Little Genius not only has children's phone watches, but also Bluetooth headphones. The E5 open-back Bluetooth headset launched by Little Genius is unique in the headphone market with its innovative design. The E5 earbuds are physically adjustable and secure to the pinna with a twist clip for a secure fit. In addition, the E5's charging case is equally eye-catching, with a transparent case material and a diamond-cut shape to show a unique and personalized style. These ingenious structural design and appearance innovations make the Little Genius E5 stand out from similar products.
I love audio network recently through the dismantling of the in-depth understanding of the little geniusE5,Found that it has a built-in LPS microsource semiconductorLP6261Ultra-low quiescent current synchronous boost converter,This is a component used to boost the built-in battery of the charging case to charge the earbuds。
Whether it is the charging case or the earbuds body, the appearance is a highlight of the little genius E5. The charging case is first of all transparent, and the "electronic components" engraved on the surface can be seen from the front, which is very technological. The overall shape is inspired by the "Radiant" diamond cutting process, with a clear and linear appearance. The earphone body adopts an innovative physically adjustable ear clip design, and a hovering hinge structure is installed at the tail to fit different sizes of ear pinna.
In terms of functional configuration,Little geniusE5Equipped with exclusive sound field directional gain technology,Ensure that the sound is concentrated without sound leakage。 DRC tuning technology also enhances the E5's bass effect with more detail. The headset is 4.9 grams per ear, which is more comfortable to wear. It has a total battery life of 27 hours and also supports IPX4 life waterproofing. Little Genius E5 has two colors: dark mirror black box moon shadow white.
After the dismantling of the audio network, it was found that the little genius E5 charging box has a built-in 800mAh lithium battery, and its motherboard integrates overvoltage and overcurrent protection IC, boost inductor, LED indicator, charge and discharge managementAD type Flash microcontroller and boost converter and other components, among which the boost converter is from LPSMilp source semiconductorLP6261, which mainly plays a boost role.
LP6261 has TRUE OFF function, which can disconnect input and output under the condition of off and output short circuit, 1.2MHZ switching frequency can use small volume of inductance and capacitor, the switch pin adopts high-voltage 9V process, which can effectively absorb the high-voltage spike of the production capacity when the earphone is plugged and unplugged, and LP6261 has no whine sound in the full load capacity range (especially when light load).
The LP6261 consumes only 1UA of quiescent current at light loads, achieves up to 75% efficiency at 20uA load, and up to 93% conversion efficiency from 3.3V to 5V at 200mA.
