Car audio system includes mobile audio, car audio, 12-volt audio and other terms used to describe sound systems fitted to an automobile or other vehicle. The primary use of such equipment is usually entertainment, but can also include communications equipment, public address, and other similar applications. Common components found in most basic modern vehicles are the stereo sound head unit, AM/FM transmitter, CD player, a pair of speakers mounted in the interior panels, and an auxiliary input jack or USB jack for external playback devices or smart phones. The following figure named "Car stereo system circuit diagram " demonstrates the typically installed equipment within the car stereo system. Nowadays, people pay more attention on the ever-evolving automotive infotainment applications of the vehicle audio systems to enjoy a more comfortable time when they are driving on the way. Thus, more and more companies intended to develop the application in video processing, audio processing and telecommunication technologies to cater the consumers’ fond. Furthermore, vehicle audio manufactures enhance the value of their products by aiming for high sound quality.
Automobile seat headrest audio
This invention provides a car seat headrest speaker, including a microcontroller, a digital signal processor, a power amplifier chip, and two pins. The power amplifier chip is connected to a speaker and the digital signal processor; the digital signal processor is connected to the microcontroller; and the microcontroller has a Bluetooth transceiver. The speaker is detachably connected to the car seat headrest. The two pins connect to the vehicle's infotainment system, through which the microcontroller receives CAN protocol signals and controls the Bluetooth transceiver to enter TWS pairing mode based on the CAN protocol signals. This invention achieves multi-scenario speaker use through a detachable design and utilizes physical pins to transmit CAN bus signals to activate TWS pairing, solving the problems of existing car audio systems being non-detachable and limited in use scenarios. While ensuring driving safety, it enhances the auditory immersion and interactive experience for drivers and passengers.

Car audio
This utility model discloses a car audio system, which includes a speaker assembly and a decorative opening and closing mechanism. The speaker assembly includes a support base and a speaker. The support base includes a housing, and the speaker is disposed inside the housing. The decorative opening and closing mechanism includes a trim assembly and an opening and closing drive assembly. The trim assembly includes multiple protective trim pieces, which are circumferentially arranged around the housing and rotatably mounted on the housing. The opening and closing drive assembly is driven by the multiple protective trim pieces and drives them to rotate between an open and closed state. When rotated to the closed state, the multiple protective trim pieces can house the housing within them. The protective trim pieces serve both decorative and protective functions, effectively preventing the housing from being directly damaged by external impacts, ensuring the sound quality and aesthetics of the car audio system, and preventing dust and moisture from entering the housing, thus extending the lifespan of the car audio system.

Inverted magnetic circuit ultra-thin structure automobile horn
An inverted magnetic circuit ultra-thin car horn includes a frame, a spider, a diaphragm, a voice coil, a suspension system, and a magnetic circuit system. The magnetic circuit system includes a main magnet, a secondary magnet, a U-shaped iron, a washer, and a bullet-shaped head. The magnetic circuit system is inverted and installed above the suspension system, and is fixed by screws. The frame is made of die-cast aluminum and supports the suspension system and the magnetic circuit system. The suspension system includes a spider, a diaphragm, and a voice coil, and the voice coil is spaced with the magnetic circuit system to drive sound production. The installation depth of the horn is less than 43mm. This utility model has a novel structure and ingenious design. By installing the magnetic circuit system above the suspension system with an inverted magnetic circuit structure, it breaks through the traditional height limitation of "suspension system + magnetic circuit system" for horns, meeting the needs of scenarios with strict requirements for installation depth, such as ceiling speakers, wall speakers, and car audio systems.

A method for implementing automobile sound effects based on a real performance venue model
This invention provides a method for implementing car audio effects based on a real performance venue model. The method includes: S1: placing a sound source to be tested in the target performance venue, and setting up at least two sets of performance venue test points with the sound source to be tested as the origin, collecting the performance venue impulse response at each performance venue test point, and forming an original acoustic signal; S2: processing the original acoustic signal to obtain a standardized acoustic signal; S3: controlling the car audio system in the car cabin to play the test sound, setting up at least two sets of cabin test points in the car cabin, and collecting and obtaining the cabin impulse response; S4: extracting the performance venue impulse response and the cabin impulse response, calculating and obtaining the target impulse response; S5: calculating the target audio signal y(t) by performing a convolution operation between the standardized acoustic signal and the target impulse response; S6: adjusting the sound effect parameters of the target audio signal and playing it through the car audio system in the car cabin.

ActiveCN224290049UReduce development costsreduce occupancyElectrical transducersInterior spaceIn vehicle
This application provides a vehicle audio system and a vehicle. The vehicle audio system includes a first speaker, which comprises a housing and a diaphragm. The diaphragm is disposed within the housing, and a rear acoustic cavity is formed behind the diaphragm. The housing has a guide hole communicating with the rear acoustic cavity. The first speaker is mounted inside the vehicle body, with the front of the diaphragm facing the passenger compartment, and the guide hole communicating with an external speaker outlet. When the first speaker operates, the diaphragm generates forward and backward sound waves. The forward sound waves can be conducted to the passenger compartment inside the vehicle to play audio into the vehicle, while the backward sound waves can be conducted through the rear acoustic cavity and the guide hole to the external speaker outlet to play audio outside the vehicle. The first speaker not only supports audio playback inside the vehicle but also supports audio playback outside the vehicle. This eliminates the need for additional hardware such as multiple dedicated external speakers in the vehicle to achieve external playback functionality, reducing the occupation of interior space and lowering vehicle development costs.
