Stars
MEMS microphones for smartphones
Knowles remains a go-to name in mobile MEMS microphones with billions of MEMS mics shipped annually; predictable 12–18 month smartphone refresh cycles and OEM willingness to pay for performance sustain high ASPs. Growth in multi‑mic arrays and video‑centric capture—flagship devices commonly using 3–5 mics—keeps demand hot, so continued R&D and design‑wins are essential to retain market leadership.
Acoustic modules for true wireless earbuds
TWS shipments reached about 520 million units in 2024, and each generation demands smaller, clearer, longer‑lasting sound; Knowles’ integrated mic+tuning+packaging modules win on measured performance and fit this trend. High volumes sustain scale and complex multi‑component designs protect margins, while upfront R&D and customization are heavy but typically deliver payback within quarters as OEM adoption accelerates.
Voice processing algorithms for hearables
Noise suppression, beamforming and wake-word accuracy are now table stakes in hearables; global TWS shipments reached about 500 million in 2023, driving baseline demand for audio IP. Knowles’ software-layer voice algorithms sit atop its MEMS hardware, increasing bundle stickiness and OEM switching costs. As hearables add on-device AI (voice assistants, adaptive ANC), attach rates and ASPs rise, so invest to stay embedded in OEM roadmaps.
Premium hearing-health transducers
Premium hearing‑health transducers sit in Stars as aging populations (65+ reached 761 million in 2021, UN) and demand for premium devices sustain double‑digit ASP growth in high‑end mics/receivers; regulatory and clinical hurdles raise entry costs, preserving Knowles pricing power and long OEM relationships, so clinical partnerships and miniaturization leadership are critical.
- Market tailwinds: aging demographics
- Barriers: regulatory + clinical validation
- Moat: performance → long contracts
- Strategy: deepen clinical ties, lead miniaturization
Automotive in‑cabin audio capture
Cars are becoming rolling voice devices for calls, assistants and safety prompts, with OEMs specifying 4–8 cabin microphones on many 2024 models; ADAS and driver monitoring add 2–4 extra capture points per vehicle. Automakers demand low‑noise, high‑reliability MEMS mics that withstand heat, dust and 10+ years of use, pushing suppliers like Knowles into star growth as platforms are locked and scaled across model years.
- Market position: Stars — high growth, heavy OEM platform wins
- Spec trend: 4–12 mics/vehicle (voice + ADAS/monitoring)
- Product needs: low SPL noise, wide temp/dust tolerance, 10+ yr MTBF
- Strategy: lock platforms now, scale with model-year rollouts
MEMS mic leader: Billions shipped; TWS 520M, auto 4–12/vehicle
Knowles leads in MEMS mics with billions shipped; 2024 smartphone cycles and flagship 3–5 mic arrays sustain high ASPs and R&D-driven design wins.
TWS demand ~520M units in 2024; integrated mic+module wins raise ASPs and margins despite heavy upfront R&D.
Automotive adoption (4–12 mics/vehicle on many 2024 models) plus premium hearing-health growth make Stars high-growth; priority: lock platforms, clinical ties, miniaturization.

Cash Cows
High‑reliability capacitors for medical/defense
Mature, spec-heavy capacitors for medical and defense are sticky once qualified; customers prioritize reliability over novelty, stabilizing pricing. Predictable procurement tied to the US FY2024 defense budget of 858 billion supports forecastable demand and strong margins that fund new bets. Maintain high service levels and pursue incremental performance tweaks to retain share.
Legacy mobile MEMS variants
Legacy mobile MEMS variants are not on the newest nodes but continue shipping in volume into mid-tier phones; global smartphone shipments were about 1.16 billion in 2024 (IDC). Tooling is paid, yields are strong and operations efficient, delivering steady cash flows. Price erosion is gradual yet cash generation holds. Milk with tight cost control and selective SKU pruning.
Industrial/communications precision devices
Industrial/communications precision devices are cash cows for Knowles: long certifications and replacement cycles keep churn low, supporting steady PO flow and typically 5–10% annual revenue from spares and upgrades. Less glamour but dependable orders mean margins rise with modest process upgrades; the global industrial sensors/precision devices market was roughly $50B in 2024, justifying efficiency-focused investment rather than splashy features.
Micro‑speakers for established OEM programs
Micro‑speakers for established OEM programs have locked designs and multi‑year lifecycles, delivering predictable revenue and steady cash in 2024. Performance is good enough to minimize churn, so limited product‑driven growth keeps them cash cows rather than stars. Maintain immaculate supply operations and avoid unnecessary re‑engineering to protect margins.
- Locked designs → predictable revenue
- Good‑enough performance → low churn
- Limited growth, solid cash flow
- Priority: flawless supply, no needless re‑engineering
Mature audio codecs/voice processors
Mature audio codecs and voice processors at Knowles are embedded in legacy platforms with long tails, delivering steady royalty income and low support costs; in 2024 these tails continued to generate predictable cash flow while top-line growth remained capped.
Maintain compatibility and security updates only to preserve the clean cash stream and minimize R&D; royalties and after-sales support together sustain margin contribution despite limited expansion opportunities.
- Long tails: multi-year installed-base revenue
- Low support costs: minimal maintenance spend
- Royalties: recurring, accretive to cash flow
- Strategy: compatibility/security updates only
Capacitors, MEMS & sensors: defense $858B, phones 1.16B, industrial $50B
Mature capacitors, MEMS, industrial precision devices and micro‑speakers deliver steady margins: US FY2024 defense budget 858B supports defense demand; global smartphone shipments ~1.16B (2024 IDC); industrial sensors market ~$50B (2024). Focus on service, cost control, selective SKU pruning and minimal R&D for tails.
| Segment | 2024 metric | Priority |
|---|---|---|
| Defense capacitors | US budget $858B | Reliability/service |
| Mobile MEMS | 1.16B phones | Cost/yields |

Dogs
Low‑end commodity microphones
Low‑end commodity microphones are a classic Dogs: 2024 saw accelerated ASP compression and a race‑to‑the‑bottom pricing as new entrants undercut incumbents and buyers switch freely. Minimal product differentiation keeps churn high and cash tied up in low‑margin inventory, with returns thin and margins often barely covering variable costs. Exit low‑margin SKUs fast to stop cash bleed and redeploy capital to differentiated MEMS lines.
Standalone consumer speakers (non‑core)
Assemblies without an IP edge are being squeezed by ODM giants such as Goertek, AAC and Luxshare, which now control the majority of consumer speaker volume. Demand in standalone consumer speakers is choppy and increasingly promo-driven, pressuring ASPs and margins. Little room exists to win sustainably without proprietary acoustics or MEMS IP. Recommend divest or sunset non-core speaker assemblies to preserve capital.
Feature‑phone audio chipsets
Feature-phone audio chipsets are in a shrinking, price-sensitive segment—global feature-phone shipments fell to about 180 million units in 2024 (≈22% YoY) as smartphones exceed 84% share. Engineering investment yields low ROI and sustaining support diverts resources from growth areas; margins compress with ASPs down roughly 10%. Wind down SKUs and redeploy engineering and support talent into premium audio and MEMS growth pockets.
Generic industrial buzzers/alarms
Generic industrial buzzers and alarms are classic Dogs in Knowles BCG: highly substitutable commodity parts with few sustainable moats, competing largely on price. The segment is tender-driven and margin-light, diverting capital from higher-growth acoustic sensor and MEMS businesses. Recommend phasing out production as existing contracts expire and reallocating investment to differentiated product lines.
- Highly substitutable / low moat
- Tender-driven, margin-light
- Reallocate capital to higher-growth segments
- Phase out as contracts end
Over‑custom one‑off builds
Over‑custom one‑off builds drain NRE and ops bandwidth, with product proliferation studies showing 20% of SKUs often drive 80% of revenue while many bespoke items add 5–15% to operating costs (industry estimates, 2024). Hard to maintain and harder to price, these low-volume designs create portfolio clutter with limited strategic value. Recommend kill or migrate to standard platforms to recover margin and simplify support.
- Low strategic value
- High NRE burn
- Maintenance overhead
- Migrate or kill
Divest low-end mics, feature-phone chipsets and generic buzzers to stop cash bleed
Low‑end mics, non‑IP speaker assemblies, feature‑phone chipsets and generic buzzers are Dogs: low differentiation, margin erosion and high churn. Feature‑phone shipments fell to about 180 million units in 2024 (≈22% YoY) with ASPs down roughly 10%; ODMs now control the majority of speaker volume. Recommend divest, phase‑out or migrate to platforms to stop cash bleed.
| Segment | 2024 metric | ASP/margin | Action |
|---|---|---|---|
| Feature‑phone chipsets | 180M units (≈22% YoY) | ASPs ≈‑10% | Wind down |
| Speaker assemblies | ODM majority volume | Promo‑driven, low | Divest/sunset non‑core |
| Generic buzzers | Commodity, tender‑driven | Margin‑light | Phase out |
Question Marks
AI‑at‑the‑edge audio processors
On-device inference for wake words and noise removal is heating up as smartphone and hearables volumes remain >1 billion units in 2024, creating large addressable sockets for Knowles. Landing a few key OEM sockets could flip this Question Mark into a Star, but that requires heavy software investment and meeting tight sub-10mW power budgets in many form factors. Focus investment where attach rates are provable through pilots and signed OEM roadmaps.
Spatial audio modules for AR/VR
Headsets demand immersion and precise capture, driving interest in spatial audio modules as AR/VR headset shipments reached roughly 10 million units in 2024, highlighting strong product pull. Volumes remain uncertain and winners are not settled, with market share still consolidating across suppliers. Early design‑ins can compound quickly, turning small wins into scale advantages. Place selective bets with top platform players to capture outsized upside while managing risk.
Automotive cabin monitoring and safety mics
Regulation and new UX are nudging cabin monitoring adoption—some regions/OEMs target phased rollouts from 2025–2030—so timelines vary by market. Tech fit for Knowles MEMS mics and safety microphones is strong, though volume visibility remains unclear. Recent secure platform awards and established scale-manufacturing pathways de‑risk commercialization. If OEM traction lags, pivot to Tier‑1 bundles to regain pipeline momentum.
Health‑sensing microphones for wearables
Biometric capture via acoustics is promising but remains unproven at scale; clinical validation and app-ecosystem buy-in are required before broad adoption. If accuracy is defensible, average selling prices typically converge upward as clinical-grade features attract premium pricing. Recommend pilots with anchor customers, measuring attach rate and incremental revenue per device; wearable shipments exceeded 300 million units in 2024, indicating large addressable volume.
- Validation: clinical trials and FDA/CE pathways
- Market: >300M wearables shipped in 2024
- Commercial: pilot with anchor accounts, track attach and ASP uplift
Smart home far‑field arrays
Question Marks: smart home far‑field arrays face cooled category growth—unit expansion slowed to low single digits in 2024—but next‑gen assistants could re‑accelerate demand. Knowles can win on superior noise rejection and smaller form factor; the barrier is market share, not technology. Pursue test partnerships, avoid inventory risk with build‑to‑order.
- 2024: low single‑digit growth
- Strengths: noise rejection, size
- Focus: partnerships, no inventory
Sub‑10mW on‑device audio: win OEM pilots to capture >1B mobile/hearable sockets
Question Marks: on‑device inference and noise removal target >1.0B smartphone/hearable sockets in 2024 but need sub‑10mW SW/hw wins and signed OEM pilots to scale. AR/VR spatial audio (≈10M units 2024) and wearables biometrics (≈300M units 2024) offer upside if early design‑ins convert. Smart‑home arrays saw low single‑digit unit growth in 2024; pursue partnerships, avoid inventory.
| Segment | 2024 Volume | Key Metric | Action |
|---|---|---|---|
| Mobile/Hearables | >1.0B | sub‑10mW, OEM pilots | Target signed roadmaps |
| AR/VR | ≈10M | design‑ins | Selective platform bets |
| Wearables | ≈300M | clinical validation | Pilot anchors |
| Smart Home | low single‑digit growth | market share | test partnerships |
