Problems solved by technology

However, the thick paper cone, larger speaker diameter, larger magnet diameter and voice coil diameter will undoubtedly increase the cost of the speaker, and simply through this thickening and growth method, the woofer needs more driving power to work.
And the above-mentioned improvements are more concerned with improving the vibration of the paper cone and voice coil. By adding additional devices such as the above-mentioned passive plate structure, it can only amplify the low-frequency volume, and does not fundamentally improve the audio quality.
Therefore, the improvement of the traditional woofer does not give a solution to effectively improve the sound quality of the woofer simply by increasing the stroke of the voice coil

Embodiment Construction

[0035] Such as Figure 2 to Figure 3 As shown, the loudspeaker according to the first preferred embodiment of the present invention includes a magnetic return system 10, a voice coil 20 and a first drum paper 30 and a second drum paper arranged on both sides of the magnetic return system 10 respectively. 40.

[0036] The magnetic return system 10 is used to provide a magnetic field to the loudspeaker, and its structure can be the magnetic return structure of a traditional loudspeaker. As an example, as a magnetic return system 10 with a permanent magnet and a magnetically conductive core post, the permanent magnet can be a ring structure, that is, A permanent magnetic ring, or a plurality of magnets spaced around each other. The permanent magnet generates a magnetic field, and forms a sound source assembly together with the voice coil 20 through the magnetic core column.

[0037] The voice coil 20 is in the magnetic field of the magnetic loop system 10 and vibrates under the...

Abstract

A loudspeaker comprises a magnetic loop system, a first paper cone, a second paper cone and a voice coil, wherein the first paper cone and the second paper cone are arranged on two sides of the magnetic loop system respectively; and the voice coil is connected to the first paper cone and the second paper cone, and vibrates under the action of a magnetic field provided by the magnetic loop system so as to drive the first paper cone and the second paper cone to vibrate to enable the loudspeaker to make a sound. According to the loudspeaker, the voice coil is connected to the two paper cones and the stroke of the voice coil is enlarged, therefore the utilization rate of the output power of the loudspeaker is high, and the loudspeaker is particularly suitable for providing a high-quality bass effect.

Description

technical field [0001] The invention relates to a loudspeaker, in particular to a loudspeaker equipped with two drum papers and lengthened voice coil stroke. Background technique [0002] The working principle of a typical loudspeaker is that the permanent magnetic material generates a magnetic field in the annular air gap of the magnetic circuit through the yoke, and the voice coil connected to the speaker drum is inserted into the annular air gap. When the sound passes through the magnetic field in the form of current At this time, the coil will vibrate at different frequencies due to changes in the strength of the current, and then drive the drum paper to emit sounds of different frequencies and strengths. [0003] According to different frequency ranges, speakers can be divided into tweeters, midrange speakers and woofers. The position of bass in music is very important. When a piece of music has a strong bass step, it can feel very grand and powerful, with a strong sen...
