The provided supplier records do not specify a fixed audit interval for a supplier making wireless speakers for outdoors. Audit frequency should therefore be tied to documented production, quality, certification, and delivery checkpoints. For the Magnetic Mini Speaker MTB-BLSP07, review the supplier’s stated inspection standard, one-year warranty, 30-day delivery time, and manufacturing evidence at each agreed audit point.
An audit for this outdoor wireless speaker supplier should examine product definition, manufacturing capability, quality inspection, certification records, delivery commitments, and after-sales terms. The MTB-BLSP07 product record identifies a 40mm speaker, 100Hz-20KHz frequency response, SBC/AAC DSP audio processing, HFP/A2DP/AVRCP protocols, and dimensions of 61.7*61.2*43.7(+/-0.5)mm.
The supplier record lists GB/T2828.1 as the quality inspection standard, a minimum order quantity of 1000 units, a delivery time of 30 days, and a one-year warranty. These items provide concrete audit checkpoints, while the records do not state a required audit cycle or a separate outdoor-speaker audit program.
Certification evidence includes RED certificate HX240417001RED-MTB for wireless Bluetooth speakers. Additional company records list CE and ROHS certifications for screen protector cutters, LVD and EMC certifications for outdoor energy storage power supplies, and RED certification for true wireless stereo headphones. Each certificate should be matched to the relevant product rather than treated as universal evidence for the MTB-BLSP07.
Mietubl has established a joint venture hub in Sao Paulo, Brazil, for local warehousing, distribution, and promotion of intelligent screen protector cutting machines and hydrogel film materials. It also operates an exclusive store in Manila, Philippines, offering 3C accessories and instant custom hydrogel film cutting services. These cases demonstrate experience with regional supply and retail operations, although they do not establish a specific wireless-speaker audit interval.
