That is, the at least two loudspeakers of the loudspeaker array structure can form one or more concentric circle loudspeaker arrays. Through the concentric circle loudspeaker array, more audio data from different measurement directions can be provided, which can not only improve the accuracy of audio measurement to optimize the listening experience, but also acquire more audio data from different measurement directions at once, shorten the measurement time, and improve the measurement efficiency.

[0057] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0058] This disclosure provides a loudspeaker array structure. For example... Figures 1 to 4 As shown, the loudspeaker array structure 10 includes: a loudspeaker bracket 100, at least two connectors 200, and at least two loudspeakers 300;

[0059] At least two of the connectors 200 are connected to the speaker bracket 100 at intervals;

[0060] Each of the loudspeakers 300 is connected to a different connector 200 and is located on one or more concentric circles on the same plane; wherein at least two of the loudspeakers are spaced apart in the circumferential direction of the concentric circles.

[0061] In this embodiment of the disclosure, the speaker array structure is used to output audio data through each speaker, and can be applied to scenarios where audio data is measured.

[0062] Here, the head-related transfer function can be obtained by processing the measured audio data. This head-related transfer function brings people a more realistic and lifelike auditory experience in many fields such as virtual reality, audio rendering, interactive experience, audio positioning and navigation, remote communication, headphone sound enhancement, hearing research and car audio systems.

[0063] For example, in a scenario where audio data is measured, a measurement microphone can be used to collect audio data output sequentially from each speaker in a speaker array structure to obtain audio data from different measurement locations; then, the head-related transfer function can be obtained by processing the audio data from different measurement locations; finally, the head-related transfer function can be used to reconstruct spatial sound to enhance the user's immersion and interactive experience in virtual reality.

[0064] The speaker bracket described above is used to support at least two speakers. This speaker bracket can be formed by connecting multiple brackets. Each bracket can be used to support a speaker.

[0065] It should be noted that the speaker bracket may consist of a single support rod or multiple support rods. Therefore, when designing the speaker bracket, it is necessary to improve its rigidity and stability to ensure that the speaker can be safely and reliably suspended from the bracket without any potential hazards.

[0066] In this embodiment of the disclosure, such as Figures 1 to 4 As shown, during the acquisition of audio data using the measuring microphone, the speaker bracket 100 can be placed on the mesh floor A of the anechoic chamber. This helps to reduce noise interference during measurement.

[0067] The aforementioned connectors connect the speaker bracket and the speaker respectively, and are used to fix the speaker to the speaker bracket.

[0068] It should be noted that the connection between the connector and the speaker bracket can be either a fixed connection or a movable connection. Here, the movable connection between the connector and the speaker bracket allows for adjustment of the radius of the circle formed by multiple speakers.

[0069] Furthermore, the connection between the connector and the speaker can be either a fixed connection or a movable connection. Here, a movable connection between the connector and the speaker allows for adjustment of the speaker's pitch angle, thereby adjusting the direction of the speaker's output audio data and enabling the measuring microphone to better capture audio.

[0070] In this embodiment of the disclosure, the number of speakers can be equal to the number of connectors, and one speaker is connected to one connector.

[0071] It should be noted that each speaker can be connected to the end of the corresponding connector, which allows for better spatial distribution of speakers located at different connector ends.

[0072] In this embodiment, each speaker is located on a concentric circle on the same plane and is spaced apart along the circumference of the concentric circle. That is, the speakers in the speaker array structure can form a concentric circle speaker array. Here, the position of the speakers can be adjusted to form a concentric circle speaker array with an adjustable radius, or the position of the speakers can be fixed to form a concentric circle speaker array with a fixed radius.

[0073] It should be noted that if at least two speakers are located on multiple concentric circles in the same plane, then the speakers in the speaker array structure can form multiple concentric circle speaker arrays.

[0074] In this embodiment of the disclosure, the speakers are spaced apart in the circumferential direction of the concentric circles, which may include: the speakers are spaced apart in the entire circumferential direction of the concentric circles, that is, the speakers can form a whole circle; it may also include: the speakers are spaced apart in a part of the circumferential direction of the concentric circles, that is, the speakers no longer form a whole circle, but form a part of the circle.

[0075] For example, such as Figure 1As shown, the speaker array structure may include nine speakers. These nine speakers are spaced apart along the circumference of a concentric circle, and can be distributed at nine positions: 0°, -30°, 30°, 60°, 90°, 120°, 12°, 180°, and 210°. Thus, when the head of the subject is located at the center of the concentric circle, audio data output from the speakers positioned at the nine locations can be sequentially collected using a head-mounted measuring microphone.

[0076] Of course, the loudspeaker array structure may include 12 loudspeakers. These 12 loudspeakers are spaced apart and evenly distributed along the circumference of concentric circles, forming a complete circle.

[0077] It should be noted that when measuring audio data, the speaker array structure includes multiple speakers surrounding the head wearing the measurement microphone, and the distance from the head to each speaker is equal, which can improve the accuracy of audio acquisition.

[0078] In this embodiment of the disclosure, each speaker can be evenly distributed along the circumference of a concentric circle, and the output direction of each speaker outputting audio data can be set towards the center of the concentric circle, thus facilitating better acquisition of audio data.

[0079] It should be noted that the speakers in the speaker array structure can be the same type of speaker, in order to better unify the output audio data.

[0080] It is understood that in the speaker array structure of this disclosure, each speaker is connected to a different connector and located on one or more concentric circles on the same plane, with at least two speakers spaced apart along the circumference of the concentric circles. In other words, at least two speakers in the speaker array structure can form one or more concentric circle speaker arrays. These concentric circle speaker arrays can provide more audio data from different measurement orientations, which not only improves the accuracy of audio measurements to optimize the listening experience but also allows for the acquisition of more audio data from different measurement orientations at once, shortening measurement time and improving measurement efficiency.

[0081] Furthermore, the concentric circle speaker array disclosed herein enables the speaker array structure to be developed towards lightweight and miniaturized design, making it more convenient for measurement.

[0082] In some embodiments, such as Figures 1 to 4 As shown, each of the connectors 200 is fixedly connected to the speaker bracket 100; or,

[0083] Each of the connectors 200 is movably connected to the speaker bracket 100, and each connector can drive the corresponding speaker 300 to move in the direction of increasing or decreasing the radius of the concentric circles.

[0084] In this embodiment of the disclosure, when each connector is fixedly connected to the speaker bracket, the radius of the concentric circle formed by at least two speakers is fixed. Here, the connector can be formed by extending from the speaker bracket in a direction perpendicular to the speaker bracket. That is, the speaker bracket and the connector can be integrally formed and fixedly connected.

[0085] In this embodiment of the disclosure, such as Figure 4 As shown, each speaker can move simultaneously in the direction of increasing the radius of the concentric circles to form a first concentric circle B, and can also move simultaneously in the direction of decreasing the radius of the concentric circles to form a second concentric circle C.

[0086] In this way, during the adjustment of the radius of the concentric circles, each speaker can still be distributed along the circumference of the concentric circles.

[0087] For example, the radius of the concentric circles can be adjusted between 1 meter and 1.4 meters.

[0088] It is understood that the connection method between the connector and the speaker bracket can be flexibly configured in the embodiments of this disclosure. Furthermore, by using the connector to move the speaker in a direction that increases or decreases the radius, the radius can be adjusted, thereby enabling the speaker array structure to provide a wider range of measurement scenarios and making measurements more convenient.

[0089] In this embodiment, the movable connection method between the connector and the speaker bracket can be set according to the actual situation, as long as the connector can drive the speaker to move.

[0090] In some embodiments, such as Figure 1 and 2 As shown, the connector 200 includes a locking rod 201, and the speaker bracket 100 forms a limiting locking member 101;

[0091] The engagement positions of the limiting engagement member 101 and the engagement rod 201 are different, and the radii of the concentric circles formed by the speakers 300 connected to the engagement rod 201 are different.

[0092] In this embodiment of the present disclosure, the limiting engagement member can be fixed on the speaker bracket. The limiting engagement member can be used to engage different positions of the engagement rod, thereby changing the radius of the concentric circle formed by the speaker, that is, the radius of the concentric circle can be adjusted.

[0093] It should be noted that the limiting engagement component has a limiting engagement state and a disengaged engagement state. When the limiting engagement component is in the limiting engagement state, the limiting engagement component is fixedly connected to the engagement rod; when the limiting engagement component is in the disengaged engagement state, the limiting engagement component is separated from the engagement rod; in this way, the engagement position can be flexibly adjusted.

[0094] It is understood that the position of the speaker can be changed by setting different engagement positions of the limiting engagement member and the engagement rod, thereby realizing the adjustment of the radius of the concentric circle.

[0095] In some embodiments, such as Figure 1 and 3 As shown, the connector 200 includes a telescopic rod 202;

[0096] The fixing part of the telescopic rod 202 is fixed to the speaker bracket 100;

[0097] The free part of the telescopic rod 202 is connected to the speaker 300 and can drive the speaker 300 to move when it moves relative to the fixed part.

[0098] In this embodiment, the free part can move relative to the fixed part in a direction toward the center of the circle or in a direction away from the center of the circle, thereby realizing the extension and retraction of the telescopic rod.

[0099] Here, when the free part moves toward the center of the circle, the free part can drive the speaker to move in the direction of reducing the radius, thus realizing the reduction of the radius;

[0100] When the free part moves in a direction away from the center, it can drive the speaker to move in a direction away from the radius, thus increasing the radius.

[0101] It should be noted that the free part is movably connected to the fixed part. In some embodiments, the free part may be disposed on the fixed part and movable relative to the fixed part. In other embodiments, the free part may be sleeved outside the fixed part and movable relative to the fixed part.

[0102] It is understood that the radius of adjustment can be flexibly adjusted by changing the position of the free part of the telescopic rod, that is, by changing the telescopic length of the telescopic rod.

[0103] In some embodiments, such as Figure 1 and Figure 4 As shown, the speaker array structure further includes:

[0104] Adjustment component 400, connected to connector 200 and speaker 300, is used to adjust the pitch angle of speaker 300.

[0105] In this embodiment of the disclosure, the adjustment component is used to adjust the pitch angle of the loudspeaker so that the output direction of the audio data output by each loudspeaker is towards the center of the circle.

[0106] For example, such as Figure 1As shown, when the speaker bracket 100 is fixedly connected to the connector 200, the pitch angle of the speaker 300 can be adjusted by the adjustment piece 400 so that the output direction of the audio data output by each speaker 300 is towards the center of the circle.

[0107] Of course, when the speaker bracket 100 is movably connected to the connector 200, the pitch angle of the speaker 300 can also be adjusted by the adjustment piece 400 so that the output direction of the audio data output by each speaker 300 is towards the center.

[0108] In this embodiment of the disclosure, such as Figure 1 As shown, the adjusting member 400 can be fixed to the end of the connector 200 and connected to the bottom surface of the speaker 300. Here, the adjusting member can be fixed to the end of the connector by screws.

[0109] It should be noted that the adjusting component may include a movable component that moves relative to the connecting component, thereby moving the speaker to adjust the speaker's pitch angle. Alternatively, the adjusting component may include an adjusting component with a locking part, which engages speakers in different positions to adjust the speaker's pitch angle.

[0110] In this embodiment, the pitch angle of the speaker varies depending on the angle between the bottom surface of the speaker and the connector. Here, the bottom surface of the speaker can be perpendicular to the connector, or the angle between them can be acute or obtuse.

[0111] Understandably, by adjusting the pitch angle of the loudspeakers, multiple loudspeakers in the loudspeaker array structure can be aimed at the head of the object being measured to collect audio data, making the measurement more convenient and shortening the measurement time.

[0112] In some embodiments, such as Figure 4 As shown, the speaker bracket includes:

[0113] A first bracket 102 and a second bracket 103 are arranged along a first direction;

[0114] A third bracket 104 is disposed along the second direction and connected to the first bracket 102 and the second bracket 103;

[0115] The first bracket 102, the second bracket 103 and the third bracket 104 are all connected to a plurality of the speakers 300.

[0116] In this embodiment of the disclosure, the first direction and the second direction can be two mutually perpendicular directions. The first direction can be a direction perpendicular to the ground, and the second direction can be a direction parallel to the ground.

[0117] It should be noted that a stable speaker bracket can be formed by connecting the first, second, and third brackets. Of course, the speaker bracket may also include a fourth bracket, which is connected to the first and second brackets and is positioned opposite and parallel to the third bracket.

[0118] Here, the fourth bracket makes the speaker support more stable. Furthermore, the four brackets can form a square support, allowing multiple speakers connected to the four brackets to be distributed circumferentially, thus enabling better surround of the test object during testing and allowing for the measurement of omnidirectional audio data.

[0119] In this embodiment, the first bracket, the second bracket, and the third bracket are all connected to multiple speakers. That is, by distributing multiple speakers evenly across the three brackets, the speakers can be distributed more uniformly, enabling better multi-directional audio data delivery.

[0120] In some embodiments, such as Figure 4 As shown, the number of speakers 300 connected to the first bracket 102, the second bracket 103, and the third bracket 104 is the same;

[0121] And / or,

[0122] The multiple speakers 300 connected to the same bracket in the first bracket 102, the second bracket 103 and the third bracket 104 are evenly distributed;

[0123] And / or,

[0124] The angle between the line connecting two adjacent speakers 300 connected to the same bracket and the center of the concentric circle, and the angle between the line connecting two adjacent speakers 300 connected to adjacent brackets and the center of the circle, are both first preset angles.

[0125] In this embodiment, the first bracket, the second bracket, and the third bracket are connected to the same number of speakers. Alternatively, each of the three brackets may be configured to connect to three or more speakers.

[0126] In this embodiment of the disclosure, the multiple speakers connected to the same bracket are evenly distributed, which may include: the included angle between the lines connecting two adjacent speakers to the center of the circle in the same bracket are all equal, that is, the multiple speakers connected to the same bracket are evenly distributed along the circumference.

[0127] In this embodiment of the disclosure, the adjacent support includes two supports that are connected and adjacent to each other, for example, a first support and a third support that are connected and adjacent to each other; or, a second support and a third support that are connected and adjacent to each other.

[0128] It should be noted that the multiple speakers on the first bracket and the multiple speakers on the second bracket can be symmetrically distributed around the center of a circle.

[0129] In this embodiment of the disclosure, the smaller the first preset angle, the more speakers are arranged in the speaker array structure, and the more directional audio data the speaker array structure can provide. In some embodiments, the first preset angle is in the range of 2.5 degrees to 30 degrees.

[0130] For example, such as Figures 1 to 4 As shown, the speaker array structure contains nine speakers 300, and the first preset angle can be set to 30 degrees.

[0131] It is understood that the angle between the line connecting two adjacent speakers connected to the same bracket and the center of the concentric circle, and the angle between the line connecting two adjacent speakers connected to adjacent brackets and the center of the circle, are both first preset angles. That is to say, in the embodiments of this disclosure, when multiple speakers connected to the same bracket are evenly distributed along the circumference, two adjacent speakers connected to adjacent brackets can also be evenly distributed along the circumference, just as multiple speakers connected to the same bracket can be evenly distributed along the circumference.

[0132] In some embodiments, such as Figure 4 and Figure 5 As shown, the third bracket 104 is connected between the first end of the first bracket 102 and the first end of the second bracket 103;

[0133] The second end of the first bracket 102 and the second end of the second bracket 103 are both connected to a first movable caster 105 and / or a first support foot 106.

[0134] In this embodiment of the disclosure, both the number of first movable casters connected to the first bracket and the number of first movable casters connected to the second bracket can be multiple. Similarly, both the number of first supporting feet connected to the first bracket and the number of first supporting feet connected to the second bracket can also be multiple.

[0135] Here, the multiple first movable casters and first supporting feet can be evenly distributed to provide better mobility and stability.

[0136] It should be noted that the number of first swivel casters connected to the first bracket can be the same as the number of first swivel casters connected to the second bracket. For example, the number of first swivel casters connected to the first bracket and the number of first swivel casters connected to the second bracket can both be 2, 3, or 4, etc.

[0137] Of course, the number of first supporting feet connected to the first bracket can be the same as the number of first supporting feet connected to the second bracket. For example, the number of first supporting feet connected to the first bracket and the number of first supporting feet connected to the second bracket can both be 2, 3, or 4, etc.

[0138] In this embodiment of the present disclosure, the first supporting foot can be configured as a telescopic foot. When it is necessary to move the speaker bracket, the length of the foot can be shortened to facilitate movement; when it is necessary to fix the speaker bracket, the length of the foot can be extended to fix the speaker bracket.

[0139] It should be noted that the weight that the first support foot can support is positively correlated with the number of speakers; the more speakers there are, the greater the weight that the first support foot can support.

[0140] For example, such as Figures 1 to 4 As shown, the first support foot needs to support 9 speakers, and a single speaker can weigh up to 3.2kg, so the weight that the first support foot can support can reach 30kg.

[0141] It is understood that by providing a first movable caster and a first supporting foot, the speaker array structure can be moved and fixed more easily.

[0142] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the first bracket 102, the second bracket 103 and the third bracket 104 each include a plurality of bracket rods 107;

[0143] Each of the speaker 300 is connected to one of the bracket rods 107.

[0144] In this embodiment, multiple support rods can be spaced apart along the same direction. To make the first, second, and third supports more stable, crossbars perpendicular to the support rods can also be provided. The support rods and crossbars are arranged perpendicularly.

[0145] For example, such as Figure 6 As shown, the multiple support rods 107 can be two support rods 107 arranged in parallel with each other.

[0146] Understandably, by setting multiple support rods, the speaker bracket can more stably support multiple speakers, and the object under test and multiple speakers can be better positioned on the same plane, which facilitates the improvement of measurement accuracy.

[0147] This disclosure also proposes a loudspeaker device, such as... Figures 1 to 4 As shown, the loudspeaker device includes:

[0148] The speaker array structure 10 as described in one or more of the above embodiments;

[0149] The seat structure 20 is disposed within the space enclosed by the speaker array structure 10.

[0150] In this embodiment, the seat structure is used for a test subject to sit on. The position of the seat structure can be adjusted so that the head of the test subject sitting on the seat structure is on the same plane as at least two speakers. Furthermore, the head of the test subject can be positioned at the center of the concentric circles formed by the speakers. In this way, the measuring microphone worn on the test subject's head can better acquire the audio data output by the speakers.

[0151] It should be noted that, since different test subjects will sit on the seat structure, the seat structure can be set to bear a weight greater than 100 kg.

[0152] Understandably, the loudspeaker device includes a loudspeaker array structure that can provide audio data from more different measurement directions at the same measurement distance. This not only improves the accuracy of audio measurement to optimize the audio experience, but also allows for the acquisition of more audio data from different measurement directions at once, shortening measurement time and improving measurement efficiency.

[0153] In some embodiments, such as Figure 4 , Figure 7 and Figure 8 As shown, the seat structure 20 includes:

[0154] Rotating platform 21;

[0155] The seat body 22 is movably mounted on the rotating platform 21 and can rotate with the rotating platform 21;

[0156] In the speaker array structure, at least two speakers 300 are used to output audio data sequentially after the rotating platform 21 rotates by a second preset angle.

[0157] In this embodiment of the present disclosure, the seat body can be embedded in the rotating platform and can move relative to the rotating platform.

[0158] The aforementioned rotating platform is capable of rotation. The center of rotation of the rotating platform can coincide with the head of the test subject sitting on the seat body.

[0159] In this embodiment of the disclosure, the rotating platform may include a rotating disk and a rotating part, the rotating part being capable of driving the rotating disk to rotate. Here, the rotating disk can rotate a maximum of 360 degrees, and also a maximum of 180 degrees.

[0160] It should be noted that by writing code, the rotating part can drive the rotating disk to rotate by a second preset angle each time.

[0161] Here, the second preset angle can be set between 1 degree and 10 degrees. For example, the rotating disk can be controlled to rotate 5 degrees each time.

[0162] In this embodiment, the rotating part may include a drive motor, which can be controlled by a remote control to drive the rotating disk to rotate a second preset angle each time. Here, the remote control can be used to remotely control the drive motor via infrared, and this embodiment does not limit this.

[0163] It should be noted that before controlling the speaker array structure to output audio data, the subject wearing the measuring microphone should first sit on the seat. When collecting audio data using the measuring microphone, multiple speakers can be controlled to output audio data sequentially, corresponding to one acquisition result from the measuring microphone; then the rotating platform can be rotated to a second preset angle, and multiple speakers can be controlled to output audio data sequentially, corresponding to another acquisition result from the measuring microphone; then the rotating platform can be rotated to a second preset angle again, and multiple speakers can be controlled to output audio data sequentially, corresponding to another acquisition result from the measuring microphone; and so on, until the rotating platform has rotated 180 degrees. In this way, the measuring microphone can obtain multiple acquisition results corresponding to multiple rotation directions.

[0164] Understandably, if the speakers in the speaker array structure are positioned at nine horizontal angles (0°, -30°, 30°, 60°, 90°, 120°, 150°, 180°, and 210°), then each acquisition result will include audio data from all nine angles. In this way, a more accurate head-related transfer function can be obtained from the audio data from these nine angles in each acquisition result for spatial sound reconstruction.

[0165] In some embodiments, such as Figure 4 , Figure 7 and Figure 8 As shown, the seat structure also includes:

[0166] The headrest 23 is used for the head of the test subject sitting on the seat body 22 to rest against;

[0167] Support rod 24 is fixed to the back of seat body 22 in the rotating platform 21;

[0168] Adjustment plate 25, connecting the headrest 23 and the support rod 24, is used to adjust the distance between the headrest 23 and the seat body 22;

[0169] The seat body 22 is movable in a direction away from or towards the support rod 24; and / or, is movable in a direction away from or towards the rotating platform.

[0170] The aforementioned support rod and headrest are used to stabilize the subject's head by allowing them to sit upright while resting their head on the support and headrest.

[0171] In this embodiment, one end of the adjustment plate can be fixedly connected to the headrest, and the other end of the adjustment plate can be connected to different positions of the support rod.

[0172] It should be noted that the distance from the headrest to the seat body varies depending on the connection position between the adjustment plate and the support rod. In other words, the headrest height can be adjusted up and down along the extension direction of the support rod in this embodiment.

[0173] In this embodiment of the disclosure, the seat body is movably disposed on the rotating platform and is capable of moving away from or towards the support rod; and / or, capable of moving away from or towards the rotating platform. That is, the position of the seat body can be adjusted forward and backward relative to the support rod, and its height can also be adjusted relative to the rotating platform.

[0174] Here, because the height of the test subjects varies, in order to ensure that the heads of different test subjects are at a fixed height, the height of the seat needs to be adjusted to accommodate test subjects of different heights.

[0175] It should be noted that the maximum height adjustment of the seat body relative to the rotating platform can be set within the range of 10cm to 15cm.

[0176] It is understood that, by setting an adjustment plate to connect the headrest and the support rod, and by movably setting the seat body on the rotating platform, this embodiment can not only adjust the distance between the headrest and the seat body, but also adjust the seat body back and forth relative to the support rod and adjust the height of the seat body relative to the rotating platform, thereby enabling the seat structure to better adapt to test subjects of different heights and / or body shapes.

[0177] In some embodiments, such as Figure 4 , Figure 7 and Figure 8 As shown, the seat structure 20 further includes:

[0178] The second support foot 26 is located on the side of the rotating platform 21 away from the seat body 22, and is used to support the rotating platform 21;

[0179] The second movable caster 27 is connected to the same side of the rotating platform 21 as the supporting foot 26, and is used to drive the rotating platform 21 to move.

[0180] In this embodiment, the rotating platform further includes a fixed platform for supporting the rotating part, which can be disposed between the fixed platform and the rotating disk. The second support foot can be connected to the fixed platform to achieve stable support.

[0181] It should be noted that there may be multiple second support feet, which may be evenly and spaced out on the side of the rotating platform away from the seat body.

[0182] In this embodiment of the disclosure, there may be multiple second movable casters, which may be evenly and spaced out on the side of the rotating platform away from the seat body.

[0183] It should be noted that the second support foot can be set as a telescopic foot. When it is necessary to move the seat structure, the length of the foot can be shortened to facilitate movement; when it is necessary to fix the seat structure, the length of the foot can be extended to fix the seat structure.

[0184] It is understood that the embodiments of this disclosure, by providing a second supporting foot and a second movable caster, enable the seat structure to be easily moved and fixed.

[0185] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
