DETAILED DESCRIPTION

[0046] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0047] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0049] As can be seen from the background technology, with the development of the electronics industry, electronic products such as smart phones and tablet computers have been widely used in people's daily lives. As an important accessory of the above electronic products, Bluetooth headsets are becoming more and more popular.

[0050] A Bluetooth headset is a wireless headset that applies Bluetooth technology to the field of headphones. When in use, it is connected to a terminal device via a Bluetooth wireless antenna. At present, there is a clear trend towards miniaturization of Bluetooth headsets. However, since the RF antenna itself has relatively high requirements for space clearance, and in one structure of an ear clip-on headset, the headset is placed on the user's auricle by rotating the shaft 321 to achieve the purpose of clamping the ear. However, based on the high requirements for clearance of the Bluetooth wireless antenna, the existence of the shaft 321 will also occupy the internal space of the ear clip-on Bluetooth headset, making the internal electronic and structural stacking space more tense, which is not conducive to the miniaturization design of the product, and will also have an adverse effect on the transmission of RF antenna signals. To this end, this embodiment provides the following solution.

[0051] This embodiment provides an ear-clip Bluetooth headset, which changes the internal structure of the headset and uses a rotating component 30 as a radiator of the Bluetooth wireless antenna, thereby solving a series of problems such as the device product being large in size and not conducive to lightweight and miniaturized design.

[0052] Please refer to Figure 1-Figure 4 The ear clip type Bluetooth headset comprises a first clamping portion 10 and a second clamping portion 20. In terms of appearance, the first clamping portion 10 and the second clamping portion 20 are rotatably connected via a rotating assembly 30, and a clamping space 40 for clamping the user's auricle is formed between the first clamping portion 10 and the second clamping portion 20. In order to allow the user's ear to enter the clamping space 40 and be clamped by the first clamping portion 10 and the second clamping portion 20, the first clamping portion 10 and the second clamping portion 20 are separated from each other. The ends are matched to form a clamping opening 41 connected to the clamping space 40, and the relative position and angle between the first clamping part 10 and the second clamping part 20 can be adjusted by relative movement around the rotating component 30, that is, the size of the clamping space 40 and the clamping opening 41 can be adjusted by the relative movement of the first clamping part 10 and the second clamping part 20 around the rotating component 30, so that the clamping space 40 and the clamping opening 41 are narrowed or expanded, so that the ear clip type Bluetooth headset can be taken off from the user's auricle or put on the user's auricle.

[0053] As for the internal structure, a main board 50 is provided inside the first clamping part 10, and the main board 50 includes but is not limited to functional components such as a control chip, a functional chip, and a Bluetooth module. In addition, in the first clamping part 10, it is also used to install components such as an electroacoustic transducer 60, a battery 70, and a key switch. In the embodiment in which the first clamping part 10 is provided with an electroacoustic transducer 60, the first clamping part 10 is provided with an acoustic cavity and a sound outlet 131 for the electroacoustic transducer 60. Specifically, the sound emitted by the electroacoustic transducer 60 transmits the audio signal to the outside through the acoustic cavity and the sound outlet 131. Components such as the electroacoustic transducer 60 and the battery 70 can be connected to the main board 50 through a flexible circuit board.

[0054] Exemplarily, the ear clip type Bluetooth headset comprises a release position and a plurality of clamping positions. When the ear clip type Bluetooth headset is in the release position, such as Figure 1-Figure 4As shown, the distance between the ends of the first clamping portion 10 and the second clamping portion 20 that are opposite to each other is at the maximum or nearly maximum position. In this position, the first clamping portion 10 and the second clamping portion 20 will not clamp the user's auricle, that is, when the user needs to remove the ear clip type Bluetooth headset from the auricle, or needs to wear the ear clip type Bluetooth headset, the user can apply corresponding forces to the first clamping portion 10 and the second clamping portion 20, so that the two can move to the release position, so as to facilitate the removal of the ear clip type Bluetooth headset or readjust the relative positions of the first clamping portion 10 and the second clamping portion 20 for wearing. When the ear-clip Bluetooth headset is in one of the clamping positions, the first clamping part 10 and the second clamping part 20 move around the rotating component 30 from the release position to a certain angle. In this state, the distance between the ends of the first clamping part 10 and the second clamping part 20 that want to separate is smaller than the distance between the ends of the first clamping part 10 and the second clamping part 20 that want to separate in the released state. The user can adjust the relative position of the first clamping part 10 and the second clamping part 20 according to his or her own wearing habits, auricle size, structure, etc., so that the size of the clamping space 40 and the clamping opening 41 are adapted to the user's ear, so that the ear-clip Bluetooth headset can be stably clamped on the user's auricle through the first clamping part 10 and the second clamping part 20 to complete the wearing.

[0055] Specifically, when the ear clip type Bluetooth headset is worn on the user's ear, the first clamping part 10 provided with the electroacoustic transducer 60 is at least partially placed in the concha cavity, and the second clamping part 20 is located on the back side of the auricle, such as the back side of the helix or the back side of the antitragus.

[0056] Please continue to refer to Figure 1-Figure 9 The main board 50 is located in the first clamping portion 10 and can be supported and fixed by the first clamping portion 10. The main board 50 can be configured as the above-mentioned circuit board integrating different chips and modules, or an antenna board only provided with an antenna module. However, no matter what structural form of the main board 50 is adopted, the main board 50 of this embodiment needs to be provided with an antenna circuit and an antenna feeding point connected to the antenna circuit. The rotating component 30 is electrically connected to the antenna circuit through the antenna feeding point. Generally, two antenna feeding points are generally provided on the antenna circuit, and the rotating component 30 is respectively connected to the above-mentioned two antenna feeding points, so that the antenna circuit and the rotating component 30 are connected to form a loop, so that the antenna circuit can receive and send antenna signals through the rotating component 30.

[0057] In connection with the above technical solution, it should be understood that the rotating component 30 can be made of metal with high conductivity as its production material, such as aluminum, stainless steel, iron, etc., so that the rotating component 30 can play the role of a radiator in the application of the ear clip type Bluetooth headset. In one embodiment, the rotating shaft 321 component can be configured as a lightweight aluminum material to make it suitable for the lightweight design of the ear clip type Bluetooth headset. In order to avoid rust and other problems, aluminum materials generally use hard oxidation and other processes to form an oxide layer with insulating properties on its surface, which will cause the surface of the rotating component 30 to lose its conductive properties and cannot be connected to the antenna feeding point. To solve this problem, in the above case, the rotating component 30 can be milled, ground, etc. to expose the conductive part in the oxide layer, so that the rotating component 30 can be connected to the antenna feeding point of the antenna circuit through the exposed conductive part.

[0058] According to the technical solution provided above, the first clamping part 10 and the second clamping part 20 of the ear clip type Bluetooth headset can achieve angle adjustment through the rotating assembly 30, so that the first clamping part 10 and the second clamping part 20 can be adjusted according to the needs of the user and clamped on the auricle more stably. Compared with the solution that the two clamping parts of the traditional ear clip type Bluetooth are generally connected by an elastic body, the relative position and angle between the first clamping part 10 and the second clamping part 20 of this embodiment can be adjusted according to the user's wearing habits, ear structure and other factors, avoiding the occurrence of situations that are difficult to adapt to the user's wearing due to excessively thick ears causing excessive clamping force, or too thin ears causing too small clamping force, etc., meeting the wearing needs of different users and improving the user's wearing experience.

[0059] It is worth mentioning that in order to adapt to the human ear structure, the ear clip-type Bluetooth headset of this embodiment has a protrusion 23 formed on one side of the second clamping part 20 close to the clamping space 40, so that when the user wears the ear clip-type Bluetooth headset, the protrusion 23 of the second clamping part 20 can match the structure of the back side of the user's auricle, thereby improving the wearing experience.

[0060] In addition, the rotating assembly 30 is used as the radiator of the Bluetooth wireless antenna, so that the rotating assembly 30 plays the role of sending and receiving signals, and the solution of additionally configuring an antenna radiator in the traditional Bluetooth headset in the device is abandoned, which reduces the number of materials in the product and reduces the material cost of the product. The installation space reserved for the traditional Bluetooth wireless antenna can be saved inside the device. Since an independent Bluetooth wireless antenna is no longer used, the space occupancy rate of related material components inside the headset is also reduced, which is conducive to the layout of the functional modules inside the headset, improves the compactness and integrity of the whole machine, is suitable for the structural requirements of the narrow space in the headset, and enables the device product to be further designed in the direction of miniaturization and lightweight. In addition, the clearance area of ​​the rotating assembly 30 in the device is relatively large. Compared with the relevant technology, the size of the rotating assembly 30 is larger than the traditional Bluetooth wireless antenna, which can also make the antenna signal transmission of the headset more stable and improve the user experience.

[0061] Please continue to refer to Figure 5-Figure 11 As a specific embodiment of the rotating assembly 30, the rotating assembly 30 includes a first rotating member 31 and a second rotating member 32, wherein the first rotating member 31 is fixedly connected to the first clamping portion 10, the first end of the first rotating member 31 is electrically connected to the antenna circuit through the antenna feeding point, and the second end of the first rotating member 31 is extended toward the end of the first clamping portion 10 close to the second clamping portion 20. Here, the second end of the first rotating member 31 can be set at a position as far away from the main board 50 and the electronic components set on the first clamping portion 10 as possible, so that the rotating assembly 30 can expand its clearance area when the seat antenna radiator is used, and reduce the interference caused by the main board 50 and related components to the signals received and sent by it. The first end of the second rotating member 32 is installed on the second clamping portion 20, and the second end of the second rotating member 32 is rotatably matched with the second end of the first rotating member 31.

[0062] Specifically, the second end of the first rotating member 31 is at least partially exposed from the first clamping portion 10, and the second end of the second rotating member 32 is at least partially exposed from the second clamping portion 20. The exposed portions of the first rotating member 31 and the second rotating member 32 form a rotational fit. Through the rotational fit of the first rotating member 31 and the second rotating member 32, when the first clamping portion 10 and the second clamping portion 20 are pushed, the two rotate relative to each other around their rotation axes through the first rotating member 31 and the second rotating member 32, thereby providing a stable rotational connection and structural strength.

[0063] Following the above implementation, in order to have a further understanding of the present solution, the relative positions of the first clamping portion 10 and the second clamping portion 20 corresponding to the rotating assembly 30 are described below according to the different position states of the ear clip type Bluetooth headset in the above description.

[0064] Please refer to Figure 5The second rotating member 32 and the second clamping portion 20 include a release position around the X-axis that is relatively far away from the first rotating member 31 and the first clamping portion 10. Exemplarily, the first rotating member 31 and the first clamping portion 10 form a first cycloid L1 from one end close to the second rotating member 32 and the second clamping portion 20 to one end away from the second rotating member 32 and the second clamping portion 20. The second rotating member 32 and the second clamping portion 20 form a second cycloid L2 from one end close to the first rotating member 31 and the first clamping portion 10 to one end away from the first rotating member 31 and the first clamping portion 10. Here, the connection between the first cycloid L1 and the second cycloid L2 can be regarded as the rotation axis of the X-axis of the rotating component 30. When the ear clip type Bluetooth headset is in the release position, the relative angle between the first cycloid L1 and the second cycloid L2 around the X-axis is at or close to 180°.

[0065] Please refer to Figure 6 When the ear-clip Bluetooth headset is in any clamping position, referring to the above-mentioned limiting method, the relative angle between the first cycloid L1 and the second cycloid L2 around the X-axis is less than 180°. As shown in the figure, the first cycloid L1 and the second cycloid L2 can be at a 90° position, thereby clamping and fixing the user's auricle.

[0066] Based on the above embodiment, the rotating component 30 can use the first rotating member 31, or the first rotating member 31 and the second rotating member 32 as an antenna radiator, wherein, regardless of the technical solution of using only the first rotating member 31 as the antenna radiator, or the technical solution of using the first rotating member 31 and the second rotating member 32 as the antenna radiator at the same time, the first rotating member 31 needs to be configured as a conductor, and the first end of the first rotating member 31 needs to be connected to the antenna circuit through the antenna feeding point, so that it can provide the function of sending and receiving signals.

[0067] In one embodiment, the first end of the first rotating member 31 can be fixed to the main board 50 by welding. Here, the first rotating member 31 and the antenna feeding point can be connected by solder or other solder, so that the two can be connected and form a hard connection relationship under the action of the solder.

[0068] In another embodiment, a conductive spring sheet (not shown) is provided on the mainboard 50 at the antenna feeding point, and the conductive part of the first rotating member 31 can achieve conduction with the antenna circuit by abutting against the conductive spring sheet. The first rotating member 31 presses against the conductive spring sheet, so that the conductive spring sheet is in a compressed state under the action of the first rotating member 31, thereby continuously applying a force of pressing against each other to the first rotating member 31, thereby ensuring stable conduction between the antenna circuit and the first rotating member 31. Of course, in another embodiment, the conductive spring sheet can also be provided on the first rotating member 31, so that the first rotating member 31 presses against the antenna feeding point on the mainboard 50 through the conductive spring sheet, thereby achieving conduction between the first rotating member 31 and the antenna circuit.

[0069] It is understandable that since the ear-clip Bluetooth headset needs to be frequently adjusted and switched between different position states according to the user's putting on and taking off, as well as the user's wearing habits and other factors, although the first rotating member 31 and the first clamping portion 10 are in a relatively fixed state, the two will still have relative displacement as the ear-clip Bluetooth headset is used. In order to compensate for the position deviation caused by the relative displacement of the first rotating member 31 and the first clamping portion 10, this embodiment can adopt a solution of setting a conductive spring sheet between the main board 50 and the first rotating member 31, so as to ensure a stable connection relationship between the main board 50 and the first rotating member 31 through the elastic deformation ability of the conductive spring sheet.

[0070] Of course, the conductive structure between the first rotating part 31 and the antenna circuit of the present scheme is not limited to the above two specific implementations. The antenna feeding point and the first rotating part 31 can also achieve stable physical and electrical connection through different assembly processes and structures such as conductive tape bonding and snap-fit ​​structure limiting.

[0071] In one embodiment, the second end of the second rotating member 32 is arranged at an end of the second clamping portion 20 close to the first clamping portion 10, and the first end of the second rotating member 32 is extended toward the end of the second clamping portion 20 away from the first clamping portion 10. In this way, whether it is the first rotating member 31 or the second rotating member 32, it is located in the first clamping portion 10 and the second clamping portion 20 to form a portion extending in a certain direction, thereby improving the connection strength between the first rotating member 31 and the first clamping portion 10, between the second rotating member 32 and the second clamping portion 20, and between the first clamping portion 10 and the second clamping portion 20, thereby improving the integrity of the ear clip type Bluetooth headset. At the same time, it can be understood that most of the first rotating member 31 and the second rotating member 32 are respectively placed in the first clamping portion 10 and the second clamping portion 20, so that the first clamping portion 10 and the second clamping portion 20 can provide most of the protection of the first rotating member 31 and the second rotating member 32, and the first rotating member 31 and the second rotating member 32 only need to realize the rotational cooperation part exposed outside the first clamping portion 10 and the second clamping portion 20.

[0072] Optionally, the first clamping portion 10 and the second clamping portion 20 can be supported by a material (such as plastic) that is relatively light in weight and has good wear resistance, corrosion resistance and other properties, thereby providing good protection for components such as the first rotating member 31, the second rotating member 32 and the main board 50 inside the headset, while also being conducive to the lightweight design of the ear-clip type Bluetooth headset.

[0073] Based on the above description of the specific structural form of the second rotating member 32, in an embodiment in which both the first rotating member 31 and the second rotating member 32 are used as antenna radiators, the second rotating member 32 and the first rotating member 31 are also conductors, and the first rotating member 31 and the second rotating member 32 rotate in coordination and form a good electrical connection relationship. In this embodiment, the shaft 321 component serving as antenna radiation allows the second rotating member 32 to extend along the inside of the second clamping portion 20 in a direction away from the first clamping portion 10, making full use of the spatial position of the second clamping portion 20, so that the antenna radiator is larger in size than a traditional Bluetooth wireless antenna, thereby expanding the volume of the antenna radiator and improving its sensitivity in sending and receiving signals.

[0074] Continuing with the technical solution of using the first rotating member 31 and the second rotating member 32 as antenna radiators, in this embodiment, the part of the first rotating member 31 used for fixed connection with the first clamping part 10 is a plate, and the part of the second rotating member 32 used for installation on the second clamping part 20 is a plate. On the basis of using the first rotating member 31 and the second rotating member 32 as antenna radiators, the surface areas of the two are further expanded, so that the signal receiving and transmitting strength of the shaft 321 component is stronger than that of the transmission Bluetooth wireless antenna. In addition, the second rotating member 32 extends from one end close to the first rotating member 31 to the end away from the first rotating member 31, which can further expand the clearance area of ​​the rotating component 30 as the antenna radiator and improve the stability of the antenna circuit.

[0075] At the same time, using a plate as the part of the first rotating member 31 placed in the first clamping part 10, and using a plate as the part of the second rotating member 32 placed in the second clamping part 20, can increase the connection surface between the first rotating member 31 and the first clamping part 10, and between the second rotating member 32 and the second clamping part 20, thereby improving the connection strength between the first clamping part 10, the rotating assembly 30 and the second clamping part 20.

[0076] It should be understood that the plate parts of the first rotating member 31 and the second rotating member 32 can be a combination of one or more types of planar plate structures, arc-shaped plate structures, etc.

[0077] In one embodiment, the first rotating member 31 and the second rotating member 32 of this embodiment are assembled in a manner that cooperates with the shaft hole 311. On the basis of ensuring that the first rotating member 31 and the second rotating member 32 can stably rotate around the shaft hole 311, the first rotating member 31 and the second rotating member 32 can maintain a point connection relationship regardless of their relative angle position state, so that the first rotating member 31 and the second rotating member 32 provide stable signal receiving and sending functions.

[0078] As one of the specific schemes of this implementation, please refer to Figure 5-Figure 11 A shaft hole 311 is formed at a second end of the first rotating member 31 exposed outside the first clamping portion 10 , and a rotating shaft 321 is correspondingly formed at a second end of the second rotating member 32 exposed outside the second clamping portion 20 .

[0079] Of course, as another specific solution of this embodiment, the second end of the first rotating member 31 may also be provided with a rotating shaft 321 , and correspondingly, the second end of the second rotating member 32 should be provided with a shaft hole 311 .

[0080] In the above scheme, the structure of the rotating shaft 321 is adapted to the shaft hole 311, so that the rotating shaft 321 can be rotatably inserted into the shaft hole 311 while maintaining the contact between the rotating shaft 321 and the wall of the shaft hole 311. In this way, no matter where the first clamping part 10 and the second clamping part 20 are rotated around the rotation axis of the rotating shaft 321 and the shaft hole 311 to any position angle, the first rotating member 31 and the second rotating member 32 can still ensure the conductive connection between the two by the matching manner of the rotating shaft 321 and the wall of the shaft hole 311, thereby providing a stable antenna signal receiving and transmitting function.

[0081] Specifically, when an axial hole 311 is provided at the second end of the first rotating member 31 and a rotating shaft 321 is provided at the second end of the second rotating member 32, the component with the axial hole 311 and the first rotating member 31, as well as the rotating shaft 321 and the second rotating member 32 can be an integral part, or they can be independently processed and formed and connected through a subsequent assembly process or assembly structure; similarly, when a rotating shaft 321 is provided at the second end of the first rotating member 31 and an axial hole 311 is provided at the second end of the second rotating member 32, the component with the axial hole 311 and the second rotating member 32, as well as the rotating shaft 321 and the first rotating member 31 can be an integral part, or they can be independently processed and formed and connected through a subsequent assembly process or assembly structure. Regardless of which of the above-mentioned structural forms is adopted, in the implementation method of assembling the rotating shaft 321 and the axial hole 311, the hole wall of the axial hole 311 needs to be arranged around the circumference of the rotating shaft 321 to achieve the purpose of at least partially surrounding the outer periphery of the rotating shaft 321, ensuring that the outer peripheral surface of the rotating shaft 321 and the hole wall of the axial hole 311 are at least partially in contact.

[0082] In one embodiment, taking the scheme in which the second end of the first rotating member 31 is provided with an axial hole 311 as an example, the second end of the first rotating member 31 can be provided with a plurality of guide portions 313 spaced apart from each other around the circumference of the rotating shaft 321, and the plurality of guide portions 313 enclose and define the axial hole 311, and each guide portion 313 extends from one end of the body connected to the first rotating member 31 to one end of the body away from the first rotating member 31, so as to define an opening of the axial hole 311 at one end of the body of each guide portion 313 away from the first rotating member 31, so that the rotating shaft 321 can be inserted into the axial hole 311 defined by the plurality of guide portions 313 through the opening, and at the same time, a hollow structure is formed between any two adjacent guide portions 313, so as to save the material cost of the component for providing the axial hole 311 to a certain extent.

[0083] According to the above structural form, similarly, in the embodiment where the second end of the second rotating member 32 is provided with an axial hole 311 , the second end of the second rotating member 32 can also be provided with a plurality of guide portions 313 spaced apart from each other and surrounding the circumference of the rotating shaft 321 .

[0084] According to the above technical solution, in this embodiment, the first rotating member 31 and the second rotating member 32 are rotationally matched by cooperating with the shaft hole 311, so that the two can meet the conditions of stable rotation and maintaining electrical contact. At the same time, the outer peripheral surface of the rotating shaft 321 and the hole wall of the shaft hole 311 are matched by surface contact, which can effectively increase the contact area between the first rotating shaft 321 component and the second rotating member 32, so that the signal can be stably transmitted between the first rotating member 31 and the second rotating member 32.

[0085] Continuing with the example of the solution in which the first rotating member 31 and the second rotating member 32 are rotatably connected by cooperating with the shaft hole 311, a stable matching relationship is formed between the outer circumferential surface of the rotating shaft 321 and the shaft hole 311 through the first limiting portion 322 disposed on the rotating shaft 321 and the second limiting portion 312 on the shaft hole 311, so that the rotating shaft 321 is located in the shaft hole 311 and can still maintain a state of being stopped relative to the shaft hole 311 under a certain range of external force, thereby preventing the first clamping portion 10 and the second clamping portion 20 from rotating relative to each other when the user has not adjusted them, thereby affecting the user's wearing and the storage of the earphones.

[0086] According to the above description, the release position and multiple clamping positions between the first clamping portion 10 and the second clamping portion 20 can be specifically defined between the rotating shaft 321 and the shaft hole 311 by the matching state between the first limiting portion 322 and the second limiting portion 312. In one embodiment, at least one first limiting portion 322 is provided on the rotating shaft 321, and correspondingly, a plurality of second limiting portions 312 arranged at intervals are provided on the hole wall of the shaft hole 311 around the rotating shaft 321. The first limiting portion 322 and the second limiting portion 312 are structurally adapted so that the first limiting portion 322 and the second limiting portion 312 can be in a limited matching state to limit the relative rotation of the rotating shaft 321 and the shaft hole 311. In this embodiment, since a plurality of second limiting portions 312 surrounding the rotating shaft 321 are provided on the hole wall of the shaft hole 311, when the rotating shaft 321 is located in the shaft hole 311 and rotates, the first limiting portion 322 provided on the rotating shaft 321 can be in each second limiting portion 312. When the first limiting portion 322 rotates with the rotating shaft 321 to a state where it is aligned with any second limiting portion 312, the first limiting portion 322 will form a limiting match with the corresponding second limiting portion 312. In this way, the user can adjust the first clamping portion 10 and the second clamping portion 20 according to their specific needs to make the rotating shaft 321 and the shaft hole 311 rotate relatively with the first clamping portion 10 and the second clamping portion 20 respectively, and stop rotating in the corresponding position state, so that the first limiting portion 322 is restricted by the second limiting portion 312 at the corresponding position, so that the first clamping portion 10 and the second clamping portion 20 remain stable during the non-adjustment process.

[0087] In another embodiment, a plurality of first limiting portions 322 are arranged on the rotating shaft 321 around its rotation axis at intervals, and at least one second limiting portion 312 is arranged on the hole wall of the shaft hole 311. Similarly, the first limiting portion 322 and the second limiting portion 312 are structurally adapted so that the first limiting portion 322 and the second limiting portion 312 can be in a limited matching state to limit the relative rotation of the rotating shaft 321 and the shaft hole 311. In this embodiment, since a plurality of first limiting portions 322 arranged around its rotation axis are arranged on the outer circumference of the rotating shaft 321, when the rotating shaft 321 is located in the shaft hole 311 and rotates, the second limiting portions 312 arranged on the hole wall of the shaft hole 311 can be in each first limiting portion 322. When the second limiting portion 312 rotates with the shaft hole 311 to a state where it is aligned with any first limiting portion 322, the second limiting portion 312 will form a limiting match with the corresponding first limiting portion 322. In this way, the user can adjust the first clamping portion 10 and the second clamping portion 20 according to their specific needs to make the rotating shaft 321 and the shaft hole 311 rotate relatively with the first clamping portion 10 and the second clamping portion 20 respectively, and stop rotating at the corresponding position state, so that the second limiting portion 312 is restricted by the first limiting portion 322 at the corresponding position, so that the first clamping portion 10 and the second clamping portion 20 remain stable during the non-adjustment process.

[0088] According to the above-mentioned embodiment in which the first rotating member 31 and the second rotating member 32 can rotate relative to each other and can form a stable state in a preset position, the first limiting portion 322 and the second limiting portion 312 should be configured to maintain limiting cooperation within a first preset force range, and to disengage cooperation within a second preset force range, wherein the second preset force range is greater than the first preset force range. In one embodiment, at least one of the first limiting portion 322 and the second limiting portion 312 is configured to have a certain plastic deformation capacity, that is, under the action of the above-mentioned second preset force, the first limiting portion 322 and / or the second limiting portion 312 can be deformed, and recover or maintain its original state when the external force is lost or the first preset force is applied. In this way, under normal conditions, the first limiting portion 322 and the second limiting portion 312 can form a limiting matching state, and when the relative angular position of the first clamping portion 10 and the second clamping portion 20 needs to be adjusted, the user can apply a second preset force to the first clamping portion 10 and the second clamping portion 20 to rotate around the rotating component 30, so that the first limiting portion 322 and / or the second limiting portion 312 are deformed and disengaged, thereby allowing the rotating shaft 321 and the shaft hole 311 to rotate relative to each other, thereby achieving adjustment of the first clamping portion 10 and the second clamping portion 20. When the first clamping portion 10 and the second clamping portion 20 are rotated to the angular position required by the user, the user releases the first clamping portion 10 and / or the second clamping portion 20, so that the first limiting portion 322 at the corresponding position and the second limiting portion 312 at the corresponding position re-form a matching relationship, thereby restricting and locking the first clamping portion 10 and the second clamping portion 20 at the desired angle, thereby completing the adjustment of the ear-clip Bluetooth headset.

[0089] like Figure 7-Figure 11 As shown, in the present embodiment, the first limiting portions 322 and the second limiting portions 312 are both provided in plural numbers, and the number of the first limiting portions 322 is equal to the number of the second limiting portions 312, and the intervals between any two adjacent first limiting portions 322 and any two adjacent second limiting portions 312 are equal, so that each first limiting portion 322 can form a limiting matching relationship with each second limiting portion 312 in a one-to-one correspondence, thereby improving the stability of the rotating shaft 321 and the shaft hole 311 in a non-rotating state.

[0090] It can be understood that the first limiting portion 322 and the second limiting portion 312 can be configured as matching protrusions and grooves, respectively, wherein the protrusion is embedded in the groove to achieve the anti-rotation of the rotating shaft 321 in the shaft hole 311. In this embodiment, the first limiting portion 322 is configured as a protrusion convexly arranged on the surface of the rotating shaft 321, and the second limiting portion 312 is a groove concavely arranged in the shaft hole 311, wherein the protruding direction of the protrusion is preferably perpendicular to the rotation axis of the rotating shaft 321, and the protrusion also extends along the axial direction of the rotating shaft 321, and correspondingly, the concave direction of the groove is also arranged perpendicular to the rotation axis of the rotating shaft 321, and the groove is arranged to extend along the axial direction of the rotating shaft 321, thereby increasing the contact area between the protrusion and the groove and improving the matching stability of the protrusion and the groove.

[0091] Taking the above-mentioned embodiment in which the shaft hole 311 is formed by a plurality of guide portions 313 as an example, a groove can be formed correspondingly at the hollow position between any two adjacent guide portions 313, that is, in the embodiment in which the shaft hole 311 is formed on the first rotating member 31, the second limiting portion 312 is a groove formed between any two adjacent guide portions 313, and the protrusion serving as the first limiting portion 322 can be clamped between any two adjacent guide portions 313, and the side of the guide portion 313 close to the rotating shaft 321 forms the hole wall of the shaft hole 311, so that the protrusion serving as the first guide portion 313 can be located therein and slide from one groove to another adjacent groove.

[0092] Please continue to refer to Figure 2 The first clamping part 10 has a recessed avoidance notch 11 at one end close to the second clamping part 20, and the second clamping part 20 has a convex connection block 21. The connection block 21 is at least partially movably disposed in the avoidance notch 11, and an avoidance gap is formed between the connection block 21 and the avoidance notch 11. The rotating assembly 30 is at least partially exposed to the outside of the first clamping part 10 and the second clamping part 20 through the avoidance gap, so as to facilitate the disassembly and assembly of the first clamping part 10, the second clamping part 20 and the rotating assembly 30.

[0093] In one embodiment, in an implementation where the rotating assembly 30 includes a first rotating member 31 and a second rotating member 32, the first end of the first rotating member 31 is placed in the first clamping portion 10, the second end of the first rotating member 31 is arranged in the avoidance gap, and the first end of the second rotating member 32 is arranged in the second clamping portion 20, and extends to the connecting portion and extends from the connecting portion to be placed in the avoidance gap, and rotates with the first rotating member 31.

[0094] Please refer to Figure 1-Figure 6 , Figure 8-Figure 9The first clamping portion 10 also includes an upper cover 12 and a lower cover 13. The upper cover 12 is installed on the lower cover 13 and encloses the lower cover 13 to form a hollow installation space. The electroacoustic transducer 60 (such as a speaker module, a pickup module, etc.), a battery 70, a charging interface 80, and a mainboard 50 and other devices can be arranged in the installation space. An opening connecting the installation space is opened between the upper cover 12 and the lower cover 13. The rotating assembly 30 is at least partially placed in the installation space and extends out of the first clamping portion 10 through the opening to be connected to the second clamping portion 20.

[0095] In the embodiment where the rotating assembly 30 includes a first rotating member 31 and a second rotating member 32, the first end of the first rotating member 31 is placed in the installation space, and the second end of the first rotating member 31 extends out of the first clamping portion 10 through the opening and rotates with the second rotating member 32. According to the embodiment where the first clamping portion 10 is provided with a position-avoiding notch 11, the opposite sides of the opening are connected to the installation space and the position-avoiding notch 11, respectively.

[0096] As a further implementation of the above scheme, a fixing bracket 14 is further provided in the installation space, a first installation space 15 is formed between the fixing bracket 14 and the upper cover 12, and a second installation space 16 is formed between the fixing bracket 14 and the lower cover 13. Specifically, the mainboard 50 is provided in the first installation space 15 and fixedly connected to the fixing bracket 14, the above-mentioned electroacoustic transducer 60 and the battery 70 are provided in the second installation space 16, and correspondingly, a sound outlet hole 131 connected to the second installation space 16 is opened on the lower cover 13.

[0097] In one embodiment, the fixed bracket 14 is provided with a charging interface 80 electrically connected to the mainboard 50. The mainboard 50 may be provided with a corresponding charging circuit so that the charging interface 80 is electrically connected to the battery 70 through the charging circuit of the mainboard 50. The charging interface 80 may use a pin to facilitate the quick matching of the ear clip type Bluetooth headset and the charging box. In the specific application scenario of the ear clip type Bluetooth headset, a charging box adapted to the ear clip type Bluetooth headset is also included. The ear clip type Bluetooth headset may be accommodated in the charging box. When the ear clip type Bluetooth headset is placed in the charging box, the pin on the ear clip type Bluetooth headset may form an electrical contact with the metal contact on the charging box, so that the power supply of the charging box and the battery 70 of the ear clip type Bluetooth headset are connected. When the battery 70 of the ear clip type Bluetooth headset is low in power, the power supply of the charging box may be used to charge the battery 70 of the ear clip type Bluetooth headset to improve the endurance of the Bluetooth headset.

[0098] In one embodiment, when the ear clip type Bluetooth headset is stored in the charging box, the ear clip type Bluetooth headset and the charging box can be magnetically attached to each other so that the ear clip type Bluetooth headset can be stably accommodated in the charging box, and the magnetic fixing method also facilitates the alignment of the pin of the headset with the metal contacts of the charging box.

[0099] Please refer to Figure 8 In a specific embodiment, a first magnetic component 90 is provided on at least one side of the fixing bracket 14 located on the charging interface 80, and correspondingly, a second magnetic component is provided on the side of the metal contact of the charging box. Here, the first magnetic component 90 and the fixing bracket 14 can be connected by glue fixation, double-sided tape fixation, snap fixation, screw fixation, etc., and a magnetic attraction force can be generated between the first magnetic component 90 and the second magnetic component, thereby fixing the ear clip type Bluetooth headset and the charging case together.

[0100] Continuing with the above embodiment, the first magnetic component 90 and the second magnetic component can both be magnets, and the magnetic poles of the first magnetic component 90 and the second magnetic component on the opposite side are opposite. For example, when the magnetic pole of the first magnetic component 90 facing the second magnetic component is the N pole, the magnetic pole of the second magnetic component facing the first magnetic component 90 is the S pole; or when the magnetic pole of the first magnetic component 90 facing the second magnetic component is the S pole, the magnetic pole of the second magnetic component facing the first magnetic component 90 is the N pole, thereby using the principle of magnets with opposite poles attracting each other to fix the Bluetooth headset and the charging case together. It can be understood that in other embodiments, only one of the first magnetic component and the second magnetic component can be set to be a magnetic component, and the other can be formed of a material that can be attracted by a magnet, such as one or more of iron, cobalt, and nickel.

[0101] In the above embodiment, the ear clip type Bluetooth headset supports and fixes the electroacoustic transducer 60, the battery 70, the charging interface 80, the first magnetic component 90 and the mainboard 50 through the fixing bracket 14, so that when the ear clip type Bluetooth headset needs to be repaired and maintained, only the upper cover 12 and the lower cover 13 need to be disassembled, and the components in the first clamping part 10 can be taken out through the fixing bracket 14, which is convenient for the replacement and maintenance of the components. At the same time, during the assembly process of the ear clip type Bluetooth headset, the above components and devices can be installed on the fixing bracket 14, and uniformly installed into the installation space enclosed by the upper cover 12 and the lower cover 13 through the fixing bracket 14, which reduces the assembly difficulty of the ear clip type Bluetooth headset and improves the assembly efficiency of the ear clip type Bluetooth headset.

[0102] Please refer to Figure 8-Figure 9In order to further reduce the difficulty of production and assembly of the ear clip type Bluetooth headset, the second clamping portion 20 is provided with a plug-in slot 22, and the rotating component 30 is at least partially plugged into the plug-in slot 22. In the embodiment where the rotating component 30 includes a first rotating member 31 and a second rotating member 32, the first end of the second rotating member 32 is plugged into the plug-in slot 22, and the first end of the second rotating member 32 extends out of the second clamping portion 20 through the notch of the plug-in slot 22, and rotates with the first rotating member 31. Here, the first end of the second rotating member 32 and the second clamping portion 20 can be integrally formed, that is, during the molding process of the second clamping portion 20 by injection molding, etc., the first end of the second rotating member 32 is fixed in the second clamping portion 20, or the first end of the second rotating member 32 can be connected to the second clamping portion 20 by a plug-in fit, which is convenient for the disassembly and assembly of the ear-clip type Bluetooth headset, so that the second rotating member 32 can be disassembled and separated from the first clamping portion 10 in the state of multiple second clamping portions 20, and the second rotating member 32 can be replaced, so that the rotating assembly 30 can be maintained in a state that meets the performance of the antenna radiator.
