Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology. Background Technology

[0002] Current Bluetooth headphones generally use a fixed earcup design, and the sound-generating components of the headband cannot be detached, limiting their usability. Traditional solutions have the following drawbacks:

[0003] Limited usage modes: Users cannot flexibly switch between single-ear and dual-ear modes according to their needs. For example, in scenarios that require environmental sound perception (such as outdoor sports and meeting communication), wearing closed-back dual-ear headphones may pose safety hazards or communication barriers, while existing technologies cannot provide a lightweight option for single-ear use.

[0004] Wearing stability issues: Forcibly removing one earcup may cause the center of gravity of the headband assembly to shift, disrupting the mechanical balance, causing the headphones to slip or tilt, affecting the user experience.

[0005] Therefore, there is room for improvement in existing over-ear Bluetooth headphones. Utility Model Content

[0006] The technical problem solved by this disclosure is to provide a Bluetooth headset that can switch between single-ear and dual-ear modes.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a Bluetooth headset with switchable single and dual earphones, the headset having a headband assembly and a headphone mainboard assembly, the headset being configured with a first earcup sound-emitting assembly, a single earcup clamping assembly and a second earcup sound-emitting assembly; the first earcup sound-emitting assembly and the single earcup clamping assembly are switchably connected to the first end of the headband assembly; wherein, when the first earcup sound-emitting assembly is connected to the first end of the headband assembly, it is simultaneously electrically connected to the headphone mainboard assembly; the second earcup sound-emitting assembly is connected to the second end of the headband assembly, and the second earcup sound-emitting assembly is electrically connected to the headphone mainboard assembly.

[0008] As described above, the single / dual ear switchable Bluetooth headset has a first earcup sound-emitting component with a first connecting part, a single earcup clamping component with a second connecting part, and a first end of the headband component with a docking part; both the first connecting part and the second connecting part are detachably connected to the docking part to switch between installing the first earcup sound-emitting component and the single earcup clamping component at the first end of the headband component.

[0009] As described above, the single / dual ear switchable Bluetooth headset has a first connector section, a second connector section, and a docking part with a docking cavity. Both the first connector section and the second connector section can be adapted to and plugged into the docking cavity.

[0010] As described above, in the switchable single / dual ear Bluetooth headset, both the first and second plug sections are reinforcedly connected to the plug cavity via a snap-fit ​​structure.

[0011] As described above, the Bluetooth headset with switchable single and dual earbuds has a slot on both the first and second plug sections, and a toggle switch is provided at the plug cavity. The toggle switch can be slid to adjust its locking with the slot.

[0012] As described above, the single / dual ear switchable Bluetooth headset has a slot with a clearance groove and a locking groove. The locking groove has a release end and a locking end. When the first or second plug segment is inserted into the plug cavity, the clearance groove avoids the toggle switch so that the toggle switch reaches the locking groove and is operated to move from the release end into the locking end, locking the first or second plug segment in the plug cavity.

[0013] As described above, in a switchable single / dual ear Bluetooth headset, the recess extends longitudinally, the locking groove extends laterally, and the release end of the locking groove is connected to the end of the recess.

[0014] As described above, the single / dual ear switchable Bluetooth headset has an electrical connection contact point in the first plug segment and an electrical connection spring piece connected to the headset motherboard assembly in the plug cavity. When the first plug segment is inserted into the plug cavity, the electrical connection contact point is electrically connected to the electrical connection spring piece.

[0015] As described above, the single-ear / dual-ear switchable Bluetooth headset has a housing with a pad installed on the inner side of the housing.

[0016] As described above, in a switchable single / dual ear Bluetooth headset, the second earcup sound-emitting component can slide and extend relative to the headband component.

[0017] The beneficial effects of this disclosure are as follows: The Bluetooth headphones of the present invention achieve the following technical advantages through the coordinated design of the detachable earcup sound-generating component and the single earcup clamping component:

[0018] Multi-scenario adaptability: Users can flexibly switch between single-ear and dual-ear modes. Single-ear mode can meet the needs of outdoor scenarios where environmental awareness is required or for long-term calls. For example, single-ear mode can improve safety when driving or walking.

[0019] Clamping optimization: By configuring a single earcup clamping component, after the first earcup sound-generating component is removed and installed on the headband component, it is clamped and fixed to the head to prevent it from falling off.

[0020] Through the above innovations, this invention resolves the contradiction between flexibility and stability in traditional headphones, realizing the user value of "one device for multiple uses". Attached Figure Description

[0035] See appendix Figure 1-7 The image shows a Bluetooth headset with switchable single / dual earphone functionality. The headset includes a headband assembly 3 and a headphone mainboard assembly. The headset is equipped with a first earcup sound-emitting assembly 1, a single earcup clamping assembly 4, and a second earcup sound-emitting assembly 2. The first earcup sound-emitting assembly 1 and the single earcup clamping assembly 4 can be switched to be connected to the first end 301 of the headband assembly 3. When the first earcup sound-emitting assembly 1 is connected to the first end 301 of the headband assembly 3, the first earcup sound-emitting assembly 1 is also electrically connected to the headphone mainboard assembly. The second earcup sound-emitting assembly 2 is connected to the second end 302 of the headband assembly 3, and the second earcup sound-emitting assembly 2 is electrically connected to the headphone mainboard assembly.

[0036] The headband assembly 3 is arc-shaped to fit the shape of the top of the head. Both ends of the headband assembly 3 extend from the sides of the head to the two ears, namely the first end 301 and the second end 302. The first end 301 of the headband assembly 3 is equipped with a first earmuff sound-emitting assembly 1 and a single earmuff clamping assembly 4. The user can choose to install one of the two according to actual needs. The second end 302 of the headband assembly 3 is equipped with a second earmuff sound-emitting assembly 2.

[0037] When the first earcup sound-generating component 1 is installed on the first end 301, it forms a binaural mode with the second earcup sound-generating component 2. Both earcup sound-generating components are electrically connected to the headphone mainboard component for audio playback. When the first end 301 is installed with the single earcup clamping component 4, the headphones are in monophonic mode. The user can only listen to audio content through the second earcup sound-generating component 2. The single earcup clamping component 4 has a certain clamping force, which can ensure the stability of the user's wearing in monophonic mode, so that the user can use it in scenarios where they need to receive external sounds and headphone sounds simultaneously.

[0038] Preferably, the single ear cup clamping assembly 4 has a housing 402, and a soft pad 403 is installed on the inner side of the housing 402. In the single ear state, the single ear clamping assembly contacts the head through the soft pad 403, providing a comfortable feel.

[0039] The headphone mainboard assembly can be installed in the headband assembly 3 or inside the housing of the second earcup sound-emitting assembly 2. It typically includes a control mainboard, Bluetooth unit, and power supply components. The first earcup sound-emitting assembly 1 and the second earcup sound-emitting assembly 2 both include speakers to receive signals from the headphone mainboard assembly and play sound.

[0040] In some embodiments, the first earmuff sound-generating assembly 1 is provided with a first connecting portion 101, the single earmuff clamping assembly 4 is provided with a second connecting portion 401, and the first end 301 of the headband assembly 3 is provided with a docking portion; both the first connecting portion 101 and the second connecting portion 401 are detachably coupled with the docking portion to switch the installation of the first earmuff sound-generating assembly 1 and the single earmuff clamping assembly 4 on the first end 301 of the headband assembly 3.

[0041] The first earcup sound-generating assembly 1 is detachably connected to the first end 301 of the headband assembly 3 via the first connecting part 101, and the single earcup clamping assembly 4 is detachably connected to the first end 301 of the headband assembly 3 via the second connecting part 401. Users can choose between the two according to their needs. Generally, the first connecting part 101 and the second connecting part 401 are provided with the same connection structure, while the mating part is provided with a matching mating structure. For example, the first connecting part 101 and the second connecting part 401 are both connected to the mating part by a tight-fitting insert method, or the first connecting part 101 and the second connecting part 401 are both connected to the mating part by a threaded structure.

[0042] Preferably, the first connecting part 101 has a first insertion segment, the second connecting part 401 has a second insertion segment, and the mating part has an insertion cavity 304. Both the first and second insertion segments can be fitted into the insertion cavity 304. For example, both the first and second insertion segments are configured as flat columns, and the insertion cavity 304 has a flat cavity inside. By tightly fitting the first or second insertion segment into the insertion cavity 304, the connection between the first earmuff sound-generating assembly 1 or the single earmuff clamping assembly 4 and the headband assembly 3 can be realized. When switching is required, force can be applied to pull out and install another assembly.

[0043] To enhance the stability of the connection between the first earmuff sound-generating assembly 1, the single earmuff clamping assembly 4, and the headband assembly 3, both the first and second insertion sections are reinforced with the insertion cavity 304 through a snap-fit ​​structure.

[0044] There are various implementations of the snap-fit ​​structure. For example, in some embodiments, both the first and second insertion segments are provided with slots, and a toggle switch 303 is disposed at the insertion cavity 304. Operating the toggle switch 303 allows for adjustment of its locking with the slots. When the first or second insertion segment is inserted into the insertion cavity 304, the toggle switch 303 is mounted on the side wall of the insertion cavity 304, that is, at a position on the housing of the head beam assembly 3 corresponding to the insertion cavity 304. The toggle switch 303 engages with the slots, and applying force to slide the toggle switch 303 to the locked position with the slots prevents the first or second insertion segment from detaching arbitrarily. When disassembly is required, operating the toggle switch 303 to the unlocked position releases the lock on the slots, allowing the first or second insertion segment to be pulled out of the insertion cavity 304.

[0045] Specifically, the slot has a clearance groove 102 and a locking groove, and the locking groove has a release end 103 and a locking end 104; when the first or second insertion segment is inserted into the insertion cavity 304, the clearance groove 102 avoids the toggle switch 303, the toggle switch 303 reaches the locking groove, and is operated to enter the locking end 104 through the release end 103, so as to lock the first or second insertion segment in the insertion cavity 304.

[0046] The recessed groove 102 extends longitudinally, consistent with the movement direction of the first and second insertion sections entering and exiting the insertion cavity 304. The locking groove extends laterally, with its release end 103 connecting to the end of the recessed groove 102, forming an L-shape. When the first and second insertion sections are assembled with the insertion cavity 304, the recessed groove 102 avoids the toggle switch 303. The toggle switch 303 reaches the locking groove, and by operating the toggle switch 303, it slides laterally, moving from the release end 103 to the locking end 104, creating interference to lock with the slot. Neither the first nor the second insertion section can be arbitrarily pulled out. To unlock, the toggle switch 303 is operated to move back to the release end 103 of the locking groove, and then the first or second insertion section is pulled out. At this time, the toggle switch 303 disengages along the recessed groove 102, releasing the lock.

[0047] Specifically, a transverse strip groove is provided on the side wall of the insertion cavity 304. The toggle switch 303 is installed in the strip groove. The toggle switch 303 is located in the insertion cavity 304 and the lever exposed through the strip groove forms the operation. The lever slides along the strip groove and enters the locking end 104 from the release end 103, thereby achieving locking.

[0048] In some embodiments, the first plug segment is provided with an electrical contact point 105, and the plug cavity 304 is provided with an electrical connection spring 305 connected to the headphone mainboard assembly. When the first plug segment is inserted into the plug cavity 304, the electrical contact point 105 and the electrical connection spring 305 are electrically connected. The plug cavity 304 uses an elastic electrical connection spring 305. When the first plug segment is inserted into the cavity, the electrical contact point 105 and the electrical connection spring 305 maintain a tight and stable electrical connection, so that the first earcup sound-generating assembly 1 and the headphone mainboard assembly can achieve signal connection for audio content playback.

[0049] In some embodiments, the second earcup sound-emitting component 2 can slide telescopically relative to the headband component 3. The second earcup sound-emitting component 2 is slidably mounted on the second end 302 of the headband component 3, and the length of the headband component 3 can be adjusted by sliding telescopically to accommodate users with different head shapes.

[0050] In summary, the improved single / dual ear switchable Bluetooth headphones, through the collaborative design of the detachable earcup sound-generating component and the single earcup clamping component, allow users to flexibly switch between single and dual ear modes, making the headphones better suited for different usage scenarios.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, this utility model can have various modifications, combinations, and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
