Description

Technical Field

[0001] This utility model relates to the field of audio, specifically to a rear-mounted stereo speaker. Background Technology

[0002] As an audio playback device, a speaker typically consists of loudspeakers, power amplifiers, audio processing equipment, and preamplifiers. To better propagate sound, the loudspeakers and sound-emitting parts of a speaker are generally positioned at the front, allowing sound waves to diffuse forward and facilitating the reception of the sound waves for the listener to appreciate their beauty. If the sound-emitting part is placed at the back, there is no sound emanating from the front, and the sound waves diffuse backward, resulting in a less focused sound. This leads to reduced sound loss, lower volume, and a lack of emphasis on the mid, high, and low frequencies. Furthermore, this arrangement also presents the following problems: the stereo effect is relatively poor, especially in the mid and high frequencies, where the overall effect is often unsatisfactory. Utility Model Content

[0003] The purpose of this invention is to provide a rear-mounted stereo speaker to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rear-mounted stereo speaker, comprising:

[0005] The main body of the speaker has a rear-facing speaker fixedly installed inside;

[0006] The sound-emitting baffle is installed on the rear side of the speaker body, with a gap between it and the rear side of the speaker body, for reflecting sound waves forward.

[0007] Furthermore, multiple reinforcing ribs are fixedly installed on the edge of the sound-generating baffle.

[0008] Furthermore, a sound-guiding sphere matching the loudspeaker is fixedly installed on the sound-generating baffle, and the sound-guiding sphere faces the loudspeaker.

[0009] Furthermore, a sound insulation plate is fixedly installed in the middle of the sound-emitting baffle to separate the two speakers.

[0010] Furthermore, the soundproofing panel is located between the two speakers.

[0011] Furthermore, the edges of both the reinforcing bone and the sound insulation board are rounded.

[0012] Furthermore, the distance between the sound-guiding sphere and the speaker is 2mm-5mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention places the speaker on the rear side of the speaker body and uses a sound-emitting baffle to reflect the sound. After the sound is reflected back and forth between the sound-emitting baffle and the rear side of the speaker body, it is emitted outward from the gap, forming a three-dimensional sound-emitting part, which makes the sound of the speaker more three-dimensional, especially the mid and high frequencies are more prominent.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 As shown, this embodiment discloses a rear-mounted stereo speaker, including a speaker body 1. Two rearward-facing speakers 7 are fixedly installed inside the speaker body 1. The speaker body 1 has a circuit board, power amplifier, audio processing equipment, preamplifier and other structures inside, which are the same as existing speakers and are prior art, so they will not be described in detail here.

[0022] The sound-emitting baffle 2 is fixedly installed on the rear side of the speaker body 1 using bolts. The sound-emitting baffle 2 extends downward and is rounded, as shown. Figure 3 and Figure 4The concave portion forming an arc, as shown, is more conducive to sound diffusion. In principle, the more concave portions there are, the better the sound waves will be emitted forward. A gap 4 is left between the sound-emitting baffle 2 and the rear side of the speaker body 1. The size of the gap 4 is set according to the volume of the speaker. The sound waves emitted by the speaker 7 are reflected and refracted by the sound-emitting baffle 2, and the sound waves will diffuse forward, radiating outward from the gap 4 and propagating the sound forward. The stereo effect of the sound is better, especially the mid and high frequencies are more prominent, and the sound is stronger.

[0023] In this application, such as Figure 3 As shown, multiple evenly distributed reinforcing ribs 5 are fixedly installed at the upper and lower edges of the sound-generating baffle 2, and the reinforcing ribs 5 are arranged perpendicularly to the edges of the sound-generating baffle 2. Sound holes are formed between adjacent reinforcing ribs 5, which can better diffuse sound waves outward.

[0024] A sound insulation plate 6 is fixedly installed at the center of the sound-emitting baffle 2. The sound insulation plate 6 divides the sound-emitting baffle 2 into two parts and is located in the middle of the two speakers 7, separating the two speakers 7. When the two speakers 7 are working, the sound waves will be reflected back after touching the sound insulation plate 6, thus ensuring that the sound waves of the two speakers 7 will not mix together, making the stereo effect of the left and right speakers 7 stronger. At the same time, it can also avoid the situation where the sound waves are mixed up before they are emitted.

[0025] A sound-guiding sphere 3, directly opposite the speaker 7, is also fixedly installed on the sound-emitting baffle 2. Figure 3 As shown, the sound-guiding sphere 3 faces the sound-emitting part of the speaker 7. The sound-guiding sphere 3 has a smooth spherical structure. The optimal distance between the sphere and the speaker is 2-5mm, which makes it easier to project the sound waves forward 360 degrees, resulting in better sound.

[0026] In this embodiment, the edges of the sound insulation panel 6 and the reinforcing rib 5 are rounded. When sound waves propagate to sharp edges, irregular reflections and scattering can easily occur, leading to chaotic sound and acoustic problems such as echoes and buzzing. Rounded edges make the reflection of sound waves at the edges smoother and more regular, reducing unnecessary reflections and scattering, thereby improving the clarity and purity of the sound. Rounded edges can more naturally guide sound waves to diffuse in all directions, avoiding situations where sound is too concentrated in some areas or insufficient in others, thus achieving more uniform sound coverage.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
