Description
Technical field
The present invention relates to stereo set technical field, be specifically related to a kind of power and dynamically regulate sound equipment.
Background technology
Along with the material life of expanding economy people is more and more abundanter, gradually starting to focus on the enjoyment of spirit level, appreciating music is a kind of all-ages ergasia;The sound equipment of a kind of high-quality increases many enjoyment can to the appreciator of music.Music is enjoyed and is necessary that music player devices, and the visual plant that sound equipment is enjoyed as people's high-quality music, its performance determines tonequality and the audio of music.People are when buying sound equipment, and the price of music effect and sound equipment is the key factor that people consider.Existing tradition sound equipment is due to the relation of this body structure, it is proportional that it plays the quality of music and its volume, loudspeaker watt level, that is the sound equipment of quality better often volume ratio is bigger, and the little sound equipment of volume is often poor with regard to tonequality audio, being exactly that cost performance ratio is relatively low on the whole, consumer cost is high.
Summary of the invention
The present invention is directed to existing acoustic product cost performance low, the problem that consumer cost is high, it is provided that a kind of tonequality audio is good, and the power that consumer cost is low dynamically regulates sound equipment.The technical scheme is that
A kind of power dynamically regulates sound equipment, and including casing, loudspeaker and circuit board, described loudspeaker are fixed on casing, and circuit board is arranged at cabinets cavity;Described circuit board includes power subsystem, power amplifier unit, interface unit, power adjustment unit and CPU processing unit, and described power subsystem provides power supply for whole sound equipment;Described interface unit is connected with CPU processing unit, is used for receiving audio file;Described CPU processing unit is connected with loudspeaker by audio frequency processing circuit, power amplifier unit;Described power adjustment unit connects CPU processing unit and power amplifier unit respectively;CPU processing unit is additionally provided with for detecting input audio frequency and the testing circuit of amplitude.
As currently preferred technical scheme, described power adjustment unit is that dynamic power regulates unit, CPU processing unit driven by program dynamically regulate power amplifier unit.
Further, described circuit board also includes remote control module, can be controlled sound equipment by the APP software of smart mobile phone, including the transmission operation such as file, broadcasting.
Further, described interface unit includes USB interface, SD card interface, Line in interface, cable interface and radio receiving unit, input audio file can be received, it is also possible to by wireless network reception input audio files such as bluetooth, wifi by legacy interfaces such as USB.
Further, described sound equipment is additionally provided with display screen, is used for showing the information such as audio frequency broadcasting and mode of operation.
Further, described box house uses multi-chamber structure, preferably two chambers, and owing to size and the structure of each chamber are different, its resonant frequency is different, produces multiple resonance, compares tradition sound equipment and has bigger bandwidth.
Advantages of the present invention:
The present invention is by increasing testing circuit detection input audio frequency, amplitude, controlled power adjustment unit by CPU processing unit and dynamically regulate power, optimize the low frequency playing function of sound equipment, it is allowed under equal tonequality audio index, power is lower, volume is less, reduces consumer cost, more conforms to the consumption demand that people are present;Present configuration design is more scientific and reasonable, takes full advantage of the confined space of sound equipment, improves broadcasting tonequality and the audio of sound equipment, is effectively improved the performance of sound equipment.

Detailed description of the invention
Embodiment:
Below in conjunction with the accompanying drawings the present invention is described in detail.
As shown in Figure 1: a kind of power dynamically regulates sound equipment, and including casing, loudspeaker and circuit board, described loudspeaker are fixed on casing, and circuit board is arranged at cabinets cavity;Described circuit board includes power subsystem, power amplifier unit, interface unit, dynamically regulation unit and CPU processing unit, power subsystem provides power supply for whole audio amplifier, interface unit is connected with CPU processing unit, for receiving audio file, input audio file can be received by legacy interfaces such as USB, can also pass through bluetooth, the wireless network such as wifi receives input audio file;CPU processing unit is connected with loudspeaker by audio frequency processing circuit, power amplifier unit;Dynamically regulation unit connects CPU processing unit and power amplification circuit respectively;CPU processing unit also includes for detecting input audio frequency, the testing circuit of amplitude.
When the present embodiment plays audio frequency, CPU processing unit receives input audio signal by interface unit, the audio signal of input is detected by testing circuit, when meeting, for detecting, the input audio signal being previously written CPU processing unit processes condition, CPU processing unit output control signal, control dynamically regulation unit and dynamically regulate the output of power amplifier unit, optimize the LF-response curve of loudspeaker, the most temporary optimization loudspeaker responding ability to low frequency audio signal, when input audio signal recovers high frequency, CPU processing unit output order controls dynamically regulation unit and cancels the dynamic regulation to power amplifier unit, loudspeaker recover normal operating conditions.The normal frequency response curve of loudspeaker and the contrast of dynamic frequency response curve are as shown in Figure 2, it can be seen that the present embodiment is under equivalent specifications loudspeaker, and it is the most relative with audio preferable that the response of low-frequency range is better than the sound equipment of general structure, the i.e. tonequality of the present embodiment sound equipment.Alternatively under the requirement of same tonequality and audio, can use less loudspeaker for the relatively conventional structure of the present embodiment, be possible not only to sound equipment and be made relatively smaller, and power is lower comparatively speaking, energy consumption is less.
As preferably, the present embodiment also includes remote control module, can be controlled sound equipment by the APP software of smart mobile phone, including the transmission operation such as file, broadcasting.
Further, sound equipment is provided with display screen, is used for showing the information such as audio frequency broadcasting and mode of operation.
As preferably, the present embodiment sound equipment is internal uses two chamber structures, and owing to size and the structure of each chamber are different, its resonant frequency is different, produces two resonance, as shown in Figure 3.Therefore, the present embodiment compare in equal space tradition sound equipment there is bigger bandwidth.
Below only preferred embodiment of the present invention is described, but is not to be construed as limitations on claims.The present invention is not only limited to above example, and its concrete structure allows to change, and in a word, all various changes made in the protection domain of independent claims of the present invention are the most within the scope of the present invention.
