PowerWise technology-based "means" God of TCM Bluetooth design

Overview

Jingyue said: "the twelve laws as sacred, you can pass to the ground and hop gods.

"The gods by mind control, through the rotation of the yin and Yang Tai Chi, need music itself of yin and Yang of lifting to achieve, to play" Leda and of heaven and Earth, and man touches, but volatile gas blood, circulation spirit ". Chinese music therapy music content taken from nature, in the Palace's corner with feather formed on the basis of various Yun Qu (tuning), various changes of the "transfer" to lift as a basic form of yin and Yang. Chinese music therapy to help restore the balance of yin and Yang, the human body in order to achieve the purpose of rehabilitation and psychological. Massage therapy is a non-drug therapy, in line with the principle of Meridian, which is the traditional three yin, Yang theory. Through specific acupoints massage to stimulate the meridians Zang, dredging, enhance metabolism, adjust the human physiological function, enhance the immune system function and disease prevention, cure diseases, to, health care, for health purposes.

Bluetooth (Bluetooth) technology, is actually a short distance, low-cost wireless transmission technology.

From the current application, because Bluetooth small size, low power, its application is not limited to, computer peripherals, almost can be integrated into any digital device, effectively simplify the handhelds, laptops, and mobile phones, mobile phones and other mobile communication terminal device communication.

"God means" medicine and its overall design Bluetooth Terminal

"Chinese medicine God means" product is a traditional Chinese music therapy and massage therapy, the use of advanced microelectronic technology, through Bluetooth wireless transmitter to music therapy selected music transfer, Bluetooth is based on the PowerWise technology design, a portable device with high efficiency and energy saving features, through vivid audio and placed in a specific point of massage motor synchronous function to reach the dredging of the Meridian, rehabilitation, "Chinese medicine God means" product effective cultural, health, science and technology, and other fashion element fusion.

"Chinese medicine God refers to the" product key from the master software Magic finger, Bluetooth wireless transmitter and Bluetooth made up of three parts, of which the master software Magic finger interface as shown in Figure 1, including Bluetooth connection, recording guidance, massage relax, play instructions, etc.

Bluetooth connection control Bluetooth adapter and God means of Bluetooth module to connect and pairing, recording guidance for recording the doctor's advice and save into the corresponding audio files for easy Bluetooth transmission. Play guidance call recording medical supervision is recommended for users with the appropriate medical action, massage relax select doctor specified easily soft music, music therapy given to users.

PowerWise technology based Bluetooth function unit

Energy efficiency is the key to success or failure of the system design, depending on the system architecture, performance, function, volume and power consumption 4 important indicators tradeoffs all factors make a choice, make sure that every unit of the power to bring out the maximum performance.

Therefore, high-performance components. United States National Semiconductor PowerWise products at present a total of approximately 300 range of integrated circuits, were all belong to the energy-efficient chip to help improve the energy efficiency of the system, enabling low power consumption, strong thermal, small volume and longer battery life and other characteristics. "Chinese medicine God means" Bluetooth Terminal is based on the technical design of the portable device PowerWise, use of United States National Semiconductor's PowerWise series LM49370, LM4570, LM4675 and LP3952 etc devices with high efficiency and energy saving features, its structure diagram shown in Figure 4

Audio power amplifier using PowerWise products LM49370, belonging to the Boomer audio amplifier series audio subsystem, its characteristics are using spread spectrum technology, extremely low electromagnetic interference, and a built-in class d speaker amplifier, dual-mode stereo headphone amplifier and supports Bluetooth transceivers and dedicated interface, its internal block diagram as shown in Figure 5

Figure 5 audio power amplifier chip LM49370 internal block diagram

Stereo loudspeaker uses the PowerWise LM4675 series, a 2.65W Mono class-d audio power amplifier, it has the advantages of using spread spectrum technology, extremely low electromagnetic interference, do not need an additional filter, its internal block diagram shown in Figure 6

Figure 6 stereo loudspeaker chip LM4675 internal block diagram

Color LED drive adopts LP3952 PowerWise products, with sound and light synchronization feature 6-channel color LED driver IC, all LED drive current is 300mA, its internal block diagram shown in Figure 7

For portable products, system power consumption is the manufacturer needs to be one of the first concern, the "Chinese medicine God means" Bluetooth Terminal is based on the PowerWise technology design with a series of PowerWise Adaptive voltage scaling (AVS) and threshold voltage regulator, digital logic IC work and leakage power consumption automatically minimized, while maintaining minimal system overhead.

Bluetooth Terminal under separate processing unit practical work need to adjust its power supply, to reduce power consumption.

Conclusions of the

"Chinese medicine God means" design of Chinese music therapy and massage therapy, "dramatic" provides clear channel, and mental health rehabilitation.

Their Bluetooth devices using the PowerWise, these devices have built-in PowerWise multiple independent operations of processing units, sometimes they all work at full speed, but sometimes some of the features are idle or turned off. Due to independent management of the modules of the power supply, so that the system power consumption to achieve optimal.
