Description

Technical Field

[0001] The invention relates to the technical field of automobile audio, and in particular to an automobile audio system capable of preventing vibration. Background Art

[0002] Car audio is a device for receiving and playing audio to relieve the boredom of drivers and passengers during travel. The earliest car audio was AM radio, followed by AM / FM radio and tape player, and then CD player and compatible DCC and DAT digital audio. Now, car audio has reached a high standard in terms of timbre, operation and vibration resistance, and can cope with the bumps of the car on the rugged road, ensuring stable performance and perfect sound quality.

[0003] There are also some technical solutions for automobile equipment in the prior art. For example, a Chinese patent with announcement number CN215818506U discloses a highly integrated automobile audio system, including an automobile audio fixing frame, an audio housing, an audio main body fixing plate, an integrated audio main body, an audio installation device, a cleaning sliding groove, and an audio dust removal device. The utility model installs the audio main body through the audio installation device, and a shock-absorbing spring is arranged in the audio installation device. The shock-absorbing spring can offset the vibration occurring during the driving of the car, thereby ensuring the stability of the audio main body itself, thereby making the sound quality stable. An audio dust removal device is provided, and by rotating the dust removal device, the dust removal brush collects dust inside the car audio fixing frame to the dust removal port, thereby preventing dust accumulation from affecting the sound quality of the audio, and improving the user's use experience. The integrated audio body is installed on the audio body fixing plate, and the audio is integrated on the fixing plate through high integration, so that the volume of the audio is small while ensuring the output of sound quality, and reducing space occupation.

[0017] Beneficial effects of the present invention:

[0018] An expansion airbag and a rubber buckle are arranged on the periphery of the car speaker fixing frame. The rubber buckle is "U"-shaped. When the car speaker fixing frame and the integrated speaker body are installed in coordination, the expansion airbag is in a contracted state. During installation, the rubber buckle is clamped between the inner and outer sides of the hole wall of the reserved hole. The air intake of the air pressure tank is realized through the cooperation of the air intake plug and the air intake pipe. After the air pressure tank is inhaled, high-pressure gas is stored in the air pressure tank. After storing the high-pressure gas, when the expansion airbag is in a deflated state, the first electrode block contacts the second electrode block, which can realize the power-on operation of the motor and drive the rotating disk to rotate. With the cooperation of the pull rod, the movable plate is pulled. During the pulling process, the movable plate slides along the inner wall of the limit frame.

During the air intake process, the expansion airbag is inflated, and there is no gap between the rubber buckle and the reserved hole wall for installation. The filling property of the space is better, there is no vibration space, and no noise is generated, so the music quality is guaranteed. When the gas in the expansion airbag leaks or is relaxed due to the influence of the external environment, the first electrode block and the second electrode block inside the expansion airbag are in contact, so that the motor is energized, which can drive the movable plate to slide along the inner wall of the limit frame, so as to realize the air replenishment operation, and can ensure the stability of the audio installation for a long time, and reduce the maintenance process.

[0019] When the gas at the bottom of the pressure tank is gradually consumed, the piston slides upward along the inner wall of the pressure tank, driving the connecting rod to rise, thereby realizing the rise of the electrode ball. During the gradual rise, it indicates that the gas in the top of the pressure tank is replenished into the expansion airbag to ensure the stability of the installation. When the gas inside the pressure tank is consumed, the electrode ball contacts the electrode ring to power on the warning light. After the warning light is powered on, it is necessary to replenish the air in the pressure tank through the air intake pipe to ensure the stable installation of the speaker, avoid loosening of the installation position, reduce vibration space, avoid vibration operations, and provide timely feedback to ensure the safe use of the audio.
