Description

Technical Field

[0001] The present invention relates to the technical field of audio playing equipment, and in particular to a sound box. Background Art

[0002] The conventional structure of some sound reinforcement speakers on the market now is that the high frequency and low frequency are on the same sounding surface. After the frequency division process, the high frequency and low frequency are combined together and propagated through direct sound. Since the superposition of the crossover parts of the high frequency and low frequency bands will cause the timbre of the human voice to be poor, in order to increase the sound pressure of the speaker, multiple speakers are usually installed on one speaker to achieve this. After installing multiple speakers, the sound waves of the speaker become cylindrical sound waves, resulting in strong directivity of the speaker, too small radiation angle, and uneven sound coverage in the space. Although the uneven sound coverage in the space can be improved by increasing the number of sound reinforcement speakers evenly distributed in the room, the sound image will shift after too many speakers, and ultimately multiple speakers are required to achieve sound reinforcement in the room, which increases the cost and reduces the sound effect. Summary of the invention

[0039] See also Figures 1 to 8 An embodiment of the present invention provides a speaker, which includes a speaker shell 100, a high-frequency speaker 200 and at least one low-frequency speaker 300. The high-frequency speaker 200 is arranged in the speaker shell 100; the low-frequency speaker 300 is also arranged in the speaker shell 100, and the low-frequency speaker 300 is arranged beside the high-frequency speaker 200; wherein the sound outlet surfaces of the high-frequency speaker 200 and the low-frequency speaker 300 are oriented in the same direction, and the sounds in the high-frequency speaker 200 and each low-frequency speaker 300 are output from their respective sound outlet surfaces and then exported from different sides of the speaker shell 100.

[0040] The technical solution provides a speaker, which forms a point sound source to increase the radiation area of ​​the speaker by arranging a plurality of low-frequency speakers 300 around the high-frequency speaker 200, and the sound outlet surfaces of the high-frequency speaker 200 and the low-frequency speaker 300 are in the same direction. By exporting the sound in the high-frequency speaker 200 and the low-frequency speaker 300 from different sides of the speaker shell 100, it is possible to avoid mixing high-frequency sound and low-frequency sound, which is conducive to improving the sound effect. . Through the above arrangement, the sound after frequency division enters the high-frequency speaker 200 and the low-frequency speaker 300 respectively, so that the sound of different frequencies is emitted from the sound outlet surfaces of the high-frequency speaker 200 and the low-frequency speaker 300 respectively, so that the low-frequency sound and the high-frequency sound are emitted together, forming a point sound source to increase the coverage angle of the sound, and effectively improving the problem of small sound coverage space of the speaker in the prior art. The sound emitted from the high-frequency speaker 200 and the low-frequency speaker 300 is exported from different sides of the speaker shell 100, and at the same time, the high-frequency sound and the low-frequency sound can be propagated separately to avoid mixing, thereby improving the sound effect of the speaker.

[0041] For example, Figure 8 As shown, in the present application, the sound outlet surface 320 of the low frequency speaker and the sound outlet surface 210 of the high frequency speaker are both oriented toward Figure 8 The left direction in the figure; while the high-frequency sound is derived from the direction X1 in Figure 8 The left direction in the figure, the export direction of low-frequency sound X2 is Figure 8 It should be noted that Figure 8 The orientation of the sound emitting surface of the speaker of different frequencies and the direction of the sound output of different frequencies are merely examples, and other sides may also be used in other embodiments.

[0042] It should be noted that the sound entering the high-frequency speaker 200 is transmitted from the sound outlet surface 210 of the high-frequency speaker; and the sound entering the low-frequency speaker 300 is transmitted from the sound outlet surface 320 of the low-frequency speaker. The sound outlet surfaces of the high-frequency speaker and the low-frequency speaker are both provided with pores to facilitate sound transmission. In the high-frequency speaker 200 and the low-frequency speaker 300, the side adjacent to the sound outlet surface is a sealed side, which is arranged to prevent sound from leaking from the side adjacent to the sound outlet surface.

[0043] It is understandable that there is no restriction on the specific structure of the speaker shell 100, and it can be designed according to the specific needs of the user. The number of low-frequency speakers 300 can be one, two, three, four, etc. As a preferred solution, multiple low-frequency speakers 300 can be arranged around the high-frequency speaker 200 with the high-frequency speaker 200 as the center to form a point sound source, which has the advantage of a large coverage angle. The sound output surfaces of the high-frequency speaker 200 and the low-frequency speaker 300 are facing the same direction, which means that the sound output surfaces of the high-frequency speaker 200 and the low-frequency speaker 300 are facing the same side of the speaker shell 100 at the same time. The sound of the high-frequency speaker 200 and the low-frequency speaker 300 is derived from different sides of the speaker shell 100, which can be achieved by setting the structure of the speaker shell 100. For example, a cavity for accommodating the high-frequency speaker 200 and the low-frequency speaker 300 can be set in the speaker shell 100, and a through hole, a through groove or a gap connected to the sound outlet surface of the high-frequency speaker 200 and the low-frequency speaker 300 can be set on the speaker shell 100, so that the through hole, through groove or gap connected to the sound outlet surface 210 of the high-frequency speaker forms a high-frequency sound guide channel; the through hole or gap connected to the sound outlet surface 320 of the low-frequency speaker forms a low-frequency sound guide channel, and the outlet of the high-frequency sound guide channel and the outlet of the low-frequency sound guide channel are located on different sides of the speaker shell 100. Exemplarily, the outlet of the high-frequency sound guide channel can be located on the top surface of the speaker shell, and the outlet of the low-frequency sound guide channel can be located on any side adjacent to the top surface of the speaker shell, or on the bottom surface.

[0044] Combination Figure 2 , Figure 4 and Figure 8 It is understood that in one embodiment, if Figure 4 As shown, a sound outlet 124 is constructed on the speaker shell 100, and the sound outlet surface of the high-frequency speaker 200 corresponds to the sound outlet 124 and is exposed outside the speaker shell from the sound outlet 124; the speaker shell 100 is also constructed with a sound guide channel connected to the sound outlet surface of the low-frequency speaker 300, and the outlet of the sound guide channel is arranged on at least one side of the speaker shell 100 except the side where the sound outlet 124 is located, and the sound of the low-frequency speaker 300 is exported from the sound guide channel.

[0045] Among them, by setting a sound outlet 124 on the speaker shell 100, and making the sound outlet surface of the high-frequency speaker 200 correspond to the sound outlet 124, so that the sound outlet surface of the high-frequency speaker 200 is exposed outside the speaker shell 100 from the sound outlet 124, so that the sound in the high-frequency speaker 200 is directly transmitted from the sound outlet surface of the high-frequency speaker 200. In this way, there is no need to set a sound guide channel for the export of high-frequency sound on the speaker shell. By constructing a sound guide channel on the speaker shell 100, and by setting the outlet of the guide channel on at least one side other than the side where the sound outlet 124 is located, the sound coming out of the sound outlet surface of the low-frequency speaker 300 is exported through the outlet of the sound guide channel, so that the sound of the low-frequency speaker 300 and the sound of the high-frequency speaker 200 are exported from different sides of the speaker shell 100.

[0046] For example, Figure 8 As shown, the high-frequency sound in the high-frequency speaker 200 can be emitted from the left side of the speaker shell; the outlet of the sound guide channel 130 connected to the sound outlet surface of the low-frequency speaker 300 can be set on the upper and lower sides of the speaker shell 100. Of course, in other embodiments, the high-frequency sound in the high-frequency speaker 200 can also be emitted from the top surface of the speaker shell, and the outlet of the sound guide channel 130 connected to the sound outlet surface of the low-frequency speaker 300 can be set on the front, rear, left, and right sides of the speaker shell 100.

[0047] Since the low-mid frequency sound from the low-frequency speaker 300 and the high-frequency sound from the high-frequency speaker 200 are guided out from different sides of the speaker housing 100, the bass and treble are propagated from different directions. Since the two different frequency sounds are guided out in different directions, the superposition of the two different frequency sounds can be avoided, thereby avoiding the poor timbre, so that the speaker not only has the advantage of a large radiation angle, but also has the advantage of improved sound quality.

[0048] It is understandable that the specific formation method of the sound outlet 124 and the sound guide channel is not limited. Figure 1 , Figure 2 and Figure 8As shown, in one embodiment of the present application, the speaker shell 100 includes a box body 110 and a panel 120, the box body 110 is constructed with a first cavity 111 with an opening at one end and a plurality of second cavities 112 with an opening at one end, the second cavity 112 is arranged on the side of the first cavity 111, and each opening is arranged on the same side of the box body 110, the high-frequency speaker 200 is arranged in the first cavity 111, and the low-frequency speaker 300 is arranged in the second cavity 112; the sound outlet 124 is opened on the panel 120, and the sound outlet 124 passes through the panel 120 along the thickness direction of the panel 120, the panel 120 is covered on the side of the box body 110 with an opening, and there is a gap between the side of the panel 120 facing the opening and the side of the box body 110, so that a sound guide channel 130 is defined between the panel 120 and the box body 110.

[0049] A first cavity 111 is provided on the box 110 to accommodate and install the high-frequency speaker 200, and an opening is provided on the first cavity 111 to facilitate placing the high-frequency speaker 200 in the first cavity 111; similarly, a second cavity 112 is provided on the box 110 to accommodate and install the low-frequency speaker 300. It should be noted that when the high-frequency speaker 200 and the low-frequency speaker 300 are installed, the sound outlet surfaces are exposed from the openings of the cavities. Therefore, by providing the openings of the first cavity 111 and the second cavity 112 on the same side of the box 110, the sound outlet surfaces of the high-frequency speaker 200 and the low-frequency speaker 300 can be oriented in the same direction.

[0050] The panel 120 is covered on the side of the box 110 with an opening, and a gap is set between the panel 120 and the box 110, so that a sound guide channel 130 is defined between the panel 120 and the box 110. The sound outlet 124 is set on the panel 120 and penetrates the panel 120 along the thickness direction of the panel 120, so that the sound of the high-frequency speaker 200 is exported along the thickness direction of the panel 120. The sound of the low-frequency speaker 300 is exported from the gap between the box 110 and the panel 120, and the outlet direction of the gap is perpendicular to the thickness direction of the panel 120, that is, the export direction of the sound of the low-frequency speaker 300 is perpendicular to the thickness direction of the panel 120. By setting as above, the low-frequency speaker 300 is located behind the panel 120. In this way, when the low-frequency speaker 300 and the high-frequency speaker 200 sound at the same time, the panel 120 can attenuate the sound of part of the high-frequency sound on this side of the low-frequency speaker 300, thereby effectively avoiding the mixing of the low-frequency sound and the high-frequency sound to cause the difference in phase and timbre, thereby improving the timbre. This technical solution cleverly utilizes the panel 120 and the box body 110, as well as the opening direction of the sound outlet 124 on the panel 120 to make the sound of the low-frequency speaker 300 and the high-frequency speaker 200 be respectively derived from different directions of the speaker shell 100. Through a simple structure, it can be achieved that while ensuring a larger sound radiation angle, the high and low frequencies can be propagated separately, thereby improving the sound quality of the speaker.

[0051] like Figure 4 and Figure 8 As shown, in one embodiment, the side of the speaker shell 100 on which the sound outlet 124 is provided is recessed toward the side of the speaker shell 100 opposite to the side on which the sound outlet 120 is provided, so as to define a guide cavity, and the sound outlet is provided on the cavity wall of the sound guide cavity and is connected with the sound guide cavity; the cavity diameter of the sound guide cavity 125 gradually increases from the end where the sound outlet 124 is located to the end away from the sound outlet 124. Specifically, the sound outlet 124 is provided at the middle position of the panel 120, and the middle position of the panel 120 is recessed as a whole toward the direction close to the box body 110, so that a recessed space is formed on the side of the panel 120 away from the box body 110, and the sound outlet 124 is just provided at the lowest position of the recessed space, and is also located in the middle position. By gradually increasing the diameter of the sound guide cavity 125 from one end of the sound outlet 124 to the end away from the sound outlet, the high-pitched sound coming out of the sound guide cavity 125 can be diffused through the cavity wall of the sound guide cavity 125, which is beneficial to amplify the high-pitched sound.

[0052] The housing of the high frequency speaker 200 is fixedly connected to the panel 120 by bolts, and the sound outlet surface of the high frequency speaker 200 is set to be spherical, and the outer peripheral surface of the spherical sound outlet surface just fits the periphery of the sound outlet 124 on the panel 120. By setting the sound outlet surface to be spherical, the area of ​​the sound outlet surface can be increased, thereby improving the sound extraction performance of the high frequency speaker 200.

[0053] Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, in one embodiment, a sound guide cone 121 is provided in the sound guide channel, and the sound guide cone 121 is constructed to gradually protrude from the surroundings to the middle position toward the direction of the low-frequency speaker 300. Specifically, a structure protruding toward the direction of the speaker is provided on the side of the panel 120 facing the speaker, and the sound guide channel is essentially formed by the gap between the panel 120 and the box body 110. Therefore, the above sound guide cone 121 is provided on the side of the panel 120 facing the speaker to increase the radiation area in the sound guide channel, so that the sound coming out of the low-frequency speaker 300 is diffused by the sound guide cone 121 and then output through the outlet of the sound guide channel 130. Furthermore, the sound guide cone 121 is constructed as an arc surface, so that the attenuation of the sound can be reduced in the process of diffusing the mid-bass, which is beneficial to ensure the volume of the sound output.

[0054] Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, in one embodiment, a plurality of spaced sound guide ribs 122 are also constructed on the side of the sound guide channel facing the low-frequency speaker 300 at the exit of the sound guide channel, and a first sound guide groove 123 is defined between each two adjacent sound guide ribs 122 and the wall of the sound guide channel, and the first sound guide groove 123 is connected to the sound guide channel. By providing the sound guide ribs 122 at the exit of the sound guide channel 130, and guiding the sound in the low-frequency speaker 300 through the sound guide groove formed between the sound guide ribs 122, the sound amplification effect for the mid-bass is improved. In this embodiment, a circle of spaced sound guide ribs 122 is provided on the periphery of the side of the panel 120 facing the box body 110, and a first sound guide groove 123 is defined between each two adjacent sound guide ribs 122 and the panel 120.

[0055] Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 In one embodiment, the width of the two ends of the sound guide rib 122 along its own extension direction is set to gradually decrease in the direction away from each other. Such a setting can effectively reduce the loss of sound caused by the two ends of the sound guide rib 122 being too sharp, thereby improving the quality of sound output.

[0056] Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8In one embodiment shown, the extension direction of the sound guide ribs 122 corresponding to the four corners of the low-frequency speaker 300 is inclined to the side of the speaker shell 100. In this way, the extension direction of the first guide groove surrounded by the sound guide ribs 122 and the panel 120 corresponds to the low-frequency speaker 300, which is conducive to guiding the mid-bass. Specifically, in this embodiment, the extension direction of the sound guide ribs 122 arranged at intervals along the width direction of the panel 120 is perpendicular to the edge of the width direction of the panel 120, and the extension direction of the first sound guide groove 123 formed in this way is also perpendicular to the edge of the width direction of the panel 120, and the sound guide ribs 122 of the portion of the width direction of the panel 120 corresponding to the corner of the low-frequency speaker 300 are perpendicular to the edge of the width square of the panel. Similarly, the extension direction of the sound guide ribs 122 arranged at intervals along the length direction of the panel 120 is perpendicular to the long side of the panel 120; the sound guide ribs 122 of the portion of the length direction of the panel corresponding to the corner of the low-frequency speaker 300 are perpendicular to the edge of the length direction of the panel 120. Such a configuration forms radially arranged first sound guide grooves 123 around the low-frequency speaker 300, thereby facilitating the propagation and diffusion of sound.

[0057] like Figure 2 As shown, in one embodiment, the periphery of the sound outlet surface of each low-frequency speaker 300 is configured with a second sound guide groove 310 arranged around the periphery of the sound outlet surface. By configuring the second sound guide groove 310 around the periphery of the sound outlet surface of the low-frequency speaker 300, the diffusion performance of the sound of the low-frequency speaker 300 is improved. Specifically, the second sound guide groove 310 is configured as a U-shaped groove.

[0058] like Figure 1 , Figure 2 and Figure 8 As shown, in one embodiment, there are two low-frequency speakers 300, and the two low-frequency speakers 300 are symmetrically arranged on both sides of the high-frequency speaker 200. The two low-frequency speakers 300 are symmetrically arranged on both sides of the high-frequency speaker 200, so that the overall structure of the speaker is more balanced, and the distribution of the low-frequency speakers 300 is more even, thereby improving the radiation of the sound and improving the bass sound quality of the speaker.

[0059] In the present application, the low-frequency speaker 300 is fixedly connected to the box body 110 by bolts. The high-frequency speaker 200 and the low-frequency speaker 300 are installed separately, and the sound outlet surface 210 of the high-frequency speaker is installed on the front of the panel 120, and the sound outlet surface 320 of the low-frequency speaker is installed on the back of the panel 120. The medium and low frequency sounds are guided out from the side of the panel 120 through the sound guide cone 121 on the panel 120; the high-frequency speaker 200 is installed in the middle of the panel 120, and the front is made into a neat appearance surface, and the back is specially designed with a sound guide cone 121 and a circle of specially designed sound guide ribs 122 according to the installation position of the low-frequency speaker 300 and the performance requirements of the bass. The medium and low sounds are diffused by the sound guide cone 121 and then emitted through the first sound guide groove 123 formed by the sound guide ribs 122 on the side, and sound together with the high-frequency sound on the front to complete the sound propagation. Since the bass and treble are emitted from a point to form a point sound source, the radiation area of ​​the speaker is increased; and the low-frequency speaker 300 installed behind the panel 120 can attenuate part of the high-frequency sound when making sound, avoiding mixing with the treble sound to cause phase difference and timbre difference, thereby improving the sound quality of the speaker.

[0060] Specifically, the speaker assembly process is as follows:

[0061] First, install the high-frequency speaker on the panel 120 and fix it with screws; then install the terminal block 400 into the box 110, and then install the low-frequency speaker 300 into the box 110 and connect the wires, and fix it with screws; then connect the panel 120 with the high-frequency speaker 200 to the wires of the high-frequency speaker 200 and assemble it to the box 110 with the low-frequency speaker 300, and fix it with glue or other means to complete the assembly of the speaker.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
