DETAILED DESCRIPTION

[0045] In order to make the person skilled in the art better understand the utility model scheme, the utility model is further explained in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the protection scope of the utility model.

[0046] Please refer to Figures 1 to 7 The utility model embodiment provides a sound column loudspeaker, which comprises a housing 1, wherein a plurality of full-frequency units and at least one high-frequency unit 3 are arranged on the housing 1.

[0047] Among them, the sound emitting normal of at least one high-frequency unit 3 and the sound emitting normal of at least one full-frequency unit are arranged in different directions.

[0048] It should be noted that the existing sound column loudspeaker generally has a plurality of full-frequency loudspeakers arranged on the housing, although the full-frequency loudspeaker has good playing effect, there are certain defects under such design, specifically as Figure 6 As shown in the figure, from Figure 6 It can be seen that in the 1kHz to 10kHz section, the frequency response curve of the five full-frequency loudspeakers appears a large missing valley, the loudness is 85.3dB at 2992.5Hz, and the attenuation is 66.0dB at 8009.2Hz, so when the sound column loudspeaker adopts all full-frequency units, the high-frequency sound waves will be interfered and cancelled, thereby causing the high frequency of the full-frequency loudspeaker to be poor, and the full-frequency effect cannot be reflected, and the external sound lacks gradation. In order to overcome the above problems, in the sound column loudspeaker of the embodiment, a plurality of full-frequency units and at least one high-frequency unit 3 are arranged on the housing 1, specifically as Figure 7 As shown in the figure, from Figure 7It can be seen that in the 5kHz-10kHz segment, the frequency response curve of the sound column loudspeaker is relatively flat, and the loudness is maintained at a relatively high level. Therefore, the high-frequency unit 3 can compensate for the loss of loudness in the high-frequency segment of the full-frequency unit, effectively improve the full-frequency effect, make the outdoor sound have stronger level, and by setting the sound emission normal line of the high-frequency unit 3 and the sound emission normal line of the full-frequency unit in different directions, the sound propagation in a larger direction range can be realized, the sound diffusion is stronger, that is, a larger sound field is generated, so that the sound column loudspeaker has better sound quality effect, and the user can obtain better experience.

[0049] In addition, it should be noted that the sound emission normal line mentioned in the embodiment refers to a ray with the center of the loudspeaker diaphragm pointing outward, which is also called the sound emission normal line.

[0050] Further, in one of the specific embodiments in the embodiment, as shown in Figure 3 the number of full-frequency units is designed to be four, specifically, the first full-frequency unit 2a, the second full-frequency unit 2b, the third full-frequency unit 2c, and the fourth full-frequency unit 2d;

[0051] The number of high-frequency units 3 is designed to be one.

[0052] The first full-frequency unit 2a, the second full-frequency unit 2b, the high-frequency unit 3, the third full-frequency unit 2c, and the fourth full-frequency unit 2d are sequentially arranged along the first direction of the shell 1.

[0053] Specifically, in the embodiment, the first direction specifically refers to the height direction of the shell 1, and the first full-frequency unit 2a, the second full-frequency unit 2b, the high-frequency unit 3, the third full-frequency unit 2c, and the fourth full-frequency unit 2d are sequentially arranged from top to bottom along the height direction of the shell 1.

[0054] It should be noted that in other specific embodiments, the number of full-frequency units can also be eight, ten, etc., and the number of high-frequency units 3 can be one, two, etc., and the embodiment does not limit this.

[0055] Further, as shown in Figure 3 in the above specific embodiment, the first direction of the shell 1 is designed as the Z-axis, the sound emission normal line of the high-frequency unit 3 is designed as the X-axis, and the horizontal direction perpendicular to the sound emission normal line of the high-frequency unit 3 is designed as the Y-axis;

[0056] Among them, with the high-frequency unit 3 as the dividing point, the high-frequency unit 3 is above the positive direction of the Z-axis, the high-frequency unit 3 is below the negative direction of the Z-axis, the left of the high-frequency unit 3 is the negative direction of the Y-axis, the right of the high-frequency unit 3 is the positive direction of the Y-axis, the front of the high-frequency unit 3 is the positive direction of the X-axis, and the back of the high-frequency unit 3 is the negative direction of the X-axis.

[0057] Among them, the X-axis and Y-axis form the XY plane, and the X-axis and Z-axis form the XZ plane;

[0058] Based on the coordinate system designed above, the orientation of the sound output normal of each unit in this embodiment is as follows:

[0059] The sound output normal of the high-frequency unit 3 is set towards the positive direction of the X-axis;

[0060] like Figure 4 As shown, the sound output normal of the first full-frequency unit 2a is biased towards the negative direction of the Y-axis, and the projection of the sound output normal of the first full-frequency unit 2a and the sound output normal of the high-frequency unit 3 onto the XY plane forms a first angle; wherein, the first angle θ1 satisfies: 6°≤θ1≤16°;

[0061] The sound output normal of the second full-range unit 2b is biased towards the positive direction of the Y-axis, and the projection of the sound output normal of the second full-range unit 2b and the sound output normal of the high-frequency unit 3 onto the XY plane forms a second angle; wherein, the second angle θ2 satisfies: 5°≤θ2≤15°;

[0062] The sound output normal of the third full-frequency unit 2c is biased towards the negative direction of the Y-axis, and the projection of the sound output normal of the third full-frequency unit 2c and the sound output normal of the high-frequency unit 3 onto the XY plane forms a third angle; wherein, the third angle θ3 satisfies: 10°≤θ3≤20°;

[0063] The sound output normal of the fourth full-range unit 2d is biased towards the positive direction of the Y-axis, and the projection of the sound output normal of the fourth full-range unit 2d and the sound output normal of the high-frequency unit 3 onto the XY plane forms a fourth angle; wherein, the fourth angle θ4 satisfies: 11°≤θ4≤21°;

[0064] It should be noted that, simply put, the specific orientations of the first full-range unit 2a, the second full-range unit 2b, the high-frequency unit 3, the third full-range unit 2c, and the fourth full-range unit 2d are left, right, center, left, and right, respectively. With this design, the column speaker can achieve a wide horizontal coverage range of 145° to 180°, effectively creating a wider and broader sound field, so that users can obtain an effective listening effect no matter where they are in front of the column speaker.

[0065] Furthermore, in addition to deflecting in the positive and negative directions of the Y-axis, the first full-range unit 2a to the fourth full-range unit 2d described above can also deflect in the positive and negative directions of the Z-axis, thereby enabling the sound to be reflected by the ceiling and the floor of the room, thus giving the column speaker a stronger sound quality.

[0066] Specifically, as shown in Figure 5 the sound emission normal of the first full-frequency unit 2a is arranged to be deviated to the positive direction of the Z axis, and the projection of the sound emission normal of the first full-frequency unit 2a and the sound emission normal of the second full-frequency unit 2b on the XZ plane forms a fifth included angle; wherein the fifth included angle θ5 satisfies: 5°≤θ5≤15°;

[0067] the sound emission normal of the second full-frequency unit 2b is arranged to be deviated to the positive direction of the Z axis, and the projection of the sound emission normal of the second full-frequency unit 2b and the sound emission normal of the second full-frequency unit 2b on the XZ plane forms a sixth included angle; wherein the sixth included angle θ6 satisfies: 6°≤θ6≤16°;

[0068] the sound emission normal of the third full-frequency unit 2c is arranged to be deviated to the negative direction of the Z axis, and the projection of the sound emission normal of the third full-frequency unit 2c and the sound emission normal of the second full-frequency unit 2b on the XZ plane forms a seventh included angle; wherein the seventh included angle θ7 satisfies: 5.3°≤θ7≤15.3°;

[0069] the sound emission normal of the fourth full-frequency unit 2d is arranged to be deviated to the negative direction of the Z axis, and the projection of the sound emission normal of the fourth full-frequency unit 2d and the sound emission normal of the second full-frequency unit 2b on the XZ plane forms an eighth included angle; wherein the eighth included angle θ8 satisfies: 5°≤θ8≤15°;

[0070] It should be noted that in the above design, the sound emission normal of the first full-frequency unit 2a and the second full-frequency unit are both arranged to be deviated to the positive direction of the Z axis, so that the sound emitted by the first full-frequency unit 2a and the second full-frequency unit 2b can be reflected by the indoor roof to the front of the sound column loudspeaker, and the sound emission normal of the third full-frequency unit 2c and the fourth full-frequency unit 2d are both arranged to be deviated to the negative direction of the Z axis, so that the sound emitted by the third full-frequency unit 2c and the fourth full-frequency unit 2d can be reflected by the indoor floor to the front of the sound column loudspeaker, thereby realizing sound propagation in a larger direction range and stronger sound diffusion, i.e. generating a larger sound field, so that the sound column loudspeaker has better sound quality effect.

[0071] Further, since the distance between the sound column loudspeaker and the indoor roof is much greater than the distance between the sound column loudspeaker and the indoor floor under normal placement of the sound column loudspeaker, it is preferred that the fifth included angle is greater than the first included angle, and the sixth included angle is greater than the second included angle;

[0072] the seventh included angle is smaller than the third included angle, and the eighth included angle is smaller than the fourth included angle.

[0073] It can be simply understood that the angle of upward deflection of the first full-frequency unit 2a is greater than the angle of leftward deflection, and the angle of upward deflection of the second full-frequency unit 2b is greater than the angle of rightward deflection;

[0074] The third full-frequency unit 2c deflects downward at a smaller angle than it deflects to the left, and the fourth full-frequency unit 2d deflects downward at a smaller angle than it deflects to the right.

[0075] Furthermore, such as Figure 5 As shown, in this embodiment, the first full-frequency unit 2a, the second full-frequency unit 2b, the high-frequency unit 3, the third full-frequency unit 2c, and the fourth full-frequency unit 2d are arranged in an arc shape protruding from the outer surface of the housing 1 on the housing 1;

[0076] Furthermore, the projection of the sound output normal of the first full-range unit 2a and the sound output normal of the fourth full-range unit 2d onto the XZ plane forms a ninth angle, and the ninth angle θ9 satisfies: 15°≤θ9≤25°.

[0077] It should be noted that arranging the above-mentioned units in an arc shape can effectively improve the diffusion of the column speaker, making the sound radiation range of the column speaker wider and more uniform, and the column speaker has better sound quality, thus making the column speaker compatible with indoor and outdoor environments.

[0078] Furthermore, such as Figure 2 As shown, in this embodiment, the housing 1 is detachably equipped with a mesh cover 8, which is provided corresponding to the full-frequency unit and the high-frequency unit 3.

[0079] It should be noted that the mesh cover 8 in this embodiment can be assembled by means of snap-fit, screw fixing, etc. In addition, the mesh cover 8 can also be fixed to the shell 1 by means of adhesive, hot melt connection, welding, etc.

[0080] Furthermore, such as Figure 2 As shown, in this embodiment, a light-emitting body 6 is also installed on the housing 1, and a light guide 7 is installed on the light-emitting surface of the light-emitting body 6.

[0081] Specifically, the light source 6 can be a light strip, light bar, etc. The design of the light guide 7 can make the light emitted by the light source 6 more directional, thus improving the lighting effect.

[0082] It should be noted that the above design enables the column speaker to create a lighting atmosphere, providing users with a better experience.

[0083] Furthermore, such as Figure 2 As shown, the housing 1 in this embodiment is also provided with an air duct 5. The air duct 5 adopts a long strip-shaped through hole design to maximize its area, so that the sound resonates in the housing 1, thereby increasing the sound pressure and low frequency volume.

[0084] Please see Figures 1 to 9The utility model discloses an audio amplifier 9, and the audio amplifier 9 includes a shell 902 and the audio column loudspeaker 901, wherein the inside of the shell 902 is provided with a first cavity 903 and a second cavity 905 which are independent of each other, wherein the first cavity 903 is provided with a loudspeaker assembly, and the audio column loudspeaker 901 is installed in the second cavity 905, and the audio column loudspeaker 901 can be driven to extend out of the shell 902 or be stored in the second cavity 905.

[0088] In the audio amplifier 9 in the embodiment, the low-frequency loudspeaker 904 is separately placed in the first cavity 903, and the audio column loudspeaker 901 is arranged in the second cavity 905 in a lifting manner, so that the low-frequency loudspeaker 904 does not interfere with the audio column loudspeaker 901 to affect the sound quality effect when the audio amplifier 9 works.

[0089] In addition, in the audio column loudspeaker 901 in the embodiment, a plurality of full-frequency units and at least one high-frequency unit 3 are arranged on the shell 1, the high-frequency unit 3 can compensate for the high-frequency loudness loss of the full-frequency unit, thereby effectively improving the full-frequency effect, making the external sound have stronger levels, and by arranging the sound emission normal line of the high-frequency unit 3 and the sound emission normal line of the full-frequency unit in different directions, sound propagation in a larger direction range can be realized, sound diffusion is stronger, that is, a larger sound field is generated, so that the audio column loudspeaker 901 has better sound quality effect, and users can obtain better experience.

[0090] Further, the second cavity 905 in the embodiment can be provided with a lifting assembly, and the lifting assembly is connected with the audio column loudspeaker 901 to drive the audio column loudspeaker 901 to extend out of the second cavity 905 or be stored in the second cavity 905.

The above-mentioned elastic pressing assembly is a prior art, and the embodiment will not be described in detail.

[0093] Further, the sound box 9 in the embodiment further comprises a display screen 907, a control circuit board, a microphone and a microphone receiving structure 906.

[0094] The display screen 907 is hinged to the shell 902, and the shell 902 is provided with a receiving bin on the outer wall surface thereof for receiving the display screen 907, which is recessed into the interior of the shell 902. When the display screen 907 rotates to a preset angle relative to the shell 902, the display screen 907 is received in the receiving bin and flush with the outer wall surface of the shell 902.

[0095] The control circuit board is installed in the interior of the shell 902, and the speaker assembly, the sound column speaker 901, the display screen 907 and the lifting assembly of the microphone receiving structure 906 are electrically connected with the control circuit board. The control circuit board is further electrically connected with a communication module, and the microphone of the microphone receiving structure 906 is wirelessly connected with the control circuit board through the communication module.

[0096] It should be noted that the microphone is connected with the control circuit board through the communication module, so that the voice signal of the user can be converted into a speaker broadcast after being processed by the control circuit board.

[0097] In addition, in the sound box 9 in the embodiment, when the microphone has two or more than two, the user can control two or more than two microphones to be synchronously lifted or individually lifted according to the selection. The above-mentioned process can be realized by program input in the control circuit board, which can be realized by the person skilled in the art, and the embodiment will not be described in detail.

[0098] Further, the display screen 907 in the embodiment can be opened by electricity or manually, and the embodiment does not limit this, and the designer can design according to the actual needs. In addition, in the embodiment, the display screen 907 can be linked with the lifting assembly through the control circuit board, that is, the display screen 907 is opened, and the lifting assembly drives the microphone to rise at the same time.

In this way, after the display screen 907 is closed, the microphone is completely covered by the display screen 907 and is completely stored in the shell 902 of the sound box 9.

[0101] Further, when the microphone is in communication with the sound box 9, for example, the microphone is too close to the sound box 9, which will cause the speaker to howl, and the loud and piercing howling sound of the speaker will greatly affect the user experience. Especially in the case of storing the microphone in the sound box 9, the probability of howling caused by the impact and friction sound during the storage of the microphone is higher. The microphone can be automatically turned off when stored in the storage slot, and the howling can be prevented during the process of the microphone approaching the sound box 9 or the sound box 9 storing the microphone.

[0102] In some embodiments, the way to automatically turn off the microphone is that the sensing element senses the distance between the sound box 9 and the microphone, and when the distance between the sound box 9 and the microphone is less than or equal to a preset distance, the microphone is automatically turned off. The sensing element can be one or more, and can be a Hall element, a distance sensor, an infrared sensor, and any other single electronic element that can sense the distance between the sound box 9 and the microphone, as well as any combination of electronic elements. The sensing element can be arranged on the sound box 9 and / or the microphone. Specifically, when the microphone is inserted into the receiving slot, the sensing element can be arranged at the opening of the receiving slot, so that the microphone is turned off for the first time when it is just inserted into the opening. The sensing element can also be arranged at the end of the receiving slot away from the opening, to prevent the sensing element from being exposed and aging due to the opening facing outward.

[0103] In one specific embodiment, the sensing element is a Hall element, and the sound box 9 receiving structure and the microphone each has a corresponding position. The microphone corresponding position is provided with a magnetic member, and the sound box 9 corresponding position is provided with a Hall element, or the microphone corresponding position is provided with a Hall element, and the sound box 9 corresponding position is provided with a magnetic member. The triggering condition of the Hall element can be that the detected magnetic field strength reaches a preset value. When the detected magnetic field strength is greater than or equal to the preset value, it means that the distance between the sound box 9 and the microphone meets the condition of causing howling, and the microphone needs to be turned off. Preferably, the microphone corresponding position is provided with a magnetic member, and the sound box 9 corresponding position is provided with a Hall element. Since the microphone is moved randomly during karaoke, it may be moved to other places with a relatively large magnetic field strength. The Hall element arranged on the microphone may cause the microphone to be turned off incorrectly, thereby affecting the experience. When the microphone is inserted into the receiving slot, the Hall element is arranged at the opening of the receiving slot of the housing 902 or at the end away from the opening.

[0104] In another specific embodiment, the sensing element is a Hall element, the sound box 9 is provided with a charging structure, and the microphone 4 is provided with a power receiving structure. The triggering condition of the Hall element can be the change of the magnetic field caused by the power-on moment when the microphone is charging. When the change of the magnetic field is detected, it means that the distance between the sound box 9 and the microphone meets the condition of causing howling, and the microphone needs to be turned off. The charging structure can be arranged on the surface of the sound box 9 or can be arranged corresponding to the receiving slot. The microphone can be inserted into the receiving slot, and the charging structure is arranged at the end of the receiving slot away from the opening of the housing 902. The microphone is provided with a power receiving structure at the bottom or the end of the microphone. The Hall element is arranged near the charging structure, and the Hall element can sense the change of the magnetic field caused by the power-on moment.

[0105] In the microphone storage structure 906 of the embodiment, when the user needs to use the microphone, the microphone can be automatically extended out of the opening of the storage through slot by controlling the lifting assembly, at this time, the user can directly take out and use the microphone; when the user does not need to use the microphone, the user directly inserts the microphone into the storage through slot, and then the lifting assembly drives the microphone to automatically descend and store in the storage through slot. Through the above design, the microphone can be simply and directly taken out and placed, the difficulty of taking out and placing is greatly reduced, the taking out and placing efficiency is effectively improved, and good use experience is brought to the user.

[0106] The sound post loudspeaker and the intelligent device are described in detail above, and for the general skilled in the art, the specific implementation manners and application ranges will be changed according to the idea of the embodiment of the utility model, and the content of the specification should not be understood as the limitation of the utility model.
