Description
Technical field
The utility model relates to loud speaker, relates in particular to a kind of dynamic speaker.Belong to the electroacoustic techniques field.
Background technology
Dynamic speaker in the loud speaker has obtained using widely in sound equipment, television set etc. owing to have simple in structure, advantages such as bass is plentiful, tonequality is soft, bandwidth.
Number be 881063479 at Chinese patent, open day for March 28 nineteen ninety day, be called in the patent documentation of " loud speaker " and disclose a kind of dynamic speaker.Dynamic speaker in this patent documentation comprises electromagnetic circuit system, voice coil loudspeaker voice coil, vibrating diaphragm and framework.The tapered structure of sound basin that wherein has vibrating diaphragm and framework to constitute.
The sound basin of prior electric formula loud speaker all is a pyramidal structure all as the sound basin in the above-mentioned patent, so sound basin thickness is thicker, the thicker integral thickness of loud speaker that caused of the thickness of sound basin is thicker.And along with television set to ultra-thin plate development, make that especially thickness space is very little for the space of housing of TV set, develops towards slimming so the dynamic speaker of existing structure can not adapt to and restrict television set.Seek the little electrodynamic loudspeaker of a kind of thickness and also become most television manufacturers in the thing of making great efforts to solve.
The utility model content
The utility model provides a kind of dynamic speaker of thin thickness, has solved prior electric formula loud speaker and can not adapt to and restrict the problem of television set towards the slimming development owing to what the sound basin is designed to pyramidal structure causes.
Above technical problem solves through following technical proposal: a kind of dynamic speaker; Comprise sound basin, voice coil loudspeaker voice coil and magnet; The sound basin comprises vibrating diaphragm and basin frame, and said vibrating diaphragm comprises the vibrating diaphragm trunk and the vibrating diaphragm ring of slab construction, said basin frame comprise the tabular basin frame body that parallels with vibrating diaphragm be arranged on the basin frame body outer rim annular flange; Said voice coil loudspeaker voice coil one end is fixed together with said vibrating diaphragm, and said vibrating diaphragm trunk is connected on the free end of said flange through said vibrating diaphragm ring.This kind structural design to the sound basin makes the sound basin be a flat box body structure; Can reduce the whole height of dynamic speaker; Make dynamic speaker can adapt to the article of thinner thickness such as the use needs of television set, thereby can not restrict the slimming development of television set.
As preferably, the outer surface of said vibrating diaphragm ring is provided with the vibrating diaphragm ring portion cannelure that circumferentially extends along the vibrating diaphragm ring that is formed by vibrating diaphragm ring inwardly protruding.Design vibrating diaphragm ring portion cannelure; Can improve the vibrating diaphragm trunk with the bonding strength between the basin frame; And vibrating diaphragm ring portion cannelure to be vibrating diaphragm ring inwardly protruding form, then the design of ring is little and can not cause the increase of the gauge of sound basin to the deadweight influence of vibrating diaphragm ring.
As preferably, the inner surface of said basin frame body is provided with the basin frame portion cannelure that the same vibrating diaphragm ring portion cannelure that formed to outer lug by the basin frame body aligns.Basin frame portion cannelure is set plays with the distance between the basin frame body hour, when also being the thinner thickness of loud speaker, can not producing collision and cause distortion in the vibrating diaphragm vibrating diaphragm process with the basin frame body at the vibrating diaphragm trunk.Help further dwindling of basin frame thickness.
As preferably, the center of said vibrating diaphragm trunk is provided with the boss that is formed towards outer process by the vibrating diaphragm trunk, and said voice coil loudspeaker voice coil is positioned at the dead astern of said boss and is covered fully by said boss.Can promote the effective stroke of dynamic speaker; Increase vibrating diaphragm trunk intensity; Reduce resonance frequency.
The root of said boss is provided with the outwards annular link slot of depression of the outside convex inner surface of inner surface, and boss links together with the vibrating diaphragm trunk through said link slot.Improve protruding with the bonding strength between the vibrating diaphragm trunk.
The utility model comprises that also input audio signal gives two of voice coil loudspeaker voice coil to go between and be located in the back cover on the basin frame body; Said magnet is positioned at the inner that back cover outer end, the said voice coil loudspeaker voice coil other end are located in back cover, and the inner face of said back cover is provided with two lead-in wire protective troughs.In the process that lead wire vibrates in company with the ictus film together, if when amplitude is big, the lead-in wire protective trough plays and prevents that lead wire or lead-in wire from colliding with the back cover internal end surface with the junction of vibrating diaphragm trunk and cause short circuit or different sound.If connect with lead-in wire after making the end of a thread of voice coil loudspeaker voice coil stride across back cover, then the end of a thread of voice coil loudspeaker voice coil is equal to lead-in wire.
As preferably, said lead-in wire links together with said vibrating diaphragm trunk.Improve lead-in wire with the bonding strength between the voice coil loudspeaker voice coil, lead-in wire is not easy to produce disengagement or poor electric contact phenomenon with voice coil loudspeaker voice coil in the vibration processes.
As preferably, said magnet is neodymium iron boron.Magnetic stability can improve the tonequality of loud speaker.
The utlity model has following advantage,, can reduce the thickness of sound basin, make that the gauge of dynamic speaker is thin through with vibrating diaphragm with the basin frame body is designed to slab construction and voice coil loudspeaker voice coil directly is connected on the vibrating diaphragm.Further reduce the thickness of sound basin in the preferred version, made the dwindling of gauge of loud speaker reach optimum.
