Abstract
The utility model provides a double-coil for mobile communication, having a construction of loudspeaker, and a construction of vibrator on the other side. The vibrator and the loudspeaker are integrated into one, so that space is saved. The utility model uses the same signal for driving, so that difficulty of designing and manufacturing main board of signal source is reduce, cost is lowered. The magnetic construction design can improve bass sound quality of the loudspeaker system in the mean time.
Description
Technical field
The utility model belongs to other sound one dynamo-electric sensing group in International Patent Classification (IPC), i.e. H04R, the particularly electromagnetic shaker used of mobile communication terminal, device, the parts of loud speaker unification.
Background technology
Mobile communication terminal is mobile phone, Personal Handyphone System, cordless telephone etc., and none does not possess microphone device as call reminding in it.Usually adopt coil-moving speaker.It is made up of parts such as magnet steel, voice coil loudspeaker voice coil, sound films, comprises two kinds of internal magnetization and external magnetic types.This loud speaker is owing to volume and Power Limitation, and its frequency range is narrower, and low segment tonequality feels relatively poor.Another kind of call reminding adopts vibration mode, often produces vibrations with eccentric motor.This moment, electromagnetic shaker and loud speaker were divided into two parts, needed two different drive signals.
The utility model content
The purpose of this utility model is to provide a kind of mobile communication with double-tone circle, dual-magnetic-field vibration loudspeaker, and it is with electromagnetic shaker and the synthetic parts of loud speaker, with same drive.
It is as follows to disclose new technical scheme:
A kind of mobile communication has at least parts such as base, magnet steel, voice coil loudspeaker voice coil, magnetic cover, latch plate, clamping plate, sound film and terminal block and lead-in wire thereof to form with double-tone circle, dual-magnetic-field vibration loudspeaker:
Described magnet steel, clamping plate, magnetic cover coaxial line are fixed on the latch plate, and the edge of latch plate is fixed on the base inner wall shoulder with one heart;
The below of magnetic cover, coaxial line are fixed with by the marmon clamp plate holder to live and fixing annular magnetic steel, and the periphery of annular clamping plate is fixed with quality loop;
Be fixed in the vibrations coil of base end face, coaxial line is positioned among the magnetic circuit of annular magnetic steel and magnetic cover formation.
By the sample of this scheme trial-production, the space has been saved in electromagnetic shaker, both unifications of loud speaker.As driving, reduce design, the manufacture difficulty of signal source mainboard with same signal, reduced cost.The magnetic structure of this design, the while can be improved the low segment tonequality of speaker system.
Description of drawings
Figure is the cross-sectional schematic of an embodiment of the utility model.Wherein: 1, terminal block 2, cover 3, sound film 4, clamping plate 5, magnet steel 6, voice coil loudspeaker voice coil 7, magnetic cover 8, latch plate 9, lead-in wire 10, base 11, quality loop 12, annular clamping plate 13, vibrations coil 14, annular magnetic steel.
Embodiment
A kind of mobile communication is with double-tone circle, dual-magnetic-field vibration loudspeaker, has base 10, magnet steel 5, voice coil loudspeaker voice coil 6, magnetic cover 7, latch plate 8, clamping plate 4, sound film 3 at least and goes between 9 and terminal block 1, it is characterized in that:
Described magnet steel 5, clamping plate 4, magnetic cover 7 coaxial lines are fixed on the latch plate 8, and the edge of latch plate 8 is fixed on the base 10 inwall shoulders with one heart;
The below of magnetic cover 7, coaxial line are fixed with by annular clamping plate 12 and clamp and fixing annular magnetic steel 14, and the periphery of annular clamping plate 12 is fixed with quality loop 11;
Be fixed in the vibrations coil 13 of base 10 bottom surfaces, coaxial line is positioned among the magnetic circuit of annular magnetic steel 14 and magnetic cover 7 formations.
Terminal block 1 has contact, is connected with the head and tail of voice coil loudspeaker voice coil 6, vibrations coil 13 leads respectively and goes between 9.
According to interior magnetic, two kinds of structures of outer magnetic speaker, above-mentioned loud speaker and electromagnetic shaker structure can be exchanged, do not move but note shaking coil 13, the magnetic circuit that clamping plate 4, magnet steel 5, magnetic cover 7, quality loop 11, annular clamping plate 12, annular magnetic steel 14 are formed can move with the active force that vibrations coil 13 or voice coil loudspeaker voice coil 6 are produced.This structure is exchanged concerning the professional and technical personnel, needn't elaborate.
