Abstract

The utility model discloses an acoustic lens-like direct radiator for loudspeaker, which comprises cylindrical body (3) and suspending edge (1). Front surface of the cylindrical body (3) is provided with upward-protruding reinforcement ribs (2). Said reinforcement ribs (2) are in radiation distribution from the root to the edge of the cylindrical body (3). Said reinforcement ribs (2) can change the propagation path of sound, similar to the lens with function of changing light path, thus helping to reduce the mutual interference and counteraction of sound waves and improve the frequency response of loudspeaker. Said direct radiator is used as both horn radiator for treble loudspeaker and vibrating membrane for bass loudspeaker. The utility model is adapted to loudspeaker for both non-professional and professional use.

Description

Loudspeaker Sound Lens Homology Sound Basin Radiator

Technical field

The utility model relates to electro-acoustic element, and loudspeaker techniques field especially is specifically related to the technical field of the vibrating diaphragm and the high pitch loudspeaker horn radiator of woofer.

Background technology

Loud speaker be a kind of be the transducer of voice signal with converting electrical signal, the playback that will finally realize sound by the vibration and the air radiation vibration of vibrating diaphragm, and we wish the efficient height of its transducing, in the frequency range of loud speaker distortion as far as possible little, frequency response curve is smooth as far as possible.

For woofer sound basin, require its intensity to want high, so just can reduce to cut apart vibration, reduce distortion.And common bass horn vibrating diaphragm, because the restriction of its structure, intensity is difficult to reach requirement, or will pay bigger cost on material just can reach requirement.

For high pitch loudspeaker, we wish that the sounding point that its sounding point of back and bass and Squawker are installed is in same plane, to avoid because of the distance different sound phase deviations that occur of high and low sound loud speaker with the audience, as shown in Figure 4.And common traditional high pitch loudspeaker all is the installation method that adopts surface plate, because the sounding point of different loud speakers is not in same plane, occurs phase distortion easily.

No matter be high pitch loudspeaker or woofer, in the radiation propagation process of sound, because the phase place difference of single loud speaker each point sound wave causes the mutual interference of sound wave easily.Treating method in the past is to install phase plug additional at the center of loud speaker to solve this problem, but this method is subjected to the restriction of cost and assembly technology.

The utility model content

[goal of the invention] the purpose of this utility model is, provides a kind acoustic lens homology sound basin radiator, to overcome above weak point.

[technical scheme] the technical solution adopted in the utility model is:

A kind of Loudspeaker Sound Lens Homology Sound Basin Radiator comprises cylindrical body and outstanding limit, and the strengthening rib strip of the positive oriented upper process of described cylindrical body, described strengthening rib strip are the radial radiation shape and distribute, and extends to the edge from the root of sound basin radiator.

The described sound basin subjectively bus of body is an exponential type curve.

Described sound basin radiator can adopt cone, PP basin, carbon fiber basin, metal basin, foaming basin to make.

[beneficial effect] the utility model both can be used to do the vibrating diaphragm of woofer, also can be used as the horn radiator of high pitch loudspeaker.

When the utility model was used as the vibrating diaphragm of woofer, because the booster action of the strengthening rib strip of its projection, the strength ratio of vibrating diaphragm was bigger, is not easy to occur cutting apart vibration.And, (be similar to the path that optical lens changes light, as shown in Figure 5), avoid the mutual interference of sound wave phase, reduced the distortion of loud speaker, make frequency response more smooth because the strengthening rib strip of its projection can change the radiation path of sound wave.

When the utility model is used as the horn radiator of high pitch loudspeaker, because the sounding point of high pitch loudspeaker is in identical plane with the sounding point of bass and Squawker, high pitch sound wave energy and middle pitch sound wave arrive audience's ear simultaneously, eliminate common middle and high sound because of the distance different time differences that cause of sounding point with the audience.Equally,, avoid the mutual interference of sound wave phase, reduced the distortion of loud speaker, make frequency response more smooth because the strengthening rib strip of its projection can change the radiation path (being similar to the path that optical lens changes light) of sound wave.And,, thereby improved the efficient of loud speaker because it has also played the effect of horn.

The utility model novel structure is installed and is made simply, can be widely used in various civilian, professional stage loud speakers.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described further:

As Fig. 1, a kind of Loudspeaker Sound Lens Homology Sound Basin Radiator, described sound basin radiator is made up of cylindrical body 3 and outstanding limit 1, the strengthening rib strip 2 of described cylindrical body 3 positive oriented upper process, described strengthening rib strip (2) is the radial radiation shape and distributes, and extends to the edge from the root of cylindrical body (3).Described outstanding limit 1 is hot pressed into ring-type by rubber, cloth, foamed plastic etc.Described strengthening rib strip 2 and cylindrical body 3 adopts one-time formed technology, according to clean slurry, soaking paste, pulping, pull an oar, drag for processing steps such as system, moulding, gluing, punching, check and make; Described sound basin radiator also can be made compound cone, overall plastic glue basin, glass fibre basin, metal awl basin etc.
