Same Sky’s Audio Group has expanded its speaker portfolio with additional receiver models intended for over-the-ear applications. The CMR receiver family targets compact mechanical envelopes while providing a wide acoustic output range, with sound pressure levels specified from 103 to 135 dB when measured using an artificial ear.
The new receivers are offered in package sizes as small as 12 × 6 mm with profiles down to 2 mm. Mechanical options include round or rectangular frames, solder-pad or spring-contact mounting styles, and multiple cone constructions to support different acoustic and integration requirements.
Electrical and acoustic specifications vary by model, including nominal input power from 0.003 W to 0.2 W, resonant frequency from 100 Hz to 550 Hz, and impedance options of 16, 30, 32, or 50 Ω. For designs where moisture exposure is a concern, the CMR-3466-1050SP-X7, CMR-12062S-67, and CMR-15062S-67 are rated IPX7. Some variants add diaphragm-protection features such as a removable protective cover or an integrated front grille to reduce the risk of mechanical damage during assembly and use.
The CMR receiver models are available immediately, with pricing starting at $0.98 per unit at 100-piece quantities through distribution. Lead times range from stock to 12 weeks, depending on model and availability, with OEM pricing available directly from the supplier. Engineering resources and selection tools are also provided through the company’s speaker resource library.
