Loudspeaker reflex structure and audio equipment

Abstract

The present disclosure relates to a loudspeaker reflection structure and an audio device. The loudspeaker reflection structure comprises a reflection cone body. At least two reflection convex surfaces are formed by convexing one side of the reflection cone body away from the other side, and a first ridge is formed at the transition connection between two adjacent reflection convex surfaces. Therefore, when the reflection cone body is installed in the audio device, the volume of a front cavity enclosed by the reflection convex surface of the loudspeaker reflection structure and the loudspeaker in the audio device can be reduced, thereby increasing the resonance frequency between the front cavity and the sound outlet mesh on the audio device and reducing the resonance amplitude, so that the difference between the peaks and troughs on the resonance frequency response curve is reduced, thereby avoiding sound distortion and ensuring a better listening experience for the listener.

Description

Technical Field

[0001] The present disclosure relates to the technical field of loudspeaker reflection structures, and in particular to a loudspeaker reflection structure and an audio device. Background Art

[0002] The speaker is the core component of the audio device. It is an electroacoustic transducer that converts the changing electrical signal into an acoustic signal and sends it to the human ear, so that the sound can be heard by the human ear. At present, the speaker of the audio device can only radiate in one direction. Therefore, in order to improve the listener's experience of listening to the sound, the speaker of the audio device can be set to directly face the listener.

[0003] However, there is no suitable position to place the speaker on the side of the existing audio device facing the listener, so the speaker cannot emit sound directly toward the listener, and the only option is to emit sound from the side, which makes the sound image backward and the sound quality poor. Therefore, in order to improve the problem of poor sound quality caused by side sound, a speaker reflection structure can be set to make the sound emitted by the speaker diffuse to both sides of the audio device, thereby ensuring the consistency of the sound output on both sides.

[0004] However, the speaker reflection structure in the audio device and the front cavity formed between the speakers and the sound outlet mesh on the side of the audio device will resonate, resulting in peaks and troughs on the frequency response curve of the audio device, causing sound distortion and affecting the listener's listening experience.

DETAILED DESCRIPTION

[0030] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0032] Embodiment 1

[0033] Reference Figures 1 to 4 As shown, the present embodiment provides a loudspeaker reflection structure, comprising a reflection cone body 1, one side of the reflection cone body 1 protrudes toward the other side away from the reflection cone body 1, so that at least two reflection protruding surfaces 2 are formed on the surface of one side of the reflection cone body 1, and a first ridge 32 is formed at the transition connection between two adjacent reflection protruding surfaces 2, so that when the reflection cone body 1 is installed in an audio device, the volume of a front cavity enclosed by the reflection protruding surface 2 of the loudspeaker reflection structure and the loudspeaker in the audio device can be reduced, thereby increasing the resonance frequency between the front cavity and the sound outlet mesh on the audio device, and reducing the resonance amplitude, so that the difference between the peaks and troughs on the resonance frequency response curve is reduced, so as to avoid sound distortion and ensure a better listening experience for the listener.

[0034] When implementing it, refer to Figure 1 In the direction of the drawing shown, the upper surface of the reflective cone body 1 protrudes toward the lower surface away from the reflective cone body 1, that is, the upper surface of the reflective cone body 1 protrudes upward to form at least two reflective protruding surfaces 2. During specific assembly, the reflective cone body 1 is installed at the bottom of the speaker of the audio device, so that the upper surface of the reflective cone body 1 and the speaker form a front cavity, and the sound emitted by the speaker is diffused by the reflective protruding surface 2 on the upper surface of the reflective cone body 1 and then transmitted.

[0035] It should be noted that the speaker reflection structure adjusts the acoustic cavity volume and acoustic mass to adjust the resonant frequency by utilizing the resonance of the acoustic cavity and acoustic mass. Specifically, the acoustic cavity volume is proportional to the acoustic capacity, and the acoustic capacity is inversely proportional to the resonant frequency. Therefore, the acoustic volume is inversely proportional to the resonant frequency. For details, refer to the following formula:

[0036]

[0037]

[0038]

[0039] Among them, F p is the resonance frequency; l is the mesh length; a is the mesh radius; V is the volume of the front cavity of the reflection cone; M a C is the sound quality; a is the sound capacity; c0 is the speed of sound; ρ0 is the medium density.

[0040] In view of this, by reducing the volume of the acoustic cavity, a higher resonance frequency can be obtained. The higher the resonance frequency, the smaller the resonance amplitude, and the smaller the difference in amplitude between the peak and the trough on the frequency response curve.

[0041] Therefore, in this embodiment, at least two reflective protrusions 2 are formed on one side surface of the reflective cone body 1, which can reduce the volume of the front cavity enclosed by the reflective protrusion 2 of the speaker reflection structure and the speaker in the audio device, thereby increasing the resonance frequency and reducing the resonance amplitude, so that the difference between the peaks and troughs on the resonance frequency response curve is reduced, thereby avoiding sound distortion and ensuring a better listening experience for the listener.

[0042] Furthermore, it can be combined with Figure 8 As shown, Figure 8 The resonant frequency response curve formed by the reflective cone body 1 of this embodiment is shown (refer to Figure 8 The solid line curve in the figure) and the resonance frequency response curve formed by the reflection cone body in the prior art (refer to Figure 8 The dotted curve in the figure shows the comparison of Figure 8 It can be seen that the difference between the peak and the trough of the resonant frequency response curve of the reflective cone body 1 of this embodiment is smaller than the difference between the peak and the trough of the resonant frequency response curve formed by the reflective cone body in the prior art. Therefore, in this embodiment, the structural design of the reflective cone body 1 can reduce the difference between the peak and the trough of the resonant frequency response curve, thereby improving the sound quality and providing a better listening experience for the listener.

[0043] When implementing it, refer to Figure 1 and Figure 2As shown, the reflective convex surface 2 includes a first reflective convex surface 21 formed in the middle area of ​​the reflective cone body 1 and a plurality of second reflective convex surfaces 22 arranged on the outer edge of the first reflective convex surface 21 , and the plurality of second reflective convex surfaces 22 are arranged in sequence along the outer periphery of the first reflective convex surface 21 .

[0044] In this embodiment, the first protruding reflective surface 21 can be set to be symmetrical with respect to the symmetry plane of the reflective cone body 1, that is, the reflective cone body 1 itself has a symmetrical structure, that is, the first protruding reflective surface 21 is axially symmetrical, and the symmetry axis coincides with the symmetry plane of the reflective cone body, thereby optimizing the structure or strength of the entire reflective cone body 1.

[0045] Specifically, the first reflective convex surface 21 may be substantially flat or may be a smooth curved surface. The second reflective convex surface 22 may be a smooth curved surface. For example, when four second reflective convex surfaces 22 are provided, two second reflective convex surfaces 22 that are oppositely provided may be concave toward the other side away from the reflective cone body 1, and the other two second reflective convex surfaces 22 that are oppositely provided may be convex toward the other side away from the reflective cone body 1.

[0046] In a specific implementation, a second ridge tip 31 is formed on the first reflective convex surface 21. The second ridge tip 31 may be located at the symmetry axis of the first reflective convex surface 21 (refer to Figure 2 The y-axis shown in FIG. 1 ), that is, the second ridge tip 31 coincides with the symmetry axis of the first reflective convex surface 21; or the second ridge tip 31 may be arranged to intersect the symmetry axis of the first reflective convex surface 21 or to be arranged in parallel with each other.

[0047] Exemplarily, in the axial direction along the symmetry axis of the reflective cone body 1 or the first reflective convex surface 21, the extension length of the second ridge tip 31 may be the maximum value of the dimension of the first reflective convex surface 21 in the direction of the symmetry axis. Alternatively, in other implementations, the extension length of the second ridge tip 31 may be less than the maximum value of the dimension of the first reflective convex surface 21 in the direction of the symmetry axis, and the specific extension length and extension direction of the second ridge tip 31 may be specifically set according to actual needs.

[0048] In this embodiment, in addition to the second ridge 31 provided on the first reflective convex surface 21, a first ridge 32 may be formed at the transitional connection between two adjacent second reflective convex surfaces 22. The second ridge 31 and the first ridge 32 may be provided at the same time, or one of them may be provided alternatively.

[0049] In a specific implementation, one end of the first ridge tip 32 extends to the outer edge of the reflective cone body 1, and the other end of the first ridge tip 32 extends to the outer edge of the first reflective convex surface 21, that is, in the direction from the outer edge of the second reflective convex surface 22 to the outer edge of the first reflective convex surface 21, the extension length of the first ridge tip 32 is the extension length of the second reflective convex surface 22. Alternatively, in other implementations, in the direction from the outer edge of the second reflective convex surface 22 to the outer edge of the first reflective convex surface 21, the extension length of the first ridge tip 32 is less than the extension length of the second reflective convex surface 22.

[0050] In this embodiment, refer to Figure 2 As shown, the first reflective convex surface 21 is symmetrically arranged with respect to the symmetric plane of the reflective cone body 1. Alternatively, the two second reflective convex surfaces 22 and the two first ridge tips 32 located on both sides of the symmetric plane and arranged opposite to each other are both symmetrically arranged with respect to the symmetric plane. Alternatively, the first reflective convex surface 21 is symmetrically arranged with respect to the symmetric plane of the reflective cone body 1, and the two second reflective convex surfaces 22 and the two first ridge tips 32 located on both sides of the symmetric plane and arranged opposite to each other are both symmetrically arranged with respect to the symmetric plane. Through the above three arrangements, the structure or strength of the entire reflective cone body 1 can be optimized.

[0051] Reference Figure 2 As shown, the second reflective convex surface 22 includes four, and the extension lines of the first ridge 32 formed at the transition connection of two adjacent second reflective convex surfaces 22 do not overlap. That is to say, the second reflective convex surface 22 includes a first sub-reflective convex surface 221, a second sub-reflective convex surface 222, a third sub-reflective convex surface 223, and a fourth sub-reflective convex surface 224 arranged at intervals along the circumference of the first reflective convex surface 21; the first sub-ridge 321 is formed at the transition connection between the first sub-reflective convex surface 221 and the second sub-reflective convex surface 222, the second sub-ridge 322 is formed at the transition connection between the second sub-reflective convex surface 222 and the third sub-reflective convex surface 223, the third sub-ridge 323 is formed at the transition connection between the third sub-reflective convex surface 223 and the fourth sub-reflective convex surface 224, and the fourth sub-ridge 324 is formed at the transition connection between the fourth sub-reflective convex surface 224 and the first sub-reflective convex surface 221.

[0052] In specific implementation, the first sub-ridge tip 321 and the fourth sub-ridge tip 324, and the second sub-ridge tip 322 and the third sub-ridge tip 324 can be symmetrically arranged relative to the symmetry axis of the reflective cone body 1. In addition, the extension lines of the first sub-ridge tip 321 and the third sub-ridge tip 323 can be arranged not to overlap, that is, the extension lines of the first sub-ridge tip 321 and the third sub-ridge tip 323 intersect and form a certain angle. Similarly, the extension lines of the second sub-ridge tip 322 and the fourth sub-ridge tip 324 can be arranged not to overlap, that is, the extension lines of the second sub-ridge tip 322 and the fourth sub-ridge tip 324 intersect and form a certain angle. The specific value of the angle can be set according to actual needs to meet the structural strength of the reflective cone body.

That is, the sound outlet surface of the speaker 4 faces the reflective convex surface 2 of the reflective cone body 1, so that the sound emitted by the speaker 4 is diffused through the reflective convex surface 2 and then transmitted through the sound outlet mesh holes 53 on the first shell 51 and the second shell 52. In addition, the sound outlet mesh holes 53 are arranged at the positions corresponding to the front cavity 54 on the first shell 51 and the second shell 52, which can shorten the propagation path of the sound and reduce the loss of sound quality transmission.
