Description
Technical field
It the utility model is related to sound technique field, more particularly to full range HiFi Bluetooth audio devices.
Background technology
Existing Bluetooth audio device is mostly a phonation unit, because the effective frequency range of single loudspeaker is limited, it is difficult in full range
Section range playback audio signal.Loudspeaker with bass performance can not reset treble audio signal, have raising for high pitch performance
Sound device can not reset bass audio signal.So the tonequality to sound equipment brings very big influence.
Utility model content
In order to solve the above technical problems, the utility model proposes a kind of full range HiFi Bluetooth audio devices, including cylindricality casing,
The cylindricality tank ends are respectively equipped with passive basin, and internal symmetry is provided with two groups of loudspeaker groups, and the loudspeaker group includes low
Sound unit speaker and voice unit loudspeaker, the bass unit loudspeaker group is disposed adjacent and bottom is provided with bluetooth PCB
Plate, lithium battery and jack-plug socket；The cylindricality casing is provided with metal truss.
Preferably, it is provided with the strong magnetic of neodymium iron boron in the voice unit loudspeaker and bass unit loudspeaker.
Preferably, the bass unit loudspeaker is provided with main vibrating diaphragm and suboscillating membrane.
Preferably, the voice unit loudspeaker is provided with fabric ball type vibration membrane.
The utility model proposes full range HiFi Bluetooth audio devices have following beneficial effect：Design bass unit and high pitch list
Member, effective frequency range cover 20Hz to 20KHz, reset all audio signals of human ear audible range；Passive basin is designed in sound equipment both sides,
Extend reproduction frequency range of the sound equipment in bass domain；The Bluetooth audio device speaker unit positional symmetry, sound discharge more placed in the middle, nothing
It is inclined to mechanical stiffness.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described.
Fig. 1 is internal structure schematic diagram of the present utility model；
Fig. 2 is external structure schematic diagram of the present utility model；
Wherein, 1- cylindricalitys casing, the passive basins of 2-, 3- bass unit loudspeakers, 4- voice unit loudspeakers, 5- wire nettings
Frame, 6- suboscillating membranes, the main vibrating diaphragms of 7-, the fabric ball type vibration membranes of 8-.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
As depicted in figs. 1 and 2, the utility model proposes a kind of full range HiFi Bluetooth audio devices, including cylindricality casing 1, institute
State the both ends of cylindricality casing 1 and be respectively equipped with passive basin 2, internal symmetry is provided with two groups of loudspeaker groups, and the loudspeaker group includes low
Sound unit speaker 3 and voice unit loudspeaker 4,3 groups of the bass unit loudspeaker is disposed adjacent and bottom is provided with bluetooth
Pcb board, lithium battery and jack-plug socket；The cylindricality casing 1 is provided with metal truss 5, according to the acoustics design of sound equipment, design gold
Belong to shell as framework, ensure that stabilized structure is firm.Metal shell two sides are designed with two passive basins 2, extend sound equipment low
The reproduction frequency range of range, box house is from center to two side directions are designed with bass unit loudspeaker 3, voice unit is raised one's voice
Device 4 and passive basin 2, effective frequency range cover 20Hz to 20KHz, reset all audio signals of human ear audible range.Two basses
The bottom design of unit speaker 3 has bluetooth pcb board, lithium battery and jack-plug socket.Whole casing good leak tightness, accomplishes high guarantor
Very, high tone quality.
Preferably, the strong magnetic of neodymium iron boron, the bass are provided with the voice unit loudspeaker 4 and bass unit loudspeaker 3
Unit speaker 3 is provided with main vibrating diaphragm 7 and suboscillating membrane 6, and the voice unit loudspeaker 4 is provided with fabric ball type vibration membrane 8, four
Loudspeaker uses the strong magnetic of neodymium iron boron.For bass unit loudspeaker 3, the mechanical stiffness of strong magnetic energy increase woofer, it is low to raise weight
Sound, vibrating diaphragm include main vibrating diaphragm 7 and suboscillating membrane 6 so that effective frequency range covering fs~10kHz of bass unit loudspeaker 3；High pitch list
First loudspeaker 4, which designs, uses cloth ball-type vibrating diaphragm, and high pitch is penetrating limpid；Passive basin 2 further improves stress tonequality.
A variety of modifications to embodiment will be apparent for those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments in the case where not departing from spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
