Technical Field
[0001] This utility model relates to the field of Bluetooth headset charging terminal technology, and in particular to a charging structure for a Bluetooth headset's sound output network. Background Technology
[0002] Currently, conventional wireless Bluetooth earbuds charge their earbuds via a connection between the earbuds' dedicated charging terminals and the charging case's contact springs. However, this design generally suffers from the following technical flaws: First, placing the charging terminal inside the earphone takes up some space, making it difficult for researchers to develop smaller earphones or to fit larger batteries to enhance the earphone's battery life.
[0003] Second, once the charging terminal is installed inside the earphone, a special sealing design is required, such as applying glue or adding a sealing ring. This makes it difficult to achieve waterproof design for the earphone and results in poor reliability.
[0004] Third, the two charging terminals of the headphones are essential, making it difficult for manufacturers to reduce the material and assembly costs of headphone production. Utility Model Content
[0005] To overcome the shortcomings in the aforementioned background technology, the technical problem is to provide a charging structure for Bluetooth headsets with an output mesh that can replace the charging terminal, making the waterproof design of the headset easier to implement and more reliable, and facilitating better space saving and reducing the production cost of the headset.
[0006] The technical solution of this utility model is: a charging structure for a Bluetooth headset's sound outlet, characterized in that it includes: Earphone shell; A charging device, disposed within the earphone housing, comprises: A conductive plate is disposed on the earphone housing; A pair of probes electrically connected to an external power source and in active contact with the conductive plate to form a charging circuit between the conductive plate and the probes.
[0007] Furthermore, it also includes a charging stand, which has several receiving cavities adapted to the earphone shell. The receiving cavities are used to place the earphone shell. Each receiving cavity is provided with a pair of probes. A power supply board is disposed on the charging stand and is electrically connected to the several pairs of probes. When the earphone shell is placed in the receiving cavity of the charging support, the probe contacts the conductive plate to form an electrical connection.
[0008] Furthermore, it also includes a power receiving board disposed on the conductive board, the power receiving board being connected to a wire, and the other end of the wire being connected to a connecting plate.
[0009] Furthermore, the conductor is a flexible circuit board.
[0010] Furthermore, the earphone housing includes a connecting sleeve, with an upper housing and a lower housing on each side of the connecting sleeve. The connecting sleeve is connected to the upper housing and the lower housing by snap-fit, and the three together form a spherical cavity. The spherical cavity is composed of a rear cavity space of the speaker and a front cavity space of the speaker.
[0011] Furthermore, the conductive plate is attached to the lower housing by a snap-fit mechanism, and the conductive plate includes two sound-emitting meshes, which are respectively connected to the positive and negative terminals of the power receiving plate.
[0012] Furthermore, each of the sound-emitting meshes has a protrusion, and the two protrusions are respectively connected to the positive and negative terminals of the power receiving plate.
[0013] Furthermore, the conductive plate is snapped onto the connecting sleeve, and the conductive plate includes two rear cavity meshes, which are respectively connected to the positive and negative poles of the receiving plate.
[0014] Furthermore, each of the rear cavity meshes is formed with a protrusion, and the two protrusions are respectively connected to the positive and negative terminals of the power receiving plate.
[0015] Furthermore, it also includes the PCB motherboard, battery, and speaker body; The PCB motherboard is disposed in the rear cavity space of the speaker inside the upper housing and is connected to the connecting plate; The battery is disposed inside the connecting sleeve, with a portion located in the rear cavity space of the speaker and another portion located in the front cavity space of the speaker. The speaker body is disposed in the front cavity space of the speaker within the lower housing, and both the speaker body and the battery are connected to the PCB motherboard.
[0016] The beneficial effects of this utility model are: By using the sound outlet mesh as the headphone charging terminal, the headphone charging terminal is eliminated without affecting the sound outlet mesh's sound output function. This makes the product's waterproof design easier to achieve and more reliable. At the same time, it saves internal stacking space in the headphones, making it easier to develop smaller headphones or to fit larger batteries to extend the headphone's battery life. Furthermore, replacing the headphone charging terminal with the sound outlet mesh effectively reduces the material and assembly costs of headphone production. Attached Figure Description

Detailed Implementation
[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0026] like Figures 1 to 7 The diagram shows a charging structure for a Bluetooth headset, comprising a charging base 101. The charging base 101 has at least one receiving cavity adapted to the headset shell. A pair of probes 103 are slidably connected within each receiving cavity. At least one headset shell is disposed within the corresponding receiving cavity. A charging device is provided within the headset shell, including: A conductive plate is disposed on the earphone housing; A pair of probes 103 are electrically connected to an external power source and make active contact with a conductive plate to form a charging circuit between the conductive plate and the probes 103.
[0027] A Bluetooth headset charging structure with a sound outlet also includes a charging support 101, which has several receiving cavities adapted to the headset shell. The receiving cavities are used to place the headset shell. Each receiving cavity is provided with a pair of probes 103. A power supply board 102 is disposed on the charging support 101 and is electrically connected to the several pairs of probes 103. When the earphone shell is placed in the receiving cavity of the charging support 101, the probe 103 contacts the conductive plate to form an electrical connection.
[0028] A charging structure for a Bluetooth headset also includes a power receiving board 42 disposed on a conductive board. The power receiving board 42 is connected to a wire, and the other end of the wire is connected to a connecting board 43. The wire is a flexible circuit board. Of course, in other preferred embodiments, the wire can be other flexible conductive structures that can realize electrical connection functions.
[0029] In this embodiment, the charging stand 101 may have one or more receiving cavities, and each receiving cavity is provided with a pair of probes 103, so that the charging stand 101 can charge one or more earphones.
[0030] The earphone housing includes a connecting sleeve 22. An upper housing 21 and a lower housing 23 are respectively provided on both sides of the connecting sleeve 22. A cavity is formed inside the upper housing 21, the connecting sleeve 22 and the lower housing 23. The cavity is a spherical cavity, which is composed of a rear cavity space 31 of the speaker and a front cavity space 32 of the speaker.
[0031] A Bluetooth headset charging structure with a sound outlet also includes a PCB motherboard 51, which is disposed in the rear cavity space 31 of the speaker within the upper housing 21. The PCB motherboard 51 is connected to a connecting board 43. A battery 52 is disposed in a connecting sleeve 22, with one part of the battery 52 located in the rear cavity space 31 of the speaker and the other part located in the front cavity space 32 of the speaker. A speaker body 53 is disposed in the front cavity space 32 of the speaker within the lower housing 23. Both the speaker body 53 and the battery 52 are connected to the PCB motherboard 51.
[0032] In this embodiment, by forming a spherical cavity in the earphone shell, there is enough space inside the earphone shell to assemble the PCB motherboard 51, battery 52 and speaker body 53, and the layout of the three is reasonable, making the waterproof design of the product easier to achieve and more reliable.
[0033] A conductive plate is disposed on the lower housing 23. The conductive plate includes two sound-emitting meshes 44. The two sound-emitting meshes 44 are respectively disposed on the lower housing 23 by snap-fit. Each sound-emitting mesh 44 has a protrusion 45. The protrusions 45 of the two sound-emitting meshes 44 are respectively connected to the positive and negative poles of the receiving plate 42.
[0034] In this embodiment, two sound-emitting nets 44 can be provided, and the protrusions 45 of each sound-emitting net 44 are respectively connected to the positive and negative poles of the power receiving board 42; of course, in other embodiments, one sound-emitting net 44 can also be provided, with two protrusions 45 on the sound-emitting net 44, and the two protrusions 45 are insulated from each other, and the two protrusions 45 on one sound-emitting net 44 are respectively connected to the positive and negative poles of the power receiving board 42.
[0035] Specific working principle: The power supply board 102 is used to supply power to the probes 103. When the headphones need to be charged, the headphones are placed in the charging stand 101. The two probes 103 corresponding to the upper and lower shells 23 of the headphones are then inserted into the metal sound outlet mesh 44. One probe 103 is connected to the positive terminal of the power receiving board 42, and the other probe 103 is connected to the negative terminal of the power receiving board 42. Then, the power supply board 102 transmits current to the power receiving board 42 through the probes 103. Then, the current on the power receiving board 42 passes through the flexible circuit board 41, the connecting board 43, and the PCB main board 51 in sequence before finally being delivered to the battery 52. When the headphones are finished charging or when the headphones need to be used, the headphones can be directly removed from the charging stand 101. The probes 103 then separate from the sound outlet mesh 44, and the headphones stop charging.
[0036] By utilizing the inherent design structure of headphones—the sound output mesh 44—as the headphone charging terminal, a new function of the sound output mesh 44 is brought into play without affecting its sound output function. Compared with traditional wireless headphones, the headphone charging terminal is eliminated, making the waterproof design of the product easier to achieve and more reliable. At the same time, it saves the internal stacking space of the headphones, making it easier to develop smaller headphones or to put in a larger battery 52 to extend the headphone's battery life.
[0037] Secondly, traditional headphones require two charging terminals and one sound outlet mesh 44. After the improvement, the headphones only need two sound outlet meshes 44, and the sum of the areas of the two sound outlet meshes 44 is roughly the same as the area of the previous single sound outlet mesh 44, thereby effectively reducing the material and assembly costs of headphone production.
[0038] like Figure 3 and Figure 5 As shown, in a preferred embodiment, a conductive plate is disposed on a connecting sleeve 22. The conductive plate includes two rear cavity meshes 6, which are respectively disposed on the connecting sleeve 22 by snap-fit. Each rear cavity mesh 6 has a protrusion, and the protrusions of the two rear cavity meshes 6 are respectively connected to the positive and negative poles of the receiving plate 42.
[0039] In this embodiment, two rear cavity meshes 6 can be provided, and the protrusions of each rear cavity mesh 6 are respectively connected to the positive and negative poles of the power receiving plate 42; of course, in other embodiments, one rear cavity mesh 6 can also be provided, with two protrusions on the rear cavity mesh 6, and the two protrusions are insulated from each other, and the two protrusions on one rear cavity mesh 6 are respectively connected to the positive and negative poles of the power receiving plate 42.
[0040] Specific working principle: During use, the positive and negative terminals of the receiving plate 42 are connected to the protrusions of the two rear cavity meshes 6, respectively. The rear cavity meshes 6 are also made of conductive metal. When the headphones need to be charged, the headphones are placed in the charging support 101, so that the two probes 103 of the same pair are inserted into the two rear cavity meshes 6, thereby charging the battery 52. By flexibly setting the conductive plate in different areas, such as the sound outlet of the headphones or the rear cavity, while ensuring acoustic performance, it can better adapt to the appearance and ergonomic requirements of the headphones, and facilitate the alignment convenience and connection stability when charging the headphones.
[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
