An acoustic transducer comprises an active element (21) which changes in length along a first axis in response to an audiofrequency input signal, the element being mounted between an inertial mass (20) and a foot (24) which in use engages a surface whereby audiofrequency vibrations produced by the active element are transmitted to the surface, characterised in that the foot is hingedly (25) connected to the inertial mass and the active element is located between the foot and the mass such that the angle between the first axis and the surface is less than 90°, in use.

Guitar bridge pins are formed of hard materials shaped to mechanically cooperate with standard guitar bridge configurations. Either molded or machined into a prescribed shape, guitar bridge pins fit into tapered shaped holes of most common guitar bridges. Guitar bridge pins of these systems include a main body portion into which a recess seat is formed. Further a string via is arranged from the recess seat to an exit aperture, the string via provides a path through which a guitar string may pass. These guitar pins provide a high-performance system for mounting and fixing guitar strings at the bridge of a standard guitar. Specifically these bridge pin devices include at least four major integrated elements including a main body, a recess seat, a string via and a stud element. Additionally, these bridge pin systems may also include cooperating spacing and locking washers which may be used in conjunction with threaded fasteners. When fastened to a guitar bridge as prescribed, these bridge pins securely couple guitar strings there to while additionally holding together a bridge assembly including the bridge plate, sound board and bridge.

Devices and methods described herein relate to novel and improved speaker assembly designs that optimize audio quality. Embodiments herein can also facilitate the tuning of audio range by linearizing frequency and amplitude. Some speaker assembly embodiments herein can improve the audio output by alternating layers of rigid and porous material, which can facilitate aperiodic resonance damping. Embodiments herein can also provide a constant audio output and improve the audio directional pattern. Moreover, speaker assemblies herein can improve the overall audio output at all frequencies by eliminating internal acoustic cavity resonance. Embodiments herein can also customize the audio output through tunable or adjustable components, such as modifying the flow resistance, density, thickness, or shape of cabinet layers. This can also shape the directional frequency response and adjust the damping or resonance frequency. Additionally, this adjustability allows assembly designs to be tailored to all different types of speakers.

A video/audio combo device includes a picture-taking element for taking pictures and a sound-generating element to output sound. It has a housing shell located in a portable electronic data processing device with the picture taking element and the sound-generating element jointly housed in the housing shell. While the picture-taking element can take pictures, the housing shell has a remained space to serve as a resonant space to enable the sound-generating element to achieve an improved audio output effect.
