Embodiment 1

[0052] Such as Figure 3A-3G As shown, the smart phone 1 of this embodiment is a 3G / 4G / 5G mobile phone used in the prior art, which has a strong sense of technology, fast technological progress, fashion, and increasingly powerful functions. The power amplifier 2 is an audio power amplifier, which is designed and manufactured based on a power amplifier integrated circuit. First design the schematic diagram, then carry out the PCB layout design, and finally use SMT (surface mount) to complete the welding of the PCB board. The power amplifier 2 can use a class A / B power amplifier, or a class D digital power amplifier. The Class D digital power amplifier used in this embodiment specifically uses one piece of TPA3116 and two pieces of TPA3110 from TI Company of the United States. The power amplifier 2 of this embodiment is arranged in the cabinet of the car door subwoofer 4 .

[0053] The cabinet of the car door subwoofer 4 can be a single-cavity airtight cabinet, or can be made...

Embodiment 2

[0059] Such as 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...

Embodiment 3

[0062] Such as Figures 5A-5C As shown, the difference between the present embodiment and the second embodiment is that the connection between the smart phone 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 an automobile sound system, in particular to an automobile sound system based on a smart phone. The automobile sound system comprises the smart phone, a power amplifier, a sound channel loudspeaker and an automobile door subwoofer, wherein the smart phone is arranged in a vehicle, the power amplifier can be arranged in the vehicle door subwoofer or an independent power amplifier box or on a sound channel loudspeaker, and the smart phone is connected with the power amplifier in a wireless connection mode through Bluetooth and the like or a wired connection mode throughusing a copper cable and the like ; and 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 automobile sound system, a cumbersome car infotainment system is completely canceled, the cost is greatly reduced, the tone quality is greatly improved, and the sound system is more fashionable, more scientific, simpler and more practical.

Description

technical field [0001] The invention relates to a car audio system, in particular to a car audio system based on a smart phone. Background technique [0002] With the advancement of science and technology, car networking and car electronics technology are changing with each passing day. Now every car is equipped with a car audio system based on the car machine. People have higher and higher requirements for car audio systems. Not only must fashion, but also It must have a strong sense of modern technology, be convenient and easy to use, and be low in 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...
