Abstract
The utility model relates to an electric-type high pitch loudspeaker, which comprises a vibrating diaphragm, a voice coil, a front pole plate and a face plate, wherein, the voice coil is connected with the vibrating diaphragm; the face plate comprises a bottom plate and a surface layer of the face plate made from flexible acoustic material on the face of the bottom plate; the surface layer is provided with an irregular surface. The vibrating diaphragm can be directly supported on the face plate via a folding ring in order to obtain favorable sound effects; the folding ring is fixed between the surface layer and the bottom plate of the face plate which is directly connected with the front pole plate. The high pitch loudspeaker adopting the structure can effectively reduce the interference of sound waves and the nonuniformity of frequency sound brought by the front cavity effect of the face plate, improving sound quality, and simultaneously, the production technology of the utility model is simplified.
Description
Technical field:
The utility model relates to a kind of sound-producing device that is used for sound system, specifically a kind of DYN dynamic high pitch loudspeaker.
Background technology:
Use high pitch loudspeaker more widely in the sound system at present, disclosed as No. 01217447.5, Chinese patent, mainly be made of vibrating diaphragm, vibrating diaphragm support, ring, preceding pole plate, voice coil loudspeaker voice coil, magnet, T iron and panel, magnet, preceding pole plate, vibrating diaphragm support, panel are socketed on the T iron in regular turn; On the vibrating diaphragm support, voice coil loudspeaker voice coil is connected on the vibrating diaphragm vibrating diaphragm by the ring suspension support, and before being suspended in the magnetic gap between pole plate and the T iron; Vibrating diaphragm generally all is designed to hemisphere; To increase its intensity.The panel of this high pitch loudspeaker generally adopts plastics or metal to process, this hard and flat panel, when speaker operation, be easy to generate sound wave interference and cause the frequency response characteristic of high pitch loudspeaker to worsen, tangible peak valley appears in frequency response characteristic, its harmonic distortion also obviously increases, and causes harmful effect for the tonequality of loud speaker.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency that existing its panel of high pitch loudspeaker is easy to generate sound wave interference, provides a kind of and has soft and the high pitch loudspeaker irregular surface panel, thereby obtain level and smooth frequency response characteristic and lower distorted characteristic.
For achieving the above object, the utility model high pitch loudspeaker comprises vibrating diaphragm, voice coil loudspeaker voice coil, preceding pole plate and panel, voice coil loudspeaker voice coil is connected on the vibrating diaphragm, and described panel comprises the panel top layer of being made by soft sound-absorbing material on base plate and the base plate face, and this top layer has irregular surface.
The irregular surface on described panel top layer comprises the rotary body of broken line shape or waveform; Can be between panel top layer and the base plate for bonding.
As further improvement of the utility model, described vibrating diaphragm directly can be supported on the panel by ring, this ring is fixed between panel top layer and the base plate; Described panel directly front pole plate connects, and the base plate of panel is provided with connecting hole and electric line portals.
The utility model compared with prior art, change existing hard and flat panel construction into utilized soft sound-absorbing material, had irregular surface panel construction, this panel has also played the vibrating diaphragm support simultaneously, reduced the frequency response unevenness that sound wave interference and panel " ante-chamber effect " bring effectively, improved tonequality, the production technology of high pitch loudspeaker also is simplified simultaneously.
Description of drawings:
Fig. 1 is the generalized section of known high pitch loudspeaker; Fig. 2 is the generalized section of the utility model high pitch loudspeaker.
Embodiment:
Below in conjunction with drawings and embodiments the utility model is further described:
As shown in Figure 2, the utility model comprises ball top shape vibrating diaphragm 1, ring 3, preceding pole plate 4, voice coil loudspeaker voice coil 5, annular magnet 6, T iron 7 and panel, described panel is composited by panel top layer 11 gluing the connecing of being made by soft sound-absorbing material on base plate 10 and the base plate face, this panel top layer 11 has irregular surface, described annular magnet 6, preceding pole plate 4, the panel that is composited by base plate 10 and soft top layer 11 is socketed on the T iron 7 in regular turn, this T iron comprises a pole region 12, this pole region 12 by 6 of annular magnets around, the preceding pole plate 4 that annular is arranged on the magnet, pole plate 4 before described, annular magnet 6 and T have annular magnetic gap 9 between the ferromagnetic polar region 12, have so just constituted a magnetic loop.In the magnetic gap 9 of voice coil loudspeaker voice coil 5 between preceding pole plate 4 and the ferromagnetic polar region 12 of T, the vibrating diaphragm 1 that is connected with voice coil loudspeaker voice coil 5 is positioned at the top of the ferromagnetic polar region 12 of T, this vibrating diaphragm 1 directly is supported on the panel by arc ring 3, this ring 3 is fixed between panel top layer 11 and the base plate 10, need not to re-use original vibrating diaphragm support, not only save material, simplify technology, the more important thing is, because vibrating diaphragm is directly to be supported on the panel, the position of the relative panel of vibrating diaphragm is than originally raising to some extent, so just can reduce the frequency response unevenness that panel " ante-chamber effect " brings effectively, further improve acoustical quality.
Described base plate 10 is provided with connecting hole 12,13 and electric line portals 14, and connecting hole 12 is to be used for loud speaker is fixed on audio amplifier, and 13 of connecting holes are used for the connection of panel front pole plate 4.Described panel top layer 11 can be made by the soft sound-absorbing material of porous, and the rotary body that its irregular surface can be broken line shape or waveform mixes; The base plate 10 integrated vibrating diaphragm supports of panel, it is that tweeters diaphragms installation bracing frame is connected support with electric outlet, is again the bearing support on panel top layer 11.In actual applications, according to the difference of the used material of high pitch loudspeaker vibrating diaphragm, shape, can correspondingly select different sound-absorbing materials and the suitable surface configuration of design, to reach optimum efficiency.By above this improvement, not only reduced the interference of sound wave effectively, improved tonequality, and the production technology of high pitch loudspeaker also is simplified.
