Embodiment 1

[0051] like Figure 3A-3G As shown, the appearance of the tablet car machine 1 of this embodiment is like a tablet computer, and its thickness is very thin. This flat car machine 1 is provided with display screen, radio and signal processing system, and the size of the display screen can be larger or smaller according to cost and customer requirements. What this embodiment used was a 7-inch display screen, and the flat car machine 1 The thickness is 12mm; the radio and signal processing system includes the management and control of AM, FM radio and AUX, USB, Bluetooth and other audio source signals, as well as the management and control of 4G, 5G and navigation, and further completes DSP and EQ adjustment for audio signals. Audio processing to make the played audio signal more perfect and better-sounding. In this embodiment, a special chip for vehicles of NXP Company is used. The overall design appearance and schematic diagram of the whole flatbed car machine 1, then design ...

Embodiment 2

[0059] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is: the power amplifier 2 of this embodiment is arranged in an independent power amplifier box 10, and the power amplifier 2 is a PCB board with a length of 43 mm × 86 mm width × 20 mm high, and the independent power amplifier box 10 The outer dimension is a box body with a length of 50mm x a width of 92mm x a height of 30mm. This independent power amplifier box 10 can be made of plastic or metal such as iron; the present embodiment is made by mold-opening injection molding. In addition, the power amplifier 2 of this embodiment is a four-channel output, that is, the front left, right and rear left and right four-channel output, and they are respectively connected to the corresponding front left, right and rear left, right and rear left and right of the channel speakers 3 with copper cables. Right quad speaker. The front left, right and rear left and right speakers of this embodiment are al...

Embodiment 3

[0061] like Figures 5A-5C As shown, the difference between the present embodiment and the second embodiment is that the connection between the flatbed car machine 1 and the power amplifier 2 of this embodiment is a wireless connection, that is, a Bluetooth connection, and the power amplifier 2 of this embodiment is set on one of the channel speakers 3 On the basin frame and the guard plate of the loudspeaker unit, the power amplifier 2 of the present embodiment is arranged on the 6.5 ″ loudspeaker at the bottom of the front left car door. All the other are identical with embodiment two.

Abstract

The invention relates to a car audio system, in particular to a car sound system based on a tablet car infotainment system. The car sound system comprises the tablet car infotainment system, a power amplifier, a sound channel loudspeaker and a car door subwoofer, wherein a display screen, a reception and signal processing system are arranged in the tablet car infotainment system; the power amplifier can be arranged in car door subwoofer, or on the loudspeaker, or in an independent power amplifier small box; the tablet car infotainment system and the power amplifier are in wireless connection through Bluetooth and the like or in wired connection through a copper cable, an optical fiber, a coaxial cable and the like; an active woofer and a passive woofer are arranged in the car door subwoofer; and a box body of the car door subwoofer is composed of a front box body, a rear box body and a crank throat pipe. According to the car audio system, a cumbersome iron box car infotainment system is canceled for the car audio, the occupied space is reduced, the structure is simple, the cost is greatly reduced, and the fashionable science and technology feeling is stronger.

Description

technical field [0001] The invention relates to a car audio system, in particular to a car audio system based on a flat car machine. Background technique [0002] With the advancement of science and technology, car networking and car electronics technology are changing with each passing day, people have higher and higher requirements for car audio systems, which must not only be stylish, but also have a strong sense of modern technology, convenience and ease of use, and low cost. The current car audio system is an old technology that has been used for 50 years, and it is in urgent need of innovation and improvement. At present, the existing car audio technology has the following two solutions: [0003] Option 1, integrated iron box car machine + four-channel speaker type; such as figure 1 As shown, this method accounts for 80% of the current automotive OEM market. This all-in-one car machine is set in the central control part of the car instrument, with a built-in display...
