Description

Technical Field

[0001] This utility model relates to the field of Bluetooth receiver technology, specifically to a miniature Bluetooth receiver with an audio head that supports 180-degree adjustment. Background Technology

[0002] Currently, in order to convert the Bluetooth signal from the Bluetooth receiver into an audio signal and transmit it to audio equipment, headphones, car audio systems, or other audio playback devices, Bluetooth receivers are usually equipped with an audio connector. To connect to the audio connector, the Bluetooth receiver typically has an audio jack (socket, receiver port) on its casing that connects to the receiver's mainboard. When the audio connector is plugged into this audio jack, it ensures that the mainboard in the Bluetooth receiver can transmit the signal to the audio connector, thus guaranteeing normal audio signal transmission.

[0003] Because most existing Bluetooth receivers have their audio jacks directly fixed to the receiver's housing, the audio connector connected to the audio jack is also fixed to the housing. This makes it difficult for Bluetooth receivers with audio connectors to be used in some confined spaces (such as embedded speakers). Utility Model Content

[0004] This invention proposes a miniature Bluetooth receiver with an audio head that supports 180-degree adjustment, solving the problem in related technologies where the audio head is fixed, thus affecting the flexibility of Bluetooth receiver use.

The audio socket includes a connection part for plugging in an external audio head and a rotating part for rotatably connecting itself to the receiver housing.

[0007] Furthermore, the rotating part is provided with a clearance hole, which extends through the audio socket along the rotating part.

[0008] Furthermore, the two ends of the rotating part are located on both sides of the connecting part, and the projection surface of the audio socket on the vertical horizontal plane is a "T" shaped structure.

[0009] Furthermore, the receiver housing includes a top housing, a middle housing, and a bottom housing, which are detachably connected to each other. The audio jack is rotatably connected to the top housing. The top housing includes a housing body and a mating bracket, which are detachably connected. The rotating part is rotatably connected between the housing body and the mating bracket, and a gap is left between the mating bracket and the inner surface of the housing body.

[0010] Furthermore, the housing body is provided with a first arched hole, the mating bracket is provided with a second arched hole for mating with the first arched hole, and the rotating part is located between the first arched hole and the second arched hole.

[0011] Furthermore, a plurality of fasteners are provided between the mating bracket and the housing body for fixing the mating bracket to the housing body, and each of the fasteners is threadedly connected to the housing body.

[0012] Furthermore, a first snap-fit ​​structure is provided between the top shell and the middle shell, and a second snap-fit ​​structure is provided between the middle shell and the bottom shell.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] In this invention, the audio jack is rotatably connected to the receiver housing, allowing the external audio head connected to the audio jack to adjust its angle relative to the receiver housing via this rotatable connection.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0026] like Figure 1 As shown, this embodiment proposes a miniature Bluetooth receiver with an audio head that supports 180-degree adjustment. It mainly includes a receiver housing 1, and the receiver housing 1 is provided with an audio socket 2. The audio socket 2 is rotatably connected to the receiver housing 1. That is, unlike traditional receivers, the audio socket 2 in this embodiment can rotate on the receiver housing 1, so that this embodiment can better adapt to some narrow usage environments and ensure the flexibility of use of this embodiment.

[0027] Specifically, such as Figure 4 As shown, the audio jack 2 includes a connecting part 21 for plugging in an external audio head and a rotating part 22 for rotatably connecting itself to the receiver housing 1. Preferably, the two ends of the rotating part 22 are located on both sides of the connecting part 21, that is, the connecting part 21 is centrally located on the rotating part 22, so that the projection surface of the audio jack 2 on the vertical horizontal plane is a "T" shaped structure. With the high strength and good bending resistance of the "T" shaped structure, and the fact that both ends of the audio jack 2 can be rotatably connected to the receiver housing 1, ensuring that the audio jack 2 has at least two support points on the receiver housing 1, the connection stability between the audio jack 2 and the receiver housing 1 is effectively guaranteed, and the audio jack 2 is prevented from detaching from the receiver housing 1 during rotation, thus effectively ensuring the stability of the overall structure of this embodiment.

[0028] like Figure 2As shown, the rotating part 22 in this embodiment is provided with a clearance hole 221. The clearance hole 221 passes through the audio socket 2 along the rotating part 22. Thus, the receiver motherboard in this embodiment can still be directly connected to the audio socket 2 by means of a connecting wire. The connecting wire enters the interior of the audio socket 2 along the clearance hole 221 and connects with the connecting part 21. That is, the existence of the clearance hole 221 can effectively prevent the rotation of the audio socket 2 from interfering with the connecting wire on the receiver motherboard located inside the receiver housing 1, thus ensuring the stability of the operation of this embodiment.

[0029] like Figures 2-3 , Figure 7 As shown, the receiver housing 1 in this embodiment includes a top housing 11, a middle housing 12, and a bottom housing 13. The top housing 11, the middle housing 12, and the bottom housing 13 are detachably connected to each other. The audio jack 2 is rotatably connected to the top housing 11. By replacing the corresponding parts in this embodiment, the audio jack 2 with different jack sizes can be replaced. This allows the installation of audio heads of different sizes (diameters) on this embodiment, enabling it to adapt to various audio devices and further improving the flexibility of use.

[0030] The top housing 11 includes a housing body 111 and a mating bracket 112. The housing body 111 and the mating bracket 112 are detachably connected. The rotating part 22 is rotatably connected between the housing body 111 and the mating bracket 112. That is, by completing the disassembly and assembly work between the housing body 111 and the mating bracket 112, the audio jack 2 can be removed from the housing body 111 and the mating bracket 112 or installed between the housing body 111 and the mating bracket 112, thereby realizing the separate replacement of the audio jack 2 without replacing the top housing 11 together, reducing the replacement cost when replacing the audio jack 2 in this embodiment.

[0031] Meanwhile, a first snap-fit ​​structure 4 is provided between the top shell 11 and the middle shell 12, and a second snap-fit ​​structure 5 is provided between the middle shell 12 and the bottom shell 13. The first snap-fit ​​structure 4 includes a first snap-fit ​​member and a first snap-fit ​​groove. The first snap-fit ​​member is made of elastic material and is fixedly connected to the top shell 11, while the first snap-fit ​​groove is opened on the middle shell 12. Through the mutual engagement of the first snap-fit ​​member and the first snap-fit ​​groove, the top shell 11 and the middle shell 12 are finally fixedly connected. The second snap-fit ​​structure includes a second snap-fit ​​member and a second snap-fit ​​groove. The second snap-fit ​​groove is made of elastic material and is fixedly connected to the bottom shell 13, while the second snap-fit ​​groove is opened on the middle shell 12. Through the mutual engagement of the second snap-fit ​​member and the second snap-fit ​​groove, the middle shell 12 and the bottom shell 13 are finally fixedly connected. That is, the receiver shell 1 in this embodiment is mainly composed of the top shell 11, the middle shell 12, and the bottom shell, which are snap-fitted together to achieve a detachable connection between the three, so as to realize the quick assembly and disassembly of the receiver shell 1 itself, thereby ensuring the replacement efficiency of the audio socket 2.

[0032] Preferably, in this embodiment, the first snap-fit ​​component is integrally formed with the top shell 11, and the second snap-fit ​​component is integrally formed with the bottom shell 13. The top shell 11 and the bottom shell 13 are preferably made of hard plastic materials with high hardness and good resilience, such as polyoxymethylene (POM). In this way, when it is necessary to disassemble the receiver shell 1, the first snap-fit ​​structure 4 and the second snap-fit ​​structure 5 are pressed along the outer contour of the top shell 11 and the bottom shell 13, so that the first snap-fit ​​component disengages from the first slot and the second snap-fit ​​component disengages from the second slot. Then, the top shell 11 and the bottom shell 13 are moved in the specified direction to complete the disassembly of the receiver shell 1.

[0033] like Figure 3 , Figures 5-6 As shown, a gap is left between the mating bracket 112 and the inner cavity surface of the housing body 111 so that the connecting wires on the receiver motherboard located in the receiver housing 1 can bypass the mating bracket 112 along the gap, thereby avoiding interference between the mating bracket 112 and the communication path between the receiver motherboard and the audio head, and ensuring the stability of signal transmission in this embodiment.

[0034] The housing body 111 is provided with a first arched hole 1111, and the mating bracket 112 is provided with a second arched hole 1121 for cooperating with the first arched hole 1111. The rotating part 22 is located between the first arched hole 1111 and the second arched hole 1121. That is, after the housing body 111 and the mating bracket 112 are mated, the first arched hole 1111 and the second arched hole 1121 fit together to form a rotating hole for the rotating part 22 to be inserted, so as to avoid the dispersion and detachable design of the top housing 11 from affecting the stability of the audio socket rotational connection on the top housing 11.

[0035] A plurality of fasteners 3 are provided between the fitting bracket 112 and the housing body 111 for fixing the fitting bracket 112 to the housing body 111. Each fastener 3 is threadedly connected to the housing body 111. Specifically, the fitting bracket 112 is provided with a countersunk hole, and the housing body 111 is provided with a threaded hole. The threaded hole and the countersunk hole are coaxially arranged. In this embodiment, the fastener 3 is preferably a bolt with a nut, so that after the fastener 3 is rotated a certain angle in the threaded hole, it can abut against the countersunk hole feature of the countersunk hole, thereby completing the assembly of the top housing 11. The fixing between the fitting bracket 112 and the housing body 111 is achieved by the thread, which can not only ensure the convenience of disassembling and assembling the top housing 11, but also effectively ensure the structural stability of the top housing 11 itself. Example

[0036] Unlike Embodiment 1, the receiver housing 1 in this embodiment is provided with a disassembly port for external slender objects such as hexagonal wrenches to penetrate the receiver housing 1 and contact the first and second snap-fit ​​components. This allows workers to better apply force to the first snap-fit ​​structure 4 and the second snap-fit ​​structure 5, thereby improving the efficiency of disassembling and dismantling the receiver housing 1. Example

[0037] Based on Embodiment 1 or Embodiment 2, this embodiment includes a Bluetooth connectivity module, allowing users to connect to devices such as mobile phones and tablets via Bluetooth. The specific Bluetooth connection method and operation via mobile phones or other devices depend on the Bluetooth module used, and will not be elaborated upon in this embodiment.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
