Micro Speaker and Balanced Armature Receiver Patents: Who Holds the Diaphragm and Magnet-Circuit Claims
Four assignees account for all 24 records in scope. there is no long tail here — the field is fully covered by a small ranked group, with one leader well ahead of the rest. Filings were absent in 2017, built through the early 2020s, peaked at 11 records in 2022, then dropped to 2 by 2024 — a decline of 71% over that three-year window. Because publication trails filing by roughly 18 months, the 2025 and 2026 figures are not yet representative and should not be read as a continuation of the decline.

Common questions about this landscape
Who holds the most patents on balanced armature receivers?
In this dataset of 24 records, one assignee holds 21 of them, making it by far the dominant filer in balanced armature receiver design. The remaining three ranked assignees account for the rest of the corpus with far smaller counts. Anyone evaluating freedom to operate in this space should treat that leader’s claim portfolio as the primary reference point rather than spreading review evenly across all four ranked parties.
Is the micro speaker and receiver acoustic design field still growing?
Filing activity rose to a peak of 11 records in 2022 and had fallen to 2 by 2024, a 71% decline over that three-year span. Because patent publication typically lags filing by around 18 months, the 2025 and 2026 figures in this dataset are still incomplete and should not be read as confirming a continued decline. The safest read is that filing has cooled from its 2022 peak through the last complete year of data, 2024.
What technology areas dominate the patent claims in this space?
H04R, the loudspeaker and audio transducer classification, covers 91.7% of the 24 records in scope, making this an overwhelmingly transducer-mechanics-focused corpus. Claims concentrate on diaphragm structure, magnet circuit design and related mechanical features rather than on downstream audio signal processing. A filer looking for adjacent, less-crowded ground would look outside core H04R diaphragm and armature claims.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Micro Speaker and Receiver Acoustic Design covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
