[0003] Speakers, commonly known as speakers, are an indispensable and important device in a sound system. All music is produced through "speakers" for people to listen to and enjoy. As the only device that converts electrical energy into "sound energy", the quality and characteristics of the speaker play a decisive role in the sound quality of the entire sound system.

[0004] The importance of car speakers in car audio systems is more prominent. In order to show excellent sound quality and positioning, the number of speakers and their layout are very important conditions. In the field of car audio, people have been pursuing such an effect: sitting in a car is like sitting in front of a stage, all sounds are emitted from the front windshield, and closing your eyes is like feeling at a concert, and the sound of each instrument can achieve the best playback effect.

[0025] The following will further describe the automobile speaker structure with a universal adjustment mechanism of the present invention in combination with specific embodiments, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the technical solution of the present invention.

[0026] Example 1

[0027] like Figure 1-4As shown, the automobile speaker structure with a universal adjustment mechanism of this embodiment includes a first mounting bracket 10, a second mounting bracket 40, a first motor 20, a second motor 60, a pulley 30, a buffer structure 50, a speaker 70 and an outer panel 80. The first motor 20 is arranged in the first mounting bracket 10, and the first rotating shaft 21 of the first motor 20 is connected with the second mounting bracket 40 and can drive the second mounting bracket 40 to rotate axially with the first rotating shaft 21 as the axis. A plurality of pulleys 30 are arranged between the second mounting bracket 40 and the first mounting bracket 10. When the first rotating shaft 21 drives the second mounting bracket 40 to rotate, the pulley 30 can roll on the first mounting bracket 10, thereby ensuring that the rotation process is carried out smoothly. The speaker 70 includes a speaker body 71 and a front cover 72. The rear end of the speaker body 71 has a column structure 73, and the side wall of the speaker body 71 is provided with a second rotating shaft 75 that passes through the side wall. A buffer structure 50 is provided between the second mounting bracket 40 and the column structure 73. The buffer structure 50 is fixed on the second mounting bracket 40. The provision of the buffer structure can reduce abnormal noise that may be generated during the rotation process and ensure a smooth rotation process. The second motor 60 is fixed on the second mounting bracket 40, and the second rotating shaft 75 is assembled on the upper and lower ends of the second mounting bracket 40 and cooperates with the second motor 60. The second motor 60 can drive the second rotating shaft 75 to rotate and then drive the speaker 70 to swing. The second rotating shaft 75 is perpendicular to the first rotating shaft 21. The outer panel 80 cooperates with the front cover 72 of the speaker 70. The car speaker structure of this embodiment can be fixedly connected to the body sheet metal through the mounting hole on the first mounting bracket 40.

[0028] Specifically, the first mounting bracket 10 includes a mounting panel 11 and a housing 12 having a cavity. An opening is provided in the middle of the mounting panel 11, and the opening is communicated with the cavity. The first motor 20 is provided in the cavity of the housing 12, and the first motor 20 can be fixed to the housing 12 by screwing. The surface of the mounting panel 11 on the side opposite to the second mounting bracket 40 is a smooth surface, and a plurality of mounting holes are provided on the periphery of the mounting panel 11. The first mounting bracket 10 can be an integrally formed structure, such as integral casting or injection molding. The pulley 30 includes a pulley body 31 and a connecting column 32 connected to the pulley body 31, and the connecting column 32 is installed on the second mounting bracket 40. The pulley body 31 is slidably matched with the smooth surface. Lubricating oil (such as vaseline) can be applied to the working surface of the pulley body 31, so as to further reduce damping and ensure smooth rotation. The second mounting bracket 40 includes a circular base plate 41, a cylindrical shaft body 42 is disposed at the center of the inner surface of the circular base plate 41, and the first rotating shaft 21 is mounted in the cylindrical shaft body 42. Connecting arms 43 are disposed oppositely on the side walls of the circular base plate 41, and the second rotating shaft 75 is mounted in the mounting holes of the connecting arms 43 disposed oppositely. The second motor 40 is fixed on one connecting arm 43. Specifically, a motor bracket 45 is disposed on one connecting arm 43, and the second motor 40 is fixed to the motor bracket 45 by bolts. The buffer structure 50 can be designed as a buffer sponge 50, and the buffer sponge 50 can be bonded to the center of the inner surface of the circular base plate 41.

[0029] In this embodiment, the speaker body 71 and the front cover 72 are fixedly connected. At this time, the rotation of the second motor 40 can drive the front cover 72 to rotate and swing slightly. Or the speaker body 71 and the front cover 72 are rotatably matched. The rotation of the second motor 40 only drives the speaker body 71 to rotate and swing slightly, while the positions of the front cover 72 and the outer panel 80 remain relatively unchanged, that is, from the outside, when the speaker structure rotates, the driver or passenger in the car will not observe the rotation or swing of the speaker structure. This structural design can ensure that the appearance layout of the speaker structure in the car remains almost unchanged, and does not affect the layout and aesthetic effect of the speaker. The first rotating shaft 21 can drive the second mounting bracket 40 to rotate 360 ​​degrees along its axial direction, and the second rotating shaft can drive the speaker 70 to rotate and swing slightly around both sides of its axial direction. According to the structural design, the amplitude of its rotation and swing can be designed to be ±α, for example, α can be 0~20°.

[0030] For ordinary technicians in this field, the specific embodiments are only illustrative descriptions of the present invention. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
