[0028] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0029] refer to Figure 1 and Figure 6 According to a preferred embodiment of the present invention, a rollable Bluetooth headset includes a speaker compartment 1, a battery compartment 2, and an elastic bridge 3 connecting the speaker compartment 1 and the battery compartment 2.

[0030] The flexible bridge 3 employs a flexible structure, allowing the earphones to have both a retracted and an extended state. In the retracted state, the flexible bridge 3 wraps around the speaker compartment 1, which fits snugly against the battery compartment 2, making the earphones more compact and portable. In the extended state, the speaker compartment 1 separates from the battery compartment 2, and the speaker compartment 1, battery compartment 2, and flexible bridge 3 work together to form a "C"-shaped or C-like ear-clamping space, which can hold the user's earlobe during wear. Furthermore, because the flexible bridge 3 is extendable and retractable, the clamping force between the speaker compartment 1 and the battery compartment 2 can be adjusted, ensuring the user doesn't experience excessive clamping force or that the earphones won't fall out due to insufficient clamping force. The length of the flexible bridge 3 can also be adjusted to change the wearing position, bringing the speaker compartment 1 closer to the ear canal for receiving lower sound pressure levels and improving the user experience.

[0031] The speaker compartment 1 and the flexible bridge 3 can be integrated into a single structure using dual-material injection molding of hard and soft plastics, combining the two materials to enhance grip, impact resistance, and aesthetics. The battery compartment 2 and the flexible bridge 3 can be bonded together, simplifying earphone assembly and ensuring the product's integrity and stability.

[0032] The speaker compartment 1 houses a speaker 4, and provides an acoustic cavity and a sound outlet 12 for the speaker 4. The speaker 4 is housed within the acoustic cavity, and the sound outlet 12 is located at the front end of the speaker compartment 1 and faces the concha when worn. This avoids hearing damage caused by the earphone blocking the ear canal, while its proximity to the ear canal allows for amplification through the reflection of sound from the concha, resulting in superior sound quality and an enhanced user experience. The sound outlet 12 is coupled to the diaphragm of the speaker 4 through the acoustic cavity, and the sound emitted by the diaphragm vibration is transmitted outward through the acoustic cavity and the sound outlet 12.

[0033] From an ergonomic perspective, to enhance user comfort when wearing headphones, the elastic bridge 3 supports the speaker housing 1 to be located entirely or partially within the concha cavity. Alternatively, from a sound quality perspective, a larger speaker 4 is required. Optionally, the cross-sectional area of ​​the speaker 4 can be circular with a diameter of 10mm-18mm, or it can be non-circular, including but not limited to rectangular, racetrack-shaped, or elliptical shapes.

[0034] The speaker compartment 1 has a storage slot on its outer surface. When the earphone is in the retracted state, the elastic bridge 3 is housed in the storage slot, making the earphone smaller and easier to carry.

[0035] A sound vent 11 is provided on the speaker cavity 1, and the sound vent 11 is located in the speaker cavity 1 away from the ear clip space. By providing the sound vent 11, the sound quality can be effectively improved. Positioning the sound vent 11 away from the ear clip space prevents the ear from blocking the sound vent 11 during wear, thus avoiding the failure to improve sound quality. Preferably, the sound vent 11 is located at the rear end of the speaker cavity 1, preventing the sound vent 11 from being blocked while achieving optimal sound quality improvement. Furthermore, a waterproof and breathable membrane can be provided at the sound vent 11 to give the sound vent 11 better waterproof performance.

[0036] The speaker compartment 1 also houses a microphone 10 for calls. The microphone 10 is a front-facing microphone that picks up external sounds through a pickup hole on the surface of the speaker compartment 1. This pickup hole is positioned close to the edge of the speaker compartment 1's housing relative to the vent hole 11. This placement of the pickup hole near the user's mouth allows for better sound pickup. Furthermore, the pickup hole and the sound outlet hole 12 are positioned opposite each other, on opposite sides of the speaker compartment 1, which helps prevent feedback and improves the headset's interactivity and user experience.

[0037] The battery compartment 2 houses the mainboard (not shown), battery 8, and control buttons 6. Speaker 4, control buttons 6, battery 8, and microphone 10 are electrically connected to the mainboard. Battery 8 provides power to the headset, and control buttons 6 control the headset's functions, such as answering calls, playing music, and adjusting volume. Control methods include touch, swipe, tap, and press, among others. It is understood that the mainboard could also be located in speaker compartment 1; the specific arrangement of the mainboard can be determined according to actual needs.

[0038] The battery compartment 2 also houses a charging pin 7, which is electrically connected to the motherboard. Charging pin 7 is used to charge the battery 8. The control button 6 and charging pin 7 are positioned opposite each other, such as... Figure 4 As shown, the control button 6 and charging feet 7 are respectively located on the upper and lower sides of the battery compartment 2. The control button 6 is located on the upper surface of the battery compartment 2 and has an overall curved cylindrical structure, which is convenient for users to press and pinch. The charging feet 7 are located on the lower surface of the battery compartment 2, opposite to the control button 6, which makes efficient use of the space in the battery compartment 2. The lower surface is either flat or concave, which makes the connection between the earphone and the charging base more reliable. When there is sweat or other liquid on the earphone, the liquid can be distributed in the circular area of ​​the battery compartment 2, that is, around the charging feet 7, thereby reducing the corrosion of the charging feet 7 by sweat and improving the durability of the earphone.

[0039] The center line connecting the control button 6 and the charging foot 7 is perpendicular to the center line connecting the battery 8 and the speaker 4, which allows for a tight fit between the speaker compartment 1 and the battery compartment 2, reducing the size of the earphones and improving aesthetics and ease of use.

[0040] To ensure wearing comfort and minimize the space occupied when the earphones are not worn, the battery case 2 has a circular cross-sectional shape with a diameter of 12mm-16mm. It is understood that the cross-sectional shape of the battery case 2 can also be non-circular, including but not limited to rectangular, racetrack-shaped, or elliptical shapes.

[0041] An electrical connector 9 is installed inside the flexible bridge 3. The main board and the speaker 4 are electrically connected through the electrical connector 9. The electrical connector 9 can be a flexible circuit board, wire, etc., and is not limited here.

[0042] The elastic bridge 3 may be partially or entirely a flexible, stretchable structure, allowing it to extend, contract, or deform to support the earphones on ears of different sizes and provide varying clamping forces. Optionally, the elastic bridge 3 may be made of a material that can elastically deform after molding, such as thermoplastic plastics or rubber with certain plasticity and elasticity, capable of deforming under external force and returning to its original shape when the force is removed.

[0043] When the flexible bridge 3 is extended, its length ranges from 31.4mm to 56.5mm, a length that will not affect the wearing experience or comfort. When the flexible bridge 3 is retracted, the battery compartment 2 and the charging compartment 2 fit tightly together, minimizing the size of the earphones.

[0044] The elastic bridge 3 can be equipped with springs or spring bars, and users can set corresponding structures in the elastic bridge 3 according to bending requirements. In a preferred embodiment, the elastic bridge 3 is provided with a memory metal sheet 5. The elastic deformation of the memory metal sheet 5 allows the earphone to be better clamped on the auricle. At the same time, the memory metal sheet 5 can improve the elastic deformation performance of the elastic bridge 3 and increase the clamping force of the earphone.

[0045] The shape memory sheet 5 has a shape memory effect. The material can be selected from one or more materials such as carbon spring steel, low manganese spring steel, silicon manganese spring steel, stainless steel, elastic copper alloy, nickel-titanium alloy, gold-cadmium alloy, and indium-thallium alloy. Users can select materials to make shape memory sheet 5 according to the deformation characteristics required, and there are no restrictions.

[0046] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
