Abstract

The invention relates to a structure of a loud speaker device, which comprises the following steps: a plank frame and square beams arranged around the edge of the plank frame are used for supporting; a hollow low sound louder speaker jolting plate is arranged; the interior of the plank frame is provided with a magnet; the upper part and the lower part of the magnet are respectively provided with a front plate electrode and a rear plate electrode that form a field circuit together with a pole piece; an interval is retained between the pole piece and the front plate electrode; a coil former is arranged in the interval, surrounds the hollow circumference of the low sound louder speaker jolting plate and is entwined with a voice coil; a vibration plate of an intermediate cover is positioned at the hollow position of the low sound louder speaker jolting plate and supported by square beams of a coupler. According to the structure, the invention achieves the effects of sharing the field circuit, causing the low sound louder speaker jolting plate and the vibration plate of the intermediate cover to run, having the loud speaker device with a simple structure, promoting reliability and reducing production cost through sharing the field circuit.

Description

technical field [0001] The present invention relates to the structure of the loudspeaker device, especially on the loudspeaker device for playing low-frequency and intermediate-frequency sound waves. The operating coupling edge makes the structure of the loudspeaker device simple and reduces the production cost of the loudspeaker device. Background technique [0002] Generally, for home theater speakers with a built-in audio device, the speaker device is set to play sound waves through the operation of the vibrating plate. However, the above-mentioned speaker devices can be divided into low-frequency playable sound range-300Hz sound wave woofer device, intermediate cover speaker device play intermediate frequency 300Hz-2KHz sound wave, and high-frequency 2KHz-playable sound range high-frequency speaker device according to the sound range to be played. , but their structure is similar. [0003] figure 1 It is a cross-sectional view showing the structure of a conventional s...
