Description

Technical Field

[0001] The present application relates to the technical field of external sound card structures, and in particular to a sound card. Background Art

[0002] A sound card, also called an audio card (or sound effect card in Hong Kong and Taiwan), is a fundamental component of a computer multimedia system. It's a piece of hardware that converts sound waves into digital signals. Its basic function is to convert raw sound signals from microphones, tapes, and CDs, outputting them to audio devices like headphones, speakers, amplifiers, and recorders, or to synthesize the sounds of musical instruments via the MIDI interface.

[0003] An external sound card is an audio interface device that connects to a computer or mobile device via USB. It's convenient and portable, making it particularly suitable for environments requiring superior sound quality, such as laptops. External sound cards offer a wider range of interfaces and higher-quality sound, supporting multiple platforms like Windows, Mac, and iOS, and providing a variety of interfaces to meet diverse recording needs.

[0004] However, existing external sound cards have a simple shape and only provide basic functions, so that users can only enjoy the auditory sense when using them, but cannot have a strong visual effect. Summary of the Invention

[0005] The present invention provides a sound card for connecting to an external device to realize mutual conversion between sound waves and digital signals, including:

[0006] The housing has a receiving cavity;

[0007] A control assembly, including a first circuit board, is disposed in the accommodating cavity;

[0008] a light-emitting component, disposed in the accommodating cavity and electrically connected to the first circuit board, for emitting light;

[0009] The light guide structure is provided in the housing and is used for conducting the light emitted by the light emitting component to the outside of the housing.

[0010] Compared with the sound cards in the prior art, which have the technical problem of a single shape and an inability to produce a strong visual effect, the sound card provided in the present application adopts a light-guiding structure to transmit the light emitted by the light-emitting component to the outside of the shell, so that the user can observe the colorful light, create a better lighting atmosphere, and produce a strong visual effect; thus, the user can enjoy the auditory effect while combining the visual effect, thereby creating a more three-dimensional atmosphere and improving the user experience.

[0011] In one embodiment, the light guide structure includes a first light guide member, which is disposed on the housing and located on at least two side surfaces of the housing. Positioning the first light guide member on the side surfaces of the housing provides a glare effect without affecting the operation of the sound card, thereby enhancing the user's visual experience.

[0012] In one embodiment, the first light guide comprises a main body and a first engaging portion connected to the main body. The main body is disposed in a mounting hole on the housing and is at least partially exposed outside the housing. A second engaging portion is disposed on a side of the housing facing the accommodating cavity, and the first engaging portion engages with the second engaging portion. The main body is disposed on the housing to enhance the overall appearance of the product and to provide a more secure mounting of the first light guide through the engaging portion.

[0013] In one embodiment, the first light guide further includes a limiting portion provided on a side of the main body away from the first clamping portion, and an abutting portion connected to the main body, wherein the limiting portion abuts the shell and is provided in the accommodating cavity, and the abutting portion abuts the shell; a deformation portion is further provided between the abutting portion and the first clamping portion. The limiting portion is adjacent to or abuts the side plate, and extends from the main body toward the bottom plate, thereby confining the first light guide within the accommodating cavity and preventing it from being removed from the mounting hole, thereby ensuring the installation stability of the first light guide; the deformation portion is provided so that there is deformation space during the clamping installation, thereby improving assembly efficiency and reducing wear between the two.

[0014] In one embodiment, the light-guiding structure further includes a first light-shielding member, which is disposed in the accommodating cavity and connected to the housing. A light-guiding cavity is further disposed within the housing, and the sidewalls of the light-guiding cavity include the first light-guiding member and the first light-shielding member. Light emitted by the light-emitting component is sequentially transmitted through the light-guiding cavity and the first light-guiding member to the exterior of the housing. The provision of the first light-shielding member ensures that light emitted by the light-emitting component can only be transmitted through the light-guiding cavity and the first light-guiding member to the exterior of the housing, thereby preventing any impact on other components of the sound card and light leakage, thereby enhancing the lighting atmosphere.

[0015] In one embodiment, the light-emitting assembly includes a first light-emitting unit electrically connected to the first circuit board. The first light-emitting unit is disposed in the light-guiding cavity, and light emitted by the first light-emitting unit is transmitted to the outside of the housing via the first light-guiding member. Placing the first light-emitting unit in the light-guiding cavity allows light emitted by the first light-emitting unit to be directly transmitted out of the housing via the first light-guiding member, thereby reducing energy loss.

[0016] In one embodiment, the control assembly further includes a function key disposed within the housing and exposed outside the housing, and electrically connected to the first circuit board, for adjusting the amplification level of the signal input to the sound card and / or the signal strength of the signal output by the sound card, and / or enabling or disabling a mute function of the sound card. Providing the function key allows for better control or adjustment of the sound card, improving its efficiency.

[0017] In one embodiment, the function keys are light-transmissive; the light-emitting assembly further includes a second light-emitting unit electrically connected to the first circuit board, the second light-emitting unit being disposed in the accommodating cavity and emitting light that is transmitted through the function keys to the exterior of the housing. The provision of the second light-emitting unit allows the function keys to transmit light, creating a lighting atmosphere and enabling the user to quickly identify the function keys and operate the sound card in a dark environment.

[0018] In one embodiment, a second light shielding member is provided on a side of the housing facing the accommodating cavity. The second light shielding member and the first circuit board enclose a mounting cavity, the second light-emitting unit is disposed in the mounting cavity, and at least a portion of the function keys are disposed in the mounting cavity. Providing the second light shielding member prevents the lighting atmospheres of the multiple function keys from interfering with each other, thereby enhancing the user experience.

[0019] In one embodiment, the sound card further includes a port assembly electrically connected to the first circuit board and configured to connect to the external device; the port assembly includes a headset interface having an insertion detection function. The headset interface not only allows the user to use a headset, but also quickly and automatically detects the type of headset inserted and automatically adjusts the audio signal input.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] See also Figure 1 and Figure 2 , showing two perspective views of the sound card 100 provided in an embodiment of the present application. The sound card 100 provided in an embodiment of the present application is used to connect to external devices to realize the mutual conversion of sound waves and digital signals, wherein the external devices include but are not limited to microphones, computers, tablets, mobile phones and other electronic devices.

[0036] See also Figure 3 and Figure 4 The sound card 100 includes a shell 10, a control component, a light-emitting component, and a light-guiding structure; wherein the shell 10 has a accommodating cavity 10a; the control component includes a first circuit board 21, which is arranged in the accommodating cavity 10a; the light-emitting component is arranged in the accommodating cavity 10a and is electrically connected to the first circuit board 21, and is used to emit light; the light-guiding structure is arranged in the shell 10, and is used to transmit the light emitted by the light-emitting component to the outside of the shell 10.

[0037] Compared with the existing technology, the sound card 100 provided in the present application adopts a light-guiding structure to transmit the light emitted by the light-emitting component to the outside of the shell 10, so that the user can observe the colorful light, create a better lighting atmosphere, and produce a strong visual effect; thereby, the user can enjoy the auditory effect while combining the visual effect, thereby creating a more three-dimensional atmosphere and improving the user experience.

[0038] Specifically, the light-guiding structure is provided in the shell 10, and may be connected to the shell 10 and provided on the shell 10, or provided in the accommodating cavity 10a in the shell 10, or part of the light-guiding structure may be provided on the shell 10 and part may be provided in the accommodating cavity 10a. This application does not impose any specific restrictions.

[0039] In this embodiment, the housing 10 includes a top shell 11 and a bottom shell 12. The top shell 11 and the bottom shell 12 are connected to form the accommodating cavity 10a. Specifically, the bottom shell 12 includes a bottom plate 121 and side plates. The side plates are arranged along the periphery of the bottom plate 121 and connected to the top shell 11. The side plates constitute the four side surfaces of the housing 10, and these four side plates are respectively defined as a first side plate 122, a second side plate 123, a third side plate 124, and a fourth side plate 125. The first side plate 122 and the fourth side plate 125 are arranged opposite each other and are located on the front and back sides of the housing 10. The second side plate 123 and the third side plate 124 are arranged opposite each other and are located on the left and right sides of the housing 10. The fourth side plate 125 is taller than the first side plate 122, thereby giving the sound card 100 a low front and high back shape.

[0040] In this embodiment, mounting holes 10b are defined between the side panels and the housing 11. Specifically, mounting holes 10b are defined between the first side panel 122, the second side panel 123, and the third side panel 124 and the housing 11. The light guide structure includes a first light guide 41, which is positioned within the mounting holes 10b. Positioning the first light guide 41 on the side of the housing 10 does not affect the operation of the sound card 100, while also providing a glare lighting effect, enhancing the user's visual experience.

[0041] In this embodiment, the first light guide 41 is a light-transmitting rubber strip. The first light guide 41 is inserted into the mounting hole 10b, and the portion exposed outside the housing 10 abuts the front shell 11 and the side panels, respectively. To better demonstrate the lighting effect, the first light guide 41 has a certain filtering property, which can filter out a portion of the light, selectively transmit the emitted light to the outside, and transmit light waves that the user can accept or prefer, thereby achieving a better effect. In this embodiment, the mounting hole 10b and the exposed portion of the first light guide 41 both have a U-shaped structure.

[0042] In one embodiment, the mounting hole 10b and the first light guide member 41 can be arranged on only one side surface of the shell 10, such as the side surface where the first side panel 122 or the second side panel 123 or the third side panel 124 is located; or they can be arranged on two sides of the shell 10, such as the first side panel 122 and the second side panel 123, or the first side panel 122 and the third side panel 124, or the two sides where the second side panel 123 and the third side panel 124 are located; this application does not impose any specific restrictions.

[0043] In other embodiments, the mounting hole 10b may be provided between the side panel and the bottom panel 121, or in the middle of the side panel. In another embodiment, the side panel may be entirely made of a light-transmitting material and serve as the first light guide 41 to connect the bottom panel 121 and the housing 11.

[0044] See also Figure 5 、 Figure 6 and Figure 7 and Figure 8 In this embodiment, the first light guide member 41 includes a main body 411, a first engaging portion 412, a limiting portion 413, and an abutting portion 414. The main body 411 abuts the front cover 11 and the side panel, and one side surface is exposed outside the housing 10. Specifically, the exposed outer surface of the main body 411 is flush with the outer surface of the side panel, making the product more beautiful and neat in appearance.

[0045] The first clamping portion 412 is provided on one side of the main body 411 and is clamped with the second clamping portion 111 on the face shell 11 , so that the first light guide member 41 and the face shell 11 are more firmly installed, and the structure is simple and easy to install.

[0046] The limiting portion 413 is provided on a side of the main body 411 away from the first clamping portion 412, and the limiting portion 413 is adjacent to or abuts the side panel; the abutting portion 414 is provided on the other side of the main body 411 and abuts the face shell 11; a deformation portion 415 is provided between the abutting portion 414 and the first clamping portion 412. Specifically, the deformation portion 415 is a groove, so that when the first clamping portion 412 is clamped with the second clamping portion 111, there is a certain deformation space, which can improve assembly efficiency and avoid damage to product components. The first clamping portion 412, the limiting portion 413 and the abutting portion 414 are all provided in the accommodating cavity 10a. The limiting portion 413 is adjacent to or abuts the side panel and extends from the main body 411 toward the bottom plate 121 , thereby limiting the first light guide member 41 within the accommodating cavity 10a and preventing it from being moved out of the mounting hole 10b , thereby ensuring the installation stability of the first light guide member 41 .

[0047] In order to ensure the connection stability between the first light guide 41 and the housing 10, please refer to Figure 5 , a third clamping portion 416 is further provided on the first light guide 41, specifically, the third clamping portion 416 is provided on the side of the abutting portion 414 facing the face shell 11, and a fourth clamping portion 112 is provided at a corresponding position on the face shell 11, and the third clamping portion 416 is clamped with the fourth clamping portion 112. In this embodiment, the first clamping portion 412 is a clamping block, the second clamping portion 111 is a clamping slot, the third clamping portion 416 is a clamping slot, and the fourth clamping portion 112 is a clamping block. In other embodiments, the first clamping portion 412 and the fourth clamping portion 112 may also be clamping slots, and the second clamping portion 111 and the third clamping portion 416 may be clamping blocks. This application does not impose any specific restrictions, as long as the two can be clamped.

[0048] See also Figure 7 The abutting portion 414 abuts against the face shell 11, and the side of the main body 411 and the limiting portion 413 facing the accommodating cavity 10a is an arc surface. In order to prevent the light emitted by the light-emitting component from being dissipated to the outside through other positions of the housing 10, and to achieve a better lighting atmosphere effect, in this embodiment, the light-guiding structure further includes a first light-shielding member 42. The first light-shielding member 42 is a baffle, which is disposed in the accommodating cavity 10a and connected to the face shell 11. It abuts against the abutting portion 414 of the first light-guiding member 41, thereby enclosing and forming a light-guiding cavity 10c. The light emitted by the light-emitting component is transmitted from the light-guiding cavity 10c to the outside of the housing 10 through the first light-guiding member 41.

[0049] Specifically, the light-emitting assembly includes a first light-emitting unit 31 electrically connected to the first circuit board 21. The first light-emitting unit 31 is disposed within the light-guiding cavity 10c. Light emitted by the first light-emitting unit 31 is transmitted to the outside of the housing 10 via the first light-guiding member 41. Placing the first light-emitting unit 31 within the light-guiding cavity 10c allows light emitted by the first light-emitting unit 31 to be directly transmitted out of the housing 10 via the first light-guiding member 41, thereby reducing energy loss.

[0050] In this embodiment, the first light-emitting unit 31 is arranged at the edge of the first circuit board 21, the first light-shielding member 42 abuts the first circuit board 21, and the end of the limiting portion 413 of the first light-guiding member 41 away from the first clamping portion 412 abuts the first circuit board 21. The edge of the first circuit board 21, the first light-shielding member 42 and the first light-guiding member 41 are enclosed to form the light-guiding cavity 10c. The light emitted by the first light-emitting unit 31 is transmitted to the outside of the housing 10 through the first light-guiding member 41. Specifically, the first light-emitting unit 31 is an LED lamp bead that can emit light of various colors. In other embodiments, the first light-emitting unit 31 can also be arranged on the side of the first light-shielding member 42 facing the light-guiding cavity 10c. Regarding the specific setting position of the first light-emitting unit 31, this application does not impose any specific restrictions, as long as it can achieve the goal of guiding light through the first light-guiding member 41.

[0051] Continue reading Figure 3 and Figure 7 In this embodiment, a limiting plate 13 is further provided on the bottom housing 12. A limiting groove 211 is correspondingly provided on the edge of the first circuit board 21. At least a portion of the limiting plate 13 extends into the limiting groove 211, thereby ensuring the correct installation of the first circuit board 21 and preventing wear or damage to other components due to movement after installation. In this embodiment, the size of the first circuit board 21 is roughly equivalent to that of the bottom plate 121.

[0052] In one embodiment, the edge of the first circuit board 21 may also directly abut the side panel, and the first light shielding member 42, the edge portion of the first circuit board 21, the side panel and the first light guide member 41 form the light guide cavity 10c.

[0053] In one embodiment, the first light-emitting unit 31 may also be disposed on an edge portion of the bottom plate 121 adjacent to the side plate, and the first light-shielding member 42, the edge portion of the bottom plate 121, the side plate, and the first light-guiding member 41 may collectively enclose the light-guiding cavity 10c. In a variation of this embodiment, the limiting portion 413 of the first light-guiding member 41 may also directly abut the bottom plate 121, so that the first light-guiding member 41, the bottom plate 121, and the first light-shielding member 42 enclose the light-guiding cavity 10c.

[0054] In one embodiment, the abutting portion 414 of the first light guide member 41 may not abut the first light shielding member 42, and the first light-emitting unit 31 may be provided on the housing 11. The housing 11, the first light shielding member 42, the first light guide member 41, the side panels, and the edge portion of the bottom plate 121 or the first circuit board 21 together form the light guide cavity 10c. In a variation of this embodiment, the limiting portion 413 of the first light guide member 41 may directly abut the bottom plate 121, so that the housing 11, the first light shielding member 42, the first light guide member 41, and the bottom plate 121 together form the light guide cavity 10c.

[0055] Continue reading Figure 3 and Figure 4 In this embodiment, the control assembly further includes function keys disposed within and exposed outside the housing 10 and electrically connected to the first circuit board 21. The function keys are used to adjust the amplification level of the signal input to the sound card 100 and / or the signal strength output by the sound card 100, and / or to enable or disable the mute function of the sound card 100. The provision of these function keys allows for better control or adjustment of the sound card 100, improving operational efficiency.

[0056] Specifically, the function keys include a button 221, a knob 222 and a fader 223. The function keys are all provided in the holes on the surface shell 11 and exposed to the outside of the housing 10 so that the user can operate them such as pressing, rotating, pushing and pulling. For ease of description and understanding, please refer to Figure 9In this embodiment, the face shell 11 is divided into four control areas: a first control area 1a, a second control area 1b, a third control area 1c, and a fourth control area 1d. The knob 222 is located in the first control area 1a, which is located near the fourth side panel 125 of the face shell 11. The fader 223 is located in the second control area 1b, which is located near the second side panel 123 of the face shell 11. Some buttons 221 are located in the third control area 1c, which is located near the third side panel 124 of the face shell 11. Some buttons 221 are located in the fourth control area 1d, which has two buttons located at opposite ends of the third control area 1c and are located near the first and fourth side panels 122 and 125 of the face shell 11, respectively. Specifically, the knob 222 protrudes the highest from the face shell 11, followed by the fader 223, and finally the button 221. By arranging the function keys in the four control areas on the housing 11 in this manner, the function keys on the housing 11 can be arranged in a staggered manner, so that they do not interfere with each other during use, making it easier for the user to distinguish and use them. For example, when it is necessary to rotate the knob 222, the user can directly find the highest first control area 1a and operate the knob 222; when it is necessary to push or pull the fader 223, the user can directly find the highest fader 223 on the second controller on the left and operate it; when it is necessary to press and operate, the user can directly find the lowest third control area 1c or fourth control area 1d.

[0057] In this embodiment, there are three knobs 222, two faders 223, and 13 buttons 221. Nine of the buttons 221 are arranged in a nine-square grid pattern in the third control area 1c, and the remaining four buttons 221 are arranged in pairs in the two fourth control areas 1d.

[0058] For ease of understanding, each function key will be briefly described in this embodiment.

[0059] The functions of the two faders 223 are to control the volume of the microphone or accompaniment connected to the sound card 100, such as one controls the volume of the XLR microphone, and the other controls the volume of the accompaniment audio of the Bluetooth input, 3.5mm input and USB-C downstream.

[0060] One knob 222 is used to control the gain of the microphone, such as controlling the gain of an XLR microphone; one knob 222 controls the Reverb reverberation, specifically, for example, controlling the strength of the reverberation effect, which is turned off when turned to the far left; one knob 222 controls the Headphones, specifically, for example, controlling the volume of the "headphone" and "headset" interfaces through the knob 222.

[0061] The buttons 221 located in the fourth control area 1d have the functions of controlling microphone mute, accompaniment mute, microphone power switch, opening and closing of the Bluetooth accompaniment connection function, etc.

[0062] The buttons 221 located in the third control area 1c have the functions of eliminating the original sound switch (ducking), monitoring switch (internal speaker switch), voice change mode, noise reduction function, glare mode (lighting mode of the first light-emitting unit 31), and 4 custom function buttons 221, which can customize the light brightness, recording, clearing recording and other functions.

[0063] In order to increase the glare effect and to be able to see the button 221 in a dark environment for user operation, the button 221 is light-transmitting, and the light-emitting component includes a second light-emitting unit 32 electrically connected to the first circuit board 21. The second light-emitting unit 32 is arranged in the accommodating cavity 10a and the light emitted is transmitted to the outside of the shell 10 through the function key. Specifically, the second light-emitting unit 32 is an LED lamp bead that can emit light of various colors. The second light-emitting unit 32 is arranged on the side of the first circuit board 21 facing the button 221. Since the number of buttons 221 is large, the number of the second light-emitting units 32 corresponds to the setting of the buttons 221, so that each button 221 can be light-transmitting.

[0064] See also Figure 3 and Figure 7 Because there are a large number of buttons 221 and second light-emitting units 32, and they are arranged adjacent to each other, a second light-shielding member 14 is provided on the side of the housing 11 facing the accommodating cavity 10a to prevent the light emitted by the second light-emitting unit 32 from affecting the lighting effects of other adjacent buttons 221. The second light-shielding member 14 acts as a baffle. Together with the first circuit board 21, the second light-shielding member 14 forms a mounting cavity 10d. The second light-emitting units 32 are located within this mounting cavity 10d, and at least a portion of the function keys are located within this mounting cavity 10d. In this embodiment, a portion of the structure of the button 221 is located between the second light-shielding member 14 and the first circuit board 21, thereby separating the two and preventing the second light-shielding member 14 from damaging the first circuit board 21. The second light-shielding member 14 confines the light emitted by the second light-emitting unit 32 to the mounting cavity 10d within which it is located. Thus, light emitted by the second light-emitting unit 32 can only be transmitted out of the housing 10 through the button 221 installed in this mounting cavity 10d.

[0065] By using the color of the light emitted by the second light-emitting unit 32, the button 221 can transmit light of different colors, so that the button 221 can show different colors when being pressed, and thus can also serve as an indicator. For example, the button 221 for controlling the mute of the microphone displays a red light effect after being pressed, indicating that the microphone has been muted. When the mute is pressed again, the red light effect on the button 221 disappears, indicating that the mute is released. Due to the large number of buttons 221, the relationship between the buttons 221 and the corresponding lighting effects is not listed one by one in this application. In this embodiment, the second light-emitting unit 32 can not only enable the button 221 to transmit different lighting effects, increase the lighting effects of the sound card 100, but also serve as a prompt, indicating the status of the corresponding function after the button 221 is pressed.

[0066] See also Figure 3 and Figure 4 In this embodiment, the control assembly further includes a first indicator light 23 electrically connected to the first circuit board 21 and a battery 24. The first indicator light 23 is disposed through the housing 11 and is used to display the battery 24 charge level. The battery 24 is disposed within the accommodating cavity 10a. In the sound card 100 provided in this embodiment, there are multiple first indicator lights 23, with five being used as an example. When the battery 24 charge level is greater than 75%, four first indicator lights 23 illuminate; when the battery 24 charge level is less than 75% but greater than or equal to 50%, three first indicator lights 23 illuminate; when the battery 24 charge level is less than 50% but greater than 25%, two first indicator lights 23 illuminate; and when the battery 24 charge level is less than or equal to 25%, one first indicator light 23 illuminates. In other embodiments, other indication formats may be employed, such as dividing the multiple first indicator lights 23 into four segments and displaying the current battery 24 charge level in a bar graph, representing the remaining charge levels of 20%, 40%, 60%, and 80% respectively. This application does not specifically limit the specific indication format.

[0067] In order to prevent the light emitted by the first indicator light 23 from affecting the lighting effects of the surrounding buttons 221, a third shading member 16 is further provided on the outside of the first indicator light 23. The third shading member 16 is arranged around the first indicator light 23 and abuts against the face shell 11 and the first circuit board 21. The first indicator light 23 is arranged on the first circuit board 21, thereby ensuring that the light of the first indicator light 23 can only be transmitted to the outside through the face shell 11.

[0068] Since the primary function of the faders 223 is to control the volume, in order to more intuitively display the volume adjustment status of the faders 223, in this embodiment of the present application, the control assembly also includes a second indicator light 25, which is electrically connected to the first circuit board 21. Specifically, the second indicator light 25 is located on the side of the first circuit board 21 facing the faceplate 11, adjacent to the faders 223. Specifically, the second indicator light 25 is located on the first circuit board 21 between the two faders 223. The second indicator light 25 is an LED bead that can emit light in various colors. A light-transmitting slit 11a is provided on the faceplate 11 at a position corresponding to the second indicator light 25, allowing light from the second indicator light 25 to be transmitted out of the faceplate 11 through the light-transmitting slit 11a. There are two second indicator lights 25, one corresponding to each of the two faders 223. The light emitted by the second indicator light 25 can indicate the volume level, such as the strength of the microphone or microphone signal, and can also indicate overload using different colors.

[0069] To soften the light emitted by the second indicator light 25, a second light guide 15 is provided within the light-transmitting slit 11a. This second light guide 15 is a light-transmitting rubber strip that transmits relatively soft light, making viewing more comfortable for the user. Furthermore, to prevent the light emitted by the second indicator light 25 from affecting the surrounding function keys, a fourth light shielding member 17 is provided between the face shell 11 and the first circuit board 21. This fourth light shielding member 17 surrounds the second indicator light 25, and the second light guide 15 is located on the side of the fourth light shielding member 17 facing the face shell 11, thereby directing the light emitted by the second indicator light 25 out of the face shell 11 through the second light guide 15.

[0070] See also Figure 2 、 Figure 3 and Figure 4 The sound card 100 includes a port assembly, which is electrically connected to the first circuit board 21 and is used to connect to the external device. Specifically, the port assembly includes a microphone interface 51, a headset interface 52, an accompaniment interface 53, a headphone interface 54, a linear output interface 55, a data interface 56, and a power interface 57. The port assembly is all installed in the opening of the fourth side panel 125.

[0071] The microphone interface 51 is a XLR or 6.35mm universal microphone interface, and supports dynamic microphone input with an XLR or 6.35mm plug.

[0072] The headset interface 52 supports mobile phone and gaming headset input with a 3.5mm TRRS plug; it has an insertion detection function, which automatically blocks the XLR signal input when a four-segment headset is inserted; if a three-segment headset or other non-headset device is inserted, the XLR / 6.35mm microphone interface 51 is still used as the audio input.

[0073] The accompaniment interface 53 is used to connect to the audio signal input of external audio devices such as mobile phones, tablet computers, decoders, players, etc.; it supports mobile phones, MP3 and other audio playback devices to transmit audio signals to the sound card 100 through the AUX audio line.

[0074] The headphone jack 54 supports mobile phone / game headsets (TRRS plug) and ordinary headphones (TRS plug), and after connecting to the sound card 100, the sound of each audio channel on the sound card 100 can be monitored.

[0075] The linear output interface 55 is a 3.5mm unidirectional stereo output interface for connecting to speakers and other audio devices.

[0076] The data interface 56 is a USB-C data interface 56 , which is used for uplink and downlink of audio signals; the data interface 56 can also be used as a power supply interface for the sound card 100 .

[0077] The power interface 57 is a DC power interface 57 for supplying power to the sound card 100 .

[0078] In this embodiment, when the headset interface 52 and the headphone interface 54 are used at the same time, both have sound output, thereby increasing the applicability of the sound card 100 product and enhancing the user experience.

[0079] In this embodiment, the control component further includes a switch key 28 , which is disposed in an opening of the fourth side panel 125 and is electrically connected to the first circuit board 21 for controlling the power on and off of the sound card 100 .

[0080] See also Figure 3 and Figure 4 To enhance the functionality and control of the sound card 100, in this embodiment, the control assembly further includes a second circuit board 26. The port assembly and the switch 28 are both electrically connected to the second circuit board 26, which is in turn electrically connected to the first circuit board 21. The second circuit board 26 provides better control of the port assembly, thereby providing enhanced sound quality. Specifically, the second circuit board 26 is disposed between the first circuit board 21 and the bottom plate 121, and is arranged parallel to the first circuit board 21.

[0081] To further enhance the sound quality of the microphone connected to the sound card 100, the control assembly is further provided with a third circuit board 27 electrically connected to the microphone interface 51. The third circuit board 27 is disposed between the second circuit board 26 and the bottom plate 121 and is electrically connected to the second circuit board 26. Providing a third circuit board 27 solely for the microphone interface 51 allows the audio signal input from the microphone to the sound card 100 to be better processed by the third circuit board 27, thereby outputting better sound quality and enhancing the user experience.

[0082] See also Figure 2 and Figure 4 In this embodiment of the present application, the bottom housing 12 is further provided with a mounting structure that can be detachably connected to a connection structure of an external device, thereby allowing the sound card 100 to be mounted on the external device, thereby supporting the sound card 100 and expanding its adaptability and application scenarios. Specifically, the mounting structure is a fastener 61 with internal threads, which ensures a secure installation and detachable connection, and provides better adaptability.

[0083] In other embodiments, the mounting structure may also be a buckle, a slot, or other detachable connection structure, as long as it can be detachably connected to an external device. This application does not impose any specific restrictions.

[0084] In order to prevent the sound card 100 from shaking or shifting during control, in this embodiment, an anti-slip pad 18 is further provided on the bottom plate 121, specifically a silicone pad. The silicone pad is provided with anti-slip grooves, which can increase the friction between the sound card 100 and an external supporting object such as a desktop, thereby ensuring that the sound card 100 can be prevented from shaking or shifting during use.
