Technical Field

[0001] The utility model relates to the field of audio, in particular to a multi-layer sound-generating speaker. Background Art

[0002] Audio electronics broadly refers to a device that uses electronic circuit design to convert audio and electronic signals into each other, but in general speaking, speakers usually refer to a complete set of equipment that can restore and play audio signals.

[0003] Speaker equipment generally includes power amplifiers, peripheral equipment, speakers (speakers, speakers), mixers, etc. The development history of speaker technology can be divided into four stages: electronic tubes, transistors, integrated circuits, and field effect transistors.

[0004] The sound quality of existing speakers is limited by their circuit settings and manufacturing materials. At the current stage of development, it has reached a bottleneck and it is difficult to make further progress in improving the sound quality. The sound quality of existing speakers is not powerful and lively enough, and the layering is not rich enough. Utility Model Content

[0010] Furthermore, the number of the second sound generating modules is four.

[0011] The working principle and advantages of the utility model are as follows: the multi-layer sound-emitting speaker emits sound through the woofers of each second sound-emitting module, and the sound hits the inside of the echo cover. The echo cover cooperates with the phase plug to partially reflect the sound, so that the sound collides in the echo cover, and the noise emitted by the speaker is offset, so that the sound quality of the multi-layer sound-emitting speaker is better. At the same time, the echo cover reflects part of the sound to delay the sound, and the reflected sound cooperates with the original sound, and part of the sound of the second sound-emitting module enters the box body and is then emitted from the sound-transmitting hole at the installation panel.

[0018] The following is a further detailed description through specific implementation methods:

[0019] like Figures 1 to 4 As shown:

[0020] A multi-level sound speaker, comprising a box body 1, a control unit, a first sound module 2 and a plurality of second sound modules 3, wherein the box body 1 is used to install the control unit, the first sound module 2 and the second sound module 3, the control unit is used to connect the first sound module 2 and the second sound module 3, so that an external sound source can be input to the two sound modules, an installation panel 11 is used to install the first sound module 2 and each second sound module 3, a plurality of sound holes 12 are evenly arranged at the installation panel 11, part of the sound emitted by each second sound module 3 can enter the space formed between the box body 1 and the installation panel 11, and then be emitted to the outside through the sound holes 12, so that the first sound module 2 and the sound emitted from the original cooperative sound holes 12 of each second sound module 3 work together, and finally the sound layering of the speaker is stronger; the first sound module 2 is in the middle of the installation panel 11, and each second sound module 3 is evenly installed at the installation panel 11 and each second sound module 3 is evenly surrounded by the periphery of the first sound module 2;

[0021] The first sound module 2 includes a tweeter 21 and a loudspeaker 22 . The loudspeaker 22 is mounted on the tweeter 21 . The loudspeaker 22 and the tweeter 21 are both fixedly mounted on the mounting panel 11 .

[0022] The second sound-emitting module 3 includes an echo cover 31, a fixed frame 33 and a woofer 35, and the echo cover 31 is installed on the fixed frame 33; the echo cover 31 is used to reflect part of the sound waves emitted by the woofer 35, and the fixed frame 33 is used to install the echo cover 31 on the woofer 35; the echo cover 31 is an arc-shaped structure, and a plurality of irregular sound outlet holes 32 are densely distributed on the echo cover 31; the arc-shaped echo cover 31 can evenly reflect the sound waves of the woofer 35, and the irregular sound outlet holes 32 are used for the sound of the woofer 35, as well as filtering the sound of the woofer 35, and allowing part of the sound to be transmitted to the box body 1; a phase plug 34 is provided in the middle of the inner side of the echo cover 31, and the phase plug 34 can improve the axial and off-axis frequency response of the woofer 35, so that the sound wave scattering is more uniform, the intermediate frequency is more natural, and the sound effect is better.

[0023] The control unit includes a control panel 4 and a built-in battery. The control panel 4 is electrically connected to the built-in battery, the tweeter 21, and the woofer 35. The control panel 4 is an existing mature technology, which is integrated with a charging circuit for charging the built-in battery. The control panel 4 is also integrated with an interface for connecting the tweeter 21 and the woofer 35. The control panel 4 is used to adjust the working parameters of the two speakers, and the control panel 4 is also integrated with a corresponding power amplifier function.

[0024] The number of the second sound generating modules is four.

[0025] The specific real-time process is as follows:

[0026] When using the multi-layer sound speaker, the sound source input device is connected to the control panel 4 so that the sound source input device can be connected to the tweeter 21 and the woofer 35. When the tweeter 21 of the first sound module 2 makes a sound, the sound of the tweeter 21 is amplified by the amplifying horn 22. At the same time, the woofer 35 of the second sound module 3 makes a sound, and the sound hits the inside of the echo cover 31. The echo cover 31 cooperates with the phase plug 34 to partially reflect the sound, so that the sound collides in the echo cover 31, and the noise emitted by the speaker is offset, so that the sound quality of the multi-layer sound speaker is better. At the same time, the echo cover 31 reflects part of the sound to delay the sound, and the reflected sound cooperates with the original sound. The echo cover 31 reflects part of the sound into the box 1, and this part of the sound is then emitted from the sound hole 12 at the installation panel 11 through the reflection of the box 1, so that the sound emitted by the sound hole 12 cooperates with the sound emitted by the first sound module 2 and the sound emitted by each second sound module 3, so that the sound is rich in layering and the sound is more powerful and smart.

[0027] The multi-layer sound speaker emits sound through the woofer 35 of each second sound module 3. The sound hits the inside of the echo cover 31. The echo cover 31 cooperates with the phase plug 34 to reflect part of the sound, so that the sound collides in the echo cover 31, and the noise emitted by the speaker is offset, so that the sound quality of the multi-layer sound speaker is better. At the same time, the echo cover 31 reflects part of the sound to delay the sound. The reflected sound cooperates with the original sound, and part of the sound of the second sound module 3 enters the box body 1 and is then emitted from the sound outlet 32 ​​at the installation panel 11. The sound emitted by the sound outlet 32 ​​cooperates with the sound directly emitted by the first sound module 2 and the second sound module 3, so that the sound is rich in layers and more powerful and agile.
