Description

Technical Field

[0001] The present application relates to the technical field of wearable electronic devices, and in particular to a headset. Background Art

[0002] True wireless Bluetooth earphones are widely used in daily life due to their portability and ease of wearing. Early true wireless earphones were mostly in-ear or semi-in-ear styles. When worn, the earphones needed to be inserted into the ear canal for fixation, which would cause pressure and blockage on the wearer's ear canal, making it difficult for users to wear them for long periods of time. Therefore, ear clip earphones have gradually become a new product favored by people. However, existing ear clip designs have certain limitations. Specifically, ear clip earphones include a speaker compartment, a battery compartment, and an elastic connector connected between the speaker compartment and the battery compartment. The elastic connector is designed in a U-shape, with its two ends connected to the same side of the speaker compartment and the battery compartment. When worn, the speaker compartment is placed in the concha cavity, the elastic connector bypasses the auricle, and the battery compartment is located behind the ear. Therefore, the elastic connector protrudes a large distance relative to the side walls of the speaker compartment and the battery compartment, which in turn results in a large size of the entire earphone. The size of the charging compartment for storing the earphones also increases accordingly, resulting in the problem of poor portability of the earphones. Utility Model Content

[0028] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0029] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0030] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0031] True wireless Bluetooth earphones are widely used in daily life due to their portability and ease of wearing. Early true wireless earphones were mostly in-ear or semi-in-ear styles. When worn, the earphones needed to be inserted into the ear canal for fixation, which would cause pressure and blockage on the wearer's ear canal, making it difficult for users to wear them for long periods of time. Therefore, ear clip earphones have gradually become a new product favored by people. However, existing ear clip designs have certain limitations. Specifically, ear clip earphones include a speaker compartment, a battery compartment, and an elastic connector connected between the speaker compartment and the battery compartment. The elastic connector is designed in a U-shape, with its two ends connected to the same side of the speaker compartment and the battery compartment. When worn, the speaker compartment is placed in the concha cavity, the elastic connector bypasses the auricle, and the battery compartment is located behind the ear. Therefore, the elastic connector protrudes a large distance relative to the side walls of the speaker compartment and the battery compartment, which in turn results in a large size of the entire earphone. The size of the charging compartment for storing the earphones also increases accordingly, resulting in the problem of poor portability of the earphones.

[0032] In order to overcome the above technical problems, this embodiment provides an earphone, including a first earphone body 1, a second earphone body 2 and a flexible connecting arm 3, the flexible connecting arm 3 connecting the first earphone body 1 and the second earphone body 2. By redesigning the structure of the flexible connecting arm 3, while maintaining a reliable wearing function, the distance that the flexible connecting arm 3 protrudes relative to the first earphone body 1 and the second earphone body 2 in the idle state is effectively reduced, thereby achieving the purpose of improving the overall compactness of the entire earphone and reducing the size of the earphone.

[0033] In the specific structure of the earphone of this embodiment, refer to Figure 1-2 The flexible connecting arm 3 has a first connecting end 31 and a second connecting end 32 relative to each other, the first connecting end 31 is connected to the side of the first earphone body 1 away from the second earphone body 2, and the second connecting end 32 is connected to the side of the second earphone body 2 away from the first earphone body 1; the flexible connecting arm 3 has elastic deformation ability, and in the idle state, the side wall of the flexible connecting arm 3 is close to the first earphone body 1 and the second earphone body 2; in the wearing state, the flexible connecting arm 3 can be used to wrap around from the front side of the ear to the back side of the ear, so that the first earphone body 1 and the second earphone body 2 can be clamped and fixed from both sides of the ear respectively.

[0034] Among them, the first earphone body 1 and the second earphone body 2 share different functions. For example, the first earphone body 1 can be installed with a speaker, and the second earphone body 2 can be installed with a battery 23 and a main control board for control. The first earphone body 1 and the second earphone body 2 also need to be connected by a signal line, and the signal line can be hidden in the flexible connecting arm 3. In the idle state, that is, when not worn, the earphones are generally stored in the charging box. At this time, the flexible connecting arm 3 is close to the side walls of the first earphone body 1 and the second earphone body 2, so as to minimize the size of the entire earphone; in the wearing state, the first earphone body 1 is located in the concha cavity, and the second earphone body 2 is located behind the ear. The flexible connecting arm 3 bypasses the auricle, so that the earphones can be reliably clamped on the ear. Figure 8 Status shown.

[0035] In summary, based on the earphones of this embodiment, in the idle state, the flexible connecting arm 3 can be close to the first earphone body 1 and the second earphone body 2 under the action of its own elastic restoring force, so that the flexible connecting arm 3 does not protrude too much relative to the first earphone body 1 and the second earphone body 2, thereby effectively reducing the overall size of the entire earphone and improving the portability of the earphone. Importantly, the first connecting end 31 and the second connecting end 32 of the flexible connecting arm 3 are respectively connected to the two opposite sides of the first earphone body 1 and the second earphone body 2, so that the flexible connecting arm 3 can be close to the first earphone body 1 and the second earphone body 2 in the idle state. Moreover, since the two ends of the flexible connecting arm 3 are respectively connected to the two opposite sides of the first earphone body 1 and the second earphone body 2, that is, the flexible connecting arm 3 can cross and cover the first earphone body 1 and the second earphone body 2, the flexible connecting arm 3 has sufficient length to meet the requirement that the flexible connecting arm 3 can go from the front side of the auricle to the back side of the auricle when worn, thereby achieving a reliable wearing function while maintaining wearing comfort.

[0036] In one embodiment, combining Figure 2 and Figure 3 The flexible connecting arm 3 includes an intermediate connecting portion 33 and a first fitting portion 34 and a second fitting portion 35 respectively connected to the two ends of the intermediate connecting portion 33. The end of the first fitting portion 34 away from the intermediate connecting portion 33 is the first connecting end 31, and the end of the second fitting portion 35 away from the intermediate connecting portion 33 is the second connecting end 32. In the idle state, the first fitting portion 34 is close to the side wall of the first earphone body 1, and the second fitting portion 35 is close to the side wall of the second earphone body 2.

[0037] When the earphones are not in use, the first abutment portion 34 rests against the sidewall of the first earphone body 1, while the second abutment portion 35 rests against the sidewall of the second earphone body 2. This close fit helps reduce the overall size and makes the earphones more compact when stored. When the earphones are in use, the first abutment portion 34 and the second abutment portion 35 elastically deform with the wearing position of the earphones, ensuring that the connecting arm can smoothly move from the front to the back of the ear while maintaining a tight connection with the earphone body.

[0038] Among them, the middle connecting part 33 is generally set to be straight or slightly arc-shaped, and its two ends are connected to the first fitting part 34 and the second fitting part 35 to form the entire flexible connecting arm 3, while avoiding protruding too far relative to the side walls of the first earphone body 1 and the second earphone body 2.

[0039] In one embodiment, referring to Figure 3-4 The first earphone body 1 is provided with a first groove 1111 on a side corresponding to the first fitting part 34, and the second earphone body 2 is provided with a second groove 2111 on a side corresponding to the second fitting part 35. In the idle state, at least a portion of the first fitting part 34 is embedded in the first groove 1111, and at least a portion of the second fitting part 35 is embedded in the second groove 2111.

[0040] In the idle state, the first fitting portion 34 and the second fitting portion 35 will be at least partially embedded in the corresponding first groove 1111 and second groove 2111 due to the elasticity of their own materials. This design not only further reduces the overall size of the earphones, but also makes the connection between the connecting arm and the earphone body more stable.

[0041] In one embodiment, combined with Figure 7 The first earphone body 1 is provided with a first connecting hole 1112 on the side away from the second earphone body 2, and the first fitting part 34 is in the shape of a hook, which includes a first hook handle part 341 and a first curved hook part 342, and the two ends of the first hook handle part 341 are respectively connected to the intermediate connecting part 33 and the first curved hook part 342, and the end of the first curved hook part 342 away from the first hook handle part 341 is inserted into the first connecting hole 1112; the second earphone body 2 is provided with a second connecting hole 2112 on the side away from the first earphone body 1, and the second fitting part 35 is in the shape of a hook, which includes a second hook handle part 351 and a second curved hook part 352, and the two ends of the second hook handle part 351 are respectively connected to the intermediate connecting part 33 and the second curved hook part 352, and the end of the second curved hook part 352 away from the second hook handle part 351 is inserted into the second connecting hole 2112.

[0042] The first fitting portion 34 and the second fitting portion 35 are both configured in a hook shape, with the first curved hook portion 342 and the second curved hook portion 352 respectively inserted into the opposing first connection holes 1112 and the second connection holes 2112 to achieve a reliable connection with the first and second earphone bodies 1, 2. Simultaneously, the first hook handle portion 341 and the second hook handle portion 351 extend toward each other to connect to the ends of the intermediate connecting portion 33. Therefore, in addition to achieving the connection of the two ends of the flexible connecting arm 3 to the opposing sides of the first and second earphone bodies 1, 2, this solution also enables plug-in connection of the flexible connecting arm 3 with the first and second earphone bodies 1, 2. This plug-in connection structure effectively improves the reliability of the connection, thereby enhancing the durability of the earphones.

[0043] In one embodiment, referring to Figure 7 The flexible connecting arm 3 includes an elastic deformation member 36 and an outer rubber sleeve 37 , and the outer rubber sleeve 37 is covered on the outside of the elastic deformation member 36 .

[0044] The elastic deformable member 36 is the core part of the flexible connecting arm 3. It is responsible for providing the necessary elasticity and deformation ability to adapt to the different shapes of the earphones when they are worn and when they are idle. The material used for the elastic deformable member 36 usually has good resilience and fatigue resistance, and can maintain stable performance after multiple bending and stretching. The outer rubber sleeve 37 is a layer of material wrapped around the outside of the elastic deformable member 36. It mainly plays a role in protection and comfort. The rubber sleeve material is usually selected from soft, skin-friendly materials such as silicone or TPU. These materials can provide good touch and wearing comfort, while reducing the irritation and pressure of the earphones on the skin. The outer rubber sleeve 37 can also enhance the durability of the connecting arm, prevent the elastic deformable member 36 from being eroded and worn by the external environment, and thus extend the service life of the earphones.

[0045] In one embodiment, the elastic deformable member 36 is a memory metal strip.

[0046] The memory metal strip has a unique shape memory effect, that is, after being deformed by an external force, it can return to its original shape after the external force is removed. This property enables the memory metal strip, when used as an elastic deformable member 36, to adapt well to the shape changes of the headphones under different usage conditions and automatically return to a compact state when idle. The softness and good shape memory effect of the memory metal strip enable the flexible connecting arm 3 to better fit the user's ear shape when worn, reducing the sense of pressure and discomfort and improving wearing comfort. Therefore, the elasticity and toughness of the memory metal strip used in this embodiment make the flexible connecting arm 3 more stable during wearing and less likely to fall off or loosen due to external forces, thereby improving the safety of the headphones.

[0047] Preferably, the memory metal strip is nickel-titanium alloy.

[0048] In one embodiment, two elastic deformation members 36 are provided in parallel, and the outer rubber sleeve covers the two elastic deformation members 36 at the same time.

[0049] The number of elastic deformation members 36 is set to two, and they are arranged in parallel, so that when the flexible connecting arm 3 is subjected to external force, the stress can be dispersed, reducing the burden of the single elastic deformation member 36, thereby improving the overall stability and durability.

[0050] In one embodiment, referring to Figure 3-4 The first earphone body 1 includes a first shell 11, and the second earphone body 2 includes a second shell 21. The first shell 11 and the second shell 21 are both flat cylindrical structures, and the central axes of the first shell 11 and the second shell 21 are arranged in parallel.

[0051] Specifically, the oblate cylindrical structure can be either a quasi-cylindrical or a prism. Its oblate shape means its axial height is less than its radial width. The central axes of the first and second shells 11, 21 are parallel, so the overall thickness of the earphones is equal to the thickness of either the first shell 11 or the second shell 21. Since the oblate cylindrical structures of the first and second shells 11, 21 are inherently relatively thin, the earphones of this embodiment have an overall low thickness, making them easier to store and carry.

[0052] Preferably, the thickness of the first shell 11 and the second shell 21 is less than 6 mm. More preferably, the thickness of the first shell 11 and the second shell 21 is less than 5 mm.

[0053] In one embodiment, referring to Figure 5 The first shell 11 includes a first barrel 111 and a first top cover 112 and a first bottom cover 113 respectively covering the two ends of the first barrel 111; the second earphone body 2 includes a second shell 21, and the second shell 21 includes a second barrel 211 and a second top cover 212 and a second bottom cover 213 respectively covering the two ends of the second barrel 211; the central axes of the first barrel 111 and the second barrel 211 are arranged in parallel, the first connecting end 31 is connected to the side of the first barrel 111 away from the second barrel 211, and the second connecting end 32 is connected to the side of the second barrel 211 away from the first barrel 111.

[0054] The first shell 11 and the second shell 21 are respectively configured as a structure composed of a cylinder, a top cover and a bottom cover, so as to facilitate installation of internal components into the first shell 11 and the second shell 21 during assembly.

[0055] In one embodiment, a speaker 13 is installed in the first shell 11 , and a sound outlet 1113 is provided on a side of the first cylinder 111 away from the flexible connecting arm 3 ; a battery 23 and a main control board are installed in the second shell 21 .

[0056] A speaker 13 is installed in the first shell 11. The side of the first shell 11 away from the flexible connecting arm 3 is the side facing the ear canal when worn. The sound hole 1113 is set on this side to provide the best sound effect for the user.

[0057] A battery 23 is installed in the second shell 21 for power supply. To facilitate charging, a charging hole is provided on one side of the second shell 21. The charging contacts 22 in the second shell 21 are aligned with the charging hole to facilitate connection with an external charger for charging.

[0058] In one embodiment, a detection sensor is provided in the second housing 21 , and the detection sensor is used to detect the usage status of the earphone.

[0059] Specifically, a detection sensor is set up to detect the usage status of the headphones, which can realize the function of adaptively controlling the operation of the headphones based on the detection results. For example, when it is detected that the headphones are being worn, the playback can be automatically started; when it is detected that the headphones are not in use, the playback can be automatically paused or turned off.

[0060] Optionally, the detection sensor is a capacitive sensor, which determines whether the wearer is wearing the device by detecting the capacitance value of the human body. The judgment standard is that if the capacitance value detected exceeds a set threshold, it is considered that the wearer is wearing the device.

[0061] Alternatively, the detection sensor is an optical sensor that detects whether the earphones fit the skin by emitting laser and receiving reflected light. If the reflected light signal exceeds a set value, it is considered that the earphones are being worn.

[0062] Alternatively, the detection sensor is specifically used to detect whether the earphones are out of the box. If they are out of the box, they are judged to be in the wearing state, and if they are stored in the box, they are judged to be in the idle state. In implementation, the earphones are connected to the charging box via the charging port. If the charging port is disconnected, the earphones are considered to be out of the box. The charging port status is detected by a built-in switch or magnetic sensor.
