GM motor coaxial/ low pitch sounder loudspeaker device and manufacturing method thereof

Abstract

The invention discloses a GM motor coaxial/ low pitch sounder loudspeaker device. A ring-shaped cushion ring and the loudspeaker are arranged in an upper boss of a loudspeaker support and are fixed at the inner side of the support through pivots. An installation screw hole is formed at the edge of the outer edge of the support and is corresponding to a fixing hole of a vehicle body metal sheet part. The GM motor coaxial/ low pitch sounder loudspeaker device has the advantages that the installation screw hole identical with the vehicle body metal sheet part is formed in the loudspeaker support, no other holes are needed to be formed again, installation is easy, the support is fixed through anti-loose bolts, the problem that the loudspeaker is damaged because of dislocation of a tapping screw connecting method after a long using time is avoided, structure of a vehicle is prevented from being damaged, reliability is high, installation working hours are reduced, installation is convenient and rapid, electric safety is guaranteed, and sound quality of the vehicle sounder is improved.

Description

technical field [0001] The invention relates to a loudspeaker assembly, in particular to a coaxial / subwoofer loudspeaker device for GM vehicles. Background technique [0002] At present, the coaxial / subwoofer speaker is installed on the GM general car, and the hole is re-drilled on the original car, and a non-standard wooden bracket is made by hand or a commercially available general-purpose plastic bracket is used to install the coaxial / woofer speaker, and the original car is demolished. The electrical circuit is connected to the signal line, which has low efficiency and poor reliability, forming a potential safety hazard. [0003] 1) Because the installation position, size, and shape of the handmade wooden bracket do not match the various models of GM General Motors, it is necessary to open holes in the original car to install the coaxial / woofer speaker, which will increase the man-hour and cost, and It is easy to cause sheet metal corrosion. If the debris left after the ...

AI Technical Summary

Problems solved by technology

[0002] At present, the coaxial / subwoofer speaker is installed on the GM general car, and the hole is re-drilled on the original car, and a non-standard wooden bracket is made by hand or a commercially available general-purpose plastic bracket is used to install the coaxial / woofer speaker, and the original car is demolished. Electrical lines are used to connect signal lines, which has low efficiency and poor reliability, which poses a safety hazard

[0003] 1) Because the installation position, size, and shape of the handmade wooden bracket do not match the various models of GM General Motors, it is necessary to open holes in the original car to install the coaxial / woofer speaker, which will increase the man-hour and cost, and It is easy to cause sheet metal corrosion. If the debris left after the hole is not cleaned up, it will be adsorbed on the installed coaxial / woofer speaker, causing noise and damage to the speaker;

[0004] 2) Use wooden materials to make car speaker brackets, which are easy to absorb moisture and increase the weight of the car, thereby increasing fuel consumption, and are not easy to install on the car, and the speakers are easy to fall off after a period of use;

[0005] 3) Use a commercially available general-purpose plastic bracket, which is not compatible with GM general vehicles. It also needs to drill holes in the body sheet metal like a wooden bracket, which is likely to cause sheet metal corrosion, and the debris left after the hole is not cleaned. Will stick to installed coaxial / subwoofer speakers, creating noise and causing speaker damage;

[0006] 4) Manual wooden brackets and commercially available general-purpose plastic brackets are not resistant to high and low temperature, impact resistance, and low mechanical strength, which cannot meet the complex installation environment of car speakers, and are easy to resonate with speakers, affecting sound quality
