摘要： A speaker assembly broadly comprising a housing, an input circuit, and a number of speakers. The housing includes a lower section configured to be positioned at least partially below a ground surface and an upper section extending upwards from the lower section. The input circuit receives audio signals from a sound system or other controller and actively or passively sends the audio signals to the speakers. The speakers include a low-range speaker positioned in the lower section of the housing and a relatively higher-range speaker positioned in the upper section. The speaker assembly is configured to be spaced from other speaker assemblies within a listening area with each speaker assembly generating low frequency soundwaves and relatively higher-frequency soundwaves. This reduces or eliminates out-of-phase crossover frequency wave cancellation effects within the listening area.

摘要： A loudspeaker unit includes a voice coil, a diaphragm, a damper, a frame supporting an outer edge of the diaphragm and an outer edge of the damper, and a duct projecting from an outer surface of the frame, with air moved by vibration of the diaphragm flowing into and out of the loudspeaker unit through the duct. The frame has an aperture that communicates with a space inside the frame. The duct, serving as a separate member, is attached to the frame so as to cover the aperture. The frame further includes a support tab that projects into the aperture. Link terminals are attached to the support tab. Before the duct is attached to the frame, lead wires extending from the voice coil are formed into a predetermined shape and are then connected to the link terminals in a space within the aperture.

摘要： The present invention discloses a miniature loudspeaker module, a method for enhancing frequency response of a miniature loudspeaker module, and an electronic device. The method comprises the steps of: additionally providing a passive driver in a cavity where an active driver of a miniature loudspeaker module is located, the passive driver and the active driver radiating together, wherein, after the passive driver is additionally provided in the miniature loudspeaker module, the amplitude of a vibrating diaphragm of the active driver shows a local dip on frequency bands below a resonant frequency point F0, and the lowest point of the local dip is corresponding to a frequency point Fb; and, perform, according to amplitude characteristics of the vibrating diaphragm of the active driver of the miniature loudspeaker module additionally provided with the passive driver, matching enhancement to an input signal of the active driver. In the technical solutions provided by the present invention, as the frequency response of the whole miniature loudspeaker module on low frequency bands below F0 is enhanced after a passive driver is additionally provided, and matching enhancement is further performed to signals according to the amplitude characteristics of the active driver, the frequency resource of the miniature loudspeaker module on the whole frequency band is enhanced greatly.

摘要： The present invention relates to a loudspeaker (1). The loudspeaker (1) includes: a U-yoke for holding a magnet having a base (12) with an upstanding side (14) around the perimeter of the base (12); a frame (20) having a ring (22) around the U-yoke, the ring having a U-shaped cross-section orientated with a base (24) of the U abutting the side (12) of the U-yoke; a dome shaped diaphragm (40) connected to the frame (20) by a resilient member (30) around the dome (40), the resilient member (30) and the dome (40) being suspended from the frame (20); a first cavity (70) defined by the dome (40), resilient member (30), frame (20) and U-yoke; an external wall (80) around the circumference of the frame (20), the external wall (80) sealing a top of the U-shaped cross-section of the ring (22) forming a second cavity (100) between the external wall (80) and the ring (22); a port (110) in the frame (20) between the first cavity (70) and second cavity (100), wherein the first cavity (70) and second cavity (100) and the port (110) form a Helmholtz resonator system. The shape of the frame (20) in combination with the external wall (80) allows a Helmholtz resonator system to be established within the existing footprint of the loudspeaker.
