Description

Technical Field

[0001] The utility model relates to a control component of a mixing console, in particular to a direct drive type potentiometer regulator and a mixing console. Background Art

[0002] In control devices such as mixing consoles, a slide (type) potentiometer is usually used to control signals. In order to achieve fast switching between different modes and extend the service life of the slide potentiometer, a motor-driven slide potentiometer is generally adopted. For this type of slide potentiometer, the motor can drive the belt transmission mechanism to move, and then the belt drives the push rod to move so that the push rod moves to the required position.

[0003] However, there are certain defects in controlling the movement of the push rod by means of belt transmission. On the one hand, being installed too loose or too tight, or the belt becoming loose due to wear after a period of use, as well as the vibration generated by the motor, will all affect the accuracy of the linear potentiometer and result in poor use stability.

[0004] On the other hand, a slide potentiometer usually requires a brush to cooperate with a resistor body to determine the position of the push rod and control the signal. The resistor body and the brush are prone to poor contact after wear, affecting the reliability of use.

[0048] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0049] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0050] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0051] like Figures 1 to 4 As shown, a direct-drive potentiometer regulator (or direct-slide potentiometer or direct-slide electric fader, etc.) corresponding to a preferred embodiment of the utility model includes a housing component 1, a push rod 2, a magnetic circuit component 3 and a mover component 4.

[0052] The housing assembly 1 is provided with a receiving cavity 10. The housing assembly 1 can be formed by connecting two or more housings. For example, it can be made of materials such as metal or plastic.

[0053] Part of the push rod 2 is exposed outside the housing assembly 1 for easy operation and can move linearly relative to the housing assembly 1. For example, in some embodiments, the volume can be adjusted by moving the push rod 2.

[0054] The magnetic circuit assembly 3 is arranged in the receiving cavity 10 and extends along the moving direction of the push rod 2.

[0055] The mover assembly 4 is arranged in the receiving cavity 10 and includes a coil 40 sleeved on the mover assembly 4. The push rod 2 is connected to the mover assembly 4. The magnetic circuit assembly 3 includes an outer magnetic pole adjacent to the coil 40, and the polarity of the outer magnetic pole of the magnetic circuit assembly 3 adjacent to the coil 40 is the same, so that the magnetic induction lines generated by the outer magnetic pole can all pass through the coil 40 from the outside to the inside or from the inside to the outside. After the coil 40 is energized, the energized coil 40 is acted on by the Ampere force in the magnetic field, driving the mover assembly 4 and the push rod 2 connected thereto to move relative to the housing assembly 1 along the magnetic circuit assembly 3. When the direction of the current flowing into the coil 40 is changed, the direction of the magnetic force received by the mover assembly 4 is opposite, thereby realizing the reciprocating movement of the push rod 2. When the power is cut off, the mover assembly 4 will stop moving under the action of the frictional resistance.

[0056] By using the magnetic drive method to realize the movement of the mover assembly 4, there is no need to use drive methods such as motors and belt drives. Therefore, when the direct drive type potentiometer works, the vibration is smaller, and there will be no poor contact caused by the wear of the resistor body and the brush, and its working stability is better.

[0057] In some embodiments, the magnetic circuit assembly 3 includes at least one set of magnet groups 33. The magnet group 33 includes two magnets 30 arranged radially along the magnetic circuit assembly 3, and the two magnets 30 are magnetized along their arrangement direction. Specifically, as Figure 2 、 Figure 4 and Figure 5 shown, the magnetic circuit assembly 3 includes one set of magnet groups 33. The magnet 30 is strip-shaped and extends along the moving direction of the push rod 2. Each magnet 30 includes two magnetic poles (N pole and S pole), and the polarities of the adjacent magnetic poles of the two magnets 30 are the same, and the polarities of the two opposite magnetic poles are opposite; the magnet 30 can select a suitable size according to the distance that the push rod 2 needs to move.

[0058] In other embodiments, the magnetic circuit assembly 3 includes a plurality of magnet groups 33 arranged along the moving direction of the push rod 2, and the user can increase or decrease the number of magnet groups 33 according to the required length; optionally, as Figure 6 shown, two adjacent magnets 30 are attached to each other, or, as Figure 7As shown, a spacer 31 is provided between two adjacent magnets 30 on the same side. The spacer 31 can be made of a magnetic material or a non-magnetic material, which can reduce the repulsive force between the two magnets.

[0059] As Figure 4 , Figure 6 and Figure 7 shown, the direct drive potential regulator further includes a magnetic conductive member 32 between two magnets 30 of the magnet group 33. The magnetic conductive member 32 is strip-shaped and extends along the moving direction of the push rod 2; the two magnets 30 of the magnet group 33 are respectively connected to two opposite surfaces of the magnetic conductive member 32. The magnetic conductive member 32 can improve the magnetic field utilization efficiency and facilitate the firm connection of the magnets 30 on both sides thereof. When the magnetic circuit assembly 3 includes a plurality of magnet groups 33 arranged along the moving direction of the push rod 2, a plurality of magnet groups 33 can be connected by one magnetic conductive member 32.

[0060] Optionally, Figure 4 in the embodiment shown, the two magnets 30 symmetrically arranged on both sides of the magnetic conductive member 32 can enable the mover assembly 4 to receive a uniform thrust from the magnetic circuit assembly 3.

[0061] In some embodiments, as Figures 8 to 9 shown, the magnetic circuit assembly 3 includes a plurality of magnet groups 33. Each magnet group 33 includes two magnets 30 arranged radially along the magnetic circuit assembly 3. The arrangement directions of the two magnets 30 of each magnet group 33 are different. The arrangement directions of the magnets 30 of each magnet group 33 are shown by dashed lines with arrows in the figure. The magnets 30 are magnetized along the arrangement directions of the two magnets 30 of the magnet group 33 where they are located.

[0062] Furthermore, the magnetic circuit assembly 3 further includes a magnetic conductive member 32, and the two magnets 30 of each magnet group 33 are both connected to the magnetic conductive member 32.

[0063] In some embodiments, as Figure 8 shown, the cross-section of the magnetic conductive member 32 perpendicular to the moving direction of the push rod 2 is rectangular. In the same cross-section, the magnetic circuit assembly 3 includes two magnet groups 33, which are symmetrically arranged around the magnetic conductive member 32.

[0064] In other embodiments, as Figure 9 shown, the cross-section of the magnetic conductive member 32 perpendicular to the moving direction of the push rod 2 is hexagonal. In the same cross-section, the magnetic circuit assembly 3 includes three magnet groups 33, which are symmetrically arranged around the magnetic conductive member 32.

[0065] It can be understood that the number of magnet groups 33 can be determined according to the actual situation. Multiple magnet groups 33 can increase the number of magnetic induction lines passing through the coil 40, enhance the driving force, and thus improve the sensitivity.

[0066] In some embodiments, such as Figure 10 and Figure 11 shown, the magnetic circuit assembly 3 includes a magnet 30 with a circular outer contour of the cross-section. The polarities of the outer magnetic poles on the outer side of the magnet 30 are the same. Figure 10 The approximate demarcation line between the two magnetic poles is shown by a dashed line in Figure 10 In the embodiment shown, the magnet 30 is solid; Figure 11 In the embodiment shown, the magnet 30 is annular, provided with a central hole 300, and a magnetic conductor 32 or no magnetic conductor 32 is arranged in the central hole 300.

[0067] It can be understood that in some embodiments, the outer contour of the cross-section of the magnet 30 can also be polygonal. For example, as shown in Figure 12 and Figure 13 shown, rectangular or square.

[0068] The coil 40 can be set to have the same shape as the outer contour of the magnet 30. Due to the annular structure of the outer magnetic poles, more magnetic induction lines passing through the coil 40 can be provided, further improving the driving force and sensitivity.

[0069] Such as Figure 4 shown, the housing assembly 1 includes a top plate 110 and a bottom plate 120 arranged opposite to each other. The top plate 110 is provided with a sliding groove 112 extending along the movement direction of the push rod 2. The push rod 2 is arranged in the sliding groove 112 and exposed from the sliding groove 112 into the housing assembly 1 for easy manipulation.

[0070] Further, as shown in Figure 2 and Figure 4 shown, the housing assembly 1 includes a first housing 11 and a second housing 12. The first housing 11 includes a top plate 110, a side shell 111 connected to the top plate 110, and a sliding groove 112; the second housing 12 includes a bottom plate 120 and side plates 121 arranged on both sides of the bottom plate 120 and parallel to the movement direction of the push rod 2; the magnetic circuit assembly 3 is arranged in the receiving cavity 10 formed by the first housing 11 and the second housing 12 and is relatively fixed to the bottom plate 120.

[0071] Such as Figure 2 shown, the direct drive type potential regulator further includes a support member 34 connected between the magnetic circuit assembly 3 and the bottom plate 120. The support member 34 is arranged at both ends of the magnetic circuit assembly 3 along the movement direction of the push rod 2, and can suspend the magnetic circuit assembly 3 so that it does not contact the inner wall of the housing assembly 1.

[0072] Such as Figure 2 , Figure 4 and Figure 14As shown, the mover assembly 4 includes a sleeve 41 sleeved on the magnetic circuit assembly 3. The sleeve 41 is connected to the push rod 2, and the coil 40 is wound around the sleeve 41. By providing the sleeve 41, on the one hand, it facilitates the connection between the mover assembly 4 and the push rod 2. On the other hand, it can prevent the coil 40 from directly rubbing against the magnetic circuit assembly 3 and being damaged, thereby increasing the service life.

[0073] In some embodiments, the mover assembly 4 is supported by the bottom plate 120 of the first housing 11 and does not contact the magnetic circuit assembly 3. Lubricating oil can be provided between the mover assembly 4 and the bottom plate 120 to reduce wear, and a damping can be formed between the mover assembly 4 and the magnetic circuit assembly 3. After the coil 40 stops being energized, the mover assembly 4 can stop quickly. In other embodiments, the mover assembly 4 is spaced from the first housing 11 and the second housing 12 and does not contact the first housing 11 and the second housing 12 to reduce the obstruction of the first housing 11 and the second housing 12 to the movement of the mover assembly 4. The mover assembly 4 is supported by the magnetic circuit assembly 3. Lubricating oil can be provided between the sleeve 41 and the magnetic circuit assembly 3 to reduce wear, and a damping can be formed between the sleeve 41 and the magnetic circuit assembly 3. After the coil 40 stops being energized, the mover assembly 4 can stop quickly.

[0074] The mover assembly 4 includes a connecting plate 42 connected between the push rod 2 and the sleeve 41. The connecting plate 42 is provided with an input interface 420 and an output interface 421. The direct drive potentiometer further includes a control circuit module (not shown in the figure) electrically connected to the input interface 420, the output interface 421, and the coil 40. The control circuit module is electrically connected to the input interface 420 and the output interface 421 at the same time. The input interface 420 is used to input current to energize the coil 30, and the output interface 421 is used to realize data exchange (communication) between the control circuit module and an external circuit. It can be understood that the control circuit module may further include a chip and peripheral circuits for calculating and processing signals. Optionally, the control circuit module is integrally disposed on the connecting plate 42, and the connecting plate 42 is a circuit board (such as a PCB circuit board) with corresponding circuits disposed thereon.

[0075] The control circuit module can receive an external operation signal and pass a direct current in a corresponding direction through the coil 40 according to the operation signal. By controlling the direction of the current passing through the coil 40, the moving direction of the push rod 2 can be controlled. By controlling the magnitude and time of the current passing through the coil 40, the moving distance of the coil 40 can be controlled, so that the push rod 2 can be moved to a required position.

[0076] The direct drive potentiometer also has the function of identifying the position of the mover assembly 4. After the push rod 2 is manually pushed to move, it can detect the position of the mover assembly 4, so as to adjust an audio signal or other signals.

[0077] The control circuit module can calculate the position information of the mover assembly 4 based on the energization condition of the coil 40. The energization condition includes the energization time, as well as the magnitude and direction of the current. Specifically, according to the energization time, as well as the magnitude and direction of the current, the moving distance of the push rod 2 can be calculated. Combining with the initial coordinates of the push rod 2, the position coordinates of the push rod 2 after movement can be obtained.

[0078] In some embodiments, the direct drive type potential regulator includes a distance sensor or a position sensor, and the current position of the mover assembly 4 is detected by the distance sensor and the position sensor. In other embodiments, the control circuit module energizes the coil 40 with alternating current, and determines the position of the coil 40 by measuring the inductive reactance generated by the coil 40. It can be understood that when the coil 40 is energized with alternating current, it will generate an alternating magnetic field. The external magnetic conductive object will generate an induced magnetic field under the influence of the magnetic field, which in turn affects the magnetic field of the coil 40. Different magnetic conductive properties of the external environment of the coil 40 will affect the inductive reactance of the coil 40. By controlling the magnetic conductive properties of each part of the housing assembly 1 outside the coil 40 along the length direction of the magnetic circuit assembly 3, the inductive reactance generated by the coil 40 at different positions can be made different, so as to determine the position of the coil 40 according to the magnitude of the inductive reactance.

[0079] In some embodiments, the housing assembly 1 includes a plurality of positioning holes 1200 arranged opposite to the magnetic circuit assembly 3. The plurality of positioning holes 1200 are arranged along the moving direction of the push rod 2. At least the part of the housing assembly 1 where the positioning holes 1200 are opened is made of a magnetic conductive material. By changing the size of the positioning holes 1200, the magnetic conductive properties of different positions of the housing assembly 1 can be changed, so as to change the inductive reactance of the coil 40 at different positions, and further the position where the push rod 2 is located can be determined according to the magnitude of the inductive reactance. Optionally, as Figure 15 shown, the positioning holes 1200 are all arranged on the bottom plate 120. At this time, only the bottom plate 120 or the second housing 12 of the housing assembly 1 can be made of a magnetic conductive material, or all can be made of a magnetic conductive material. Further optionally, the width B1 of the plurality of positioning holes 1200 remains unchanged, and only the length L1 changes, so as to improve the accuracy and precision of position detection.

[0080] In another embodiment, as Figure 16As shown in the figure, the housing assembly 1 includes a plurality of positioning pieces 1201 disposed opposite to the magnetic circuit assembly 3. The plurality of positioning pieces 1201 are made of a magnetic conductive material and are arranged along the moving direction of the push rod 2. By changing the dimensions (such as length, width, and thickness, etc.) of the positioning pieces 1201, the inductive reactance of the coil 40 at different positions is changed, so as to determine the position of the push rod 2. Optionally, the positioning pieces 1201 are all disposed on the surface of the bottom plate 120 facing the magnetic circuit assembly 3. Further optionally, the width B2 and length L2 of the positioning pieces 1201 remain unchanged, only the thickness changes, or the width B2 and thickness of the positioning pieces 1201 remain unchanged, only the length L2 changes.

[0081] The inductive reactance of the coil 40 when the push rod 2 is at different positions can be measured in advance, and the inductive reactance data and the position information of the push rod 2 corresponding to the inductive reactance data are recorded in the control circuit module. When the inductive reactance data is detected, the control circuit module can determine the position of the push rod 2 according to the stored data.

[0082] In some usage scenarios, before controlling the movement of the push rod 2, an alternating current is applied to the coil 40 to determine the initial position of the push rod 2, which is recorded in the control circuit module; subsequently, the control circuit module outputs a control signal to apply a direct current to the coil 40, and the direction of the direct current can be determined according to specific circumstances; after applying the direct current, driven by the mover assembly 4, the push rod 2 moves along the direction of the chute 112, and the control circuit module can calculate the position of the push rod 2 according to the initial position information of the push rod 2 and the movement information of the push rod 2 after applying the direct current (i.e., the movement direction and the time of applying the current); or, an alternating current is applied to the coil 40 again to obtain the position information of the push rod 2, and external devices (such as audio equipment) can be adjusted according to the position information of the push rod 2.

[0083] In some other usage scenarios, the push rod 2 is manually pushed, an alternating current is applied to the coil 40, and the inductive reactance generated by the coil 40 is detected, so that the position information of the push rod 2 can be calculated, and external devices (such as audio equipment) can be adjusted according to the position information of the push rod 2.

[0084] Optionally, the magnitude of the alternating current is less than the magnitude of the direct current, so that the coil 40 will not move left and right when the alternating current is applied. Further optionally, the magnitude of the force that drives the coil 40 to move when the alternating current is applied to the coil 40 is not greater than the magnitude of the frictional force received by the mover assembly 4.

[0085] The present utility model also provides a mixing console, which includes the direct drive type potentiometer regulator as described above. The mixing console can control the audio signals of audio equipment, such as increasing or decreasing the signals.

[0086] The above is only the specific implementation manner of the present utility model, and any improvement made on the premise of the conception of the present utility model shall be regarded as the protection scope of the present utility model.
