Description
Technical field
This utility model relates to audio amplifier, especially relates to a kind of symmetrical cell profile woofer.
Background technology
Audio amplifier is the terminal of whole sound system, and its effect is that audio frequency electric energy is converted into corresponding acoustic energy, and its spoke
It is mapped to space go.It is sound system and important ingredient thereof, because it is responsible for, and the signal of telecommunication is transformed into acoustical signal confession
The mission critical that the ear of people is directly listened to.
At present, the loudspeaker unit of existing woofer is usually arranged on the same face.When bass horn operation vibration,
Its vibrations dynamics concentrates on the same face of sound box, thus the vibrations of casing are bigger, and the vibrations of casing to be reduced will increase
Add the volume of casing.Additionally, the phase-reversing tube in existing woofer is generally the part of peripheral hardware, it is vertically fixed on the sidewall of casing
On, ultrathin audio amplifier as disclosed in the patent document that Authorization Notice No. is CN 202535534 U, although the audio amplifier of this structure
Bidirectional sounding can be realized, but the bass effect of audio amplifier is not good enough.And phase-reversing tube is arranged on the audio amplifier of box bottom, due to moulding and
Restriction in structure, audio amplifier is often unidirectional sounding, it is difficult to meet the two-way high requirement protecting the propagation of chastity degree tonequality.
For this reason, it is necessary to a kind of symmetrical cell profile woofer of research, meet what two-way high guarantor's chastity degree tonequality was propagated
Requirement.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, can realize that Bidirectional sounding, audio amplifier volume be little, audio amplifier case
Body vibration amplitude is little, the audio amplifier of sound clarity.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of symmetrical cell profile woofer, including casing, particularly, is provided with audio cavity in this casing, this audio frequency
Intracavity is provided with patch panel；This casing is provided with front panel and rear board, and this front panel and rear board are equipped with loudspeaker unit, should
Loudspeaker unit electrically connects with patch panel；2 symmetrical paraphase holes in comparative audio chamber it are additionally provided with in this casing；This paraphase hole bag
Include the first paraphase passage and the second paraphase passage being interconnected；This first paraphase passage is parallel to audio cavity and arranges and run through case
The bottom of body, communicates with the external world；This second paraphase passage is perpendicular to audio cavity and arranges and communicate with audio cavity.
Principle of the present utility model is as follows:
Audio-frequency module is arranged in the audio cavity of casing, by wiring and the loudspeaker list being arranged on front panel and rear board
Unit is connected, and makes audio amplifier be provided with the function of Bidirectional sounding.Two loudspeaker unit reverse symmetry are installed, and the dynamics of vibrations is symmetrical
In casing two sides, thus reduce the vibration amplitude of casing, and depending on the big I of casing is according to the size of loudspeaker, thus case
Body fixing fabric structure, in minimum scope, reaches small size effect.Signal is accessed to audio-frequency module, audio amplifier by patch panel
Work.Audio-frequency module, loudspeaker unit and patch panel all can use conventional design, thus reduce the production cost of sound box with sound.
The the first paraphase passage being arranged in casing is parallel to the bottom that audio cavity arranges and runs through casing, with extraneous phase
Logical；The the second paraphase passage being arranged in casing is perpendicular to audio cavity and arranges and communicate with audio cavity；First paraphase passage and
Second-speculation's phase passage is interconnected, and constitutes the paraphase hole of this audio amplifier, makes audio amplifier have preferably bass effect.First paraphase passage with
Second paraphase passage is one-body molded with casing and is arranged on box house, ensure that the first paraphase passage and second falls to greatest extent
Phase passage is relatively fixed with casing, it is to avoid the first paraphase passage and the second paraphase passage are the most impaired.
This audio amplifier can hang installation, also can be directly placed at use occasion.When this audio amplifier uses the mode directly placed, for
Avoiding the first paraphase passage to be in communication with the outside, the bottom of casing can be provided with the audio amplifier foot of several and casing integrated section,
Make between casing and placement location, to leave certain space, in order to air circulates.
This utility model has the advantages such as simple and compact for structure, bass acoustical quality is good, easy to use.The bass of this audio amplifier
During loudspeaker work, audio amplifier vibration amplitude is more more minor than general woofer, so that tonequality is apparent, clean, without noise.
