The sound transmission holes 2 opposite to the positions of the horn 7 are directly processed on the real wood veneer, and the sound of the horn 7 mounted on the inner side of the real wood veneer is dispersed outward, which avoids the installation of a horn cover on the real wood veneer, improves the overall aesthetic appearance of the real wood veneer, and improves the production efficiency of the real wood veneer and reduces the production cost.

[0032] The sound transmission holes 2 include circular sound transmission holes 21 and long strip sound transmission holes 22. The circular sound transmission holes 21 are distributed in a circular array with the center of the horn 7 as the center and completely cover the sound emitting port surface of the horn 7. The long strip sound transmission holes 22 are uniformly and evenly distributed in a radial outward emission shape outside the circular space formed by the array of the circular sound transmission holes 21. The diameter of the circular sound transmission hole 21 located at the center position of the horn 7 is smaller than the diameter of the circular sound transmission hole 21 located at the middle ring position of the horn 7. The circular sound transmission holes 21 located at the outer ring position of the horn 7 are uniformly and evenly distributed with different diameters. The lengths of the long strip sound transmission holes 22 are different, and the long strip sound transmission holes 22 are arranged in long and short intervals. The sound transmission holes 2 in multiple forms are arranged to form an aesthetic pattern, which further improves the aesthetic appearance of the real wood veneer. The sound is more soft and three-dimensional by arranging and dispersing the sound through the sound transmission holes 2 with different sizes and shapes, which is beneficial to improve the overall sound quality.

[0033] The sound transmission holes 2 include penetrating holes and half-transmission grooves with a depth of half the thickness of the real wood veneer. The sound transmission holes 2 are arranged in an interlaced manner by the penetrating holes and the half-transmission grooves, so that the sound is more three-dimensional and beneficial to improve the sound quality.

[0034] The inner side of the real wood veneer is further provided with a sliding touch sensor 3 located at the side of the position of the horn 7. The surface of the real wood veneer is provided with a sliding touch mark 4 opposite to the sliding touch sensor 3. The sliding touch sensor 3 can sense the sliding action at the position of the sliding touch mark 4 on the surface of the real wood veneer. The sliding touch sensor 3 is electrically connected and communicated with the volume switch of the horn 7. The volume can be easily adjusted by sliding on the real wood veneer, which makes the volume adjustment more convenient, and avoids the installation of a volume adjustment knob on the surface of the real wood veneer, so that the surface of the real wood veneer is more aesthetic.

[0035] The real wood panel includes a real wood layer and a base layer, the real wood layer is fixedly combined on the front surface of the base layer, and a mounting mechanism is formed on the back surface of the base layer for mounting to the inner side of the vehicle. The base layer can be integrally formed by injection molding, and the real wood panel is attached to the surface of the base layer. The base layer supports the real wood layer to prevent the real wood layer from being damaged by external forces. The mounting mechanism is easily made on the base layer, and the real wood panel is easily mounted to the inner side wall of the vehicle body.

[0036] The back surface of the base layer is provided with a plurality of protruding columns 5, which can be closely inserted into the positioning holes 6 of each ear piece on the horn 7 shell one by one. The protruding columns 5 on the base layer and the positioning holes 6 on the horn 7 shell can be inserted to achieve stable positioning of the horn 7 in the radial direction. The horn 7 can be fixed by tight fitting between the protruding columns 5 and the horn 7 shell. Threaded holes can be provided on the protruding columns 5 to mount the horn 7 on the back surface of the base layer by screws. The above structure improves the stability of the horn 7 installation.

[0037] The base layer is formed with a touch light transmission part opposite to the sliding touch mark 4 on the surface of the real wood layer. The base layer is also provided with an atmosphere light transmission part 10. The touch back light plate 8 and the atmosphere back light plate 9 are fixedly installed on the back surface of the base layer.

The touch back light plate 8 and the atmosphere back light plate 9 are electrically connected to the circuit board for communication. The circuit board controls the switching of the touch back light plate 8 and the atmosphere back light plate 9. The above structure makes the edge of the sliding touch mark 4 on the surface of the real wood layer emit light at night, which is convenient for adjusting the volume of the horn 7 at night. The atmosphere light effect is formed on the real wood panel through the atmosphere light transmission part 10 and the atmosphere back light plate 9, making the real wood panel more beautiful at night. The touch light transmission part and the atmosphere light transmission part of the base layer can be formed by double injection molding, i.e. double injection molding of non-light transmission material and light transmission material. The light transmission part is formed by light transmission material for light transmission. The main body of the base layer can also be made of light transmission material, and a non-light transmission film is covered on the main body of the base layer.
