Furthermore, when the sound basin vibrates, it only drives part of the air around it to vibrate, and the rest of the air that does not participate in the vibration creates resistance around the sound basin, causing the sound basin to twist when it vibrates, causing the confusion of the three sounds in the music. Reduced quality of music sound

Embodiment 1

[0019] The three different frequency components of high frequency, intermediate frequency and low frequency in the audio signal constitute the treble, midrange and bass in the music respectively. The treble is transmitted from the area near the mouth of the speaker cone, which is the treble area, and the bass is transmitted from the area close to the bottom of the speaker cone, which is the bass area, and the midrange is from the bottom of the speaker cone. The middle area comes out, which is the mid-range area.

[0020] FIG. 1 is a three-dimensional schematic diagram of a sound cone in Embodiment 1 of the loudspeaker of the present invention. As shown in FIG. 1 , the embodiment of the present invention provides a loudspeaker including a sound cone 11 on which three holes are provided, and an enlarged schematic view of one of the holes 12 is given. By setting holes on the sound cone, when the music sound wave reaches the sound cone, the air that does not participate in the vi...

Embodiment 2

[0026] Fig. 3 is an enlarged schematic view of the holes in the second embodiment of the speaker of the present invention. As shown in Figure 3, on the basis of Embodiment 1, the embodiment of the present invention is provided with a folded body 33 on the inner surface 31 of the sound cone. The folded body 33 corresponds to the position of the hole 12, and the folded body 33 is generally conical. structure, the folded body 33 includes an integral folded piece or several split folded pieces. The lower edge of the folded body 33 is connected to the edge formed by the hole 12 on the inner surface 31 of the sound cone, and the side of the folded body 33 forms an obtuse angle with the inner surface 31 of the sound cone. Fig. 3 is only an enlarged view of a hole 12 in the sound basin, and the inner surface of the sound basin corresponding to the remaining holes in the sound basin is also provided with a folded body.

[0027] The folded body can be formed while the hole is set, or c...

Abstract

The invention relates to a loudspeaker. The loudspeaker comprises a cone which comprises a high tone area, a medium tone area and a low tone area. The high tone area of the cone is provided with high tone holes inside; the medium tone area of the cone is provided with medium tone holes inside; and the low tone area of the cone is provided with low tone holes inside. Furthermore, the cone bottom is positioned in a triangular area formed by the projection of the high tone holes, medium tone holes and low tone holes on the plane of the cone bottom. Still further, turnover bodies can be arranged on the inner surface of the cone corresponding to the positions of the holes. The cone in the loudspeaker is improved; the different areas of the cone are provided with the holes inside; the turnover bodies are further arranged on the inner surface of the cone corresponding to the holes. Therefore, the synchronization of the high tone, the medium tone and the low tone is realized; the musical sound given off by the loudspeaker becomes smoother; and the overtone effect is simultaneously produced.

Description

technical field [0001] The invention relates to a loudspeaker, in particular to a loudspeaker capable of improving sound quality. Background technique [0002] With the development of the times, the level of people's appreciation of music is gradually improving, and the requirements for sound quality are also getting higher and higher. There are many ways to enjoy music, including concerts, home audio, and walkmans. Most of the music you enjoy is obtained through the speakers in the audio equipment. Therefore, the quality of the speakers directly affects the effect of the music; however When music is transmitted from the speaker to the human ear, the sound waves must be transmitted through various components in the speaker. When the components of the speaker work, energy loss will inevitably occur, which will cause damage to the sound quality. In order to obtain better sound quality, it is necessary to minimize the external speaker. The loss caused by playing music. [000...
