In car audio, the role of DSP is particularly important, a sound without a DSP car audio system will never come out. You may ask why you say this? Because this has a direct relationship with the complex environment inside the car, the fixedness of the speaker placement in the car and the unadjustability of the listening position of the people will make the effect of the entire car sound not play well.
The appearance of DSP overcomes the complicated environment inside the car, so that it can play the sound quality of the sound. The unique 31-stage EQ adjustment system of DSP can adjust the gain of each channel at will. The adjustment of Q value can make the acoustic curve of the whole car. Smoother, complementing the defects on each speaker and unearthing the optimal performance of each speaker.
DSP's own delay system allows the entire sound field to be gathered and concentrated, and the positioning of the sound field is tailored. Let the sound of the whole car form a stage, the singer is in the middle, the singer is accompaniment on both sides! That feeling is really exciting and makes people self-evident. In addition to the space constraints, car audio can hear a lot of low-frequency noise, engine noise, low-frequency noise in the car, wind noise at high speed, etc., which will offset the sound of some frequency bands, and the audio equipment is not installed. Improper, the absorption of the material inside the car and other factors, the overall frequency response of the sound system is an uneven response curve.
The role of the equalizer is to correct these uneven frequency bands in order to obtain a relatively flat overall response curve.
For the interior of a car stereo, the location cannot break the limits of physical space. Because the main driver, the co-driver and the rear seat are the spatial positions of a square, the speed of the sound is different, and the high-pitched, mid-range, and bass are different from other designs. The treble may be near the A-pillar, and the midrange is at the left and right of the driver's leg, and the bass will be lower. (only for three-way frequency)
The treble will not pass the obstacle, so the treble in the car will be placed directly to the listener.
The midrange hits the obstacle and can go around, so the midrange can be placed near the seat, bypassing the obstacle and reaching the listener's ear.
The bass can be heard and shaken with obstacles, so it is placed in the trunk.
Some car owners will ask, my car is a high-definition version, the speaker is also the best in the industry, the original car has its own amplifier, but also DSP? Host-amplifier-speaker is the basic sound system, already has a car, to make This system is more detailed and more detailed, and the music is played more completely. It is necessary to add a DSP intelligent sound processor to the sound system. Music, knowing him will love it more, if you want to enjoy the beautiful melody in the driving time, indulge in the beautiful singing accompanied by mobile music; if you have a certain love for music, there is a certain sound quality If you are pursuing it, welcome to the franchise stores across the country to discuss with us.

Portable power stations, also known as battery powered inverter generators, are rechargeable units capable of dispensing power for charging devices. It is equipped with AC outlet and USB charging ports. Camping trips and power outages are best applications of these units. The global portable power station market size is set to reach USD 482 million by 2026, according to Market Research Future (MRFR). It can display 7.60% CAGR over the forecast period (2020-2026). Huge demand for alternatives to gas generators and need for units capable of running heavy applications can drive the majority of the market demand.
The market growth is attributed to rising use of smart electronic devices and huge requirement for uninterrupted power supply. Areas frequented by power outages caused by natural disasters are expected to be a lucrative market for portable power stations. Residents are shelling out for these generators for charging smartphones capable of calling emergency responders. Moreover, discounts and deals for portable power stations on ecommerce portals can drive the market volume significantly. The large opportunity for consumer electronic products owing to restrictions on movement during the pandemic can be leveraged by market players.
The long charging times and high costs of these generators can restrain market growth.
