frame is made of a metal material, and the fixing ring is a metal ring fixed to the side wall of the frame by welding. With this structure, overall strength and reliability of the speaker device are improved.

Provided is a speaker, including a frame; a vibration unit fixed to the frame; and a magnetic circuit unit driving the vibration unit to vibrate and provided with a magnetic gap. The vibration unit includes a diaphragm fixed to the frame and a voice coil inserted in the magnetic gap to drive the diaphragm to vibrate and produce sound; an outer periphery of the diaphragm bends and extends to form at least one fixing portion; and the at least one fixing portion extends along a vibrating direction of the diaphragm and is attached to an inner peripheral side of the frame. With this structure, the bonding strength of the frame and the diaphragm is improved, the diaphragm does not occupy an outer space of the frame, and an appearance size of the speaker is effectively controlled, thereby facilitating the miniaturization design.

A vibrating unit includes a diaphragm and a bobbin, and a voice coil is secured to the bobbin. A detecting unit includes a moving magnet and a magnetic sensor. An annular magnet support is secured to a front edge of the bobbin, and the moving magnet is positioned and secured to the magnet support. The magnetic sensor is secured to a drive supporting unit. The moving magnet is secured to the bobbin, with the magnet support therebetween. This facilitates mounting and positioning of the moving magnet.

The electrical device is an electrical device that is mounted on a wall of a building, the electrical device including: an actuator that vibrates; and absorbing member that absorbs vibration of the actuator and is positioned behind the actuator in a predetermined direction, where a direction from a back side to a front side of the wall is defined as a direction toward a front in the predetermined direction in a state where the electrical device is mounted on the wall.
