Logitech UE Mobile Boombox Bluetooth Mobile Speaker Teardown

24 April 2013
The following is an overview of a teardown analysis conducted by IHS Technology Teardown Services.

IHS Insight Perspective

$99 wireless speaker bar from Logitech. This fits in the middle of a range of wireless speaker options ranging from $50 to $350 in the wireless speaker bar market. With its dual speakers, CODEC, and low retail price ($100), probably the lowest manufacturer's profit margin in its class, and the most "bang for the buck for the consumer.

Volume Estimations

150,000 Annual Production Volume
3 Total Years

For the purposes of this teardown analysis, we have assumed an Annual Production Volume of 150000 units and a Product Lifetime Volume of 3 year(s).

Teardown volume and production assumptions are primarily used for our cost analysis in terms of amortized NRE and tooling costs, especially for custom components specific to the model being analyzed (mechanical components especially). Unless assumed volumes are different by an order of magnitude, minor changes in volume (say 1 million vs. 2) rarely have a large net effect on our final analysis because of this.

Cost Notes

Component pricing reflects, in most cases, the volumes provided. Areas where specific production volumes may have limited effect include smaller passive components.

Logitech UE Mobile Boombox Bluetooth Mobile Speaker Cost AnalysisLogitech UE Mobile Boombox Bluetooth Mobile Speaker Cost Analysis

Not Included in Analysis

The total materials and manufacturing costs reported in this analysis reflect ONLY the direct materials cost (from component vendors and assorted EMS providers), AND manufacturing with basic test. Not included in this analysis are costs above and beyond the material manufacture of the core device itself - cost of intellectual property, royalties and licensing fees (those not already included into the per component price), software, software loading and test, shipping, logistics marketing and other channel costs including not only EMS provider and the OEM's margin, but that of other resellers. Our cost analysis is meant to focus on those costs incurred in the manufacture of the core device and exceptionally in some circumstances the packaging and literature as well.

We do provide an Excel tab 'Overall Costs' where a user can enter their known pre and post production costs to build a per unit cost reflective of theirs actual expenditures.

Country of Origin

For the purposes of this analysis, we are assuming the following country(ies) of origin for each level of assembly, based on a combination of 'Made In' markings, and/or assumptions based on our knowledge of such equipment.

Box Contents - China
Main PCB - China
Misc Interface PCB Assemblies - China
Other - Enclosures / Final Assembly - China

Country of origin assumptions relate directly to the associated cost of manufacturing, where calculated by iSuppli. In the cases of 'finished' sub-assemblies (such as NFC modules), we do not calculate internal manufacturing costs, but rather assess the market price of the finished product in which case country of origin assumptions may or may not have a direct effect on pricing.

Labor rates are applied directly only to hand inserted components and systems in our bill of materials, and although regional assumptions do, these new rates do not have a direct effect on our modeled calculations of placement costs for automated SMD assembly lines. ""Auto" inserted components (such as SMT components) placement costs are calculated by an iSuppli algorithm which allocates a cost per component based on the size and pincount of the device. This calculation is affected by country or region of origin as well.

Design Complexity

Component counts by assembly and the number of assembly are indicators of design complexity and efficiency.

Component Qty: 52 - Other - Enclosures / Final Assembly
Component Qty: 223 - Main PCB
Component Qty: 16 - Box Contents
Component Qty: 17 - Misc Interface PCB Assemblies
Component Qty: 308 - Grand Total

The average component count of the 5 dual-driver designs we looked at was roughly 415 components. At 308 the Logitech UE is ~25% lower than average in terms of component and resulting build complexity.

Design Notes

Electronics - the main design 'choices' here in terms of electronic (IC) content come down to the CSR BlueCore 5 chip, and the Wolfson audio codec. Other IC content includes audio amplifier Ics, and power management - but these are relatively inexpensive choices and dont even show up on the 'above $1' list below.
