The "SAE-20D" is capable of surface mounting, allowing for automatic placement on the circuit board and soldering via reflow (using lead-free solder), which can enhance the assembly efficiency of the circuit board for customers. One of the features of the "SAE-20D" is the incorporation of a three-dimensional sound hole (duct) on the back of the speaker, which facilitates the separation of sound from the front and back of the speaker, eliminating the need for design considerations for the rear space as previously required (patent pending). Despite being a compact speaker measuring 20mm x 20mm, it can achieve a sound pressure output of approximately 91dB* in the frequency range of 600Hz to 3,000Hz, addressing the needs for high sound pressure output across a wide frequency range. In terms of reliability, it can withstand environmental changes from -40°C to 105°C, and customization of impedance is also possible according to customer requirements. *For more details, please contact us.

The TMB series is an electronic sound buzzer with a built-in drive circuit that can be easily used as an alarm sound or operation sound by simply applying a DC voltage. (*The "TMB-05B" has a rated voltage of 5VDC, and the "TMB-12B" has a rated voltage of 12VDC.) The electronic sound buzzers "TMB-05B" and "TMB-12B" have improved heat resistance by 20°C compared to the conventional models "TMB-05" and "TMB-12," and the storage temperature range has also been expanded from -40°C to 105°C. Additionally, thermal shock resistance has significantly improved to 1,000 cycles. *For more details, please contact us.
