Abstract: Systems and methods relate to, among other things, a transducer capable of producing acoustic and tactile stimulation. The transducer includes a rigid mass element disposed on the diaphragm of a speaker. The mass element may optionally be removable and may have a mass selected such that the resonant frequency of the transducer falls within the range of frequencies present in an input electrical audio signal. The systems and methods advantageously benefit from both the fidelity and audio performance of a full-range speaker while simultaneously producing high-fidelity, adjustable and palpable haptic vibrations.

Abstract: A headphone includes a housing and a speaker device. The speaker device includes a woofer and a tweeter. The woofer includes a first frame, a first magnetic circuit unit, and a first vibration unit. The tweeter includes a second frame, a second magnetic circuit unit, and a second vibration unit. The first magnetic circuit unit includes an auxiliary magnet close to the second vibration unit. The second magnetic circuit unit includes a central magnet fixed to the second frame and side magnets located at a periphery of the central magnet. A magnetizing direction of the auxiliary magnet and a magnetizing direction of the central magnet are opposite and are arranged along a vibrating direction. Magnetizing directions of the side magnets each point to the central magnet. The speaker device can better satisfy requirements of markets on the size and sound production performance of the headphone.

Abstract: A through hole is formed in an inner-side yoke making up a magnetic circuit portion, passing therethrough following a vibration direction of a vibration unit, and circuit boards are disposed in the through hole. The circuit boards are disposed with board surfaces thereof following the vibration direction of the vibration unit. Also, an opening area of a middle space across which the circuit boards oppose each other is larger than opening areas of side spaces. Accordingly, flow quantity of air through the through hole can be obtained, increase in air resistance at the time of vibration of the vibration unit can be suppressed, and also wind velocity can be obtained, whereby cooling effects of heat-generating components mounted on the circuit boards can be improved.

Abstract: An amplification system which includes a source of electrical audio signals, a first amplifier, a second amplifier, a plurality of loudspeakers, and a first phase of the first amplifier and a second phase of the second amplifier reproduced in parallel having a time delay between first and second phase amplification for out of phase correction. The time delay is configured to correct poor sound signals while amplifying weaker harmonics and sound signals of different frequencies, thereby adjusting sound output of the amplification system and acoustical characteristics of a room. The amplification system is useful for providing improved sound quality and increased audio efficiencies.

Abstract: The present disclosure provides a speaker, including a frame, a vibration system, a magnetic circuit system, the vibration system includes a first diaphragm and a second diaphragm which are fixed to two opposite sides of the frame, a first voice coil to drive the first diaphragm to vibrate, and a second voice coil assembly to drive the second diaphragm to vibrate. The vibration system further includes a first elastic wave assembly and a second elastic wave assembly which are fixed to the frame and are spaced from each other. The first elastic wave assembly and the second elastic wave assembly are in staggered distribution and antiphase vibration. By means of the staggered distribution of the first elastic wave assembly and the second elastic wave assembly, the first elastic wave assembly and the second elastic wave assembly make reasonable use of an internal space of the speaker.
