Description
Technical Field
[0001] The utility model relates to the technical field of wireless earphone design, in particular to a Bluetooth earphone. Background Art
[0002] A Bluetooth earphone is a device that establishes data transmission with a sound source device through Bluetooth communication to achieve audio playback. Compared with traditional wired earphones, Bluetooth earphones are free from the restraint of wires, are more flexible and convenient to use, and are simple and generous. Since Bluetooth earphones abandon wires, they need to be equipped with an internal battery to supply power. And the volume of Bluetooth earphones is generally relatively small, so the capacity of the battery that can be accommodated is also very small. Therefore, Bluetooth earphones need to be charged through a supporting charging case. Generally, metal terminals extending to the outside are provided in Bluetooth earphones. When the Bluetooth earphone is placed in the receiving groove of the charging case, the metal terminals are docked with the charging pins in the charging case to establish an electrical connection.
[0003] The disadvantages of traditional Bluetooth earphones are as follows: the metal terminals of Bluetooth earphones are all exposed and are easily eroded by environmental dust and liquids (for example, adhered to by human sweat). After long-term use, problems such as dust accumulation and rusting are likely to occur on the metal terminals, resulting in poor electrical contact during charging, making the Bluetooth earphone unable to be charged. Summary of the Utility Model
[0004] Based on this, the utility model provides a Bluetooth earphone, in which a slidable shielding component is arranged in the receiving cavity of the housing, and an elastic shielding piece on the shielding component is used to block the charging jack, so as to realize the hidden protection of the metal terminals, make the metal terminals not easily eroded by environmental dust and liquids, reduce the risk of dust accumulation and rusting, avoid poor electrical contact during charging, and improve the reliability of charging.
[0005] A Bluetooth earphone includes:

[0008] A shielding component installed on the housing; the shielding component includes: a driven rod slidably connected to the back cover, a spring sleeved on the driven rod, a first shielding piece connected to the driven rod, and a second shielding piece connected to the driven rod; the driven rod extends towards the avoidance hole; the spring is used to drive the driven rod to reset; both the first shielding piece and the second shielding piece are arc-shaped elastic pieces and are symmetrically arranged with respect to the midline of the U-shaped chute; both the first shielding piece and the second shielding piece are slidably arranged in the U-shaped chute to block the charging jack.
[0009] For the above Bluetooth headset, when the Bluetooth headset is outside the charging case, the driven rod of the shielding component extends into the avoidance hole under the action of the spring to block the avoidance hole. At this time, driven by the driven rod, the first shielding piece and the second shielding piece, both of which are elastic pieces, extend forward along the U-shaped chute and block the charging jack, so that the metal terminals are hidden in the receiving cavity of the housing. When the Bluetooth headset is placed in the charging case for charging, the driven rod contacts the charging case and retracts, thereby driving the first shielding piece and the second shielding piece to retreat, so that the charging jack is restored to be unobstructed, and the charging pins in the charging case are docked with the metal terminals on the control board. Through the above design, a slidable shielding component is arranged in the receiving cavity of the housing, and the elastic shielding pieces on the shielding component are used to block the charging jack, so as to realize the hidden protection of the metal terminals, making the metal terminals not easily eroded by the dust and liquid in the environment, reducing the risk of dust accumulation and rust, avoiding poor electrical contact during charging, and improving the charging reliability.
[0010] In one embodiment, the outer end of the driven rod is retracted relative to the outer end of the avoidance hole. When the Bluetooth headset is placed in the charging case, the retracted driven rod is further pushed into the housing by the ejector rod arranged in the charging case. When the Bluetooth headset is outside the charging case, the retracted setting of the driven rod makes its concealment better, improves the aesthetics, and reduces the probability of being accidentally touched.
[0011] In one embodiment, the outer end of the driven rod protrudes relative to the outer end of the avoidance hole. When the Bluetooth headset is placed in the charging case, the protruding driven rod is pushed into the housing by the inner wall of the charging case, making the driving of the driven rod more sensitive and convenient, and the structure is simple.
[0012] In one embodiment, the back cover is provided with a light-transmitting area, and the control board is also provided with an indicator light close to the light-transmitting area.

[0038] As Figures 1 to 10 shown, it is a Bluetooth headset 100 of an embodiment of the present utility model.
[0039] As Figures 1 to 3 shown, the Bluetooth headset 100 includes: a housing 10, an electronic component 20 housed in the housing 10, and a shielding component 30 mounted on the housing 10. Among them, the housing 10 is used to house and protect the electronic component 20. The electronic component 20 is used to implement functions such as signal transmission and audio playback. The shielding component 30 is used to protect the electronic component 20.
[0040] As described below, in conjunction with Figures 1 to 10 , the above-mentioned Bluetooth headset 100 will be further described.
[0041] As Figure 3 shown, the housing 10 includes: a main housing 11, a face cover 12 connected to the main housing 11, and a back cover 13 connected to the main housing 11. In conjunction with Figure 2 shown, the main housing 11, the face cover 12, and the back cover 13 enclose to form a storage cavity 14. As Figure 6 shown, one end of the main housing 11 is provided with a U-shaped chute 111 and a charging jack 112. Among them, the U-shaped chute 111 is opened on the inner side wall of the end of the main housing 11, and the charging jack 112 penetrates through the U-shaped chute 111. As Figure 7 shown, the back cover 13 is provided with an avoidance hole 131 parallel to the charging jack 112.
[0042] As Figure 4 shown, the electronic component 20 includes: a control board 21 housed in the storage cavity 14, a battery 22 connected to the control board 21, and a speaker 23 connected to the control board 21. Among them, the control board 21 is located between the main housing 11 and the back cover 13, and the control board 21 is provided with a Bluetooth communication module, an audio signal processing circuit, and a charging circuit (not shown in the figure). As Figure 5 shown, the control board 21 is provided with a metal terminal 211 extending towards the charging jack 112. In this embodiment, the metal terminal 211 is one of the necessary components for realizing the charging function of the battery 22. At the same time, the number of the metal terminals 211 is two and both are cylindrical. As Figure 4 shown, the speaker 23 is arranged towards the face cover 12.
[0043] In addition, as Figure 4 shown, a microphone 213 is also provided on the control board 21. Correspondingly, as Figure 6 shown, a sound receiving hole 113 is opened on the main housing 11. It should be noted that in this embodiment, the sound outlet hole is arranged on the face cover 12.
[0044] In order to improve the aesthetics and interest of the product, in this embodiment, as Figure 7 shown, the back cover 13 is provided with a light-transmitting area 132. Correspondingly, as Figure 4 shown, the control board 21 is also provided with an indicator light 212 arranged close to the light-transmitting area 132. The built-in indicator light 212 can prevent the indicator light 212 from being collided by external objects, and when the indicator light 212 is in a non-lighting state, the user cannot know the position of the indicator light 212 by the naked eye, which is beautiful and interesting
[0045] As Figure 9As shown, the shielding component 30 includes: a driven rod 31 slidably connected to the back cover 13, a spring 32 sleeved on the driven rod 31, a first shielding piece 33 connected to the driven rod 31, and a second shielding piece 34 connected to the driven rod 31. As Figure 8 shown, the driven rod 31 extends towards the avoidance hole 131. The spring 32 is used to drive the driven rod 31 to reset. Combining Figure 9 and Figure 10 shown, both the first shielding piece 33 and the second shielding piece 34 are arc-shaped elastic pieces and are symmetrically arranged with respect to the midline of the U-shaped chute 111. As Figure 5 shown, both the first shielding piece 33 and the second shielding piece 34 are slidably arranged in the U-shaped chute 111 to block the charging jack 112. In this solution, the reason why both the first shielding piece 33 and the second shielding piece 34 adopt arc-shaped elastic pieces is that both the first shielding piece 33 and the second shielding piece 34 need to slide in the U-shaped chute 111 and can deform during the sliding process to adapt to the shapes of the straight and curved segments of the U-shaped chute 111.
[0046] In this solution, the outer end of the driven rod 31 relative to the outer end of the avoidance hole 131 can be retracted or protruded, and both have their own advantages.
[0047] For example, as Figure 2 and Figure 3 shown, in this embodiment, the outer end of the driven rod 31 is retracted relative to the outer end of the avoidance hole 131. When the Bluetooth headset 100 is placed in the charging bin, the retracted driven rod 31 is further pushed into the housing 10 by the ejector rod provided in the charging bin. When the Bluetooth headset 100 is outside the charging bin, the retracted setting of the driven rod 31 makes it more concealed, improves the aesthetics, and reduces the probability of being accidentally touched.
[0048] Another example is that in other embodiments, the outer end of the driven rod 31 protrudes relative to the outer end of the avoidance hole 131. When the Bluetooth headset 100 is placed in the charging bin, the protruding driven rod 31 is pushed into the housing 10 by the inner wall of the charging bin, making the driving of the driven rod 31 more sensitive and convenient, and the structure is simple.
[0049] In order to improve the stability and accuracy of the movement of the driven rod 31, the following improvements can also be made.
[0050] For example, combining Figure 7 and Figure 8As shown, in this embodiment, the back cover 13 is provided with a slideway 133 that is linearly communicated with the avoidance hole 131. The back cover 13 is further provided with a limiting block 134. The driven rod 31 is inserted through the limiting block 134 and slidably mounted on the slideway 133. One end of the spring 32 abuts against the limiting block 134, and the other end of the spring 32 abuts against the front end of the driven rod 31. The movement track of the driven rod 31 can be effectively limited by the slideway 133 and the limiting block 134, and the structure is simple and effective.
[0051] Further, as Figure 7 and Figure 8 shown, in this embodiment, a stop block 311 is provided at the tail end of the driven rod 31. The stop block 311 is located on the side of the limiting block 134 opposite to the spring 32. The stop block 311 can prevent the driven rod 31 from detaching from the limiting block 134, and the structure is simple and effective.
[0052] For another example, as Figure 9 and Figure 10 shown, in this embodiment, a T-shaped adapter block 312 is provided at the front end of the driven rod 31. One end of the adapter block 312 is connected to the tail end of the first shielding piece 33, and the other end of the adapter block 312 is connected to the tail end of the second shielding piece 34. The connection between the driven rod 31 and the first shielding piece 33 and the second shielding piece 34 is realized by using the T-shaped adapter block 312, so that the force balance of the driven rod 31 is better, it is not easy to deflect, and the movement stability is good.
[0053] Further, in this embodiment, the adapter block 312 is respectively clamped to the first shielding piece 33 and the second shielding piece 34. The clamping installation method is convenient for replacing parts and reduces the difficulty of disassembly, assembly and maintenance. In other embodiments, the adapter block 312 can also be connected to the first shielding piece 33 and the second shielding piece 34 by means of glue, rivets, welding, etc.
[0054] Brief description of the working principle:
[0055] When the Bluetooth headset 100 is outside the charging case, as Figure 2 and Figure 3 shown, under the action of the spring 32, the driven rod 31 of the shielding assembly 30 extends into the avoidance hole 131 to block the avoidance hole 131. At this time, driven by the driven rod 31, the first shielding piece 33 and the second shielding piece 34, both of which are elastic pieces, extend forward along the U-shaped chute 111 and block the charging jack 112 (that is, the front end of the shielding piece enters the curved section of the U-shaped chute 111 and blocks the charging jack 112), so that the metal terminal 211 is hidden in the receiving cavity 14 of the housing 10.
[0056] When the Bluetooth headset 100 is placed in the charging compartment for charging, the driven rod 31 contacts the charging compartment and retracts (correspondingly, the spring 32 is compressed), thereby driving the first shielding piece 33 and the second shielding piece 34 to retreat, so that the charging socket 112 is restored to be unobstructed (that is, the front end of the shielding piece retreats to the straight section of the U-shaped slide 111 and is staggered with the charging socket 112), so that the charging pins in the charging compartment are connected with the metal terminals 211 on the control board 21.
[0057] The above-mentioned Bluetooth headset 100 is provided with a slidable shielding component 30 in the storage cavity 14 of the housing 10, and the charging jack 112 is blocked by an elastic shielding sheet on the shielding component 30, thereby realizing hidden protection of the metal terminal 211, making it difficult for the metal terminal 211 to be corroded by dust and liquid in the environment, reducing the risk of dust accumulation and rust, avoiding poor electrical contact during charging, and improving the reliability of charging.
[0058] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0059] The above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
