Want strong sound from small devices? These tiny speakers and receivers that deliver clear, loud audio and fit easily into any design.
Fitting high-quality sound into a small device is a common challenge that you might face as an audio design engineer. Compact devices require speakers that deliver clear, powerful sound while staying small, durable, and resistant to moisture or damage. Many over-the-ear and portable devices struggle to balance sound pressure, size, and protection, making it difficult to meet both performance and design requirements.
Same Sky’s Audio Group addresses this challenge with its expanded line of speakers and CMR receivers. Their CMR receivers deliver sound pressure levels (SPL) from 103 to 135 dB in compact sizes, some as small as 12 x 6 mm with profiles as low as 2 mm. The broader speaker lineup includes standard and custom frame sizes from 10 mm to 205 mm, with SPLs ranging from 72 to 135 dB, giving designers flexibility to match audio performance with space constraints across a variety of applications.
The receivers are available in round or rectangular frames, with solder pad or spring contact mounting. They support different cone types, handle nominal inputs from 0.003 to 0.2 W, and resonant frequencies between 100 and 550 Hz, with impedance options of 16, 30, 32, or 50 ohms. Certain models, such as the CMR-3466-1050SP-X7, CMR-12062S-67, and CMR-15062S-67, provide IPX7 ingress protection, making them suitable for moisture-prone environments. Some receivers also feature removable protective covers or built-in front grilles to safeguard the diaphragm.
The standard speaker range offers a variety of frame shapes, magnet types, and mounting options. This allows designers to integrate them quickly and easily into new or existing devices. By combining small form factors, high SPLs, and protective features, Same Sky’s expanded lineup makes it easier to design compact audio devices that do not compromise on sound quality or reliability.
