It closes.The passive acoustic radiator (15) is usually axially symmetric structure, is equivalent in coil-moving speaker unit and has subtracted magnet
With the electromagnetic drives such as voice coil.It wherein needs to consider the factors such as bore, vibrating diaphragm weight, design parameter is needed according to box body parameter
Matched design is carried out with the parameter of active broadband loudspeaker unit (8).
The overall work principle of the utility model is as follows：
Subwoofer (below 100Hz frequency ranges) part：It is wide by the active in babinet based on air transmitted inertia supercharging principle
The conversion of effective electroacoustic and radiation of ultralow frequency sound wave are realized in the collocation of band loud speaker unit (8) and passive acoustic radiator (15)；
Especially with the main original that excellent replaying bass is realized compared with small box and more small-bore active broadband loudspeaker unit (8)
Reason is to extend active broadband loudspeaker by passive acoustic radiator (15) (the particularly passive acoustic radiator of larger caliber)
The equivalent bore of unit (8), and the synchronized relation for ensureing acoustic vibration phase is matched by above-mentioned parameter.
Bass and middle pitch (100Hz~5000Hz) part：The active broadband loudspeaker unit (8) can be in wider frequency
There is flat frequency response characteristic in the range of band.
High pitch (more than 5000Hz) part：By using the cooperation of high-pass filter (11) and high pitch loudspeaker unit (9),
The good frequency response characteristic of high pitch frequency range can be realized using the component of lower cost.
For above-mentioned subwoofer (below 100Hz frequency ranges) part：
1) 1 active broadband loudspeaker unit (8) is installed simultaneously in a closed babinet (1) and 2 passive
Acoustic radiator (15, referred to as passive basin), wherein passing through for the second vibrating diaphragm (12) second plays ripple (13) in passive acoustic radiator (15)
(i.e. centring disk) support is installed in the second metal frame (14), to ensure enough elastic force and damping；
In each vibration period of the low frequency band of below 100Hz；
2) active broadband loudspeaker unit (8) starts (babinet forward before external electric signal under 1/4 Periodic signal drive
It moves outside), the and then movement into babinet (1) of passive acoustic radiator (15) time delay, at this moment air pressure starts to reduce in case, works as master
Before dynamic broadband loudspeaker unit (8) moves to during stop, at this moment passive acoustic radiator (15) moves to itself and can move
Intermediate point and resistance increase；
3) passive acoustic radiator (15) continues to move into babinet with inertia after, at this moment active broadband loudspeaker list
First (8) start back to move (in babinet) under 2/4 and 3/4 Periodic signal drive of external electric signal, and with passive acoustic radiator
(15) while back move to it is respective after stop, in case air pressure sharply rise to the critical point of a maximum；
4) while air pressure reaches maximum critical point in the case, active broadband loudspeaker unit (8) in the case air pressure with
The collective effect of rear 4/4 Periodic signal drive of external electric signal, air pressure and second plays ripple 13 to passive acoustic radiator (15) in the case
Outwards fierce movement simultaneously under elastic reaction, at this moment passive acoustic radiator (15) is produced with active broadband loudspeaker unit (8)
Raw acoustic pressure is all positive, and since acoustic pressure is overlapped mutually fruit, moment low-frequency sound pressure value is higher than common closed speaker sound pressure level 3dB
To more than 6dB.
It is (outstanding using passive acoustic radiator (15) in order to ensure to realize compared with high sound pressure level and compared with low distortion in subwoofer frequency range
It is larger caliber), equivalent to increase the Net long wave radiation bore of active broadband loudspeaker unit (8), while based on actively
The matching of broadband loudspeaker unit (8) and each parameter of passive acoustic radiator (15) makes passive acoustic radiator (15) can be with master
Dynamic loud speaker in phase vibration, thus ensure relatively low distortion while effective acoustic pressure grade is increased.
In order to which the utility model can preferably realize above-mentioned principle, the bore of the active broadband loudspeaker unit,
The passive bore of acoustic radiator, the vibrating diaphragm weight of passive acoustic radiator, several parameters of box sizes need reasonably combined relation.
Syntagmatic of the design parameter matching relationship with reference to shown in following table：
The high-pass filter (11) be mainly in series or in parallel to form by capacitance and resistance (again with high pitch loudspeaker unit string
Connection), it can also be separately formed by a capacitance.Specifically as shown in Fig. 6 a to Fig. 6 b, in Fig. 6 a, the high-pass filter (11) by
Capacitance C is formed, and is then connected with high pitch loudspeaker unit (9)；In Fig. 6 b, the high-pass filter (11) is by capacitance C and resistance
R is in series, then connects with high pitch loudspeaker unit (9)；In Fig. 6 c, the high-pass filter (11) is by capacitance C and resistance
R is in parallel to be formed, and is then connected with high pitch loudspeaker unit (9)；In Fig. 6 d, the high-pass filter (11) is by capacitance C and resistance
R1 connects and composition in parallel with resistance R2, then connects with high pitch loudspeaker unit (9).
The corner frequency value range of the high-pass filter (11) is 5kHz~10KHz.Frequency range more than corner frequency
According to the rate of decay of 6dB/ octaves, design parameter is according to the frequency response curve and high pitch of active broadband loudspeaker unit (8)
The impedance and sensitivity of loudspeaker unit (9) determines.General corner frequency selected as active broadband loudspeaker unit (8) exists
The response of mid-high voice frequency band frequency starts to tend to the frequency point after smoothly attenuation 3dB, makes voice unit actual playback frequency range and width
The reproduction frequency range of band loud speaker unit is connected just.The typical value of capacitance is 1.8 microfarads between 4.7 microfarads, with
The resistance value of capacitance series connection is generally between 1 ohm to 8 ohm, 4 Europe of value of the resistance in parallel with high pitch loudspeaker unit
Nurse is between 16 ohm, and design parameter is determined according to the characteristic impedance and sensitivity of high pitch loudspeaker unit (9), main function
Be appropriate attenuation high pitch frequency range sensitivity so that the sensitivity with bass frequency range is consistent, match its effective frequency range.
The utility model can realize that bass frequency range to the excellent sound reproduction of high pitch frequency range, realizes higher ultralow audio frequency
Ensure the distortion of extremely low audio playback while section sound pressure level, and advantageously ensure that in the feelings without using middle low frequency frequency divider
Select suitable broadband active speaker and high pitch loudspeaker combination that speaker can be made to possess the flat of 40Hz~20000Hz under condition
Smooth frequency response characteristic, and ensure very low acoustic replay distortion in broad frequency range, in addition, the speaker system phase
Production cost is relatively low, and small volume saves placement space.
It should be appreciated that the application of the utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come
It says, can be improved or converted according to the above description, all these modifications and variations should all belong to the appended power of the utility model
The protection domain of profit requirement.
