Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a speaker with high sound reproduction. Background Art

[0002] The speaker is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into space.

[0003] The main components of a speaker are the speaker and the motherboard. The speaker is used to convert the electrical signal of the motherboard into sound. Some speakers are also equipped with a passive plate (also called a passive membrane), which can help enhance the low-frequency response of the speaker. Through the resonance effect during low-frequency vibration, it can increase the bass extension of the speaker and produce richer low-frequency effects, providing a deeper bass sound. The presence of the passive plate can reduce the distortion of the speaker and improve the sound quality. However, in the prior art, the passive plate and the speaker are installed on the speaker housing. The vibration of the passive plate and the speaker easily drives the housing to resonate, causing the propagation of sound in the speaker to be disordered, and then howling occurs. Especially in an integrated speaker microphone device, since the device shakes with the hand, the connection between the passive plate and the speaker and the housing is unstable, and the housing is more prone to irregular vibration, so it is more likely to produce howling, and at the same time, the sound restoration is reduced.

[0004] Therefore, it is necessary for the inventor to design a new speaker with high sound reproduction to overcome the above problems. Summary of the invention

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] like Figures 1 to 5 As shown, a sound box with high sound effect restoration includes an outer shell 1, two speakers 3 are relatively fixedly installed inside the outer shell 1 through two first brackets 2, and two passive plates 5 are symmetrically fixedly installed through two second brackets 4. A first vibration reduction component is fixedly installed between the two speakers 3 and the outer shell 1, and a second vibration reduction component is fixedly installed between the two second brackets 4 and the outer shell 1; the first vibration reduction component includes a first sealing ring 6 and a second sealing ring 7, the first sealing ring 6 is fixedly arranged between the first bracket 2 and the outer shell 1, and the second sealing ring 7 is fixedly arranged between the speaker 3 and the first bracket 2; the first sealing ring 6 and the second The sealing ring 7 is made of EVA; the second vibration reduction component is a vibration reduction gasket 8, and a limit component is fixedly arranged between the second bracket 4 and the outer shell 1; during operation, when the speaker 3 makes a sound, the sound is transmitted to the passive plate 5 in the speaker box, the passive plate 5 resonates, and the speaker 3 vibrates. Since the first sealing ring 6 and the second sealing ring 7 made of EVA material have a good vibration reduction effect, most of their vibrations are absorbed by the first sealing ring 6 and the second sealing ring 7, which greatly reduces the vibration transmitted to the outer shell. Similarly, most of the vibrations of the passive plate 5 are absorbed by the vibration reduction gasket 8, so the vibration amplitude of the outer shell 1 and the probability of howling are greatly reduced, thereby improving the degree of sound restoration.

[0033] The limiting assembly includes a mounting opening 9 and a plug-in board 10, wherein the mounting opening 9 is provided on the outer shell 1, the plug-in board 10 is fixedly arranged on the second bracket 4, the plug-in board 10 has a pressing ring 11 and a buckle 12, the plug-in board 10 is plugged into the mounting opening 9, the pressing ring 11 and the buckle 12 are respectively abutted against the outer surface and the inner surface of the outer shell 1, and the vibration-damping gasket 8 is arranged between the outer surface of the outer shell 1 and the pressing ring 11; when working, the plug-in board 1 0 is annular, the vibration-damping gasket 8 is sleeved on the outer wall of the plug-in board 10 and contacts the pressure ring 11, and then the plug-in board 10 is inserted into the installation port 9. The buckle 12 has a guiding inclined surface for facilitating the insertion of the plug-in board 10. After being fully inserted, the outer shell 1 is clamped between the buckle 12 and the pressure ring 11. At the same time, the vibration-damping gasket 8 is compressed and in a working state. The rigid contact between the outer shell 1 and the second bracket 4 is only the contact between the buckle 12 and the outer shell 1. The vibration effect transmitted is weak and it is not easy to produce howling.

[0034] The two speakers 3 are arranged on the outer shell 1 opposite to each other, and the angles between the central axes of the two speakers 3 and the horizontal line are different; the angle between the central axes of the two speakers 3 is 10-30°; the central axis of one of the speakers 3 is parallel to the horizontal line, and the angle between the central axis of the other speaker 3 and the horizontal line is 10-30°, which can be 10°, 15°, 20°, 25°, or 30°; when working, if the two speakers 3 are symmetrically arranged, the sounds they transmit will be negatively offset, reducing the volume of the sound, and at the same time causing sound distortion. Therefore, the two speakers 3 are deviated from a certain angle to reduce the sound offset effect and improve the degree of sound restoration. After experiments, the angle between the central axes of the two speakers 3 is set to 10-30°. If the angle is too small, the sound will still be largely offset. If the angle is too large, the coordination of the sounds of the two speakers 3 will be greatly reduced, and the sound effect will be poor. 10-30° is more appropriate.

[0035] The two speakers 3 and the two passive panels 5 are spaced apart on the outer shell 1; when working, the passive panels 5 are arranged on both sides of the line connecting the two speakers 3, so that the passive vibration effects of the two passive panels 5 are more coordinated and the sound quality of the sound transmitted from the speaker box is better.

[0036] It also includes a speaker cover 13 and a circuit main board 14, the speaker cover 13 and the circuit main board 14 are respectively fixedly connected to the top and bottom of the outer shell 1, and sealing strips are fixedly arranged between the speaker cover 13, the circuit main board 14 and the outer shell 1; when working, the top of the speaker is used to install the sound receiving tube of the microphone, and the lower part of the speaker is used to install the handheld part of the microphone. The sealing strip can reduce the sound energy of the sound in the speaker from the speaker cover 13 and the circuit main board 14 to the outer shell to make the outer shell resonate, thereby reducing the occurrence rate of howling and improving the sound restoration.

[0037] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
