[0030] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0031] As described in the background art, in the prior art, the shell components of the audio signal transceiver are connected together by bolts, and the circuit board of the audio signal transceiver and the shell component are also connected by bolts. Therefore, when removing the circuit board during maintenance, multiple steps of bolt disassembly and assembly are required, which is inconvenient.

[0032] In order to solve this technical problem, the utility model provides an audio signal transceiver.

[0033] Specifically, please refer to Figure 1-Figure 3 , the audio signal transceiver specifically includes:

[0034] The housing structure 1 includes an upper cover 101, a protective shell 102 is provided above the upper cover 101, a lower cover 103 is provided below the upper cover 101, and a circuit board body 4 is connected to the lower cover 103 and the upper cover 101;

[0035] Several connecting parts are arranged between the protective shell 102, the upper cover 101, the circuit board body 4 and the lower cover 103. The connecting parts include a connecting hole 108 opened on the lower cover 103, a second limiting hole 401 opened on the circuit board body 4 and a first limiting hole 107 opened on the upper cover 101. A threaded column 106 is inserted between the second limiting hole 401 and the first limiting hole 107. One end of the threaded column 106 is fixedly connected to the protective shell 102, and the other end of the threaded column 106 is detachably connected to the connecting hole 108.

[0036] The audio signal transceiver provided by the present invention realizes the limitation of the circuit board body 4 by the provided threaded column 106 and the second limiting hole 401. During inspection or maintenance, it is only necessary to separate the lower cover 103 and the upper cover 101 to release the fixation of the circuit board body 4 and remove the circuit board body 4, which greatly simplifies the disassembly and assembly steps and improves work efficiency. Since the complexity of the disassembly and assembly process is reduced, the skill requirements of technicians are lowered, and the risk of damage caused by improper operation is reduced, which helps to reduce maintenance costs.

[0037] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0040] Example 1, please refer to Figure 1-Figure 3 An audio signal transceiver includes a housing structure 1, the housing structure 1 includes an upper cover 101, a protective shell 102 is provided above the upper cover 101, a lower cover 103 is provided below the upper cover 101, and a circuit board body 4 is connected to the lower cover 103 and the upper cover 101;

[0041] Several connecting parts are arranged between the protective shell 102, the upper cover 101, the circuit board body 4 and the lower cover 103, and the connecting parts include a connecting hole 108 opened on the lower cover 103, a second limiting hole 401 opened on the circuit board body 4 and a first limiting hole 107 opened on the upper cover 101, and a threaded column 106 is inserted between the second limiting hole 401 and the first limiting hole 107, one end of the threaded column 106 is fixedly connected to the protective shell 102, and the other end of the threaded column 106 is detachably connected to the connecting hole 108; the application realizes the limitation of the circuit board body 4 by setting the threaded column 106 and the second limiting hole 401. During inspection or maintenance, it is only necessary to separate the lower cover 103 and the upper cover 101 to release the fixation of the circuit board body 4 and remove the circuit board body 4, which greatly simplifies the disassembly and assembly steps and improves work efficiency; since the complexity of the disassembly and assembly process is reduced, the skill requirements of technical personnel are reduced, and the risk of damage caused by improper operation is reduced, which helps to reduce maintenance costs.

[0042] Furthermore, the threaded column 106 and the connecting hole 108 are connected by bolts. The housing structure 1 and the circuit board body 4 can be disassembled by unscrewing the bolts connecting the threaded column 106 and the connecting hole 108, which is easy to operate.

[0043] Further, such as Figure 4 As shown, a groove 114 is provided at the bottom of the lower cover 103 , and the groove 114 is communicated with the connecting hole 108 . The provision of the groove 114 facilitates the operation of the bolts from the outside.

[0044] Further, such as Figure 4 As shown, a support pad 115 is detachably connected to the groove 114. The support pad 115 can seal the groove 114 to prevent the bolts from being exposed. While improving the overall aesthetics, it can also ensure that when the shell structure 1 is placed on a supporting plane for use, there is a gap between the bottom of the lower cover 103 and the supporting plane to facilitate heat dissipation. The support pad 115 can be directly inserted into the groove 114 and limited by friction, or it can be bonded with glue.

[0045] Example 2 further optimizes the audio signal transceiver provided in Example 1. Specifically, Figure 2 and Figure 3As shown, a first limiting groove 110 is provided on the outer peripheral side of the top of the upper cover 101, and a first limiting ring 111 is provided on the bottom of the protective shell 102 to be plugged into the first limiting groove 110. The mutual cooperation between the first limiting ring 111 and the first limiting groove 110 can improve the stability of the connection between the upper cover 101 and the protective shell 102, and reduce the situation where the threaded column 106 is broken under stress.

[0046] Further, such as Figure 2 and Figure 3 As shown, a second limiting ring 113 is fixedly installed on the top of the lower cover 103, and a second limiting groove 112 is provided at the bottom of the upper cover 101 to be plugged into the second limiting ring 113, and the circuit board body 4 is also plugged into the inner wall of the second limiting groove 112. The mutual cooperation between the second limiting ring 113 and the second limiting groove 112 can improve the stability of the connection between the lower cover 103 and the upper cover 101. The plugging of the circuit board body 4 and the second limiting groove 112 completes the upper and lower direction limitation of the circuit board body 4, which makes the position of the circuit board body 4 inside the shell structure 1 more fixed, reduces the displacement caused by vibration or external force, and improves the overall stability and reliability.

[0047] Further, such as Figure 2 and Figure 3 As shown, several reinforcing plates 109 are fixedly connected to the outer surface of the threaded column 106 near one end of the protective shell 102. The reinforcing plates 109 are fixedly connected to the protective shell 102. The side walls of the first limiting holes 107 are provided with side grooves that are plugged into the reinforcing plates 109. The reinforcing plates 109 can reinforce the connection between the threaded column 106 and the protective shell 102, thereby improving the firmness of the threaded column 106.

[0048] When disassembling, first remove the support pad 115, unscrew the bolts connecting the threaded column 106 and the connecting hole 108, pull the lower cover 103 to separate the lower cover 103 from the upper cover 101, separate the second limiting hole 401 from the threaded column 106, and then take out the circuit board body 4. When installing, plug the second limiting hole 401 into the threaded column 106, put the lower cover 103 back in place, loosen the bolts between the connecting hole 108 and the threaded column 106, and install the support pad 115 into the groove 114.

[0049] Further, such as Figure 1 and Figure 6 As shown, a switching switch 2 is integrated on the shell structure 1, and a long opening 201 for the switching switch 2 to pass through is opened on the upper cover 101. The existing audio signal transceiver realizes two usage modes, namely, receiving mode and transmitting mode, through a Bluetooth receiving RX module and a Bluetooth transmitting TX module. When switching the mode, it is realized by switching the switch 2. This is the existing technology and will not be repeated in this application.

[0050] Furthermore, a limit member is provided in the elongated opening 201 , and the limit member is used to limit the switch 2 , thereby reducing the possibility of the switch 2 being accidentally touched during use, and ensuring the normal operation of the transceiver during use.

[0051] Further, such as Figure 5 and Figure 6 As shown, the limiting member includes a limiting block 3 inserted into the elongated opening 201, and a through hole 301 is opened on the limiting block 3. The inner wall of the through hole 301 is inserted into the switching switch 2. The limiting block 3 limits the switching switch 2, thereby reducing the possibility of the switching switch 2 being accidentally touched during use. When operating the switching switch 2, the limiting block 3 is directly pulled to separate the limiting block 3 from the elongated opening 201. After toggling the switching switch 2, the limiting block 3 is flipped over and then inserted into the elongated opening 201.

[0052] Example 3 further optimizes the audio signal transceiver provided in Example 1 or 2. Specifically, Figure 7 As shown, the circuit board body (4) is connected to a USB interface 6, a RUX interface 7, an RCA-L interface 8, an RCA-R interface 9, a COAXIAL interface 10, an OPTICAL interface 11 and a power supply interface 12;

[0053] This allows the application to connect two audios at the same time. The RUX interface 7 is connected to a speaker, and the RCA-L interface 8 and RCA-R interface 9 can also be connected to one to achieve dual output function. The setting of the USB interface 6 enables this application to support U disk playback;

[0054] RUX port 7 is an audio port, usually used to connect audio equipment;

[0055] RCA interface, also known as lotus socket, is a common audio and video interface. RCA interface is usually used for audio and video transmission, such as analog audio / video cable, digital audio cable and color difference component cable. RCA interface usually appears in pairs, that is, RCA-R interface 9 corresponds to the right channel, and RCA-L interface 8 corresponds to the left channel.

[0056] The COAXIAL interface 10, also known as the coaxial interface, is a common audio and video interface standard. Coaxial cable is used to transmit radio frequency signals and is commonly used for television signal transmission, satellite TV reception, and cable TV signal transmission. The coaxial interface uses coaxial cable as the transmission medium and has the advantages of constant impedance, wide transmission bandwidth, and low signal loss. In the audio field, the coaxial interface is often used for digital audio signal transmission.

[0057] The OPTICAL interface 11 generally refers to an interface that uses optical fiber as a transmission medium. It utilizes light transmission to achieve high-speed, long-distance data transmission. There are various types of optical fiber interfaces that can adapt to different network environments. In the audio field, the OPTICAL interface 11 is often used for the transmission of digital audio signals. Optical fiber transmission can achieve electrical isolation, preventing digital noise from being transmitted through the ground wire, which is beneficial to improving the signal-to-noise ratio of the DAC. That is, with digital coaxial (Coaxial) and digital optical (Optical) input functions, digital signal input can be realized, and it can also be converted into analog signal (AUX or RCA) output, that is, digital-to-analog conversion is achieved.

[0058] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0059] Obviously, the embodiments described above are only some of the embodiments of the present invention, rather than all of the embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms.
