Abstract
The utility model discloses a kind of ultra-thin double passive radiator sound equipments of automobile, it is characterized in that, the loudspeaker that is provided with including casing, in casing, the power amplifier being provided with a speaker, the first passive radiator and the second passive radiator being provided with casing, and the airduct mouth being provided with casing.The utility model, which has effectively, solves the problems, such as that casing is too small and airflow noise is excessive, is highly suitable for using inside automobile, can install under narrow seat, moreover it is possible to the effective effect for increasing low frequency amount sense.
Description
Technical field
It the utility model is related to a kind of ultra-thin double passive radiator sound equipments of automobile.
Background technology
At present, the automobile audio of market is mainly to swing to based on case.During due to using narrow space, casing is too small can not
Phase-reversing tube is installed, and swing to the airduct of case there is also airflow noise it is excessive the problems such as.
Utility model content
In view of the above problems, the purpose of this utility model, which is to provide, a kind of effective solves that casing is too small and airflow noise mistake
The problem of big, it is highly suitable for using inside automobile, can installs under narrow seat, moreover it is possible to effective increase low frequency amount sense
The ultra-thin double passive radiator sound equipments of automobile.
To achieve the above object, a kind of ultra-thin double passive radiator sound equipments of automobile provided by the utility model, its feature exist
In, including casing, be provided with casing loudspeaker, be provided with a speaker power amplifier, be provided with casing
One passive radiator and the second passive radiator, and the airduct mouth being provided with casing.Thus, casing is high intensity cast aluminium alloy
Material, volume is very small, very thin, also uses reinforcement design, casing is very firm, divides upper shell and lower house two parts group
Into upper shell is mounted with loudspeaker unit, and passive radiator module, and radiator modules are connected by a support, whole biradial
Device and support form the airduct of a rectangle.When air in loudspeaker unit motion, compression box body, air release pressure, meeting
Two radiator motion is driven, the pressure of air in casing can be reduced, radiator is not done with the compression of air with release
Most violent motion, the controllability of so passive Caloris Basin can get a promotion, and the utility model, which has, causes ultra-thin casing
Equally obtain simple and honest, strong sense of hearing effect.A kind of double passive radiator sound systems include active speaker unit and
Two passive radiators, passive unit is generally similar with active speaker unit profile, and its cross sectional shape can be square, rectangular
Shape, circle or ellipse, it is also possible to make other irregular shapes, passive radiator does not have voice coil loudspeaker voice coil and drive magnet.It only has
One cone, get along well any voice coil loudspeaker voice coil or circuit are connected, and cone needs additional bob-weight, and counterweight is in passive radiator design link
Important step, final sounding effect being directly connected to, the vibrating diaphragm ring at cone edge and the air being enclosed in casing are formed,
The motion of passive radiator is carried out by the promotion of casing interior air-flow.By the regulation of different counterweights, passive radiator can be
Resonated on different frequency, passive radiator is usually used to adjustment ultralow frequency part.The frequency of fadings of radiator case is usual
It is that every octave reduces 18dB, allows the sound of both main loudspeaker unit and passive radiator to be superimposed enhancing, it should to carry out
Strict same-phase motion.Parameter, the pliable and counterweight of double passive radiators, tank-volumes of master unit loudspeaker etc. can be passed through
Etc. coordinate design, system low frequency can possess more preferable transient response, allow surge low frequency more to have levels.
The beneficial effects of the utility model are that have to solve the problems, such as that casing is too small and airflow noise is excessive, are highly suitable for
Use, can be installed under narrow seat inside automobile, moreover it is possible to the purpose of effective increase low frequency amount sense.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of ultra-thin double passive radiator sound equipments of automobile, including casing 2, raising one's voice of being provided with casing 2
Device 3, the power amplifier 6 being provided with loudspeaker 3, the first passive radiator 4 being provided with casing 2 and the second passive radiation
Device 5, and the airduct mouth 1 being provided with casing 2.Casing 2 is high intensity cast aluminum alloy material, and volume is very small, very thin, also makes
With design is strengthened, casing 2 is very firm, divides upper shell and lower house two parts to form, and upper shell is mounted with loudspeaker unit, and
Passive radiator module, radiator modules are connected by a support, the airduct of whole two radiator and support one rectangle of formation.
When the unit motion of loudspeaker 3, air in casing 2 is compressed, when air discharges pressure, two radiator can be driven to move, can reduced
The pressure of air in casing 2, radiator is set not do most violent motion with release with the compression of air, so passive radiation
The controllability of basin can get a promotion, and the utility model, which has, causes ultra-thin casing 2 equally to obtain simple and honest, strong sense of hearing effect
Fruit.A kind of double passive radiator sound systems include a loudspeaker 3 and two passive radiators, and passive unit is usual and raises one's voice
The profile of device 3 is similar, and its cross sectional shape can be square, rectangle, circle or ellipse, it is also possible to make other irregular shapes
Shape, passive radiator do not have voice coil loudspeaker voice coil and drive magnet.It only has a cone, and get along well any voice coil loudspeaker voice coil or circuit are connected, and cone needs
Additional bob-weight is wanted, counterweight is the important step in passive radiator design link, is directly connected to final sounding effect, cone
The vibrating diaphragm ring at edge and the air that is enclosed in casing 2 are formed, the motion of passive radiator by the interior air-flow of casing 2 promotion and
Carry out.By the regulation of different counterweights, passive radiator can be resonated on a different frequency, passive radiator generally by with
To adjust ultralow frequency part.The frequency of fadings of radiator case is typically that 18dB is reduced per octave, to allow loudspeaker 3 and passive
The sound superposition enhancing of both radiators, it should carry out strict same-phase motion.Can be by the parameter of loudspeaker 3, double passive
The pliable and counterweight of radiator, the volume of casing 2 etc. coordinate design, system low frequency can possess more preferable transient response, allow surge
Low frequency more has levels.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to practical new
The protection domain of type.
