Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to audio equipment, audio systems, and vehicles. Background Technology

[0002] Car speakers refer to speaker devices installed inside a vehicle. In the current technology, car speakers are generally fixed inside the vehicle, and the position of the sound source inside the speaker remains fixed. It is impossible to change the listening effect by changing the position of the sound source. In addition, they can only be used inside the car and cannot be taken out for separate use. If users need to use the audio outside the car, they often need to carry an additional portable independent speaker, which is extremely inconvenient and cannot meet the needs of customers to use audio outside the car.

[0003] Therefore, the inability of existing audio systems to meet users' needs for using audio systems outside the car is a problem that needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide a speaker that addresses the problem that existing speakers cannot meet the needs of users for using speakers outside of a vehicle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect of this application, an audio system is provided for a vehicle, including an audio body and a detachable connection portion, the detachable connection portion being disposed on the audio body and used for detachable connection with the vehicle's internal structure.

[0007] This application incorporates a detachable connecting part for detachable connection to the vehicle's internal structure. When a user needs to use the audio system inside the vehicle, the detachable connecting part can be connected to the vehicle's internal structure to secure the audio unit, facilitating user use. When a user needs to use the audio system outside the vehicle, the detachable connecting part can be removed from the vehicle's internal structure, allowing the audio unit to be moved outside the vehicle and used as an independent audio system, thus meeting the customer's need for using the audio system outside the vehicle.

[0008] In some embodiments of this application, the audio system further includes a plug-in housing, which forms a detachable connection portion. The plug-in housing is adapted to be inserted into a plug-in slot in a vehicle, and the audio system body is housed within the plug-in housing.

[0009] In this way, by setting up a plug-in housing, the plug-in housing can be plugged into the plug-in slot of the vehicle. This not only meets the customer's needs for using the audio system inside or outside the vehicle, but also houses the audio unit inside the plug-in housing. The plug-in housing can protect the audio unit and prevent it from being damaged by external forces.

[0010] In some embodiments of this application, the plug-in housing includes at least one sidewall, which is parallel to the plug-in direction of the plug-in housing; the sidewall is provided with at least one guide structure, the extension direction of the guide structure is consistent with the plug-in direction of the plug-in housing, and the guide structure is used to guide the plug-in housing to be plugged into the plug-in slot.

[0011] In this way, a guide structure is provided on at least one side wall of the plug-in housing. The guide structure can guide the plug-in housing to be inserted into the plug-in slot, so that the speaker body can slide along the plug-in direction. When it is necessary to remove the speaker body, the user only needs to slide the speaker in the opposite direction of the plug-in direction to remove the speaker from the plug-in slot of the vehicle, which improves the convenience of removing the speaker.

[0012] In some embodiments of this application, at least one sidewall includes a first sidewall and a second sidewall opposite to each other, and a third sidewall connected between the first sidewall and the second sidewall; the first sidewall, the second sidewall, and the third sidewall are all parallel to the insertion direction of the insertion housing, and at least two of the first sidewall, the second sidewall, and the third sidewall are provided with guide structures.

[0013] Thus, at least two of the first, second, and third side walls are provided with guide structures. Multiple guide structures can make the speaker body more stable when sliding in the vehicle's locking slot, and can also prevent the speaker from shaking during vehicle operation, which could lead to speaker damage.

[0014] In some embodiments of this application, the guide structure includes a guide groove, which is open at the front end and closed at the rear end along the insertion direction of the insertion housing.

[0015] In this way, by opening the front end and closing the rear end of the guide groove, the speaker can slide along the insertion direction of the plug-in housing, and the vehicle's locking structure enters the guide groove from the front end until it stops at the rear end of the guide groove, which can prevent the speaker from being misaligned.

[0016] In some embodiments of this application, the width of the guide groove gradually increases along the insertion direction of the insertion housing.

[0017] As the guide groove gradually increases in width, the speaker slides along the insertion direction, allowing the guide groove to make increasingly tighter contact with the vehicle's internal structure, thus enabling the speaker to be installed more stably in the vehicle's mounting slot.

[0018] In some embodiments of this application, the outer surface of the sidewall is provided with a slot, which is suitable for engaging a locking mechanism inside the vehicle.

[0019] In this way, when the locking mechanism inside the vehicle is not engaged with the slot, the speaker can be removed from the slot. When the speaker is engaged with the slot, the locking mechanism engages with the slot to limit the speaker's movement and prevent it from being damaged.

[0020] In some embodiments of this application, the inner surface of the slot includes a sloped region, and the direction of inclination of the sloped region intersects the orthographic projection direction of the outer surface of the sidewall with the insertion direction of the insertion housing.

[0021] In this way, by making the projection direction of the inclined area onto the outer surface of the side wall intersect with the insertion direction of the plug-in housing, the gravity acting on the locking mechanism by the speaker can be decomposed into a horizontal force and a vertical force, so that the speaker is subjected to force in both the horizontal and vertical directions, thus preventing the speaker from shaking.

[0022] In some embodiments of this application, the inclined region includes a first inclined region and a second inclined region facing each other, and at least one of the first inclined region and the second inclined region is adapted to contact the locking mechanism; the arrangement direction of the first inclined region and the second inclined region intersects with the insertion direction of the insertion housing.

[0023] In this way, the first and second inclined areas are suitable for contact with the locking mechanism, which can make the locking mechanism and the slot fit tightly, making the speaker more stable in the slot and preventing the speaker from shaking.

[0024] In some embodiments of this application, at least one sidewall includes a fourth sidewall, which is connected between the first sidewall and the second sidewall and is disposed opposite to the third sidewall. The outer surface of the fourth sidewall is provided with a handle.

[0025] In this way, by setting up a handle, users can install or remove the audio system from the vehicle's interior, improving the convenience of using the audio system.

[0026] In some embodiments of this application, the outer surface of the fourth sidewall is provided with a groove, the two ends of the handle are respectively provided on opposite sides of the groove, and there are gaps between the middle part of the handle and the bottom surface of the groove, as well as between the middle part of the handle and the opposite sides of the groove.

[0027] Thus, when the user grips the handle, the groove on the outer surface of the fourth side wall can accommodate the user's fingers, allowing the user to grip the handle more stably and improving the user's experience.

[0028] In some embodiments of this application, the speaker also includes a control button group, including at least one control button. The control button group is disposed in the plug-in housing and electrically connected to the speaker body to input or output control signals to the speaker body.

[0029] In this way, users can control the speaker unit through the control button group, so that the speaker unit can meet the user's different needs.

[0030] In some embodiments of this application, along the insertion direction of the plug-in housing, the front end of the plug-in housing includes a front end wall; the speaker also includes an external terminal and a protective cover, the external terminal is disposed on the front end wall, the external terminal is electrically connected to the speaker body, and the protective cover can switch between a first position and a second position. When the protective cover is in the first position, the protective cover closes the external terminal, and when the protective cover is in the second position, the protective cover opens the external terminal.

[0031] In this way, users can interact with the audio system through the external terminal to input or output signals. The external terminal can be connected to the vehicle's infotainment system, as well as to a mobile phone or computer, to meet the needs of the audio system in different states. The protective cover can protect the external terminal, preventing other objects from impacting the interface or debris from entering the external terminal, which would affect the normal use of the external terminal and extend its service life.

[0032] In some embodiments of this application, an external port is formed at the front end of the external terminal along the insertion direction of the plug housing; when the protective cover is in the first position, the protective cover closes the external port, and when the protective cover is in the second position, the protective cover opens the external port.

[0033] In this way, by setting a protective cover at the external port, the first port can be opened when the external port needs to be used, and the first port can be closed when the external port does not need to be used. The protective cover can protect the external port, prevent other objects from impacting the interface or debris from entering the external port, which would affect the normal use of the external port and improve the service life of the external port.

[0034] In some embodiments of this application, the protective cover is rotatably connected to the front end wall, and the protective cover is rotatable relative to the front end wall to switch between a first position and a second position.

[0035] This allows the protective cover to rotate relative to the front wall, improving the convenience of opening or closing the external port and preventing the protective cover from being lost or nowhere to be stored when the external port is opened.

[0036] In some embodiments of this application, along the insertion direction of the plug-in housing, the rear end of the plug-in housing is provided with an opening, and the speaker also includes a cabinet grille provided at the opening, with the sound output end of the speaker body facing the cabinet grille.

[0037] In this way, compared to solid sidewalls, the enclosure grille can reduce the impact on the sound propagation of the speaker body. The enclosure grille can also protect the speaker body, preventing other objects from impacting the interface or debris from entering the speaker body and affecting its normal use.

[0038] In some embodiments of this application, the inner wall of the plug-in housing is provided with a reinforcing structure, and the speaker body is connected to the reinforcing structure.

[0039] In this way, the reinforced structure can connect the snap-fit ​​housing to the speaker body, improve the connection strength between the speaker body and the snap-fit ​​housing, and make the speaker body more stably housed in the snap-fit ​​housing.

[0040] In some embodiments of this application, the audio body includes at least one speaker, a control circuit board, and a battery.

[0041] In this way, when the audio system is used outside the car, the battery can power the audio system itself, eliminating the need to connect the audio system to other external power sources, thus improving the convenience of using the audio system for users.

[0042] In some embodiments of this application, at least one speaker includes one or more of a tweeter, a midrange speaker, and a woofer.

[0043] In this way, tweeters, midrange speakers, and woofers can improve the overall sound quality of the audio system to meet different user needs and enhance its versatility.

[0044] In some embodiments of this application, the speaker body further includes an antenna transmitting and receiving module, which is electrically connected to the control circuit board.

[0045] In some embodiments of this application, the antenna transmitting and receiving module is configured to receive wireless signals to transmit the wireless signals to a speaker via a control circuit board.

[0046] In some embodiments of this application, the wireless signals received by the antenna transmitting and receiving module include at least one of the wireless signals transmitted by the vehicle, the wireless signals transmitted by the terminal device, and the wireless signals transmitted by the sound-emitting device.

[0047] It should be noted that when the audio system is taken out of the vehicle, it can be connected and paired with the vehicle via Bluetooth or Wi-Fi. The wireless signal emitted by the vehicle is received by the antenna transmitter and receiver module, which converts the received wireless signal into an audio signal. The audio signal is then transmitted to the speaker via the control circuit board for audio playback.

[0048] When the speaker is taken out of the vehicle, it can be paired with wireless devices such as mobile phones or computers via Bluetooth or Wi-Fi. The wireless signal emitted by the wireless device is received by the antenna transmitter and receiver module, which converts the received wireless signal into an audio signal. The audio signal is then transmitted to the speaker through the control circuit board for audio playback. This allows users to use the speaker as an independent audio system without having to carry extra speakers, meeting different user needs and improving the user experience.

[0049] The speaker can also receive wireless signals from other sound-emitting devices, which can be the same speaker or different speakers. After networking with other sound-emitting devices, it enters a broadcast mode, allowing users to play any audio through the network. All audio within the network will be broadcast simultaneously. Multiple speakers can also be cascaded to achieve a large-scale broadcast mode, meeting the needs of users in large-scale events and improving the user experience.

[0050] In some embodiments of this application, the plug-in housing encloses a receiving cavity, the volume of which is not less than 6.5L.

[0051] In a second aspect of this application, an audio system is provided, comprising: the aforementioned audio speaker and an audio mounting assembly, the audio mounting assembly being adapted to mount the audio speaker in a vehicle interior.

[0052] In some embodiments of this application, the audio mounting assembly includes a locking mechanism adapted to engage with a slot to engage the audio speaker.

[0079] Car speakers refer to speaker devices installed inside a vehicle. In the current technology, car speakers are generally fixed inside the vehicle, and the position of the sound source inside the speaker remains fixed. It is impossible to change the listening effect by changing the position of the sound source. In addition, they can only be used inside the car and cannot be taken out for separate use. If users need to use the speakers outside the car, they often need to carry an additional portable independent speaker, which is extremely inconvenient and cannot meet the needs of customers to use the speakers outside the car.

[0080] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0081] To achieve the above objectives, the present invention adopts the following technical solution:

[0082] Figure 1 This is a schematic diagram of the vehicle structure provided in an embodiment of this application. Figure 2 This is a schematic diagram of the internal structure of a vehicle provided in an embodiment of this application. This application provides a vehicle 1000, which can be a fuel-powered vehicle, a new energy vehicle, or a hybrid vehicle. The vehicle 1000 includes a body 300 and drive wheels 200.

[0083] The drive wheel 200 can drive the body 300 to move. The body 300 is provided with a connector slot, and the connector slot is equipped with a speaker. The speaker provided in this application can be stably connected to the connector slot, so as to avoid the speaker from colliding with the body 300 when the vehicle is driving on a bumpy road, which would cause damage to the speaker.

[0084] The vehicle 1000 also includes an audio system, which includes a signal transmission port and a signal transmission module. The signal transmission port is used to connect to the audio system 100 via a data transmission line, and the signal transmission module is used to transmit signals to the audio system 100.

[0085] The audio system 100 can be installed in the vehicle's trunk, under the seats, or on the center console, etc., and this application does not limit this.

[0086] like Figure 3 and Figure 4 As shown, an audio system 100 is provided for use in a vehicle 1000. It includes an audio system body 10 and a detachable connecting part. The detachable connecting part is disposed on the audio system body 10 and is used for detachable connection with the internal structure of the vehicle.

[0087] This application provides a detachable connecting part for detachable connection with the vehicle's internal structure. When a user needs to use the audio system 100 inside the vehicle, the detachable connecting part can be connected to the vehicle's internal structure to fix the audio system 10, making it convenient for the user to use. When a user needs to use the audio system 100 outside the vehicle, the detachable connecting part can be removed from the vehicle's internal structure, and the audio system 10 can be moved outside the vehicle, allowing the audio system 100 to be used as an independent audio system, thus meeting the customer's need to use the audio system 100 outside the vehicle.

[0088] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the audio system 100 also includes a plug-in housing 20, which forms a detachable connection portion. The plug-in housing 20 is adapted to be plugged into a plug-in slot in a vehicle, and the audio system body 10 is housed within the plug-in housing 20.

[0089] Thus, by setting up the plug-in housing 20, the plug-in housing 20 is plugged into the plug-in slot of the vehicle, which not only meets the customer's need to use the audio 100 inside or outside the vehicle, but also houses the audio body 10 inside the plug-in housing 20. The plug-in housing 20 can protect the audio body 10 and prevent it from being damaged by external forces.

[0090] In some embodiments of this application, such as Figure 3 and Figure 5 As shown, the plug-in housing 20 includes at least one side wall, which is parallel to the plug-in direction of the plug-in housing 20; the side wall is provided with at least one guide structure 211, the extension direction of the guide structure 211 is consistent with the plug-in direction of the plug-in housing 20, and the guide structure 211 is used to guide the plug-in housing 20 to be plugged into the plug-in slot.

[0091] In this way, a guide structure 211 is provided on at least one side wall of the plug-in housing 20. The guide structure 211 can guide the plug-in housing 20 to be inserted into the plug-in slot, so that the speaker body 10 can slide along the plug-in direction. When it is necessary to remove the speaker body 10, the user only needs to slide the speaker 100 in the opposite direction of the plug-in direction to disengage the speaker 100 from the plug-in slot of the vehicle, which improves the convenience of the user to remove the speaker 100.

[0092] In addition, the sidewall may not be parallel to the insertion direction of the insertion housing 20, that is, the sidewall may be a slope or a wave surface, and this application does not limit this.

[0093] In some embodiments of this application, such as Figure 3 , Figure 4 and Figure 12 As shown, at least one sidewall includes a first sidewall 21 and a second sidewall 22 opposite to each other, and a third sidewall 23 connected between the first sidewall 21 and the second sidewall 22; the first sidewall 21, the second sidewall 22 and the third sidewall 23 are all parallel to the insertion direction of the insertion housing 20, and at least two of the first sidewall 21, the second sidewall 22 and the third sidewall 23 are provided with a guide structure 211.

[0094] The guide structure 211 may be provided in the first side wall 21, the second side wall 22 and the third side wall 23, or in the first side wall 21 and the second side wall 22, or in the first side wall 21 and the third side wall 23, or in the second side wall 22 and the third side wall 23. This application does not limit the scope of the application.

[0095] Thus, at least two of the first sidewall 21, the second sidewall 22 and the third sidewall 23 are provided with guide structures 211. Multiple sets of guide structures 211 can make the speaker body 10 more stable when sliding in the vehicle's locking groove, and can also prevent the speaker 100 from shaking during vehicle operation, which could lead to damage to the speaker 100.

[0096] In some embodiments of this application, such as Figure 3 and Figure 5 As shown, the guide structure 211 includes a guide groove 2111. Along the insertion direction of the insertion housing 20, the front end of the guide groove 2111 is open and the rear end is closed.

[0097] In this way, the front end of the guide groove 2111 is open and the rear end is closed, allowing the audio 100 to slide along the insertion direction of the insertion housing 20. This allows the vehicle's locking structure to enter the guide groove 2111 from the front end until it stops at the rear end of the guide groove 2111, thus preventing the audio 100 from becoming misaligned.

[0098] In some embodiments of this application, the guide structure 211 may include two guide grooves 2111, namely a first guide groove 2111 and a second guide groove 2111, which are arranged parallel to each other at intervals.

[0099] In this way, by arranging the first guide groove 2111 and the second guide groove 2111 in parallel at intervals, the force on the speaker 100 can be more even, and the speaker 100 can remain stable in the vehicle's locking groove.

[0100] In some embodiments of this application, the width of the guide groove 2111 gradually increases along the insertion direction of the insertion housing 20.

[0101] As a result, the width of the guide groove 2111 gradually increases. When the speaker 100 slides along the insertion direction, the guide groove 2111 can make closer contact with the internal structure of the vehicle, so that the speaker 100 can be installed more stably in the vehicle's snap-fit ​​groove.

[0102] In some embodiments of this application, such as Figure 3 and Figure 5 As shown, the outer surface of the side wall is provided with a slot 212, which is suitable for engaging the locking mechanism inside the vehicle.

[0103] In this way, when the locking mechanism inside the vehicle is not engaged with the slot 212, the speaker 100 can be removed from the slot of the vehicle. When the speaker 100 is engaged with the slot of the vehicle, the locking mechanism engaged with the slot 212 can limit the speaker 100, preventing the speaker 100 from shaking in the slot of the vehicle and causing damage to the speaker 100.

[0104] In some embodiments of this application, the inner surface of the slot 212 includes a sloped region, and the direction of inclination of the sloped region is projected onto the outer surface of the sidewall and intersects with the insertion direction of the insertion housing 20.

[0105] Wherein, the direction of the inclination of the cross, excluding the inclined area, is projected onto the outer surface of the side wall in a direction perpendicular to the insertion direction of the insertion housing 20.

[0106] In this way, by making the projection direction of the inclined area on the outer surface of the side wall intersect with the insertion direction of the insertion housing 20, the gravity of the speaker 100 acting on the locking mechanism can be decomposed into a horizontal force and a vertical force, so that the speaker 100 is subjected to force in both the horizontal and vertical directions, thus preventing the speaker 100 from shaking.

[0107] In some embodiments of this application, such as Figure 3 , Figure 6 and Figure 7 As shown, the inclined region includes a first inclined region 2121 and a second inclined region 2122 facing each other. At least one of the first inclined region 2121 and the second inclined region 2122 is adapted to contact the locking mechanism. The arrangement direction of the first inclined region 2121 and the second inclined region 2122 intersects the insertion direction of the insertion housing 20.

[0108] Wherein, the intersection does not include the first inclined surface region 2121 and the second inclined surface region 2122 whose arrangement direction is perpendicular to the insertion direction of the insertion housing 20.

[0109] When locking the speaker, the locking mechanism may contact only the first inclined surface region 2121, or only the second inclined surface region 2122, or both the first inclined surface region 2121 and the second inclined surface region 2122.

[0110] In this way, the first inclined surface area 2121 and the second inclined surface area 2122 are suitable for contacting the locking mechanism, which can make the locking mechanism and the slot 212 fit tightly, making the speaker 100 more stable in the slot and preventing the speaker 100 from shaking.

[0111] In some embodiments of this application, such as Figure 3 and Figure 8 As shown, at least one sidewall includes a fourth sidewall 24, which is connected between the first sidewall 21 and the second sidewall 22, and is disposed opposite to the third sidewall 23. The outer surface of the fourth sidewall 24 is provided with a handle 241.

[0112] The handle 241 can be made of metal or plastic, and anti-slip grooves can be provided on the surface of the handle 241. This application does not limit this.

[0113] In this way, by setting the handle 241, the user can install or remove the audio system 100 into or out of the vehicle's internal structure, improving the user's convenience in using the audio system 100.

[0114] In some embodiments of this application, such as Figure 3 and Figure 8 As shown, the outer surface of the fourth sidewall 24 is provided with a groove 242, and the two ends of the handle 241 are respectively provided on the opposite sides of the groove 242. There are gaps between the middle part of the handle 241 and the bottom surface of the groove 242, and between the middle part of the handle 241 and the opposite sides of the groove 242.

[0115] Thus, when the user grips the handle 241, the groove 242 on the outer surface of the fourth side wall 24 can accommodate the user's fingers, allowing the user to grip the handle 241 more stably and improving the user's experience.

[0116] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the audio system 100 also includes a control button group 30, which includes at least one control button. The control button group 30 is located in the plug-in housing 20 and is electrically connected to the audio system 10 to input or output control signals to the audio system 10.

[0121] In some embodiments of this application, such as Figure 3 , Figure 9 and Figure 10As shown, along the insertion direction of the insertion housing 20, the front end of the insertion housing 20 includes a front end wall 25; the speaker 100 also includes an external terminal 251 and a protective cover 252. The external terminal 251 is disposed on the front end wall 25 and is electrically connected to the speaker body 10. The protective cover 252 can switch between a first position and a second position. When the protective cover 252 is in the first position, the protective cover 252 closes the external terminal 251. When the protective cover 252 is in the second position, the protective cover 252 opens the external terminal 251.

[0122] The external terminal 251 can be an audio analog interface, a CAN interface controller LAN interface, a charging interface, a power enable interface, a USB type-A interface, a USB type-C interface, etc.

[0123] It should be noted that the audio analog interface is used to connect to the vehicle's audio system. When the speaker 100 is fixed in the vehicle and the audio analog interface is turned on, the speaker 100 is used as a passive speaker 100. The low-frequency signal of the speaker 100 system can be emitted through the speaker 11 inside the speaker 100.

[0124] The CAN interface is used to exchange commands with the audio system and can synchronize diagnostic information, such as whether the microphone is paired and whether the audio system is in the vehicle.

[0126] The power enable interface is used to enable charging when the speaker 100 meets the charging conditions.

[0127] USB Type-A and USB Type-C can be used to transmit audio data or charge / discharge the device when the audio system is outside the vehicle.

[0128] In this way, users can interact with the audio system 100 through the external terminal 251 to input or output signals. The external terminal 251 can be connected to the vehicle's audio system, and it can also be connected to a mobile phone or computer to meet the needs of the audio system 100 in different states. The protective cover 252 can protect the external terminal 251, preventing other objects from impacting the interface or debris from entering the external terminal 251, which would affect the normal use of the external terminal 251 and improve its service life.

[0129] In some embodiments of this application, the front end of the external terminal 251 forms an external port along the insertion direction of the insertion housing 20; when the protective cover 252 is in the first position, the protective cover 252 closes the external port, and when the protective cover 252 is in the second position, the protective cover 252 opens the external port.

[0130] In this way, by setting a protective cover 252 at the external port, the first port can be opened when the external port needs to be used, and the first port can be closed when the external port does not need to be used. The protective cover 252 can protect the external port, prevent other objects from impacting the interface or debris from entering the external port, affecting the normal use of the external port, and improving the service life of the external port.

[0131] In some embodiments of this application, the protective cover 252 is rotatably connected to the front end wall 25, and the protective cover 252 is rotatable relative to the front end wall 25 to switch between a first position and a second position.

[0132] This allows the protective cover 252 to rotate relative to the front wall 25, improving the convenience of opening or closing the external port and preventing the protective cover 252 from being lost or left unattended when the external port is opened. In some embodiments of this application, the plug-in housing encloses a receiving cavity with a cavity volume of not less than 6.5L.

[0133] The volume of the receiving cavity can be 6.5L, 7L, 7.5L, 8L or 8.5L, etc., and this application does not limit it.

[0134] Thus, the cavity volume is no less than 6.5L, which can meet the requirements of acoustic low frequency extension down to 20Hz, ensuring that the audio 100 does not resonate when working at high power, and improving the user experience.

[0135] In some embodiments of this application, such as Figure 3 and Figure 11 As shown, along the insertion direction of the insertion housing 20, the rear end of the insertion housing 20 is provided with an opening. The speaker 100 also includes a cabinet grille 26, which is provided at the opening, and the sound output end of the speaker body 10 faces the cabinet grille 26.

[0136] In this way, compared with solid sidewalls, the enclosure grille 26 can reduce the impact on the volume propagation of the speaker body 10. The enclosure grille 26 can also protect the speaker body 10, preventing other objects from impacting the interface or debris from entering the speaker body 10 and affecting the normal use of the speaker body 10.

[0137] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the inner wall of the plug-in housing 20 is provided with a reinforcing structure 27, and the speaker body 10 is connected to the reinforcing structure 27.

[0138] In this way, the reinforcing structure 27 can connect the snap-fit ​​housing to the speaker body 10, improve the connection strength between the speaker body 10 and the snap-fit ​​housing, and make the speaker body 10 more stably housed in the snap-fit ​​housing.

[0139] In some embodiments of this application, such as Figure 3 and Figure 12 As shown, the audio body 10 includes at least one speaker 11, a control circuit board 12, and a battery 13; the speaker 11 is connected to the control circuit board 12, and the control circuit board 12 is connected to the battery 13.

[0140] Among them, the battery 13 can be an automotive-grade battery 13. This type of battery 13 can work normally in a temperature range of -40 to +85 degrees Celsius. When the audio 100 is used to power the audio system 100 when it is working outside the vehicle, it can provide power for 10 hours, thereby improving the applicability of the audio system 100 when it is used as a standalone audio system 100.

[0141] Thus, when the speaker 100 is used outside the vehicle, the battery 13 can power the speaker body 10 without connecting the speaker 100 to other external power sources, thus improving the convenience of using the speaker 100.

[0142] In some embodiments of this application, such as Figure 3 , Figure 12 and Figure 13 As shown, at least one speaker 11 includes a tweeter 111, a midrange speaker 112 and a woofer 113.

[0143] In this way, the tweeter 111, midrange speaker 112 and woofer 113 can improve the overall sound quality of the speaker 100 to meet the different needs of users and improve the applicability of the speaker 100.

[0144] In some embodiments of this application, at least one speaker 11 may include two tweeters 111, two midrange speakers 112 and one woofer 113 to meet different user needs.

[0145] In some embodiments of this application, the audio body 10 also includes an antenna transmitting and receiving module, which is electrically connected to the control circuit board 12.

[0146] In some embodiments of this application, the antenna transmitting and receiving module is configured to receive wireless signals to transmit the wireless signals to the speaker 11 via the control circuit board 12.

[0147] In some embodiments of this application, the wireless signals received by the antenna transmitting and receiving module include at least one of the wireless signals transmitted by the vehicle, the wireless signals transmitted by the terminal device, and the wireless signals transmitted by the sound-emitting device.

[0148] It should be noted that when the audio system is taken out of the vehicle 1000, the vehicle 1000 can be connected and paired with the audio system 100 via Bluetooth or Wi-Fi. The wireless signal emitted by the vehicle is received by the antenna transmitter and receiver module, and then transmitted to the speaker 11 through the control circuit board 12 for audio playback.

[0149] When the speaker is taken out of the vehicle 1000, it can be connected and paired with a wireless terminal such as a mobile phone or computer via Bluetooth or Wi-Fi. The wireless signal emitted by the wireless terminal is received by the antenna transmitting and receiving module, and then transmitted to the speaker 11 through the control circuit board 12 for audio playback. This allows users to use the speaker 100 as an independent speaker without having to carry an extra speaker, meeting different user needs and improving the user experience.

[0150] The speaker 100 can also receive wireless signals from other sound-emitting devices, which can be the same speaker or different speakers. After networking with other sound-emitting devices, it enters a broadcast mode, allowing users to play any audio through the network. All audio within the network can be played simultaneously. Multiple speakers 100 can also be cascaded to achieve a large-scale broadcast mode, meeting the needs of users in large-scale events and improving the user experience.

[0151] In some embodiments of this application, the audio body 10 further includes a signal processing module, which is electrically connected to the control circuit board 12.

[0152] In some embodiments of this application, the signal processing module is configured to process the signal received by the external terminal 251 when the external terminal 251 is connected to the vehicle 1000, convert the signal into a sound signal, and transmit the sound signal to the speaker 11 through the control circuit board 12.

[0153] In this way, the audio system 100 can amplify the sound in the vehicle to meet the needs of different users.

[0154] In some embodiments of this application, the signal processing module transmits the sound signal to the subwoofer 113 via the control circuit board 12.

[0155] Thus, when in the first mode, the speaker 100 can act as a subwoofer for the audio system, improving the overall sound quality of the audio system without the need for other subwoofers in the vehicle, thereby increasing the usable space inside the vehicle.

[0156] The above are merely specific embodiments 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.
