Bluetooth Speaker Quality Control, Inspection, Manufacturer Audit & Lab Testing Services

Bluetooth speakers offer an easy way to bring quality audio to any space, and are perfect for both personal and shared listening environments. The small and lightweight design of these speakers makes them ideal for use on the go or in situations where traditional wired speakers are not practical. It’s now possible to make phone calls, listen to podcasts, and so much more wirelessly.

Most Bluetooth speakers are manufactured by factories in China, India and Asia. They are then exported worldwide then sold by importers, retailers, traders in other markets such as Europe, America, Middle East, Africa etc…

Those products are packed with technologies and their quality relates to many factors such as components and material quality, mechanical parts quality, assembly workmanship, and obviously design. Even the glue type used to mate all the parts may have influence on sound quality, and product durability.

Bluetooth Speaker Product Inspection Service for Components

Bluetooth speaker usually integrates the following: 

• Rechargeable lithium batteries
• PCBAs including amplifier, DSP chips, Bluetooth chips, leds
• Microphone
• Buttons key switch
• Auxiliary audio input and output connectors
• Mechanical parts such as plastic parts for housing
• They also sometimes include rubber parts, screws and glue.
• Loud speakers

The sound quality of a Bluetooth speaker can be greatly influenced by the quality of its components, and therefore by the bill of materials.

If you are manufacturing Bluetooth speakers in China or in Asia, then performing quality control and inspection on those sub parts are then highly recommended.

Our quality inspection company  gets quality inspectors nearby your factory to help you to ensure the right components and materials are used to manufacture your Bluetooth speakers.

Bluetooth Speaker Product Quality Check Service for Manufacturing

Depending on the design, Bluetooth speakers manufacturing may involve a lot of different process steps which each of them expose quality risks.

Among them, the following processes are frequently used:

For electronic parts:

• PCB manufacturing (a sensible part which can make or break your product). PCB quality and performance control are frequently neglected because most of the time people don’t know how to properly inspect PCBs. Yet, this part interconnects components together and can quickly become a weak point of the product when those interconnection break
• PCB components assembly involving reflow soldering, hand soldering, wave soldering.
• Lithium batteries assembling involving die cutting for electrode, electrolyte filling, bag sealing

For mechanical parts:

• Plastic injection molding for housing parts
• Aluminum CNC machining for housing parts
• Stamping, coating, painting for aluminum sound grill
• Rubber molding for dampers and keypad
• Steel CNC Machining for screws

As explained, the bill of materials for a product encompasses various components that undergo different manufacturing processes, with each process carrying its own set of risks and potential quality defects.With our quality inspection services (First Article Inspection Service), our Production Monitoring Service, and our Factory Audit Service we have the capability to support you in anticipating and controlling all of those risks, to reduce their impacts, to patch up potential quality problems and to keep under control the production of your Bluetooth speakers in China, in Asia, even worldwide allowing you to make your mass production of Bluetooth speakers successful.

Once all the parts and sub-parts have been manufactured by sub-suppliers, the assembler (the factory which you buy the finished product from) will usually performs the following process:

• Receiving parts from its own sub-manufacturer
• Inspecting the parts via an incoming quality control process (or not)
• Assembling the parts together properly (or not)
• Testing the Bluetooth speaker features with a test bench (or sometimes a human test bench)
• Perform a final quality control (or not if they are in rush to ship)
• Pack the product

Once again, each process brings its whole lot of potential quality risks (especially when they are processed by humans).

Our quality inspection agency can help you to evaluate and control those risks by implementing some quality control check points (First Article Inspection, During Production, Inspection, Pre-Shipment Inspection) along the production line or setting up a quality inspector monitoring your production during the different manufacturing phases.

• Bluetooth connectivity issues (automatic disconnecting, not connecting at all)
• Battery malfunction or battery short life
• Microphone not functioning
• Control panel or buttons keys breaking downs after a few hours of usage
• Housing blemishing
• Internal part breaking
• Parts (such as rubber one) disassembling

Bluetooth Speaker Lab Testing Service, what do we check

Bluetooth speaker compliance and reliability are usually not very well integrated by importers who usually neglect either one or the other.

Compliance is necessary for importing goods to your own market so quite often this testing is usually handled because it is a must. Regarding durability and reliability, this is another story. How to establish Bluetooth speaker quality, durability and reliability?

To ensure that Bluetooth speakers meet the desired specifications, we have capability to perform a series of product lab testing as follow:

Compliance testing:

• RoHS testing
• CE testing and certification
• FCC testing and certification
• CCC Certification
• KC Testing and Certification
• BIS Testing and Certification
• NCC Testing and Certification

Performance testing:

• Endurance testing (battery, components, speaker, housing)
• Audio performance testing
• Operating distance
• Frequency accuracy
• Distortion
• Latency
• Water resistance
