Description

Technical Field

[0001] The utility model relates to the technical field of speakers, and particularly relates to a speaker with good sound amplification effect. Background Technique

[0002] A speaker is a device that converts electrical signals into sound signals and is an extremely important component of an audio system. It uses a built-in power amplifier in the box to amplify the audio signal and then plays back the sound through the speaker itself to make the sound louder. For example, the patent document with the Chinese patent application number 202323598088.5 and the publication date of August 6, 2024, discloses a new type of detachable speaker, including: a fixing frame, in which a plurality of equally spaced audio bodies are arranged; a connecting mechanism; by setting an installation component, the spline shaft is rotated to drive the toothed plate to rotate, and then the toothed plate drives the clamping plate to be retracted into the movable groove, and then the audio body and the mounting plate are placed into the fixing frame.

[0003] For the existing speakers such as this document, they only set the speakers on one side of the box body, and the sound emitted by the speakers has directivity. However, this easily makes the sound not easily spread to every position around, resulting in a smaller sound behind the speakers and poor sound amplification effect of the speakers. Summary of the Invention

[0004] The utility model provides a speaker with good sound amplification effect, so that the sound emitted by the speaker can spread around the speaker, thereby making the sound amplification effect of the speaker good.

[0005] To achieve the above object, the utility model provides a speaker with good sound amplification effect, including a speaker main body. A speaker mounting hole is provided at the center of the speaker main body, a speaker is provided in the speaker mounting hole, a sound amplification cavity is provided in the speaker main body, one or more sound inlet holes penetrating through to the speaker mounting hole are provided on the inner wall of the sound amplification cavity close to the speaker mounting hole, and the sound inlet holes communicate the speaker and the sound amplification cavity; one or more sound outlet holes penetrating through to the outside of the speaker main body are provided on the inner wall of the sound amplification cavity close to the outer side wall of the speaker main body, the sound outlet holes are arranged in a circular array along the outer side wall of the speaker main body, and the sound emitted by the speaker enters the sound amplification cavity through the sound inlet holes, and after being mixed in the sound amplification cavity, it is transmitted to the outside of the speaker main body through the sound outlet holes.

[0006] With the above settings, an air inlet is provided on the side wall of the sound amplification cavity close to the speaker mounting hole. Then, the sound emitted by the speaker enters the sound amplification cavity through the air inlet for mixing, and then passes through more than one sound outlet arranged in a circular array along the outer side wall of the speaker body. As a result, the sound outlets are located in the 360-degree direction of the outer side wall of the speaker body. When the sound emitted by the speaker is transmitted through the sound outlets, the sound can be propagated in the 360-degree direction of the speaker body, enabling the sound emitted by the speaker to spread around the speaker. After mixing in the sound amplification cavity, the sounds of different frequency bands emitted by the speaker are mixed, resulting in a good sound amplification effect for the speaker.

[0007] Furthermore, there are two or more air inlets.

[0008] With the above settings, more sound emitted by the speaker can enter the sound amplification cavity better.

[0009] Furthermore, the outer side wall at the upper end of the speaker body is arc-shaped upward and inward.

[0010] With the above settings, due to the arc-shaped outer side wall, the sound outlets have a certain angle, enabling a larger range of sound emitted through the sound outlets.

[0011] Furthermore, the side wall of the speaker mounting hole is arc-shaped upward and outward.

[0012] With the above settings, it is convenient to install the speaker.

[0013] Furthermore, two or more air inlets are evenly spaced along the circumferential direction of the speaker mounting hole on the inner wall of the sound amplification cavity.

[0014] With the above settings, the sound emitted by the speaker at different angles can enter the sound amplification cavity better for mixing.

[0015] Furthermore, the cross-sectional area of the upper end of the speaker body is smaller than that of the lower end of the speaker body.

[0016] With the above settings, the upper end of the speaker body can be inclined inward while ensuring that the sound amplification cavity has a certain area.

[0017] Furthermore, the sound outlets are located in the middle of the outer side wall at the upper end of the speaker body.

[0018] With the above settings, the sound outlets can reach a wider range.

[0019] Furthermore, the air inlets are located at the bottom of the inner side wall of the sound amplification cavity close to the speaker mounting hole.

[0020] With the above settings, more sound emitted by the speaker can enter the sound amplification cavity. Brief Description of the Drawings

[0024] The present utility model will be further described in detail below in conjunction with the accompanying drawings and the detailed description of the preferred embodiment.

[0025] As Figures 1-3 shown, a speaker with good sound amplification effect includes a speaker main body 1. A speaker mounting hole 2 is provided at the center of the speaker main body 1. A speaker (not shown in the figure) is provided in the speaker mounting hole 2. An amplification cavity 11 is provided in the speaker main body 1. An inlet port 12 penetrating through to the speaker mounting hole 2 is provided on the inner wall of the amplification cavity 11 close to the speaker mounting hole 2. More than one inlet port 12 is provided, so that the sound emitted by the speaker can better enter the amplification cavity 11. In this embodiment, more than two inlet ports 12 are provided, and the more than two inlet ports are evenly spaced on the circumference of the speaker mounting hole 2, and the speaker main body 1 is of an annular structure.

[0026] The inlet port 12 is communicated with the speaker; an outlet port 13 penetrating through to the outside of the speaker main body 1 is provided on the inner wall of the amplification cavity 11 close to the outer side wall of the speaker main body 1. More than two outlet ports 13 are provided and are circularly arranged along the outer side wall of the speaker main body 1. The sound emitted by the speaker enters the amplification cavity 11 through the inlet port 12, and after being mixed in the amplification cavity 11, it is transmitted to the outside of the speaker main body through the outlet port 13.

[0027] In this embodiment, the outlet port 13 is located in the middle of the outer side wall at the upper end of the speaker main body 1; the inlet port 12 is provided at the bottom of the inner side wall of the amplification cavity 11 close to the speaker mounting hole.

[0028] As Figure 3 shown, the upper end of the outer side wall of the speaker main body 1 is arc-shaped upward and inward. Through the arc-shaped outer side wall, the outlet port 13 has a certain angle, so that the range of the sound emitted through the outlet port is larger.

[0029] As Figure 3 shown, the side wall of the speaker mounting hole 2 is arc-shaped upward and outward. On the one hand, it is convenient to install the speaker, and on the other hand, the sound entering the amplification cavity 11 can be mixed through the multiple reflection effects of the amplification cavity 11 and then emitted, improving the sound amplification effect.

[0030] Advantages of the present utility model: By providing more than one sound outlet 13 arranged in a circular array along the outer wall of the speaker main body 1, the sound outlets 13 are located in the 360-degree direction of the outer wall of the speaker main body 1. When the sound emitted by the speaker passes through the sound outlets 13 and is transmitted out, the sound can be propagated in the 360-degree direction of the speaker main body 1, so that the sound emitted by the speaker can be spread around the speaker, and thus the sound amplification effect of the speaker is good.
