Abstract
The invention discloses a kind of stagewise acoustical couplings to export speaker, space is divided into former and later two cavitys by internal partition in the cabinet of speaker, built-in prime loudspeaker unit is mounted on the intracorporal partition of case and sends sound wave to back cavity, external rear class loudspeaker unit is mounted on the cabinet of back cavity and to cabinet external radiation sound wave, the rear class loudspeaker unit sound wave from prime loudspeaker unit received is coupled and will be coupled with the sound wave that itself is generated after total sound wave to cabinet exterior space radiant output.This speaker exports after compensating adjustment to the sound wave of external rear class loudspeaker unit by the sound wave of built-in prime loudspeaker unit, and the acoustical behavior of speaker output can be improved.
Description
Technical field
The present invention relates to a kind of audio signal replay equipment, especially a kind of speaker.
Background technique
Existing speaker is the direct radiant output sound wave of single or multiple loudspeaker units by being mounted on cabinet, this speaker
The sound wave of output is because be limited by loudspeaker unit and the specific physical constraints of cabinet itself, so that there are certain for the sound wave output of speaker
A little defects, such as the sound pressure level of sound wave output are not high enough；The low-frequency minimum frequency of sound wave is not low enough；The sound wave of certain frequency bands is owed
It lacks or excessive；Etc., these defects cause speaker that cannot reach preferable audio playback reduction degree or certain spies are not achieved
The requirement of fixed audio playback effect.
Summary of the invention
It is not high enough in order to solve such as output sound pressure level that existing speaker occurs in playback audio signal；Low-frequency minimum is not
It is enough low；The defects of sound wave of certain frequency bands is short of or is excessive, the present invention provides a kind of sound using stagewise acoustical coupling technology
Case generates auxiliary sound wave with built-in loudspeaker and is coupled to main sound wave that is defective or needing to adjust up, to solve
The defect problem of certainly existing speaker output sound wave.
The technical solution adopted by the present invention to solve the technical problems is: a kind of stagewise acoustical coupling output speaker, including
Cabinet；Housing interior volume is divided into the partition of forward and backward two parts cavity；Built-in prime loudspeaker unit and external rear class
Loudspeaker unit, built-in prime loudspeaker unit are mounted on the partition between the forward and backward cavity of box house, which makees
It is sent for auxiliary loudspeaker unit to back cavity and needs to do the auxiliary sound wave coupled, and rear class loudspeaker unit is installed as main loudspeaker unit
On the cabinet for the back cavity being located at before prime loudspeaker unit, for receiving auxiliary sound wave that prime loudspeaker unit sends over simultaneously
The sound wave is coupled on the main sound wave of itself generation and is exported by total sound wave after coupling to cabinet external radiation.
The beneficial effects of the present invention are: speaker of the present invention can generate auxiliary sound wave as needed and be coupled to auxiliary sound wave
On the main sound wave for needing to adjust, such as gain can be carried out to main sound wave；Decaying；Modulation；Delay；The processing such as reverberation, thus effectively
Such as sound pressure level for solving existing speaker is not high enough；Low-frequency minimum is not low enough；The sound wave of certain frequency bands is short of or excessively waits sounds
Playback of audio signals defect problem.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Attached drawing 1 is speaker schematic diagram of the present invention.
1. cabinet in figure, 2. back cavities, 3. partitions, 4. ante-chambers, 5. prime loudspeaker units, 6. rear class loudspeaker units
Specific embodiment
[embodiment 1]
The acoustical coupling of this stagewise exports speaker, including cabinet (1)；Back cavity (2)；Partition (3)；Ante-chamber (4)；Prime loudspeaker list
First (5)；Rear class loudspeaker unit (6), space is ante-chamber (4) and (2) two parts of back cavity, prime loudspeaker in partition (3) separation case body
Unit (5) is mounted on partition (3) to back cavity (2) and sends sound wave, and rear class loudspeaker unit (6) is mounted on the cabinet of back cavity (2)
It is upper and to cabinet exterior space radiative acoustic wave.
[embodiment 2]
The quantity of prime loudspeaker unit (5) and rear class loudspeaker unit (6) can be 1 or more, can be identical or not
Same loudspeaker unit.
[embodiment 3]
After the prime of ante-chamber (4) and prime loudspeaker unit (5) composition, with back cavity (2) and rear class loudspeaker unit (6) composition
Grade, and separate the partition (3) of forward and backward grade, it can be by increasing the series between forward and backward grade to be expanded into the structure type
Multistage acoustical coupling more than two-stage exports speaker.
[embodiment 4]
The cavity of ante-chamber (4) and back cavity (2) can be it is closed or unsealed, it is closed refer in cavity air not with
Outside is connected, and unsealed situation includes that air can be by one or more pipelines or opening and outside air phase in cavity
Air can be connected by one or more pipelines or opening between connection and two cavitys, and sound wave can pass through pipe
Road or opening carry out transmission
[embodiment 5]
The speaker can additionally add the other component other than the present invention；Function or feature.
