The high and low temperature resistance of the audio cable can adapt to the internal cold and hot circulation environment of air conditioning.
The flexible cabling capability of audio cables simplifies the installation process.
It connects to the display’s audio module to guarantee audio signal integrity.
The vibration resistance of the audio cable prevents the connection from loosening.
Exact Wire Gauge Matching for Optimal Sound
The wire gauge of your audio cable is crucial for not losing any acoustic power. Our 16 AWG conductors are engineered for high wattage home theater speakers to produce maximum output. For internal smart assistant microphones we offer ultra thin 32 AWG audio input cable solutions to conserve valuable circuit board space.
Specific Outer Jackets for Appliance Environments
Depending on the outer jacket material of your audio cable, its durability will vary in different temperature ranges of appliances. We extrude cost effective PVC jackets for standard 80℃ smart home environment. For extreme heat in smart air Fryers we produce silicone coated acoustic wiring types which can be safely exposed to continuous 200℃ without melting.

The thicker the gold, the longer the audio wiring lasts when carrying out continuous vibration. Static connections for a smart speaker are fine with 3 μ m plating. Thin plating can wear away quickly, however, if the appliance has a heavy motor vibration, then micro fretting occurs. Recommended upgrade to 15 micron 15 micron gold plated digital cable. This denser layer will resist base metal oxidation and have zero contact resistance.

Your audio cable does not flatten when bent over sharp appliance corners with the use of internal cotton yarn fillers. Impedance drop and signal distortion is a significant problem with flattened wires. The cotton strands hold the optical acoustic wiring in the ideal cylindrical shape during the tight internal routing. This structural support also relieves pulling stress on internal copper conductors from any damage incurred in the manufacturing process.
Ground loops happen when the audio cable rca is in the same circuit as high current devices, such as switching power supplies. This produces a verylow resonant hum. In order to resolve this, the engineer needs to physically move the audio input cable away from AC power lines, at least 50mm. In addition, using a separate ground wire at one point on the metal chassis will break the circuit and silence any speakers.
Potting compounds are liquid epoxy that are filled into the back cavity of the acoustic wiring to the aux connector shell. After the cure, this hard resin turns all the delicate soldered joints into solid resin block. It prevents vibrations from the ultrasonic motor to pass through into the acoustic stream. This tight sealing will also render the pro cables entirely waterproof in case of a mess on the inside of smart kitchens.
For long routing distances, high-frequency roll-off is caused by high internal capacitance. This results in muffled smart speaker voice feedback. This digital cable is designed with a thick foamed PE dielectric material, which greatly reduces mutual capacitance and retains high pitch voice commands.
