  • Failure mode Poor speaker quality, lack of electronic filtering and case vibrations can lead to poor sound quality.
  • Durability feature Rigid speaker casings and anti vibration mounts, combined with bandpass filters, can help to prevent poor sound quality.

Key facts

  • People expect TVs to last 5 to 10 years.
  • Barriers to buying own-brand products is the perception that they are less reliable.

Specification for improved performance

The specification below provides the recommended improvements needed to improve product durability. They are ranked from bronze to gold based on the effectiveness of the change in improving durability, with bronze being the minimum and gold being the maximum.

Better design and manufacture

  • Ensure rigid speaker casing  with strong materials such as PC- ABS.
  • Anti-vibration mounts, e.g. speaker case on rubber spacers/grommets
  • Anti-vibration pads to prevent contact with the case or other TV parts  
  • High-pass / low-pass filters to limit the frequencies fed to the speaker to ensure it is only receiving frequencies within its bandpass
  • Key components to be surface mounted on sound PCB
  • Soldered connections to be used where this will not inhibit replacement of key components
  • Easily accessible / replaceable sound PCBs without need for special tools
  • Parts to be available in the UK at a reasonable price for at least 5 years after the last unit manufactured. 

Sound PCB to IPC610E / IPC-J-STD-001; QC testing

  • Sound PCB to comply with IPC610E and IPC-J-STD-001
  • Quality control testing to be undertaken and documented *
* 1% of each TV production batch to be tested for good sound quality without vibration or distortion at 50% of maximum volume. Test method used to be declared. AES2-2012 and IEC268-5 may be helpful as standards covering measuring / specifying the performance of loudspeakers.

Testing to demonstrate performance

Ask for clear evidence of meeting the requirements listed above, e.g.

  • technical specifications, drawings, photographs
  • test data (ideally from an independent test house), quality control data    


Cost implications

Improved reliability of components can reduce early returns and improve brand reputation which, in turn, can lower business costs and increase long-term sales.

To calculate overall cost savings for your business, use the WRAP cost/benefit analysis tool (currently in draft form and available on request).



Specifying better materials in speaker casing

Small changes to mouldings and material specification should only add a few pence or tens of pence,  assuming tooling change is minimal.

Low cost

Rigid mounting on anti vibration mounts to be used (e.g. rubber grommets)

The rubber mounts themselves would be very low cost (pence per unit). The significant cost could be in allowing the fitting in a revised moulding  with associated tooling costs.

Surface mount technology

The use of surface mounted components could add a significant cost depending on the volumes made and production techniques available in the factory of choice.  

Speaker/PCB  testing and inspection 

Any testing and inspection will add a small amount of cost in terms of rig time and labour costs.

High cost
