Description
Technical field
The utility model relates to the technical field of stereo set, is a kind of for the eqalizing cricuit on the linear array intermediate frequency unit specifically.
Background technology
Eqalizing cricuit also claims equalizer, being called for short EQ (English full name is the abbreviation of Equalizer), is a kind of audio signal processor, is applied to that the recoverable sound film vibration institute sound frequency that produces distorts in the loud speaker, obtaining flat response, thereby promote clearness and naturalness.
Because linear array will form linear array, frequency is more high, and the distance between the point sound source of composition linear array will be more little.So the high frequency unit of nearly all linear array audio amplifier has all adopted the form of waveguide, and a high frequency points sound source is become a plurality of point sound sources, dwindles the distance between the point sound source.But intermediate frequency unit is different from high frequency unit, and the intermediate frequency unit volume is bigger than high frequency unit, and the area of vibrating diaphragm is also big than high frequency unit, if also adopt the form of waveguide, not only cost height, most critical be all can not carry out in lower frequency limit and the upper limiting frequency of intermediate frequency.So a lot of companies adopt two intermediate frequency units to replace the method for an intermediate frequency unit, be that distance between the point sound source is reduced into original 50%, perhaps increase an acoustics diffuser plate in the intermediate frequency unit front, a point sound source is become two virtual point sound sources, and namely the distance between the virtual point sound source also is reduced into original 50%.But these processing methods, cost are all higher, are difficult to carry out lower frequency limit and the upper limiting frequency of intermediate frequency equally, are difficult to meet the requirement of current loud speaker pursuing high quality.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and cost is low, and is easy to process, makes linear array be used for eqalizing cricuit on the linear array intermediate frequency unit what the playback tonequality of SIF sound intermediate frequency section can be greatly improved.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of for the eqalizing cricuit on the linear array intermediate frequency unit, it is characterized in that: the described eqalizing cricuit body that is arranged on the intermediate frequency unit that comprises for the eqalizing cricuit on the linear array intermediate frequency unit, axial direction at the eqalizing cricuit body is provided with front, the back side, is provided with at least four axial sound source access openings at the eqalizing cricuit body.
Described eqalizing cricuit body front is circular flat, and the back side is arcwall face.
Described eqalizing cricuit body is made of cone table and the annular plate body that is located at the big end of cone table outer, wherein cone table and annular slab body form an integral body, the large end face of cone table and annular plate body constitute the front together, the arcwall face that described cone table small end face is shaped to indent constitutes the described back side, is provided with four axial holes from the front of eqalizing cricuit body to the back side and constitutes four sound source access openings.
Described four sound source access openings are respectively the first sound source access opening, rising tone source channels hole, the 3rd sound source access opening and falling tone source channels hole, the first sound source access opening and falling tone source channels hole left-right symmetric, rising tone source channels hole and the 3rd sound source access opening left-right symmetric.
Described rising tone source channels hole, the 3rd sound source access opening are that the vestibule of strip and the length direction of vestibule are arc, and the first sound source access opening and falling tone source channels hole are that two arc surfaces intersect the vestibule that constitutes.
The utility model compared with prior art has following beneficial effect:
By technical scheme described in the utility model, namely adopt eqalizing cricuit at the linear array intermediate frequency unit, particularly an intermediate-frequeney point sound source being invented four point sound sources is that distance between the virtual point sound source also is reduced into original 25%, the intermediate frequency upper limiting frequency is 4 times of employing same size intermediate frequency unit, be to adopt two intermediate frequency units to replace 2 times an of intermediate frequency unit, thereby a point sound source become 2 times of two virtual this modes of point sound source.This technical scheme that adopts linear array middle pitch unit eqalizing cricuit, make linear array intermediate frequency coverage reach 100Hz-2000Hz, basically comprised phonetic sound, the scope of most of musical instrument sound makes linear array obtain great lifting in the playback tonequality of SIF sound intermediate frequency section, simultaneously, adopt the with low cost of this technology, easy to process, make easily, be convenient to produce in batches.
