Weighing apparatus.
In some embodiments, network interface, mobile phone or computer are connected with Wifi modules；Described bluetooth module
The mobile phone or computer of upper connection.
The beneficial effects of the utility model are that have conveniently effect.By being then based on having developed into ripe WiFi
Wireless network, the advantages that making full use of WiFi wide coverages, transmission speed fast, strong antijamming capability, pass through wireless network pair
Play system carries out remote, quick and easy control；Remote high-fidelity transfer is carried out to audio signal.
Brief description of the drawings
Fig. 1 is functional-block diagram of the present utility model.
Embodiment
Utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of sound equipment, including casing, the loudspeaker that is provided with casing, and the circuit being connected with loudspeaker
Plate.Circuit board includes main control chip, the simulation input interface being connected with main control chip, the numeral input that is connected with main control chip connect
Mouth, the Wifi modules being connected with main control chip, the bluetooth module being connected with main control chip, the power amplification being connected with main control chip
Device, the frequency divider being connected with power amplifier, the speaker system being connected with frequency divider, and be provided with digital input interface
DA translation interfaces.Simulation input interface include RCA it is non-equilibrium or card tap balance.Be connected with Wifi modules network interface,
Mobile phone or computer；The mobile phone or computer connected on described bluetooth module.
Audio input provides decoding and control, eventually passes through power amplifier amplification and finally carries out sound weight by loudspeaker
Put, casing is that former mahogany is raw material, show audio amplifier it is high-grade with it is luxurious.Loudspeaker is raised using the high, medium and low sound of high-quality
Sound device, thoroughly sound is truly reduced, the advanced electronic element device materials of frequency divider, power amplifier are first using the electronics of hifi levels
Device, data signal enter play system and enter hifi power amplifiers by D/A converter module with analog signal, carry out most true
Power amplifier reduction.WiFi wireless modules, this is the most crucial technology of the wireless network audio frequency control technology, WiFi
The great advantage of (Wireless Fidelity, adopting wireless fidelity technology) is that transmission speed is higher, and energy adjust automatically bandwidth,
Can effectively Logistics networks stability and reliability, the WiFi-A31 modules that the design uses not only have WiFi work(
Can, and small size and the wireless connection of high data rate can be provided, it can be used for wireless iPAD, iPhone, Android system
Mobile device etc..Data storage device is that the WiFi-A31 is potentially applied, and mobile dress is concentrated mainly in Embedded application
Aspect is put, in the design, WiFi-A31 modules are controlled by 15 pins, 16 pin I2C and single-chip microcomputer stm805, audio solution
Code digital-to-analogue conversion is converted into analog signal and analog signal, Bluetooth signal by chips W M8988, and fiber-coaxial signal passes through
IC4051 chips are selected, and the left and right acoustic channels of final one group of signal enter HiFi power amplifiers, are entered by the speaker unit of high-quality
Row sound reproduction,
Wireless network audio frequency control key problem in technology is in Embedded Software Design that the design is opened using RealView MDK
Hair net part is write as Software Development Platform, embedded software using C voices.It is simple for structure concise, it is readable strong, while have tool
Most of ability of standby real time operating system, and by appropriate development after, various application occasions can be widely used in.System
System first initializes after starting, and WiFi-A31 modules can both use as router, can also be as the transmission of audio.Work as movement
When equipment is connected to WiFi-A31, and enter network settings, input existing wifi passwords, or net is directly inserted in netting twine
In network interface, it is possible to enter in whole network.Mobile device sets WIFI-A31 to be pushed in software, opens movement
The APP of equipment, it is possible to be controlled to audio, include the size of volume, the selection of source of sound, when WiFi instructions are judged as playing
The information of transmission is sent into FAT file system interface by microcontroller during instruction to be read out, it is possible to broadcast music
Put, it is similarly this reason to suspend and stop.Thus music playing system is set increasingly to simplify, high-speeding, intellectuality.
High-quality lossless music can also be heard while realizing that wireless network realizes audio frequency control.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to practical new
The protection domain of type.
