Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and in particular, to a headphone assembly. Background Art

[0002] With the development of True Wireless Stereo (TWS) headphones, various TWS headphones have emerged in an endless stream. One common type is the rod-shaped TWS headphone, whose charging method is that the handle rod is vertically inserted into the profiling groove of the charging case, and the charging pins are arranged at the bottom of the headphone. Another type is that the headphone lies flat in the charging case, and the charging pins are arranged at the head of the headphone. Conductive parts in the charging case are in elastic contact with the metal pins of the headphone for charging.

[0003] However, since the charging pins of the headphone and the conductive parts in the headphone case need to be in contact for a long time, this causes the charging pins of the headphone to be easily worn, resulting in poor contact between the headphone and the headphone case. In addition, the conductive parts in the headphone case need to be in a protruding state for a long time, and external impurities and water vapor are likely to contaminate the conductive parts in the headphone case, resulting in poor contact between the headphone and the headphone case. Summary of the Utility Model

[0004] The embodiments of this application provide an electronic device, which can solve the problem in the prior art that the connection pins of the headphone and the charging mechanism of the charging base are in contact for a long time, the connection pins are easily worn, or the charging mechanism is easily contaminated by external impurities and water vapor, resulting in poor contact of the device.

[0005] The embodiments of this application provide a headphone assembly, including: a charging base, including a body and a charging mechanism. The body includes a receiving cavity and a receiving groove provided on its surface. The groove wall of the receiving groove is provided with an opening communicating with the receiving cavity. The charging mechanism is arranged in the receiving cavity, and at least part of the charging mechanism is reciprocatingly telescopic; a headphone, arranged in the receiving groove, and the headphone includes connection pins. Among them, when the charging base is in the charging state, at least part of the charging mechanism extends and passes through the opening, and the charging mechanism is electrically connected to the connection pins; when the charging base is in the power-off state, at least part of the charging mechanism contracts, and the charging mechanism and the connection pins are spaced apart.

[0006] Thus, in the earphone assembly provided by the embodiments of the present application, the earphone assembly includes a charging base and an earphone. The charging base includes a body and a charging mechanism. The body includes a receiving cavity and a receiving groove provided on its surface. The earphone is disposed in the receiving groove, and the receiving groove serves to receive and fix the earphone. The charging mechanism is disposed in the receiving cavity. An opening communicating with the receiving cavity is provided on the groove wall of the receiving groove. At least part of the charging mechanism is reciprocatingly telescopic. In this way, when the charging base is in a charging state, at least part of the charging mechanism can extend and be electrically connected to the connection pins of the earphone located in the receiving groove through the opening, and the charging base charges the earphone. When the charging base is in a power-off state, the charging mechanism contracts, and the charging mechanism and the connection pins are spaced apart to reduce the mutual contact time between the two, improve the wear problem of the connection pins, and when in the contracted state, it also improves the problem that the charging mechanism is easily contaminated by impurities and water vapor in the external environment.

[0007] Therefore, in the embodiments of the present application, by providing a reciprocatingly telescopic charging mechanism, when in the charging state, the charging mechanism can extend and contact the connection pins of the earphone to ensure that when the earphone needs to be charged, the charging base can smoothly supply power to the earphone; while in the power-off state, the charging mechanism contracts, the charging mechanism and the connection pins are spaced apart, and the charging mechanism and the connection pins do not contact each other. By reducing the mutual contact time between the two, the problem of poor contact between the earphone and the charging base caused by the wear problem of the connection pins is improved; when in the power-off state, the charging mechanism contracts, and the volume of the charging mechanism exposed outside the receiving cavity decreases, so as to improve the problem that the charging mechanism is contaminated by impurities and water vapor in the external environment, resulting in poor contact between the earphone and the charging base.

[0028] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural view of the charging base 110 of the earphone assembly 100 in a power-off state according to some embodiments of this application; Figure 2 which is a schematic structural view of the charging base 110 of the earphone assembly 100 in a charging state according to some embodiments of this application.

[0029] As Figure 1 and Figure 2As shown in the figure, an embodiment of the present application provides a headset assembly 100. The headset assembly 100 includes a charging base 110 and a headset 120. The charging base 110 includes a body 111 and a charging mechanism 112. The body 111 includes a receiving cavity 113 and a receiving groove 114 provided on its surface. An opening 117 communicating with the receiving cavity 113 is provided on the groove wall of the receiving groove 114. The charging mechanism 112 is disposed in the receiving cavity 113, and at least a part of the charging mechanism 112 is reciprocally telescopically disposed; the headset 120 is disposed in the receiving groove 114, and the headset 120 includes a connection pin 121. Among them, when the charging base 110 is in a charging state, at least a part of the charging mechanism 112 extends and passes through the opening 117, and the charging mechanism 112 is electrically connected to the connection pin 121; when the charging base 110 is in a power-off state, at least a part of the charging mechanism 112 contracts, and the charging mechanism 112 and the connection pin 121 are spaced apart.

[0030] In the earphone assembly 100 provided by the embodiment of the present application, the earphone assembly 100 includes a charging base 110 and an earphone 120. The charging base 110 includes a main body 111 and a charging mechanism 112. The main body 111 includes a receiving cavity 113 and a receiving groove 114 provided on its surface. The earphone 120 is disposed in the receiving groove 114. The receiving groove 114 serves to receive and fix the earphone 120. The charging mechanism 112 is disposed in the receiving cavity 113. An opening 117 communicating with the receiving cavity 113 is provided on the wall of the receiving groove 114. At least a part of the charging mechanism 112 is reciprocally telescopically disposed. In this way, when the charging base 110 is in a charging state, at least a part of the charging mechanism 112 can extend and pass through the opening 117 to be electrically connected to the connection pin 121 of the earphone 120 located in the receiving groove 114, and the charging base 110 charges the earphone 120. When the charging base 110 is in a power-off state, the charging mechanism 112 contracts, and the charging mechanism 112 and the connection pin 121 are spaced apart to reduce the mutual contact time between the two, improve the wear problem of the connection pin 121, and also improve the problem that the charging mechanism 112 is easily contaminated by impurities and water vapor in the external environment when in the contracted state. By providing the reciprocally telescopically disposed charging mechanism 112, when in the charging state, the charging mechanism 112 can extend and contact the connection pin 121 of the earphone 120 to ensure that when the earphone 120 needs to be charged, the charging base 110 can smoothly supply power to the earphone 120; while in the power-off state, the charging mechanism 112 contracts, the charging mechanism 112 and the connection pin 121 are spaced apart, and the charging mechanism 112 and the connection pin 121 do not contact each other. By reducing the mutual contact time between the two, the problem of poor contact between the earphone 120 and the charging base 110 caused by the wear problem of the connection pin 121 is improved; when in the power-off state, the charging mechanism 112 contracts, and the volume of the charging mechanism 112 exposed outside the receiving cavity 113 decreases, so as to improve the problem that the charging mechanism 112 is contaminated by impurities and water vapor in the external environment, resulting in poor contact between the earphone 120 and the charging base 110.

[0031] The main body 111 includes a receiving groove 114 opened on its surface. The earphone 120 is received in the receiving groove 114. The receiving groove 114 is used to fix the earphone 120 so that the earphone 120 and the charging base 110 maintain good stability. The shape of the receiving groove 114 matches the part of the earphone 120 that needs to be received in the receiving groove 114, and the specific shape can be designed by itself. Exemplarily, the earphone 120 is a rod-shaped earphone 120. When the rod part of the earphone 120 needs to be received in the receiving groove 114, the receiving groove 114 can be a deep cylindrical shape corresponding to the rod part of the earphone 120; or when a part of the head of the earphone 120 needs to be received in the receiving groove 114, the receiving groove 114 can be a shallow groove shape corresponding to the head of the earphone 120.

[0032] The main body 111 includes a receiving cavity 113 for receiving the charging mechanism 112. The receiving cavity 113 and the receiving groove 114 are arranged at intervals and are connected by an opening 117, so that the charging mechanism 112 located in the receiving cavity 113 can be electrically connected to the connection pin 121 of the earphone 120 located in the receiving groove 114 through the opening 117.

[0033] The position of the opening 117 in the receiving groove 114 matches the connection pin 121 of the earphone 120. The connection pin 121 of the earphone 120 is arranged facing the opening 117 to facilitate the connection between the charging mechanism 112 and the connection pin 121. The shape and size of the opening 117 can be designed by itself. Exemplarily, the opening 117 is a circular hole or a rectangular hole. Exemplarily, the receiving groove 114 includes a bottom wall 1142 and a side wall 1141 connected to each other, and the opening 117 can be arranged on either the bottom wall 1142 or the side wall 1141.

[0034] The charging mechanism 112 is arranged in the receiving cavity 113, and at least part of the charging mechanism 112 is telescopically arranged. Specifically, the charging mechanism 112 includes a circuit board 1121 and a connecting member 1122. The connecting member 1122 is arranged to be reciprocally telescopic. The connecting member 1122 is a conductive member, and the circuit board 1121 is used to control the electrical signal applied to the connecting member 1122. Optionally, a battery is further included in the charging mechanism 112, and the battery is connected to the connecting member 1122 through the circuit board 1121.

[0035] Optionally, the charging mechanism 112 further includes a driving motor. The driving motor is connected to the connecting member 1122 through a link group or a gear group. In the charging state, the driving motor drives the connecting member 1122 to extend and contact the connection pin 121. In the power-off state, the driving motor drives the connecting member 1122 and the connection pin 121 to be spaced apart from each other. The control accuracy of the driving motor is high to improve the connection reliability between the earphone 120 and the charging base 110; or the connecting member 1122 is an electrostrictive member or a magnetostrictive member, and the connecting member 1122 is controlled to expand and contract by applying an electrical signal or a magnetic field to the connecting member 1122, so as to reduce the number of parts and the manufacturing difficulty.

[0036] The earphone 120 includes a connection pin 121. The connection pin 121 is a conductive member. Exemplarily, the connection pin 121 is a metal sheet or a metal spring piece, etc. In the related art, a coating is provided on the surface of the connection pin 121 to improve the electrical conductivity, wear resistance, corrosion resistance, heat dissipation performance, etc. of the connection pin 121. In the related art, when the earphone 120 is arranged in the receiving groove 114, the connection pin 121 and the charging mechanism 112 are always in contact, which easily causes the surface coating of the connection pin 121 to wear, and then causes poor contact between the connection pin 121 and the charging mechanism 112. And it can also reduce the wear resistance requirement for the surface coating of the connection pin 121, and reduce the processing difficulty and production cost of the connection pin 121.

[0037] In the embodiment of the present application, only when the charging base 110 is in a charging state, the charging mechanism 112 will extend and contact the connection pin 121, and the charging base 110 supplies power to the earphone 120; when the charging base 110 is in a power-off state, the charging mechanism 112 contracts, the charging mechanism 112 does not contact the connection pin 121, and the connection pin 121 will not be worn by the charging mechanism 112. This is equivalent to reducing the contact time between the connection pin 121 and the charging mechanism 112, so as to improve the problem that the connection pin 121 is worn by the charging mechanism 112, and the service life of the earphone assembly 100 can be extended.

[0038] Specifically, the earphone assembly 100 is wirelessly connected to the control terminal. The control terminal can be a mobile phone, a Personal Digital Assistant (PDA), a tablet computer, a laptop computer, etc. The power of the earphone 120 can be displayed on the control terminal. When the power of the earphone 120 reaches the first preset value, the earphone 120 is placed into the receiving groove 114, and the charging base 110 is controlled to enter the charging state through the control terminal, and the charging base 110 charges the earphone 120; when the power of the earphone 120 reaches the second preset value, the charging base 110 is controlled to enter the power-off state through the control terminal, or the charging base 110 automatically enters the power-off state when the earphone 120 is fully charged. Or a button is provided on the charging base 110. The button can be a physical button and a virtual button. The charging base 110 is controlled to enter the charging state through the button, and the charging base 110 can also be controlled to enter the power-off state through the button, or the charging base 110 automatically enters the power-off state after the earphone 120 is fully charged.

[0039] Optionally, when the charging base 110 is in a power-off state, the charging mechanism 112 contracts into the receiving cavity 113 to reduce the contact area between the charging mechanism 112 and the external environment, and improve the problem that the water vapor or impurities in the external environment contaminate the charging mechanism, resulting in poor contact between the earphone 120 and the charging base 110. The external environment here can refer to the environment outside the receiving cavity 113.

[0040] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of the earphone assembly 100 according to some embodiments of the present application.

[0041] In some embodiments, such as Figure 2 and Figure 3As shown, the charging base 110 also includes a shielding mechanism 115, which is connected to the main body 111. In the power-off state, the charging mechanism 112 is located in the accommodating cavity 113, and the shielding mechanism 115 covers the entire opening 117; in the charging state, the shielding mechanism 115 covers part of the opening 117, or the shielding mechanism 115 and the opening 117 are spaced apart so that the charging mechanism 112 can pass through the opening 117.

[0042] In these embodiments, the charging base 110 also includes a shielding mechanism 115 connected to the main body 111. In the power-off state, the charging mechanism 112 is located in the accommodating cavity 113, and the shielding mechanism 115 covers the entire opening 117. The shielding mechanism 115 isolates the external environment from the charging mechanism 112 to reduce the risk of water vapor and impurities in the external environment contaminating the charging mechanism 112.

[0043] In the power-off state, the charging mechanism 112 retracts into the accommodating chamber 113, and the shielding mechanism 115 covers the opening 117 to isolate the charging mechanism 112 from the external environment, thereby reducing the risk of foreign matter or external impurities adhering to the charging mechanism 112 and causing corrosion of the charging mechanism 112. The external environment refers to the environment outside the accommodating chamber 113.

[0044] In the charging state, the shielding mechanism 115 avoids the charging mechanism 112, a part of the opening 117 is shielded by the shielding mechanism 115, and the other areas of the opening 117 can allow the charging mechanism 112 to pass through; or the shielding mechanism 115 and the opening 117 are arranged at intervals, and the charging mechanism 112 can pass through the opening 117.

[0045] Exemplarily, the shielding mechanism 115 includes a driving motor and a shielding plate, and the driving motor controls the shielding plate to flip or translate relative to the opening 117; or the shielding mechanism 115 is an electrodeformable material or a magnetodeformable material, and moves relative to the opening 117 under the action of an electric current or a magnetic field; or the shielding mechanism 115 is movably connected to the main body 111, and moves relative to the opening 117 through the action of the charging mechanism 112.

[0046] See also Figure 4 and Figure 5 , Figure 4 This is a schematic structural diagram of the charging base 110 of the earphone assembly 100 in some embodiments of the present application in a charging state; Figure 5 This is a schematic structural diagram of the charging base 110 of the earphone assembly 100 in some embodiments of the present application in a power-off state.

[0047] In some embodiments, Figures 2 to 5As shown, the shielding mechanism 115 includes a first shielding portion 1151. One end of the first shielding portion 1151 is rotatably connected to the main body 111. In the charging state, the charging mechanism 112 extends and presses against the first shielding portion 1151, and the first shielding portion 1151 flips away from the accommodation cavity 113; in the power-off state, the charging mechanism 112 contracts into the accommodation cavity 113, and the first shielding portion 1151 flips towards the accommodation cavity 113 and covers the opening 117.

[0048] In these embodiments, the first shielding portion 1151 is rotatably connected to the main body 111. In the charging state, the first shielding portion 1151 flips open due to the pressing of the charging mechanism 112, without the need to provide additional driving components, which helps to reduce the number of parts and the processing difficulty.

[0049] Specifically, one end of the first shielding portion 1151 is pivotally or hingedly connected to the groove wall of the accommodation groove 114. In the power-off state, the first shielding portion 1151 covers the opening 117; when the state changes from the power-off state to the charging state, the charging mechanism 112 extends and presses against the first shielding portion 1151 through the opening 117. The first shielding portion 1151 flips towards the inside of the accommodation groove 114 under the action of the charging mechanism 112. During the flipping process, the first shielding portion 1151 will simultaneously press and lift the earphone 120, and the earphone 120 moves along the extending direction of the charging mechanism 112. When the charging mechanism 112 extends a certain length, the first shielding portion 1151 disengages from the end of the charging mechanism 112. At this time, the charging mechanism 112 contacts and maintains electrical connection with the connection pin 121.

[0050] Optionally, the opening 117 is provided on the bottom wall 1142 of the accommodation groove 114. When the state changes from the power-off state to the charging state, the shielding mechanism 115 lifts the earphone 120 and moves it in a direction away from the bottom wall 1142 of the accommodation groove 114.

[0051] Optionally, the charging base 110 further includes a cover body. The cover body covers the opening 117 of the accommodation groove 114. An elastic member is provided on the surface of the cover body facing the accommodation groove 114. In the power-off state, the earphone 120 contacts the elastic member to keep the earphone 120 stable in the accommodation groove 114; in the charging state, the earphone 120 moves towards the elastic member, and the elastic member undergoes elastic deformation to accommodate the earphone 120, so that the earphone 120 remains stable in the accommodation groove 114.

[0052] Optionally, two first shielding portions 1151 are disposed on both sides of the opening 117. In the power-off state, the two first shielding portions 1151 are in contact with each other, and the two first shielding portions 1151 cooperate to cover the opening 117. Relatively speaking, when the two first shielding portions 1151 cooperate to cover the opening 117, their extension dimension is shorter. In this way, the charging mechanism 112 can extend a shorter dimension to contact the connection pin 121. Similarly, when the earphone 120 is lifted by a smaller distance, it can be electrically connected to the charging mechanism 112.

[0053] Please refer to Figure 6 , Figure 6 which is a partial structural schematic diagram of the earphone assembly 100 according to some embodiments of the present application.

[0054] In some embodiments, as Figure 2 , Figure 5 and Figure 6 shown, the first shielding portion 1151 includes a substrate 1153, a rotating shaft 1154, and a return torsion spring 1155. The substrate 1153 is rotatably connected to the body 111 through the rotating shaft 1154. In the power-off state, the substrate 1153 covers the opening 117. The return torsion spring 1155 is sleeved on the rotating shaft 1154, and both ends of the return torsion spring 1155 are respectively connected to the substrate 1153 and the body 111.

[0055] In these embodiments, by providing the return torsion spring 1155 on the first shielding portion 1151, the elastic force of the return torsion spring 1155 can be used to increase the pressing force of the substrate 1153 at the opening 117 in the power-off state, and to improve the problem that the first shielding portion 1151 flips by itself under the action of an external force; so that when the charging state is converted to the power-off state, the return torsion spring 1155 can help the substrate 1153 to reset, and to improve the problem that the substrate 1153 cannot be reset due to interference between the substrate 1153 and the earphone 120.

[0056] The return torsion spring 1155 includes a compressed state and an extended state. When the return torsion spring 1155 is in the extended state, the substrate 1153 covers the opening 117; when the charging mechanism 112 extends and squeezes the substrate 1153 to flip, the return torsion spring 1155 is in the compressed state, and when the charging mechanism 112 retracts, the return torsion spring 1155 drives the substrate 1153 to flip towards the opening 117.

[0057] Optionally, a plurality of return torsion springs 1155 are sleeved on the rotating shaft 1154 to increase the reset force of the first shielding portion 1151.

[0058] Please refer to Figure 7 , Figure 7 which is a structural schematic diagram of the earphone assembly 100 according to some embodiments of the present application.

[0059] In some embodiments, as Figure 2 andFigure 7 As shown, the receiving groove 114 includes a bottom wall 1142 and a side wall 1141. The opening 117 is provided on the bottom wall 1142. The charging base 110 further includes a support member 116. The support member 116 is provided on the bottom wall 1142 to support the earphone 120, so that a gap is formed between the earphone 120 and the bottom wall 1142. In the charging state, the first shielding portion 1151 is flipped into the gap.

[0060] In these embodiments, a gap is formed between the earphone 120 and the bottom wall 1142 by the support member 116, so as to avoid interference with the earphone 120 during the flipping process of the first shielding portion 1151, which not only improves the connection reliability between the earphone 120 and the charging base 110, but also improves the problem of extrusion damage between the first shielding portion 1151 and the earphone 120.

[0061] The support member 116 and the first shielding portion 1151 are spaced apart to avoid mutual interference between the support member 116 and the first shielding portion 1151. The support member 116 is bonded or snapped onto the bottom wall 1142 of the receiving groove 114 to improve the connection reliability between the support member 116 and the receiving groove 114. The size of the support member 116 matches the size of the first shielding portion 1151, and the size and properties of the support member 116 can be set by itself. Exemplarily, the size of the support member 116 is the same as the extension size of the first shielding portion 1151, so as not to interfere with the earphone 120 during the flipping process of the first shielding portion 1151.

[0062] Optionally, the support member 116 can be a rubber block, or a foam block, or a silica gel block, etc., to improve the problem that the earphone 120 is bruised by the support member 116.

In the charging state, the electromagnetic coil 1123 is energized to generate a magnetic field, and the connecting member 1122 extends and connects to the connection pin 121; in the power-off state, the electromagnetic coil 1123 is de-energized.

[0079] In these embodiments, the charging mechanism 112 includes a circuit board 1121, a connecting member 1122, and an electromagnetic coil 1123.

Under the magnetic field of the electromagnetic coil 1123, the connecting member 1122 can reciprocally expand and contract without the need for additional driving parts, which helps reduce the processing difficulty of the charging base 110.

[0080] Magnetostriction refers to the elongation or shortening of an object in the magnetization direction when it is magnetized in a magnetic field. A magnetostrictive material is a material whose size changes significantly when the current passing through the electromagnetic coil 1123 changes or the distance from a magnet changes. The magnetostrictive material can be a metallic magnetostrictive material or a ferrite magnetostrictive material.

[0084] In these embodiments, the charging mechanism 112 includes at least two connecting members 1122 arranged at intervals, and the distances between each connecting member 1122 and the electromagnetic coil 1123 are the same, so that the electromagnetic coil 1123 can simultaneously control the expansion and contraction degrees of two or more connecting members 1122.

[0085] The distances between each connecting member 1122 and the electromagnetic coil 1123 are the same, so that the magnetic field intensities at each connecting member 1122 are the same. In this way, under the control of the same electromagnetic coil 1123, the expansion and contraction conditions of each connecting member 1122 are also the same.

[0086] Optionally, a plurality of connecting members 1122 are arranged around the electromagnetic coil 1123, and the distances between each connecting member 1122 and the electromagnetic coil 1123 are the same.
