Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent square speaker acoustic detection, and in particular to an intelligent speaker acoustic detection device. Background Art

[0002] The smart square speaker is a smart home device that integrates voice recognition technology and artificial intelligence technology. It can interact with users through voice commands to achieve various functions. The acoustic detection device is mainly used to systematically detect and analyze the acoustic performance, sound quality, sound pickup ability and structural reliability of audio equipment such as smart square speakers to ensure the audio quality and user experience of the equipment in various scenarios.

[0003] When evaluating the sound quality of a square speaker, judging the quality of its "timbre" requires the use of professional acoustic testing equipment. The equipment evaluates the timbre by quantitatively analyzing various acoustic parameters of the sound. Existing equipment usually places the square speaker in an anechoic chamber or semi-anechoic chamber during testing. The sound emitted by the square speaker is received and analyzed by an audio analyzer to obtain the directional data of the square speaker's sound. However, since the sound radiation of the square speaker is not omnidirectional, especially the high frequency, it may be concentrated in a certain direction. If the sound is only detected in the front, the frequency response in other directions will be attenuated, resulting in a change in the timbre, such as: missing high frequencies, dim sound, etc. The audio analyzer cannot fully receive the sound emitted by the square speaker. Moreover, when a square speaker emits sound in a soundproof chamber, the reciprocating motion of the speaker unit will inevitably drive the box to generate mechanical vibrations, which may induce resonance. The resonance will significantly increase the vibration amplitude of the box, which will be transmitted to the audio analyzer through air coupling or the supporting structure, resulting in the audio analyzer being unable to accurately receive the sound. For this reason, the present invention provides an intelligent speaker acoustic detection device. Summary of the Invention

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figures 1 to 5 As shown, an intelligent speaker acoustic detection device according to an embodiment of the present invention includes a muffler shell 1, a base 3 is fixedly connected to the bottom of the muffler shell 1, a sealing door 2 is slidably connected to the surface of the muffler shell 1, and a fixing component 4 for fixing the square speaker is configured inside the muffler shell 1; The fixing assembly 4 includes a first telescopic cylinder 401, and a hinged plate 402 is hingedly connected to the top of the first telescopic cylinder 401 through a hinged rod. One end of the hinged plate 402 is hingedly connected to a splint 403 through a hinged rod. A slide plate 404 is fixedly connected to the bottom of the splint 403, and the bottom surface of the slide plate 404 is slidably connected to a base plate 406. The side of the base plate 406 is fixedly connected to the shell 12, and a group of support plates 405 is arranged between the two groups of splints 403.

[0021] The present invention takes into account that when performing acoustic testing on a square speaker, the square speaker is usually fixed after being placed, which can prevent the vibration of the speaker from resonating with the air when the square speaker emits sound, thereby affecting the effect of receiving sound from the square speaker. Even after the square speaker is fixed, the vibration generated by the reciprocating motion of the speaker may continue to resonate with the structure used to fix it, which will still affect the effect of receiving sound from the square speaker. Therefore, the square speaker is first placed above the multiple groups of clamping plates 403, and then the first telescopic cylinder 401 is activated to drive the hinged plate 402 to swing around the hinged rod. The swing of the hinged plate 402 pulls the clamping plate 403 to slide through the hinged rod, thereby clamping the four sides of the square speaker and fixing the square speaker. It should be noted that when the clamping plate 403 slides, the sliding plate 404 below it slides on the surface of the bottom plate 406, making the bottom of the square speaker hollow. At this time, even if the square speaker vibrates when making a sound, the vibration can only be transmitted to the position of the clamping plate 403. Since the clamping plate 403 is set in an L shape, it can fully contact the surface of the square speaker. When the square speaker vibrates, there will be no gap between the clamping plate 403 and the square speaker. The multiple groups of clamping plates 403 and the square speaker can be "integrated", which can reduce the vibration generated by the square speaker when making a sound to a certain extent, thereby improving the subsequent sound reception effect of the square speaker. It needs to be explained again that when the splint 403 is tightly attached to the four sides of the square speaker, the position of the splint 403 will be close to the center of the shell 12. At this time, the side of the splint 403 is not completely attached to the side of the support plate 405. Moreover, since a group of support plates 405 is arranged between the two groups of splints 403, even if the splint 403 vibrates to a certain extent and is transmitted to the position of the support plate 405, the amplitude of the vibration is transmitted outward from the center of the shell 12. Since several groups of through holes are opened on the surface of the support plate 405, the amplitude of the vibration can be reduced again to a certain extent, thereby effectively reducing the vibration of the square speaker when it emits sound, avoiding the resonance between the vibration generated by the square speaker itself and the air and structure, affecting the subsequent sound reception effect, and improving the stability of the square speaker during the acoustic detection process. At the same time, the clamping movement of multiple groups of splints 403 can also clamp square speakers of different sizes, and has a wide range of applications.

[0022] like Figures 1 to 2 and Figure 6 As shown, a matching component 8 for adjusting the angle of sound emitted by the square speaker after it is fixed is configured below the shell 12. The matching component 8 includes a third motor 801. The output end of the third motor 801 is fixedly connected to a worm 802. One side of the worm 802 is meshedly connected to a worm gear 803. The lower part of the worm gear 803 is rotatably connected to a fixed bottom sleeve 804. The upper end surface of the fixed bottom sleeve 804 is fixedly connected to the lower end surface of the shell 12, and the shell 12 is telescopically arranged.

[0023] During operation, after the square speaker is placed on top of the splint 403 and fixed, the square speaker may continue to emit sound in the same direction during the detection process, and it is not possible to fully receive the sound emitted by the square speaker in different directions. At this time, the range of sound reception of the square speaker is reduced, and the quality of acoustic detection is reduced. Therefore, after the square speaker is limited and fixed, the third motor 801 is started to rotate to drive the worm 802 to rotate, and the worm 802 engages in transmission to drive the worm gear 803 to rotate. The rotation of the worm gear 803 can drive the outer shell 12 to rotate. When the outer shell 12 rotates, its internal structure can also rotate, so that the square speaker clamped by the splint 403 also rotates, and the square speaker can be adjusted 360°, and can receive sounds emitted by the square speaker in different directions, which can improve the range of acoustic detection of the square speaker. It should be noted that due to the self-locking characteristics between the worm 802 and the worm wheel 803, after the sound direction of the square speaker is changed, when the square speaker makes a sound, the fixed bottom sleeve 804 and the outer shell 12 fixed above it can maintain their position firmly without displacement, which significantly improves the stability of the square speaker after the angle adjustment. Moreover, after the angle of the square speaker is adjusted through the transmission of the worm 802 and the worm wheel 803, in the self-locking state, the transmission pair between the worm 802 and the worm wheel 803 will form a rigid fixed constraint. This constraint can improve the overall stiffness of the connection between the fixed bottom sleeve 804 and the outer shell 12, suppress the vibration generated when the square speaker makes a sound, and can perform vibration reduction treatment again, which can effectively improve the stability of the splint 403 after clamping the square speaker, and improve its vibration reduction effect on the square speaker, thereby avoiding the occurrence of resonance.

[0024] like Figures 7 and 8 As shown, an audio analyzer 6 for receiving sound emitted by the square speaker is installed inside the silencer housing 1. An adjustment component 5 for adjusting the sound receiving position of the audio analyzer 6 is configured above the fixing component 4. The adjustment component 5 includes a first motor 501. The output end of the first motor 501 is fixedly connected to a ring gear 502. The inner side of the ring gear 502 is meshed with a mating gear 504. The inner surface of the mating gear 504 is meshed with a central gear 509. A connecting rod 503 is fixedly connected below the ring gear 502. A transmission gear 505 is fixedly connected below the mating gear 504. A direction-changing gear 506 is meshed on one side of the transmission gear 505. The audio analyzer 6 is rotatably mounted below the connecting rod 503.

[0025] During operation, after the direction of the sound emitted by the square speaker is adjusted, the sound emitted by the square speaker will be received by the audio analyzer 6, thereby detecting the acoustics of the square speaker. However, when the square speaker is emitting sound, it is necessary to receive sounds from different positions, for example, receiving sounds from the back and both sides of the square speaker. At this time, if the square speaker is adjusted to rotate, the sound may resonate between the structure and the air due to the movement of the fixed bottom sleeve 804 and the outer shell 12, thereby reducing the effect of receiving the sound of the square speaker. Therefore, by starting the first motor 501 to rotate and drive the ring gear 502 to rotate, the rotation of the ring gear 502 can drive the connecting rod 503 and the audio analyzer 6 below to rotate, so that the audio analyzer 6 can perform a circular motion inside the silencer shell 1, and the position of the audio analyzer 6 to receive the sound emitted by the square speaker can be adjusted, thereby improving the range of acoustic detection of the square speaker. It should be noted that when the audio analyzer 6 performs a circular motion to adjust the position for receiving sound, in order to prevent the audio analyzer 6 from changing its orientation during the motion, for example, when the audio analyzer 6 rotates to a certain position toward the inside of the muffler housing 1, the ring gear 502 engages with the mating gear 504 to rotate. The rotation of the mating gear 504 engages with the center gear 509. Since the center gear 509 is stationary, the mating gear 504 also revolves during its own rotation, thereby driving the transmission gear 505 to rotate synchronously. The rotation of the transmission gear 505 engages with the direction-changing gear 506 on the surface of the connecting rod 503 to rotate. The rotation of the direction-changing gear 506 drives the audio analyzer 6 to rotate in the opposite direction to the ring gear 502, thereby offsetting the torque when the ring gear 502 drives the audio analyzer 6 through the connecting rod 503. This ensures that the audio analyzer 6 always faces the center of the housing 12, effectively improving the accuracy of capturing the sound emitted by the square speaker and enhancing the sound reception effect.

[0026] like Figures 7 and 8 As shown, a mounting plate 507 is fixedly connected to the bottom of the direction-changing gear 506, and the audio analyzer 6 is installed below the mounting plate 507. The transmission gear 505 engages with the transmission to drive the direction-changing gear 506 to rotate on the surface of the connecting rod 503. The ring gear 502 drives the audio analyzer 6 below the mounting plate 507 to perform circular motion through the connecting rod 503. A partition 508 is slidably engaged with the surface of the connecting rod 503. The partition 508 is fixedly connected to the housing 12, and the ring gear 502 is rotatably connected to the housing 12.

[0027] During operation, when the direction-changing gear 506 rotates, it drives the mounting plate 507 to rotate. The rotation of the mounting plate 507 drives the audio analyzer 6 to rotate in the opposite direction, thereby adjusting the angle at which the audio analyzer 6 receives sound. When the square speaker emits sound, the movement of the audio analyzer 6 not only allows it to always receive sound in the direction of the square speaker, but also, because the audio analyzer 6 is in a state of continuous movement during the adjustment process, it can better simulate the accuracy of sound reception when a person is walking, and can better receive sound from different directions. It should be noted that, since the bottom of the center gear 509 is fixed above the partition 508, the partition 508 and the housing 12 are fixedly connected. At this time, when the matching gear 504 rotates, it will perform a circular motion around the center gear 509, thereby driving the transmission gear 505 to also perform a circular motion, so that the transmission gear 505 can always be engaged with the changing gear 506, thereby adjusting the position of the audio analyzer 6, making it convenient for the audio analyzer 6 to receive sounds emitted by the square speaker in different directions, which can effectively improve the sound reception range of the audio analyzer 6, make the detection more humane, and improve the quality of the acoustic detection of the square speaker.

[0028] like Figures 9 and 10 As shown, the interior of the base 3 is configured with an auxiliary component 7 for adjusting the position of the speaker, and the auxiliary component 7 includes a second motor 701, and the output end of the second motor 701 is fixedly connected to a screw 702, and the screw 702 is rotatably connected to the base 3. The surface of the screw 702 is threadedly connected to a moving block 703, and one side of the moving block 703 is fixedly connected to a sliding rod 704, and the surface of the sliding rod 704 is slidably connected to a mounting block 707, and the upper part of the mounting block 707 is slidably connected to a limiting plate 705.

[0029] During operation, after adjusting the sound emission angle of the square speaker and the direction of reception by the audio analyzer 6, in order to further perform all-round acoustic detection on the sound emitted by the square speaker, the rotation of the second motor 701 drives the screw 702 to rotate, and the screw 702 threaded transmission drives a group of moving blocks 703 to move left and right. The left and right movement of the moving block 703 can drive the slide bar 704 to move, and the movement of the slide bar 704 drives the mounting block 707 to slide inside the base 3. The sliding of the mounting block 707 can drive the fixed bottom sleeve 804 to move, thereby driving the adjustment of the entire square speaker in the left and right direction, and can make the square speaker move to or away from the position close to the center of the sound-absorbing shell 1. This can effectively improve the audio analyzer 6 to receive sounds emitted by the square speaker in different directions at different positions, further accurately receive and detect the sounds emitted by the square speaker, receive and analyze sounds at different positions, and have a wide detection range. It should be noted that when the mounting block 707 moves to a certain position in the left-right direction, another set of second motors 701 is started to drive the moving block 703 to move in the front-back direction. The movement of the other set of moving blocks 703 can drive the limiting plate 705 to move. The movement of the limiting plate 705 can drive the movement of the mounting block 707 in the front-back direction, so that the fixed bottom sleeve 804 above the mounting block 707 can be adjusted in four directions, front-back, left-right, and right-hand directions, thereby adjusting the position of the square speaker. Moreover, since one end of the sliding rod 704 and the limiting plate 705 is fixedly connected to the moving block 703 and the other end is slidably connected to the inner side of the base 3, after the position of the mounting block 707 is adjusted, the fixed bottom sleeve 804 above the mounting block 707 can always remain stationary, thereby improving the stability of the support for the square speaker. It needs to be explained again that by arbitrarily adjusting the angle and position of the sound emitted by the square speaker and the position at which the audio analyzer 6 receives the sound, it is possible to fully simulate the effect of the audio analyzer 6 receiving the sound at different positions after the square speaker emits the sound, thereby being able to fully detect the quality of the sound emitted by the square speaker and determine whether the acoustic test of the square speaker meets the standards, thereby effectively improving the quality and efficiency of the acoustic test of the square speaker.

[0030] like Figures 9 and 10 As shown, the surface of the slide rod 704 is slidably connected with two sets of sleeve rods 706, the upper ends of the sleeve rods 706 are fixedly connected to the fixed bottom sleeve 804, the second motor 701 is fixedly installed inside the base 3, and the screw 702 drives the slide rod 704 and the limit plate 705 to move left and right and front and back through the moving block 703. A sliding groove is provided inside the limit plate 705, and the mounting block 707 is slidably connected to the limit plate 705 through the upper cylinder.

[0031] During operation, since the slide bar 704 is cylindrical, when the slide bar 704 drives the mounting block 707 to move in the left and right directions, in order to avoid position offset between the mounting block 707 and the slide bar 704, thereby affecting the normal movement of the fixed bottom sleeve 804, two sets of sleeve rods 706 are set below the fixed bottom sleeve 804, and the bottoms of the two sets of sleeve rods 706 slide on the surface of the slide bar 704. When the slide bar 704 moves, the two sets of sleeve rods 706 limit the mounting block 707 to move smoothly, thereby improving the stability of the square speaker during movement. After the fixed bottom sleeve 804 is placed and offset, it cannot effectively support structures such as the splint 403, thereby effectively suppressing the vibration generated by the square speaker, and improving the accuracy of the audio analyzer 6 in receiving and collecting sound.

[0032] like Figure 2 and Figure 11 As shown, a cooling assembly 9 is provided inside the outer shell 12, and the cooling assembly 9 includes an air conditioner 901. A ring pipe 902 is connected above the air conditioner 901, and a plurality of groups of air outlet pipes 903 are fixedly connected above the ring pipe 902. The upper end of the air outlet pipe 903 is arranged in an arc shape, and the through hole inside the support plate 405 is opened at an angle.

[0033] During operation, considering that the square speaker may generate a certain amount of heat when receiving and analyzing sounds that require the square speaker to work for a long time, thus causing damage, the movement of the air cooler 901 generates cold air, which is transported from the ring pipe 902 to the inside of the air outlet pipe 903, and then output from the air outlet pipe 903 to the bottom of the support plate 405, and then transported from the through-hole inside the support plate 405 to the hollow position at the bottom of the square speaker, which can effectively dissipate heat for the square speaker. It should be noted that by setting the annular tube 902 into a spiral shape, it is possible to effectively avoid the friction between the air and the inner wall of the pipe when the cold air is continuously transported to the bottom of the square speaker through the straight pipe, thereby causing noise and affecting the audio analyzer 6's reception of sound. In addition, by setting the upper part of the outlet pipe 903 into an arc shape, when the cold air is sprayed from the outlet pipe 903 to the bottom of the support plate 405, the flow rate of the cold air can be slowed down again, thereby avoiding the generation of large noise and affecting the sound collection effect of the audio analyzer 6. It needs to be explained again that since the through holes inside the support plate 405 are opened at an angle, when the cold air flows upward from the bottom, part of the cold air will be guided to the surrounding areas of the square speaker by the through holes inside the support plate 405, and when the cold air flows through the through holes inside the support plate 405, since the square speaker is in a sounding state at this time, the support plate 405 will be subjected to a certain vibration. At this time, the cold air will not only be dispersed under the amplitude of the vibration, reducing the noise generated when the cold air flows from the inside of the through hole, but can also effectively make the cold air evenly discharged from the inside of the through hole, which can effectively improve the heat dissipation effect of the square speaker.

[0034] like Figures 1 to 3 and Figure 6 As shown, a second telescopic cylinder 10 is installed inside the air conditioner 901, and the lower end of the second telescopic cylinder 10 is fixedly connected to the outer shell 12, and the output end of the second telescopic cylinder 10 is fixedly connected to the bottom end of the first telescopic cylinder 401. The movement of the second telescopic cylinder 10 can drive the first telescopic cylinder 401 to move upward, and the outer shell 12 is telescopically arranged above the fixed bottom sleeve 804. The movement of the first telescopic cylinder 401 drives the outer shell 12 to telescopically move. The output end surface of the second telescopic cylinder 10 is slidably connected to the fixed plate 11, and the fixed plate 11 and the outer shell 12 are fixedly connected.

[0035] During operation, in order to further improve the range of sound reception of the square speaker, the movement of the second telescopic cylinder 10 can drive the first telescopic cylinder 401 to move upward, the movement of the first telescopic cylinder 401 can drive the housing 12 to perform telescopic movement, the movement of the housing 12 can drive the bottom plate 406 to move, and the movement of the bottom plate 406 can drive the square speaker clamped by the multiple groups of clamps 403 to move upward, so that the height of the square speaker can be adjusted, and the vertical distance between the square speaker and the audio analyzer 6 can be adjusted, which can better improve the range of sound reception of the audio analyzer 6 when the square speaker emits sound, and improve the authenticity of the acoustic detection of the square speaker; It should be noted that when the position of the square speaker is moved upward and adjusted, although the shell 12 performs telescopic movement, since the lower end of the shell 12 is fixedly connected to the fixed bottom sleeve 804, the internal structure of the shell 12 can be regarded as "a whole" at this time. Even if the height of the square speaker is adjusted, it will not affect the angle adjustment of the square speaker's sound, which can effectively improve the stability of the square speaker under different adjustment operations.

[0036] like Figure 11 As shown, the inclined square at the arc-shaped air outlet above the air outlet pipe 903 is consistent with the inclination direction of the through hole opened inside the support plate 405, and shock-absorbing cotton is installed on the surface of the splint 403 on both sides of the support plate 405. The support plate 405 is made of vibration-reducing material, and the air outlet pipe 903 is evenly distributed directly below the support plate 405.

[0037] During operation, since the inclined square shape at the arc-shaped air outlet above the air outlet pipe 903 is in the same inclination direction as the through-holes opened inside the support plate 405, when the cold air flows out from the top of the air outlet pipe 903, the cold air will quickly flow to the through-holes opened inside the support plate 405, thereby dispersing the cold air. This can effectively prevent a large amount of cold air from contacting the heated square speaker and forming water droplets on the surface of the square speaker, thereby improving the heat dissipation effect of the square speaker. It should be noted that the multiple groups of air outlet pipes 903 are evenly distributed and arranged just below the support plate 405, which can prevent the cold air from flowing out of the air outlet pipes 903 and directly flowing to the bottom of the square speaker, thereby forming water droplets to damage the square speaker. In addition, by making the support plate 405 with vibration-reducing material, the vibration generated by the square speaker can be reduced. At this time, since the support plate 405 is performing vibration reduction work on the square speaker, the vibration amplitude of the support plate 405 is small, and the cold air will not be fully "dispersed", thereby avoiding the cold air from losing its effect and being unable to dissipate heat for the square speaker, which can further improve the heat dissipation effect of the square speaker.

[0038] like Figures 9 and 10 As shown, the slide rod 704 and the limit plate 705 are made of wear-resistant material. When the slide rod 704 drives the mounting block 707 to adjust the left and right directions, the limit plate 705 can also move to drive the mounting block 707 to move in an "arc shape". The screw rod 702 is connected to the base 3 for rotation, and the moving block 703 is connected to the base 3 for sliding.

[0039] During operation, when the position of the square speaker needs to be adjusted, the two sets of second motors 701 can be started at the same time to move through the slide bar 704 and the limit plate 705 to drive the mounting block 707 to move. At this time, the mounting block 707 will move in an "arc-shaped" motion trajectory under the synchronous action of the slide bar 704 and the limit plate 705. At this time, the movement of the mounting block 707 can drive the square speaker to adjust to any position, thereby facilitating the audio analyzer 6 to receive the sound emitted by the square speaker at any position. This not only facilitates the adjustment of the position of the square speaker, but also further improves the effect and quality of the sound reception of the audio analyzer 6, and has a wide detection range.
