A vehicle music control system according to a preferred embodiment of the present invention will be disclosed and described in the following description with reference to fig. 1 to 11 of the drawings, wherein the vehicle music control system includes a control unit 10 and at least one seat device 20, the seat device 20 includes a seat body 21, a headrest 22, and two speaker assemblies 23, the headrest 22 is mounted on top of a backrest 211 of the seat body 21, opposite sides of the headrest 22 have fitting grooves 221, respectively, each of the speaker assemblies 23 is suspended from each of the fitting grooves 221 of the headrest 22, respectively, and each of the speaker assemblies 23 is controllably connected to the control unit 10, respectively, to control an angle of the speaker assemblies 23 within the fitting grooves 221 of the headrest 22 by the control unit 10.
Unlike prior art car audio seats that require adjustment of the angle of the speakers by swinging the wings laterally or longitudinally, in this particular example of the vehicle music control system of the present invention, the speaker assemblies 23 are suspended within the mounting slots 221 of the headrest 22 and the angle of the speaker assemblies 23 within the mounting slots 221 of the headrest 22 is adjustable, so that the control unit 10, when controlling the angular adjustment of the speaker assemblies 23 relative to the headrest 22, on the one hand, the two speaker assemblies 23 can form a preferred listening position at the head of the user for the user to hear a good sound effect, and on the other hand, the basic form of the seat arrangement 20 is not changed, so that the seat arrangement 20 does not therefore create a safety hazard, which is critical to driving safety.
That is, in the vehicle music control system of the present invention, the headrest 22 is fixed, the overall posture thereof does not need to be adjusted, only the angle of the speaker assembly 23 in the fitting groove 221 of the headrest 22 needs to be adjusted, and therefore the basic form of the seat apparatus 20 is not changed, so that the seat apparatus 20 does not thus create a safety hazard.
In order that the control unit 10 can conveniently adjust the angle of the speaker assembly 23, the control unit 10 includes an air charge and discharge control module 11, the seat device 20 includes an air charge and discharge assembly 24 and at least four air bags 25 connected to the air charge and discharge assembly 24 in an air charge and discharge manner, the air charge and discharge assembly 24 is controllably connected to the air charge and discharge control module 11, wherein at least two air bags 25 are respectively provided between each speaker assembly 23 and the bottom of each fitting groove 221 of the headrest 22, and one side of each air bag 25 is fixedly connected to the bottom of the fitting groove 221 of the headrest 22, and the other side is fixedly connected to the bottom of the speaker assembly 23.
That is, the speaker assembly 23 may be suspended in the fitting groove 221 of the headrest 22 by providing at least two of the airbags 25 between the groove bottom of the fitting groove 221 of the headrest 22 and the speaker assembly 23. In addition, the inflation/deflation control module 11 of the control unit 10 controls the working state of the inflation/deflation assembly 24, so that by changing the inflation amounts of the airbags 25, the angle of the speaker assemblies 23 in the assembly groove 221 of the headrest 22 can be adjusted, so that the two speaker assemblies 23 can form a better listening position on the head of the user for the user to hear good sound effects.
It is to be noted that the specific manner in which one side of the airbag 25 is fixedly coupled to the bottom of the fitting groove 221 of the headrest 22 is not limited in the vehicular music control system of the present invention. For example, in this specific example of the vehicular music control system shown in fig. 1 to 11, one side of the air bag 25 is adhered to the bottom of the fitting groove 221 of the headrest 22 by glue, so that one side of the air bag 25 is fixedly attached to the bottom of the fitting groove 221 of the headrest 22.
It is also worth mentioning that the specific way in which one side of the airbag 25 is fixedly connected to the speaker assembly 23 is not limited in the vehicle music control system of the present invention. For example, in this specific example of the vehicle music control system shown in fig. 1 to 11, one side of the air bag 25 is adhered to the bottom of the speaker assembly 23 by glue so that one side of the air bag 25 is fixedly connected to the bottom of the speaker assembly 23.
Specifically, in this specific example of the vehicle music control system according to the present invention, referring to fig. 3, 4, and 6 to 11, the speaker assembly 23 includes a housing 231 and a speaker unit 232, the housing 231 having a housing space 2311, the speaker unit 232 being mounted to the housing space 2311 of the housing 231, wherein one side of the air bag 25 is adhered to the bottom of the housing 231 by glue such that one side of the air bag 25 is fixedly connected to the bottom of the speaker assembly 23. With such a structure as described above, in the process of bonding the airbag 25 and the bottom of the speaker assembly 23 using glue, the glue is prevented from flowing into the inside of the speaker unit 232 by the housing 231 to ensure that the movable portion of the speaker unit 232 is not stuck by the glue to ensure the sound quality of the speaker assembly 23. Preferably, sound absorbing cotton is disposed in the housing space 2311 of the housing 231.
Preferably, the bottom of the housing 231 of the speaker assembly 23 has at least two fitting grooves 2312, and a portion of the air bag 25 is inserted into the fitting grooves 2312 of the housing 231 to secure reliability of the bonding relationship of the air bag 25 and the housing 231.
Preferably, four air bags 25 are disposed between the bottom of the fitting groove 221 of the headrest 22 and the bottom of the housing 231 of the speaker assembly 23 at intervals, and since each air bag 25 can be individually inflated and deflated, the angle of the speaker assembly 23 within the fitting groove 221 of the headrest 22 can be flexibly and multi-directionally adjusted to meet the listening needs of users in different sitting postures and to meet the listening needs of different users. Accordingly, the bottom of the housing 231 of the speaker assembly 23 has four fitting grooves 2312 for receiving portions of the four air bags 25, respectively.
More preferably, the housing 231 of the speaker assembly 23 is a square column-shaped housing, and four air bags 25 are respectively provided at four corners of the housing 231, so that the angle of the speaker assembly 23 within the fitting groove 221 of the headrest 22 can be flexibly and multidirectional adjusted by controlling the inflation amount of each air bag 25.
It is to be noted that the shape of the airbag 25 is not limited in the vehicle music control system of the invention. For example, in this specific example of the vehicle music control system of the present invention shown in fig. 1 to 11, the air bag 25 is a square column-shaped air bag so as to control the posture of the speaker assembly 23 in the fitting groove 221 of the headrest 22. Alternatively, in other examples of the vehicle music control system of the present invention, the air bag 25 may be cylindrical or spherical.
Referring to fig. 5, the inflation and deflation assembly 24 includes a plurality of inflators 241 and a plurality of normally closed solenoid valves 242, each of the inflators 241 and each of the solenoid valves 242 being controllably connected to the inflation and deflation control module 11, respectively, to control the operation of the inflators 241 and the operation of the solenoid valves 242 by the inflation and deflation control module 11, and the inflators 241 and the solenoid valves 242 being connected to the air bags 25, respectively. When the inflation/deflation control module 11 controls the inflation pump 241 to be in an operating state and the electromagnetic valve 242 to be in a closed state, the inflation pump 241 inflates the air bag 25 to increase the inflation amount of the air bag 25, and correspondingly, when the inflation/deflation control module 11 controls the inflation pump 241 to be in a non-operating state and the electromagnetic valve 242 to be in an open state, the air in the air bag 25 is discharged through the electromagnetic valve 242 to reduce the inflation amount of the air bag 25, so that the inflation/deflation control module 11 controls the operating state of the inflation/deflation assembly 24 to change the inflation amounts of the air bags 25 and adjust the angle of the speaker assembly 23 in the assembly groove 221 of the headrest 22, so that the two speaker assemblies 23 form a better listening position at the head of a user for the user to hear a good sound effect.
