Background technology
Nowadays, people are higher and higher for the pursuit of sound quality, and many people are pursuing high-fidelity sound quality.Therefore, a
Hi-Fi sound-box is essential equipment on desktop naturally, there is the music of high-quality, and just must have can play the good of it
, the two is clearly complementary for speaker.
High-fidelity is exactly that can reset the essence of music to greatest extent, it is desirable that is exactly that Frequency Response wants flat even, sensitivity
Enough high, power is moderate.And existing speaker manufacture is limited by material and technique, can only reappear original in a certain range
Sound, and the existing high speaker volume ensured is generally bigger.
People are while pursuing the high-fidelity sound quality of speaker, it is also desirable to while speaker can play hi-fi music,
The lighter and handier volume the better.Therefore, Baffle Box of Bluetooth just comes into being.Baffle Box of Bluetooth refers to embedded with bluetooth chip, with bluetooth connection
The stereo set of the traditional wire rod connection of substitution is reached by being connect with bluetooths playback equipments such as mobile phone plane plate computer and notebooks
Conveniently purpose.But Baffle Box of Bluetooth is limited by its volume, most of music that cannot play out high-fidelity.
Utility model content
To solve the above-mentioned problems, the purpose of this utility model is to provide a kind of Hi-Fi sound-boxes, and the speaker is using micro-
Type loudspeaker, device volume are small；By the cooperation of Microspeaker and bugle, high pitch is effectively compensated for, ensure that the high of speaker is protected
True sound quality.
To achieve the above object, the utility model uses following technical scheme：
A kind of Hi-Fi sound-box, including the babinet of bottom, be arranged one jiao of babinet upper surface arc sound tube and be connected to
The horn-like bugle of arc sound tube upper end；Babinet is internally provided with control circuit board, frequency divider, subwoofer and full range
Loudspeaker, the upper end inside of arc sound tube or the inside of the small-bore end of bugle are embedded with Microspeaker, the power of Microspeaker
For 1 watt hereinafter, the horn mouth diameter of Microspeaker is at 20 millimeters or less；Control circuit board is electrically connected with frequency divider, frequency divider point
It is not electrically connected with subwoofer, Full-frequency trumpet and Microspeaker, control circuit board receives and processes audio signal, and frequency divider will
The audio signal that control circuit board is sent is separated into behind ultrahigh frequency, full range and subwoofer part ultrahigh frequency part being sent into miniature loudspeaker
, full range part is sent into Full-frequency trumpet and subwoofer is sent into subwoofer part.
Wherein, the control circuit board includes Bluetooth chip and power amplifier chips；Bluetooth chip is electrically connected with power amplifier chips, work(
It puts chip to be electrically connected with frequency divider, Bluetooth chip receives and decode audio signal, and power amplifier chips receive decoded audio signal
After be amplified after be sent to frequency divider.
Wherein, high pitch phase plug is arranged with above Microspeaker inside the bugle.
Wherein, the bugle is ceramic bugle.
The utility model has the advantages that：
The utility model is using the Microspeakers such as mobile phone Full-frequency trumpet, when exclusive use, is not appropriate for as ultrahigh frequency loudspeaker
Use, existing ultrahigh frequency loudspeaker volume is larger, is not suitable for the sound-box device of miniaturization, and the utility model is by will be miniature
Loudspeaker and bugle are used cooperatively, and realize the function of ultrahigh frequency loudspeaker, and sound frequency is high, compensates for the high pitch of entire speaker,
It ensure that the high-fidelity sound quality of speaker, while the effective volume for reducing whole device.

Specific implementation mode
The utility model is described in further details below in conjunction with the drawings and specific embodiments：
Referring to Fig. 1 to Fig. 3, a kind of Hi-Fi sound-box, including the babinet 1 of bottom, arc one jiao of 1 upper surface of babinet is set
Shape sound tube 2 and the horn-like bugle 3 for being connected to 2 upper end of arc sound tube；
The babinet 1 is internally provided with control circuit board, frequency divider 12 and babinet loudspeaker, and the control circuit board includes
Bluetooth chip 111 and power amplifier chips 112；The babinet loudspeaker include subwoofer 131 and the setting being arranged in 1 bottom of babinet
Full-frequency trumpet 132 in 1 one side wall of babinet.
Microspeaker 21 is embedded with inside the upper end of the arc sound tube 2, Microspeaker 21 can also be arranged small in bugle 3
The inside of bore end.The power of the Microspeaker 21 be 1 watt hereinafter, Microspeaker 21 horn mouth diameter 20 millimeters with
Under.In the present embodiment, the Microspeaker 21 is mobile phone Full-frequency trumpet.
