[0031] Working principle: The diaphragm 102 and the voice coil 103, the diaphragm 102 is the key component of the speaker to produce sound, made of lightweight, high-strength materials such as polyester film, carbon fiber, etc. The polyester film diaphragm 102 has good flexibility and responsiveness, and the carbon fiber diaphragm 102 is more rigid, which can provide better sound quality restoration. The voice coil 103 is tightly wound on the skeleton behind the diaphragm 102. When current passes through, according to the principle of electromagnetic induction, the voice coil 103 moves in the magnetic field and drives the diaphragm 102 to vibrate and produce sound. The voice coil 103 generally uses copper enameled wire, and its diameter and number of turns are determined according to the power and performance requirements of the speaker.

[0032] Magnet 105 and magnetic circuit system, the magnet 105 provides a magnetic field for the voice coil 103, and the common magnet 105 material is neodymium iron boron, which has high magnetic energy product and can generate a strong magnetic field. The magnetic circuit system guides and optimizes the magnetic field generated by the magnet 105, including the magnetic conductive plate 106, the pole piece 107, etc. The magnetic conductive plate 106 concentrates and guides the magnetic force lines of the magnet 105 to the surrounding of the voice coil 103, and the pole piece 107 further adjusts the magnetic field distribution to ensure that the voice coil 103 moves in a uniform and strong magnetic field, thereby improving the sound production efficiency and sound quality of the speaker.

[0033] Speaker enclosure 104, material and shape, the enclosure 104 is made of plastic or metal. The plastic enclosure 104 has low cost and good formability, and can be made into various complex shapes; the metal enclosure 104 has high strength and good heat dissipation, which can provide better protection and acoustic performance. The shape of the enclosure 104 is circular, and there are also some special designs to adapt to different installation positions and aesthetic needs of vehicles. The size of the enclosure 104 is determined according to the power and frequency response range of the speaker, for example, the diameter of the common car speaker is between 10-18 centimeters.

[0034] Acoustic design and internal damping material, the enclosure 104 has certain acoustic design, for example, through reasonable space layout and reflection structure, the sound propagation and diffusion are optimized. Some speaker enclosures 104 are also filled with damping materials such as acoustic cotton to absorb and attenuate the reflected sound inside the speaker, reduce the turbidity and distortion of the sound, and make the sound more pure and clear.

[0035] Rotary shaft 201 and bracket 202, rotary shaft 201 design and material, the rotary shaft 201 is the key component to realize the angle adjustment of the speaker, generally located at the bottom or side of the speaker enclosure 104. The rotary shaft 201 is made of metal such as stainless steel, and its diameter is between 5-10 millimeters according to the size and weight of the speaker. The surface of the rotary shaft 201 is finely processed to ensure smooth rotation, and its precision requirements are high, with axial runout and radial runout generally controlled within ±0.1-±0.2 millimeters.

[0036] The structure and fixing method of the support 202, which is used to support the speaker and connect with the mounting position of the vehicle, can be a metal support 202 or a plastic support 202. The metal support 202 has high strength and is suitable for mounting heavy speakers; the plastic support 202 is light in quality, low in cost, and convenient to process and install. The support 202 is connected with the speaker through the rotating shaft 201, and the shaft sleeve or bearing is usually used to make the speaker rotate flexibly around the rotating shaft 201. The fixing method of the support 202 with the vehicle has various types, such as bolt 109 fixing and buckle fixing. The bolt 109 fixing is firm and reliable, and the buckle fixing is more convenient and fast.

[0037] The angle locking device, the mechanical locking method includes bolt 109 locking, buckle locking, etc. The bolt 109 locking is to set the bolt 109 on the rotating shaft 201 or the support 202, and when the angle of the speaker is adjusted, the bolt 109 is tightened to fix the relative position between the speaker and the support 202. The buckle locking is to use the elastic buckle structure to tighten the buckle after the angle is adjusted to prevent the speaker from rotating. This mechanical locking method is simple and effective, and has low cost.

[0038] The general mounting interface, the standard mounting hole 108 and the size, in order to facilitate the installation on different vehicles, the speaker is designed with a general mounting interface, such as a standard mounting hole 108. The position and size of these mounting holes 108 meet the common vehicle-mounted audio installation specifications, for example, the diameter of the mounting hole 108 can be between 6-8 mm, and the hole spacing is between 8-16 cm according to the size and shape of the speaker, which is convenient for installation with standard bolts 109.

[0039] The way to adapt to different vehicle models, by providing various installation accessories, such as bolts 109 of different lengths, gaskets of different shapes, etc., so that the speaker can adapt to the installation environment of various vehicle models. For example, for vehicles with deep installation positions, longer bolts 109 are provided; for uneven installation surfaces, adjustable gaskets are provided to ensure that the speaker can be firmly and evenly installed on the vehicle.

[0040] The electromagnetic induction drives the diaphragm 102 to produce sound. When the audio current passes through the voice coil 103 of the speaker unit, the voice coil 103 will be subjected to a force related to the direction of the current and the direction of the magnetic field due to the electromagnetic induction principle \(F=BIL\) where \(F\) is the electromagnetic force on the voice coil 103, \(B\) is the magnetic field strength, \(I\) is the current intensity, and \(L\) is the effective length of the voice coil 103 wire. This force makes the voice coil 103 move back and forth in the magnetic field, and the voice coil 103 is closely connected with the diaphragm 102, thereby driving the diaphragm 102 to vibrate synchronously. The vibration of the diaphragm 102 causes the density change of the surrounding air molecules, producing sound waves and realizing the propagation of sound.

[0041] The magnetic circuit system optimizes the magnetic field effect, and the magnet 105 and the magnetic circuit system jointly optimize the magnetic field. The magnetic force lines generated by the magnet 105 are concentrated and guided to the surrounding of the voice coil 103 through the magnetic conductive plate 106, so that the magnetic field intensity distribution of the area where the voice coil 103 is located is more uniform. The pole piece 107 further adjusts the direction of the magnetic field to ensure that the voice coil 103 receives stable and strong magnetic field force in the direction perpendicular to the diaphragm 102. This optimized magnetic field structure can improve the motion efficiency of the voice coil 103 and make the vibration of the diaphragm 102 more linear, so as to more accurately restore the frequency and amplitude of the sound signal and improve the sound quality.

[0042] The rotating shaft 201 and the support 202 realize angle adjustment, and the rotating motion principle is that the rotating shaft 201 is located at the bottom or side of the loudspeaker shell 104 and is connected with the support 202 through a shaft sleeve or a bearing. When it is necessary to adjust the angle of the loudspeaker, an external force is applied to make the loudspeaker rotate around the rotating shaft 201. Taking the shaft sleeve connection as an example, there is a certain gap between the inside of the shaft sleeve and the rotating shaft 201, and the gap allows the rotating shaft 201 to rotate flexibly in the shaft sleeve. The bearing connection is more precise, and the rolling contact between the rolling balls or rolling needles and the inner and outer rings reduces the friction force, so that the rotation is smoother. During the rotation process, the loudspeaker can change its sound emitting direction within a certain range to meet the listening needs of passengers at different positions in the vehicle.

[0043] The support 202 supports and connects the principle, and the support 202 serves as a support structure to fix the loudspeaker on the vehicle and bears the weight of the loudspeaker. The connection mode of the support 202 and the rotating shaft 201 ensures that the loudspeaker can stably rotate around the shaft. At the same time, the fixing mode of the support 202 and the vehicle such as bolt 109 fixing or buckle fixing ensures the stability of the entire device during the driving process of the vehicle. The bolt 109 fixing fixes the support 202 on the vehicle by screwing the bolt 109 into the screw hole of the mounting position of the vehicle, and uses the friction force and pre-tightening force of the threads of the bolt 109 to firmly fix the support 202 on the vehicle; the buckle fixing uses the elastic deformation of the buckle to make the buckle enter the clamping groove 203 of the mounting position of the vehicle, and when the buckle returns to its original shape, a clamping force is generated to fix the support 202 on the vehicle.

[0044] Finally, it should be noted that the above content is only used to illustrate the technical scheme of the present application, and is not a limitation on the protection scope of the present application. Simple modifications or equivalent replacements of the technical scheme of the present application by ordinary skilled in the art do not deviate from the essence and scope of the technical scheme of the present application.
