Technical Field

[0001] This utility model relates to the field of speaker technology, and in particular to an intelligent speaker system. Background Technology

[0002] A speaker is a device that converts audio signals into sound. Speakers used in multi-person settings such as karaoke and square dancing are typically equipped with screens for user operation and to view lyrics. However, due to the open space and large number of singers, the speaker screen may be misaligned with the singer when they move around or when different people are singing. This can prevent the screen from being directly facing the singer, making it difficult for them to see the screen and lyrics, causing inconvenience.

[0003] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an intelligent speaker system to solve the problem that the screen of the existing speaker system cannot follow the user's rotation, making it difficult for the user to see the screen and lyrics.

[0008] In a further embodiment of this invention, the signal receivers are arranged in a ring array within the speaker body.

[0009] A further feature of this invention includes a position sensing module connected to the signal receiving and processing module, used to detect the rotational position of the screen.

[0010] In a further embodiment of this invention, the position sensing module includes at least one Hall sensor, which forms a Hall sensing area on the speaker body, and the Hall sensor is connected to the second control unit. The screen is equipped with magnetic blocks; When the magnetic block enters the Hall sensing area, the Hall sensor outputs the position signal of the screen to the second control unit.

[0031] Please also refer to Figures 1 to 7 This utility model provides a preferred embodiment of an intelligent speaker system.

[0032] In some embodiments, such as Figure 1 , Figure 2 and Figure 3As shown, this utility model provides an intelligent speaker system, which includes: a speaker body 1, a microphone 3, and a positioning and drive control system. A rotatable screen 2 is disposed on the speaker body 1; the microphone 3 is separately disposed from the speaker body 1. The positioning and drive control system includes: a signal transmitting module 110, a signal receiving and processing module 120, and a screen driving module 130. The signal transmitting module 110 is disposed on the microphone 3 and is used to transmit a positioning signal; the signal receiving and processing module 120 is disposed on the speaker body 1 and is used to receive the positioning signal, determine the position of the microphone 3 corresponding to the speaker body 1 based on the positioning signal, and generate a corresponding screen driving signal; the screen driving module 130 is disposed on the speaker body 1 and connected to the signal receiving and processing module 120 and the screen 2, and is used to respond to the screen driving signal and drive the screen 2 to rotate to a target position corresponding to the position of the microphone 3.

[0033] In this embodiment, a pair of microphones 3 are generally provided, with both microphones 3 being separately disposed from the speaker body 1, and each microphone 3 having a signal transmission module 110. In this embodiment, the speaker body 1 can be regarded as the master device, and the microphones 3 can be regarded as slave devices.

[0034] The screen 2 is mounted on the speaker body 1 and can rotate 360° on top of the speaker body 1 under the drive of the screen driving module 130. The signal receiving and processing module 120 is located inside the speaker body 1 and can receive the positioning signal emitted by the signal transmitting module 110 inside the microphone 3. Based on the positioning signal, it determines the position of the microphone 3 relative to the speaker body 1, and simultaneously generates a corresponding screen 2 driving signal and sends it to the screen driving module 130. The screen driving module 130 responds to the screen driving signal and drives the screen 2 to rotate to the target position corresponding to the position of the microphone 3.

[0035] In the above technical solution, this utility model transmits a positioning signal to the signal receiving and processing module 120 in the speaker body 1 through the signal transmitting module 110 in the microphone 3. Subsequently, the signal receiving and processing module 120 determines the position of the microphone 3 relative to the speaker body 1 based on the positioning signal and generates a corresponding screen 2 driving signal. The screen driving module 130 responds to the screen 2 driving signal and rotates the screen 2 to the target position corresponding to the position of the microphone 3. Thus, when the singer moves in an open area or when people in different directions sing, the screen 2 can rotate with the singer, ensuring that the screen 2 is directly facing the singer. This makes it easier for the singer to see the screen 2 and the lyrics, enhancing the interactivity between the user and the screen 2, and improving the user's singing experience.

[0036] In some embodiments, such as Figure 1 and Figure 6 As shown, the signal transmitting module 110 includes: a trigger unit 111, a first control unit 112, and a signal transmitter 113. The trigger unit 111 is connected to the first control unit 112, and the trigger unit 111 is used to cause the first control unit 112 to output a first control signal when it is in a triggered state; the first control unit 112 is connected to the signal transmitter 113, and the first control unit 112 is used to output the first control signal to the signal transmitter 113; the signal transmitter 113 is used to transmit a positioning signal when it receives the first control signal.

[0037] In this embodiment, the trigger unit 111 is disposed on the microphone 3 and connected to the first control unit 112. When the trigger unit 111 is triggered by the user, it outputs a trigger signal (generally a high-level signal) to the first control unit 112. The first control unit 112 responds to the trigger signal and outputs a first control signal to the signal transmitter 113. After receiving the first control signal, the signal transmitter 113 transmits a positioning signal. In one implementation, the trigger unit 111 can be a push-button switch. When the push-button switch is pressed by the user, the first control unit 112 outputs a first control signal to the signal transmitter 113.

[0038] In some embodiments, such as Figure 1 and Figure 7 As shown, the signal receiving and processing module 120 includes: a second control unit 121 and a plurality of signal receivers 122. The signal receivers 122 are connected to the second control unit 121 and are used to receive positioning signals emitted by the signal transmitter 113. The second control unit 121 is connected to the screen driving module 130 and is used to determine the orientation of the microphone 3 based on the phase difference or time difference of the positioning signals reaching different signal receivers 122.

[0039] In this embodiment, the signal receiving and processing module 120 consists of a second control unit 121 and a signal receiver 122. When the signal transmitter 113 transmits a positioning signal, the signal receiver 122 receives the positioning signal and sends it to the second control unit 121. Several signal receivers 122 are provided, and each signal transmitter 113 receives the positioning signal at a different time. The second control unit 121 can determine the location of the microphone 3 based on the phase difference or time difference of the positioning signal reaching different signal receivers 122. It should be noted that after receiving the user's specific location, the second control unit 121 processes the received signal. The second control unit 121 has a preset orientation program, such as a control program for rotation direction and speed.

[0040] In some embodiments, such as Figure 1 , Figure 6 and Figure 7 As shown, the signal transmitter 113 can be an ultrasonic transducer, the positioning signal is an ultrasonic signal, and correspondingly, the signal receiver 122 is an ultrasonic transducer.

[0041] In practical implementation, the signal receiving and processing module 120 in the speaker body 1 first needs to distinguish which microphone 3 is in use. When multiple microphones 3 are used, the speaker body 1 acts as the master device, and the microphones 3 act as slave devices. Generally, different microphones 3 are distinguished by fixed and different frequencies. Taking two microphones 3 as an example, the 100kHz microphone 3 is designated as label one, and the 150kHz microphone 3 is designated as label two. Then the master device can identify different people (i.e., different microphones 3) by receiving sound waves of different frequencies. When one microphone 3 is pressed, the signal receiver 122 receives the intensity of the ultrasonic waves from different directions of the microphone 3, thereby determining the position of the microphone 3 and determining the direction in which the user needs to rotate. When two microphones 3 are pressed simultaneously, the signal receiver 122 compares the intensity of the ultrasonic signals of the microphones 3, determines that the microphone 3 with the higher signal intensity is the microphone 3 that needs to be rotated, and then rotates according to the direction of that microphone.

[0042] For example, when the speaker body 1 confirms that the microphone 3 emitting the positioning signal is a 100kHz microphone, each of the signal receivers 122 in the speaker body 1 receives the ultrasonic signal of the microphone 3 at the corresponding frequency and feeds it back to the second control unit 121. The second control unit 121 determines the location of the corresponding microphone 3 according to the phase difference or time difference of the positioning signal reaching different signal receivers 122.

[0043] In other embodiments, the positioning signal may also be a radio wave of a specific frequency, etc. The working principle of the positioning signal as a radio wave is similar to that of the positioning signal as an ultrasonic signal, and will not be described again here.

[0044] In some embodiments, such as Figure 4 As shown, the signal receivers 122 are arranged in an array in a ring within the speaker body 1.

[0045] In this embodiment, the signal receiver 122 is placed inside the speaker body 1. To achieve omnidirectional recognition, multiple signal receivers 122 are generally required. In this embodiment, the signal receivers 122 are arranged in a circular array within the speaker body 1, so that the speaker body 1 can receive positioning signals emitted by the signal transmitter 113 from all directions.

[0046] It is understandable that the signal receivers 122 are arranged in a ring to form a ring array ultrasonic device. The more ring array ultrasonic sensors there are, the higher the accuracy of the machine in sensing the position of the object. Figure 5 As shown, the space is divided into 6 equal parts of 360°, each region being 60°, respectively. An ultrasonic sensor is placed inside. In consumer electronics products such as smart home appliances and robots, ultrasonic sensors are generally designed to be relatively small in size to accommodate the thinner and smaller designs of these products.

[0047] For example, the array-type ultrasonic transducer device of the speaker body 1 has 120 subdivisions. Then, there are 30 corresponding to each of the four sides, and the angle of each corresponding one is 90 / 30=3°. When the sound wave frequency is greater than 20KHZ, the wavelength is short and the diffraction phenomenon is weak. At this time, the sound wave is considered to have the directionality of a beam. When the user is on the back of the speaker body 1, the microphone 3 in the user's hand emits an ultrasonic signal to the signal receiving and processing module. The signal receiving and processing module 120 of the speaker compares the signal values ​​of the 30 ultrasonic transducers in each side, selects the few with the strongest signals, and determines the relative position of the user and the speaker body 1 at this time.

[0048] In some embodiments, the angle range of each rotation of the screen 2 is 15-60 degrees.

[0049] In this embodiment, the screen driving module 130 drives the screen 2 to rotate by an angle of 15-60°, for example, 15°, 30°, 60°, etc. Taking a rotation angle of 60° for each rotation of the screen 2 as an example, the rotation of the screen 2 divides the 360° space into 6 angles, and each rotation area is 60°. That is, the screen 2 can achieve 3 rotation angles within a 180° plane, such as... Figure 5As shown. By sensing the intensity of the ultrasonic signal from the user's microphone 3, the user's movement within each 60° area can be determined. When the user moves within one 60° area, it means that the user can view the screen 2 without rotating it. When the user moves to another 60° area, it means that the user needs to rotate the screen 2 to obtain a suitable angle, at which point the screen 2 rotates to the other 60° area.

[0050] In some embodiments, such as Figure 1 As shown, the smart speaker module also includes a third control unit 160, which is connected to the signal transmitting module 110. The third control unit 160 is used to output a second control signal to the signal transmitting module 110, so that the signal transmitting module 110 transmits a pause signal to the signal receiving and processing module 120, and causes the signal receiving and processing module 120 to generate a stop driving signal and send it to the screen 2 driving block.

[0051] In this embodiment, the microphone 3 is further equipped with a third control unit 160. When the third control unit 160 is triggered by the user, it sends a trigger signal (generally a high-level signal) to the first control unit 112. At this time, the first control unit 112 transmits a pause signal to the signal receiver 122 through the signal transmitter 113. The signal receiver 122 feeds back to the second control unit 121, which generates a stop drive signal and sends it to the screen drive module 130. The screen drive module 130 responds to the stop drive signal and stops driving the screen 2. Taking each rotation area of ​​the screen 2 as 60° as an example, when the screen 2 is normally rotating from the first 60° area to the second 60° area, the user can trigger the third control unit 160, so that the screen 2 can be moved to the position required by the user. In one implementation, the third control unit 160 is a pause button switch. When the pause button switch is pressed, the screen 2 can stop at the position required by the user, that is, the orientation of the screen 2 can be manually adjusted so that the position of the screen 2 corresponds more closely to the user's position.

[0052] In some embodiments, the third control unit 160 can also be used to implement other functions besides pausing the rotation of the screen 2. For example, when the third control unit 160 is triggered, it can control the speaker body 1 to be in a mute mode, or implement mode switching, such as switching between mute and playback modes.

[0053] In some embodiments, such as Figure 1 and Figure 3As shown, the smart speaker system also includes a position sensing module 140, which is connected to the signal receiving and processing module 120, and is used to detect the rotation position of the screen 2.

[0054] In this embodiment, the position sensing module 140 is disposed on the speaker body 1 and can sense the rotation position of the screen 2. When the screen 2 rotates one full circle, that is, 360°, considering the wiring issue, the screen 2 cannot rotate continuously in the same direction. That is, after the screen 2 has rotated one full circle, if it is necessary to further adjust the position of the screen 2 relative to the user, it is necessary to control the screen 2 to rotate in the opposite direction. When the position sensing module 140 detects that the screen 2 has rotated one full circle, it sends a stop signal to the second control unit 121. The second control unit 121 controls the screen driving module 130 to stop driving the screen 2 to rotate in the original direction. Taking a rotation angle of 60° as an example, when the screen 2 rotates in one direction to the last 60° area, the screen 2 stops rotating and detects the user's movement direction. If the user continues to move in the original direction, that is, after the user rotates 360° back to the origin, the screen 2 is controlled to reverse and return to the first 60° area.

[0055] In some embodiments, the position sensing module 140 includes at least one Hall sensor, which forms a Hall sensing area on the speaker body 1 and is connected to the second control unit 121; a magnetic block 150 is disposed on the screen 2. When the magnetic block 150 enters the Hall sensing area, the Hall sensor outputs a position signal of the screen 2 to the second control unit 121.

[0056] In this embodiment, the Hall sensor and the magnetic block 150 are used to detect the position of the screen 2. The magnetic block 150 is located directly below the Hall sensor. When only one Hall sensor is set, the magnetic block 150 is positioned opposite the Hall sensor. The sensing point of the Hall sensor is set as the starting point of rotation. When the screen 2 rotates clockwise, the magnetic block 150 slowly moves away from the Hall sensor area. When the magnetic block 150 returns to the Hall sensor area, it indicates that the screen 2 has rotated approximately 360°. At this point, the Hall sensor sends a stop signal to the second control unit 121 to stop the screen 2 from rotating. To achieve tracking with the microphone 3, the second control unit 121 controls the screen 2 to rotate in the opposite direction while detecting the user's movement direction. When the user moves back to the original direction, the sensed signal continuously strengthens, so the screen continues to rotate in that direction, controlling the screen 2 to return to its original position. The working principle when the screen 2 rotates counterclockwise is the same as when it rotates clockwise.

[0057] In some embodiments, two Hall sensors are provided.

[0058] In this embodiment, two Hall sensors are configured, spaced apart on the speaker body 1. When the screen 2 is detected rotating from the position of the first Hall sensor to the position of the second Hall sensor, it indicates that the screen 2 has rotated one full revolution. While the screen 2 rotates clockwise, this embodiment uses Hall sensing to limit the screen 2 to rotate in one direction. When the screen 2 rotates to the point where both Hall sensors generate signals to the second control unit 121, the second control unit 121 immediately stops the screen 2 from rotating. To achieve tracking with the microphone 3, the second control unit 121 controls the screen 2 to rotate in the opposite direction. If the sensed signal continuously increases during this process, the screen 2 will continue to rotate in that direction.

[0059] In some embodiments, the position sensing module 140 may also use an encoder or potentiometer to detect the rotation position of the screen 2. The detection principle is to count the rotation angle of the screen 2, and stop driving the screen 2 when the screen 2 is detected to rotate 360° or close to 360° (e.g., 350°).

[0060] In some embodiments, such as Figure 1 and Figure 7 As shown, the screen driving module 130 includes: a motor driving chip 131 and a driving motor 132; the motor driving chip 131 is connected to the second control unit 121 and the driving motor 132 respectively, and the motor driving chip 131 is used to drive the driving motor 132 according to the screen 2 driving signal; the driving motor 132 is connected to the screen 2, and the driving motor 132 is used to drive the screen 2 to rotate to the target position corresponding to the microphone 3.

[0061] In this embodiment, the parameters of the drive motor 132 need to be set: the motor rotation speed is always set to x rad / s, so the time for the screen 2 to rotate within each sensor sensing area is 60 / 360 = 0.167 / x (s). The Hall sensor point is set as the starting point of rotation, and the angle of one rotation of the screen 2 is 60°, so the time for the screen 2 to rotate through one 60° area is 0.167 / x (s). The time is incremented sequentially as the screen 2 rotates one revolution. As the drive motor 132 rotates clockwise, the time count increases continuously. When the screen 2 rotates to the point where both Hall sensors generate signals to the second control unit 121, the second control unit 121 immediately controls the motor to stop rotating.

[0062] In some embodiments, such as Figure 1 and Figure 6As shown, the first control unit 112 can employ a first control chip. When the first control chip detects that the push-button switch is pressed, it initializes the UART communication timing and outputs UART protocol electrical signals to the ultrasonic transducer at the microphone 3 end through the TX and RX pins. The ultrasonic transducer receives the protocol electrical signals through the TX and RX pins and emits ultrasonic signals of a specific frequency, i.e., positioning signals. In some embodiments, the first control chip can be an STM32F103C8T6 control chip, and the ultrasonic transducer at the microphone 3 end can be a URM06-UART signal ultrasonic transducer, which can amplify the signal so that the ultrasonic transducer in the speaker body 1 can receive the ultrasonic signal. In some embodiments, such as Figure 1 and Figure 7 As shown, the second control unit 121 uses a second control chip, which can be the same model as the first control chip. The ultrasonic transducer at the speaker body 1 can also be the same model as the ultrasonic transducer at the microphone 3.

[0063] In some embodiments, such as Figure 7 As shown, the motor driver chip 131 can be a BDR6122T motor driver chip 131, which can convert the PWM / level control signal into a large current signal sufficient to drive the motor 132.

[0064] In specific implementation, the ultrasonic transducer at the speaker body 1 receives the ultrasonic signal from the microphone 3. Through the built-in "real-time noise suppression algorithm", the ultrasonic signal is filtered and converted into a recognizable digital signal, and a UART protocol electrical signal is output to the second control chip. The second control chip receives and parses the UART protocol electrical signal through the TX port and RX port, and outputs a PWM / level control signal to the BDR6122T motor drive chip 131.

[0065] In some embodiments, such as Figure 7As shown, the Hall sensor can be a U1E191315-A23-T model Hall sensor, which can receive "magnetic field change signals" from the physical environment and convert the analog magnetic field signal into a voltage signal with an intensity of 0-1, and output it to the second control chip. The second control chip can determine the number of times the screen 2 rotates based on this voltage signal. When the second control chip detects a high signal of two screen 2 rotations, it determines that the screen 2 has rotated 360°, and at this time, it controls the drive motor 132 to stop rotating. When the user rotates 360° to the next 60° area, the ultrasonic transducer in that area senses the user's signal and sends a signal to the second control chip to achieve reversal. The Hall sensor continues to sense, and when it senses reversal twice, it also indicates a 360° rotation, and controls the drive motor 132 to stop rotating.

[0066] In some embodiments, such as Figure 3 As shown, the speaker body 1 is also provided with a power off button 11. When the user presses the power off button 11, the second control unit 121 determines the current counting state. If the screen 2 is in the forward rotation angle position at this time, a reverse callback is performed. If the screen 2 is in the reverse rotation angle position at this time, a forward callback is performed.

[0067] In some embodiments, such as Figure 8 As shown, this utility model also provides a method for controlling the responsiveness of a speaker screen, applicable to a system including a separate microphone and a speaker body with a rotatable screen. The method includes the following steps: S1. Receive the positioning signal transmitted by the microphone; Specifically, the microphone contains a signal transmitting module, and the speaker body contains a signal receiving and processing module. The signal receiving and processing module is capable of receiving positioning signals emitted by the signal transmitting module inside the microphone. In some embodiments, the positioning signal may be an ultrasonic signal or a radio signal.

[0068] S2. Based on the positioning signal, determine the orientation of the microphone relative to the speaker body; Specifically, the signal transmitting module includes a trigger unit, a first control unit, and a signal transmitter, and the signal receiving and processing module includes a second control unit and several signal receivers. Several signal receivers are provided, and each signal transmitter receives the positioning signal at a different time. The second control unit can determine the microphone's location based on the phase difference or time difference of the positioning signal reaching different signal receivers.

[0069] S3. Generate a corresponding screen driving signal based on the orientation; Specifically, the screen driving module can drive the screen to the corresponding position according to the screen driving signal. In other words, the orientation signal generated by the second control unit according to the positioning signal corresponds to the screen driving signal.

[0070] S4. In response to the screen driving signal, drive the screen to rotate to the target position corresponding to the microphone position.

[0071] Specifically, the screen driver module can rotate the screen by a preset angle for each rotation, for example, rotating by an angle of 60° for each rotation.

[0072] In the above technical solution, this utility model transmits a positioning signal from the signal transmitting module in the microphone to the signal receiving and processing module in the speaker body. The signal receiving and processing module then determines the position of the microphone relative to the speaker body based on the positioning signal and generates a corresponding screen driving signal. The screen driving module responds to the screen driving signal by rotating the screen to a target position corresponding to the microphone's position. Thus, when the singer moves in an open area or when people in different locations sing, the screen can rotate with the singer, ensuring the screen faces the singer directly. This facilitates the singer's view of the screen and lyrics, enhancing user interaction and the overall singing experience.

[0073] In summary, the intelligent speaker system and the follow-up control method for the speaker screen provided by this utility model have the following beneficial effects: The microphone's signal transmitting module transmits a positioning signal to the signal receiving and processing module in the speaker body. The signal receiving and processing module then determines the microphone's position relative to the speaker body based on the positioning signal and generates a corresponding screen driving signal. The screen driving module responds to this signal by rotating the screen to the target position corresponding to the microphone's location. Thus, when the singer moves in an open area or when someone sings from a different location, the screen can rotate with the singer, ensuring the screen faces the singer directly. This makes it easier for the singer to see the screen and lyrics, enhancing user interaction and the overall singing experience.

[0074] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
