Ultra thin type depth base tone loudspeaker with touch sensation shaking feeling

Abstract

The invention relates to a generating device of sound and vibration, in particular to a deep woofer with vibrating touch, which belongs to the manufacturing field of the amplifier. The invention is composed of a case, magnetic steels, an iron based square section podetium, a coil and a vibrating wing plate. The invention is characterized in that the iron based square section podetium is arranged in the middle of the case, an upper and a lower end faces are connected with an upper-and-lower vibrating wing plate systems by a non iron based podetium, and the diameter of the non iron based podetium is smaller than that of the iron based square section podetium. Four magnetic steels with equal sizes are correspondingly arranged at the peripheries of the iron based square section podetium. One end of magnetic steel is fixed on the inner wall of the case of an iron based square, and the upper and the lower parts of the case are connected with the vibrating wing plate system. A surface of the iron based square section podetium which faces the four magnetic steels is provided with the coil. The invention has the advantages of simple structure, convenient process, low cost and visible vibrating effect.

Description

Background of the invention [0001] The invention relates to a sound and vibration generating device, in particular to a deep subwoofer with a sense of tactile vibration, which belongs to the field of speaker manufacturing. [0002] Sound is actually a kind of vibration. People can feel it when listening to sound, but this kind of vibration is relatively weak. Sometimes it is necessary to convert sound into more obvious vibration so that people can feel it more clearly. The most typical is The sound conversion device designed for the deaf-mute, such as the Chinese patent bone conduction vibrator with the patent number 00819928.0, now, in order to allow people to feel the music through the sense of touch and the vibration of the body while listening to music, it is also necessary to design a The sound sensor allows people to hear the sound and feel the vibration through the body. There are already such products on the market, such as I BEAMVT300 Vibro Tactile Transducer. The sch...

Problems solved by technology

When a current is passed into the coil passed by the magnetic flux, the current interacts with the magnetic flux, causing the magnet to move in the vertical direction. When a strong audio current is passed into the coil, the magnet will synchronously produce up and down. , strong and weak different vibrations, drive the vibrating wing plate system at the upper and lower ends of the figure, and output tactile deep bass audio frequency vibrations to the appliance (such as a sofa) that is in contact with the sensor and the human body that is in contact with the appliance. Vibration again! However, the main disadvantage of this technology is that the height of the entire sensor is too high, which is not conducive to the proper location of the device to external appliances such as sofas; the second is that the magnetic circuit is too long and the magnetic efficiency is low

These disadvantages stem from the unreasonable layout of the magnetic system
