Description

Technical Field

[0001] This application relates to the field of intelligent control technology, and in particular to a control structure and a Bluetooth headset. Background Technology

[0002] Headphones are audio playback devices that fit close to the ears. They receive electrical signals from media players or signal receivers and convert them into clearly discernible sound waves through built-in miniature speakers. Over time, their technology and design have evolved from the initial wired headphones to today's wireless Bluetooth headphones. Modern Bluetooth headphones, leveraging advanced wireless communication technology, have freed users from the constraints of traditional wired headphones, giving them greater freedom and convenience when enjoying music and audio content. This innovation not only enhances the user experience but also drives the audio equipment industry towards greater intelligence and convenience.

[0003] In actual use, although existing Bluetooth headphones have a variety of functions, users are prone to accidental touches when using gesture control. For example, when switching tracks or adjusting the volume, other functions are often accidentally triggered, causing inconvenience to the user. Utility Model Content

[0004] This application provides a control structure and a Bluetooth headset to solve the problem that existing Bluetooth headsets are prone to accidental touches during gesture control, which often triggers other functions unintentionally and causes inconvenience to users.

[0005] In a first aspect, embodiments of this application provide a control structure applied to a Bluetooth headset, comprising: The housing has a mounting groove. Multiple first sensors, each of which is used to detect airflow; Control unit, which is electrically connected to the first sensor; An isolator is disposed in the mounting groove to isolate two adjacent first sensors to prevent crosstalk of airflow signals received by each first sensor.

[0006] Optionally, the control structure further includes a second sensor located in the middle of the mounting slot. The second sensor is used to detect control gestures. The control unit is electrically connected to the second sensor. After the second sensor detects a control gesture, the first sensor can detect airflow so that the control unit controls the Bluetooth headset to execute function commands.

[0007] Optionally, the isolation component includes multiple barrier plates, both ends of which have gaps with the housing, and an airflow channel is formed between two adjacent barrier plates, with each of the first sensors placed separately in one of the airflow channels.

[0008] Optionally, the isolation element includes multiple barrier plates, which divide the mounting groove into multiple independent chambers, with each of the first sensors placed separately in one of the chambers.

[0009] Optionally, each of the isolation components is integrally formed with the housing, or the isolation components are detachable from the housing.

[0010] Optionally, the second sensor is an airflow sensor, and the first sensor is a millimeter-wave sensor.

[0011] Optionally, the periphery of the mounting groove is covered with a protective element, which is a mesh structure.

[0012] This application also proposes a Bluetooth headset, including a control structure and a control center, wherein the control center is electrically connected to the control unit and is used for Bluetooth communication with electronic devices.

[0013] Optionally, the control structure has four first sensors, the isolation component includes four barrier plates, an airflow channel is provided between two adjacent barrier plates, and each first sensor is accommodated within an airflow channel; when the Bluetooth headset is worn, two of the airflow channels are arranged perpendicularly, and the other two airflow channels are arranged horizontally.

[0014] Optionally, the Bluetooth headset includes an earbud connected to the housing, the earbud being located at the end of the housing away from the mounting slot.

[0015] The technical solutions provided in this application have the following advantages compared with the prior art: The control structure of this application enables precise gesture control of Bluetooth headsets, including track switching, pausing, and volume adjustment, by placing isolation components between multiple first sensors. Specifically, the Bluetooth headset housing has a mounting slot containing multiple first sensors for detecting airflow. Isolation components are placed between adjacent first sensors to effectively prevent interference between sensors in different locations, thus avoiding interference with electrical signal commands. The control unit is electrically connected to the first sensors. When a first sensor detects airflow, it converts the airflow direction into an electrical signal and transmits it to the control unit, thereby executing the corresponding function command. For example, when a user plays music and switches tracks using a specific gesture (such as sliding their hand to the left on the mounting slot), one of the first sensors detects the airflow generated by the hand movement and transmits the signal to the control unit to execute the track switching command, effectively avoiding crosstalk issues caused by airflow signals received by the first sensors.

[0024] To address the problem that existing Bluetooth headsets 200 are prone to accidental touches during gesture control, often triggering other functions unintentionally and causing inconvenience, this application provides a control structure 100 that uses a combination of multiple first sensors 2 and multiple isolators 11 to achieve precise gesture control of the Bluetooth headset 200 for functions such as track switching, pausing, and volume adjustment.

[0025] Please see Figure 1 This application provides a control structure 100 including a housing 1, a control unit, a plurality of first sensors 2, and an isolator 11. The housing 1 has a mounting groove 1a; each of the first sensors 2 is spaced apart in the mounting groove 1a, and each of the first sensors 2 is used to detect airflow; the control unit is electrically connected to the first sensors 2; the isolator 11 is disposed in the mounting groove 1a and is used to isolate two adjacent first sensors 2 to prevent crosstalk of airflow signals received by each first sensor 2.

[0026] In this embodiment, the housing 1 is made of lightweight, high-strength plastic or aluminum alloy, providing not only good durability and aesthetics but also ensuring a comfortable wearing experience for the user. The housing 1 has a mounting slot 1a located on the side of the earphone furthest from the user, facilitating gesture operation. The first sensor 2 can be a MEMS flow sensor or a miniature airflow sensor, which can detect airflow and features high sensitivity and fast response. The control unit uses a micro-integrated circuit chip, installed inside the housing 1, and is electrically connected to the first sensor 2 via a flexible circuit board. The control unit can process the sensor signals in real time and control the Bluetooth earphone 200 to execute preset function commands, such as switching tracks, pausing playback, or adjusting volume. The isolator 11 can be an accessory part independent of the housing 1 or a boss integrally formed with the housing 1. The isolator 11 is stably connected to the housing 1 by bolts, clips, or adhesive. The isolator 11 effectively blocks air crosstalk between adjacent first sensors 2, ensuring that each first sensor 2 can detect airflow in the corresponding direction and convert it into an electrical signal transmitted to the control unit.

[0027] The control structure 100 of this application achieves precise gesture control and effectively reduces false triggering by setting multiple first sensors 2 and isolating components 11 between adjacent first sensors 2. Specifically, the first sensors 2 detect airflow to ensure that the operation is only executed when the user actually makes a gesture. For example, when a user wants to change a music track, they can make a specific gesture, such as waving their hand to the left on the mounting slot 1a. The first sensors 2 detect the direction of airflow near the mounting slot 1a, and the control unit executes the track switching command after verifying the signal from the first sensors 2. This mechanism of isolating airflow in adjacent positions through the isolating components 11 greatly reduces the possibility of false triggering and improves user convenience and satisfaction. In addition, the sensor types and materials used in the control structure 100 of this application contribute to a small size and lightweight design, allowing it to be easily integrated into the Bluetooth headset 200 without increasing the size or weight of the headset.

[0028] Please see Figure 1 The control structure also includes a second sensor 3, which is located in the middle of the mounting slot 1a. The second sensor 3 is used to detect control gestures. The control unit is electrically connected to the second sensor 3. After the second sensor 3 detects a control gesture, the first sensor 2 can detect airflow so that the control unit can control the Bluetooth headset to execute function commands.

[0029] In one embodiment, a second sensor 3 is added to the control structure. The second sensor 3 is fixed in the middle of the mounting slot 1a and electrically connected to the control unit. The control unit has two levels of enabled logic. The second sensor 3 prioritizes detecting control gestures. Only after it outputs a valid gesture signal will the control unit power on and activate each of the first sensors 2 to enter the airflow detection state. Subsequently, the control unit controls the Bluetooth headset to execute the corresponding function command based on the airflow signal returned by the first sensors 2. The isolator 11 simultaneously blocks airflow crosstalk between adjacent first sensors 2, ensuring that the gesture detection area and the airflow detection area work independently. Through the two-level triggering sequence of gesture verification by the second sensor 3 and airflow confirmation by the first sensor 2, false wake-ups caused by ambient airflow or accidental touch are completely avoided, significantly reducing power consumption and improving command recognition accuracy. At the same time, the second sensor 3 is integrated into the existing mounting slot 1a without adding openings or occupying additional space in the housing 1. While maintaining the miniaturization and lightweight of the headset, it achieves precise coordination of gesture and airflow composite control, enhancing the overall interaction reliability.

[0030] Please see Figure 1 In order to concentrate the airflow entering the first sensor 2 and ensure the stability of detection, the isolation component 11 includes multiple baffles 12. Both ends of the baffles 12 have gaps with the housing 1. An airflow channel 1b is formed between two adjacent baffles 12. Each first sensor 2 is placed in an airflow channel 1b.

[0031] In one embodiment, multiple baffle plates 12 are integrally molded within the mounting groove 1a of the housing 1 using an injection molding process. These baffle plates 12 are spaced apart along the length of the mounting groove 1a, with their axial ends maintaining a certain gap from the inner wall of the housing 1, preventing complete contact with the housing 1. An airflow channel 1b is naturally formed between adjacent baffle plates 12. Each first sensor 2 is individually placed within an airflow channel 1b and electrically connected to the control unit via a flexible circuit board. This structural design ensures that the airflow entering the mounting groove 1a can only reach the first sensor 2 through these airflow channels 1b. The airflow is concentrated and guided within the channels, improving the stability of the airflow and the accuracy of the first sensor 2's detection.

[0032] Please see Figure 1 In order to receive as much airflow as possible, the isolation component 11 includes multiple baffles 12, which divide the mounting slot 1a into multiple independent chambers, and each first sensor 2 is placed in a separate chamber.

[0033] In this embodiment, multiple baffles 12 are provided within the mounting slot 1a of the housing 1, dividing the mounting slot 1a into multiple independent chambers. Each first sensor 2 is placed individually within a chamber and electrically connected to the control unit via a flexible circuit board. The two ends of the baffles 12 are tightly fitted to the housing 1, ensuring that each chamber is independent and preventing crosstalk between different chambers. Through this design, each first sensor 2 can receive airflow from a specific direction within its chamber, thereby improving the sensitivity and accuracy of airflow detection. By dividing the mounting slot 1a into multiple independent chambers, and placing each first sensor 2 individually within a chamber, the system can maximize the reception of airflow from a specific direction, avoiding mutual interference between different sensors and significantly improving the sensitivity and accuracy of airflow detection. This design not only improves signal stability and reliability but also enables more accurate recognition of user gestures, enhancing the user experience.

[0034] In one embodiment, the airflow channel 1b is designed to maximize the intake of airflow to improve the detection sensitivity of the airflow sensor. Specifically, the inner wall of the airflow channel 1b forms a gradually expanding structure. This structure results in the airflow channel 1b having a smaller cross-sectional area in the middle of the mounting groove 1a, while the cross-sectional area gradually increases as it extends towards the periphery. For example, the airflow channel 1b can be designed as a conical or horn-shaped channel, with a larger cross-sectional opening located at the periphery of the mounting groove 1a and a smaller cross-sectional opening located in the middle. This design guides more airflow into the airflow channel 1b, thereby improving the detection efficiency of the airflow sensor.

[0035] In this embodiment, the special design of the airflow channel 1b significantly improves the detection performance of the airflow sensor. By gradually increasing in size from the end closest to the second sensor 2 to the end furthest from the second sensor 2, the airflow channel 1b can more effectively capture and guide airflow, thereby improving the sensor's sensitivity to changes in airflow. For example, when a user performs a gesture operation, this design ensures that more airflow is guided to the sensor, reducing detection failures due to insufficient airflow. Furthermore, this gradually expanding structure reduces turbulence when the airflow enters the airflow channel 1b, further improving detection accuracy. Both the conical and horn-shaped airflow channel 1b designs effectively increase the amount of airflow received, thereby improving the accuracy and reliability of gesture recognition. This design not only enhances the user experience but also provides more stable technical support for the gesture control function of the Bluetooth headset 200.

[0036] Please see Figure 1In this embodiment, the isolator 11 and the housing 1 are integrally injection molded or die-cast. An airflow channel 1b is naturally formed between adjacent barrier plates 12. The first sensor 2 is directly attached to the airflow channel 1b without the need for additional fixing parts. During assembly, the first sensor 2 only needs to be placed into the airflow channel 1b and glued once to complete the positioning, simplifying the process and ensuring dimensional accuracy. The integral molding eliminates the assembly gap between the isolator 11 and the housing 1, completely avoiding airflow leakage and sensor displacement. The position and cross-sectional dimensions of the airflow channel 1b are formed in one step in the mold, resulting in good batch consistency. It eliminates the need for accessories such as clips and screws, reducing material and labor costs, while improving the overall strength and sealing level of the housing. When the isolator 11 and the housing 1 are detachable structures, they can be connected by snap-fit ​​or screw connection. This detachable connection method facilitates the user to disassemble and replace the isolator 11, and also facilitates the manufacturer to assemble it during production.

[0037] Please see Figure 1 During long-term use, in order to prevent external debris from damaging or obstructing the structures such as the first sensor 2 and the second sensor 3 on the mounting slot 1a, a protective component 4 is provided on the periphery of the mounting slot 1a. The protective component 4 is a mesh structure.

[0038] In one embodiment, the mesh-structured protective element 4 effectively blocks dust, liquid, and other debris while allowing airflow to pass freely, ensuring the normal operation of the sensor. The protective element 4 can be made of metal wire mesh or high-strength plastic fiber mesh, and is fixed to the periphery of the mounting groove 1a by means of clips, threads, or adhesives. For example, the protective element 4 can be designed as a metal wire mesh cover, fixed to the periphery of the mounting groove 1a by clips. It should be noted that the protective element 4 can be made of stainless steel metal wire mesh with a mesh size of 1 mm, fixed to the periphery of the mounting groove 1a by clips; the protective element 4 can also be made of nylon plastic fiber mesh with a mesh size of 1.5 mm, fixed to the periphery of the mounting groove 1a by threads. These designs effectively prevent external debris from entering the mounting groove 1a, protecting the normal operation of the sensor, while not affecting airflow detection.

[0039] By setting a mesh-structured protective element 4 around the periphery of the mounting slot 1a, damage or obstruction of the first sensor 2 and the second sensor 3 by external debris is effectively prevented, ensuring long-term stable operation of the sensors. The mesh-structured protective element 4 not only provides physical protection but also allows airflow to pass freely, thus not affecting the sensor's detection function. For example, when the user uses headphones, the protective element 4 can prevent dust and liquid from entering the mounting slot 1a, ensuring that the sensor's detection accuracy is not affected. Furthermore, the mesh design of the protective element 4 does not obstruct airflow, ensuring the reliability of the gesture control function. In specific embodiments, both stainless steel wire mesh and nylon plastic fiber mesh can effectively protect the sensors while maintaining the integrity of their detection function. This design not only improves the durability and reliability of the Bluetooth headset 200 but also provides users with a more stable and convenient user experience.

[0040] Please see Figure 1 This application also proposes a Bluetooth headset 200, including a control structure 100 and a control center, the control center being electrically connected to a control unit, and the control center being used for Bluetooth communication with electronic devices.

[0041] In one embodiment of this application, the control structure 100 is responsible for detecting the user's gestures and generating corresponding control signals, while the control center is responsible for processing these signals and communicating with external electronic devices via Bluetooth. Specifically, the control center can employ an integrated Bluetooth module, which is connected to the control unit via a conductive path on a circuit board. For example, the control center can be a chip supporting the Bluetooth 5.0 standard, capable of stable connection with smartphones, tablets, or other Bluetooth devices. Inside the headset, the control center and control unit are connected via a flexible circuit board to ensure the stability and reliability of signal transmission. By introducing a control center into the Bluetooth headset 200, this application significantly improves the functionality and user experience of the headset. The electrical connection between the control center and the control unit enables the headset to quickly respond to the user's gesture operations and convert these operations into corresponding control commands, which are then sent to external devices via Bluetooth communication. For example, the user can control music playback, answer calls, or adjust volume through simple gesture operations, while the control center ensures the accuracy and timeliness of these operations.

[0042] Please see Figure 1 To ensure that users do not need to find the angle for gesture operation when wearing the headphones, the control structure has four first sensors 2, and the isolation component 11 includes four barrier plates 12. An airflow channel 1b is provided between two adjacent barrier plates 12, and each first sensor 2 is contained within an airflow channel 1b. When the Bluetooth headphones are worn, two airflow channels 1b are arranged in a vertical direction, and the other two airflow channels 1b are arranged in a horizontal direction.

[0043] In this embodiment, to enable users to perform gesture operations more naturally after wearing the Bluetooth headset 200 without having to deliberately find a specific operating angle, the mounting slot 1a is specially designed with four airflow channels 1b. These four airflow channels 1b are evenly spaced along the periphery of the mounting slot 1a, and each airflow channel 1b houses and defines a first sensor 2. When the Bluetooth headset 200 is worn, two airflow channels 1b are positioned perpendicularly (i.e., up-down), and the other two airflow channels 1b are positioned horizontally (i.e., left-right). This layout ensures that any natural gesture operation by the user can be detected by the corresponding sensor. For example, when the user waves their hand up or down, the sensor in the perpendicular direction can detect the airflow change; when the user waves their hand left or right, the sensor in the horizontal direction can detect the airflow change.

[0044] By setting four airflow channels 1b on the mounting slot 1a and evenly distributing the sensors along the vertical and horizontal directions, the gesture control performance of the Bluetooth headset 200 is significantly improved. This layout allows the headset to detect airflow changes in multiple directions, thereby enabling richer and more flexible gesture control functions. For example, users can control different functions of the headset, such as switching tracks, adjusting volume, and answering calls, by waving their hands up, down, left, and right. This all-around detection capability not only improves the user experience but also reduces the possibility of false triggers. In specific lower embodiments, both circular and square mounting slot 1a designs effectively improve the detection range and accuracy of the sensors, ensuring that user gestures in different directions can be accurately recognized. This design not only improves the intelligence level of the Bluetooth headset 200 but also provides users with a more convenient and efficient operating method, allowing users to perform gesture operations more naturally after wearing the headset, without having to deliberately find specific operating angles.

[0045] Please see Figure 1 In order to make the Bluetooth headset 200 more compatible with the human ear canal, and to make it easier for the user to perform gesture operations above the mounting slot 1a when using the Bluetooth headset 200 of this application, the Bluetooth headset 200 includes an earplug 5, which is connected to the housing 1 and is located at the end of the housing 1 away from the mounting slot 1a.

[0046] In one embodiment, the earbud 5 may be made of soft silicone or memory foam material to ensure wearing comfort and stability. For example, the earbud 5 may be designed to be replaceable to accommodate different users' ear canal sizes. By designing the earbud 5 at the end of the housing 1 away from the mounting slot 1a, the Bluetooth headset 200 can better fit the human ear canal, while providing convenience for users to perform gesture operations above the mounting slot 1a. The soft material and replaceable design of the earbud 5 not only improve wearing comfort and stability but also reduce wearing fatigue caused by ear canal discomfort. For example, when a user wears the headset for a long time, the soft earbud 5 can provide comfortable support without causing ear discomfort. In addition, the position design of the earbud 5 ensures that the user's hand is not interfered with by the earbud 5 when performing gesture operations, thereby improving the convenience and accuracy of operation.
