Abstract
A kind of countryside broadcast system, including signal input device, conversion modulator, transmitter and broadcast terminal, the broadcast terminal includes loudspeaker, the loudspeaker include sounding body, with first cover of sounding mates, it further include second cover, second cover is arranged on the outside of first cover, the hole communicated with second cover is provided on first cover, vibrating membrane is provided on the hole, the taper of first cover is identical as the taper of second cover, and first cover is longer than second cover.The intensity of acoustic wave in region, since what sound wave transmitted being closer, can will not influence this part audience and listen to less than the first intracorporal sound wave of cover between the first cover and the second cover.Therefore we can achieve in a certain range, the much the same effect of the volume that the audience of nearby and faraway hears.By looking after and guiding the position of baffle, our adjustable intensity for entering region sound wave between the first cover and the second cover.
Description
Technical field
The present invention relates to broadcast technology fields, more particularly, to a kind of countryside broadcast system.
Background technique
In the broadcast system in rural area, loudspeaker are main broadcast terminals, for audio model to be passed to audience.Especially
Outdoor loudspeaker are set, and in order to which audio signal is passed to audience as far as possible, loudspeaker are generally provided with a circular cone
The cover of shape.But this also brings some problems, exactly may feel ear-piercing from the closer audience of loudspeaker, but from loudspeaker
Remote audience can think that sound is too light again.
Summary of the invention
The present invention aiming at the shortcomings in the prior art, provides a kind of countryside broadcast system, can allow in certain distance
The sound that audience hears is similar.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals: a kind of countryside broadcast system,
Including signal input device, conversion modulator, transmitter and broadcast terminal, the broadcast terminal includes loudspeaker, the loudspeaker packet
Sounding body is included, further includes second cover with first cover of sounding mates, second cover is arranged described
On the outside of first cover, it is provided with the hole communicated with second cover on first cover, is provided with vibrating membrane on the hole,
The taper of first cover is identical as the taper of second cover, and first cover is longer than second cover.
In above-mentioned technical proposal, it is preferred that first cover and second cover are by the good material of sound insulation value
Material is made.
In above-mentioned technical proposal, it is preferred that further include baffle, strip-shaped hole is provided on the baffle, bolt passes through bar shaped
Hole is connected on first cover later, and the different location of the strip-shaped hole, adjustable institute are fixed on by the bolt
State the area that baffle covers the through-hole.
In above-mentioned technical proposal, it is preferred that the baffle is longitudinally disposed along the side wall of first cover.
In above-mentioned technical proposal, it is preferred that the region of 5m or more from the ground is arranged in the loudspeaker.
Compared with prior art, the beneficial effects of the present invention are: due to the stronger sound insulation capabilities of the first cover, only from vibration
The partial sound that dynamic film enters region between the first cover and the second cover can just pass to audience, be located at the first cover and the
The intensity of acoustic wave in region can cover intracorporal sound wave less than first between two covers, but since what sound wave transmitted being closer,
It will not influence this part audience to listen to.Therefore we can achieve in a certain range, the sound that the audience of nearby and faraway hears
Measure much the same effect.By looking after and guiding the position of baffle, we are adjustable to enter region between the first cover and the second cover
The intensity of sound wave.
Detailed description of the invention
Fig. 1 is schematic diagram of the invention
Fig. 2 is the schematic diagram of loudspeaker.
Fig. 3 is the schematic diagram of baffle.
Fig. 4 is the schematic diagram when present invention uses.
Specific embodiment
Present invention is further described in detail with attached drawing With reference to embodiment.
As shown in Figures 1 to 3, a kind of countryside broadcast system, including signal input device, conversion modulator, transmitter and wide
Terminal is broadcast, the broadcast terminal includes loudspeaker, and the region of 5m or more from the ground is arranged in the loudspeaker, and the loudspeaker include sounding
Body 1 matches the first cover 21 with the sounding body 1, further includes second cover 22, and second cover 22 is arranged in institute
21 outside of the first cover is stated, is provided with the hole 201 communicated with second cover 22, the hole 201 on first cover 21
Inside it is provided with vibrating membrane 202.
First cover 21 and the second cover 22 are made of the good material of sound insulation value, the cone of first cover
Degree is identical as the taper of second cover, and first cover is longer than second cover.
It further include baffle 3, the baffle 3 is longitudinally disposed along the side wall of first cover 21.It is arranged on the baffle 3
It is connected on first cover 21 after thering is strip-shaped hole 31, bolt 4 to pass through strip-shaped hole 31, institute is fixed on by the bolt 4
The different location of strip-shaped hole 31 is stated, the adjustable baffle 3 covers the area of the through-hole 201.
As shown in figure 4, in use, the sound that sounding body 1 issues is transmitted to farther away region by the first cover 21, due to
The length of first cover is longer than the second cover, therefore has the function of certain convergence sound wave, therefore in a certain range farther out
Audience can also be audible.Simultaneously for for closer audience, due to the stronger sound insulation capabilities of the first cover, only from vibration
The partial sound that film enters region between the first cover and the second cover can just pass to audience, be located at the first cover and second
The intensity of acoustic wave in region can cover intracorporal sound wave less than first between cover, but since what sound wave transmitted being closer, also not
It will affect this part audience to listen to.Therefore we can achieve in a certain range, the volume that the audience of nearby and faraway hears
Much the same effect.By looking after and guiding the position of baffle, we are adjustable to enter region sound between the first cover and the second cover
The intensity of wave.
