Abstract
一种厚度、体积极小的双声道扬声器。(如图一)其外部规格与普通卡式录音带相同，且以方便携带和收藏为其特征。
A dual-channel speaker with extremely small thickness and volume. (See Figure 1) Its external specifications are the same as those of an ordinary cassette tape, and it is easy to carry and store.
Description
The present invention relates to the structure of stereo cassette type speaker system, more specifically saying so refers to that a kind of volume is identical with common casette with outside specification, and can be placed on the three-dimensional two-way speaker in the cassette deck of carrying, listen to mini audio.
Because present the popular principle that mini music (general designation Walkman) is carried for convenience of listening to oneself, be not provided with sound-producing devices such as loud speaker, and only connect outside earphone (Earphone) or wear hair style earphone (Headphone) and come music appreciating via the accessory power outlet (outputjack) of Walkman.
According to inventor's research and with reference to the sound technique document: via earphone or when wearing the hair style earphone and listening to music, because earphone is close to ear, so sound wave that the earphone acoustical generator is sent, just directly reach ear drum membrane (Tympanum), the seismic wave of its general life simultaneously, just via skull (cramium) conduction and propagated sensation to the ear drum membrane of another side, this is said leap (crosstalk) or the phenomenon that is referred to as cross-talk, thereby produce the situation that phonotape and videotape (Image) concentrates on skull central authorities, generally be referred to as philharmonic society in the skull (Ochestra in the Cramiim).
As mentioned above, listen the hearer and just can't differentiate source of sound (Source) and position (position) or be referred to as the location sense, so just reduced fidelity factor.
More seriously, because ear drum membrane directly is subjected to the impact of sound wave, also can causes hard of hearing or lose and unfavorable condition such as listen.
Therefore, the inventor has just invented this stereo cassette type speaker system that is easy to carry, collects and meet health and appreciation enjoyment.
Design of the present invention is following finishing: the three-dimensional alliteration device of a kind of casette type, comprise by one by last, the casette flask body of the sealed composition of lower casing, one receives the latch of sound signal, one active member system and the magnetism circuit system that connects with lead-out wire with aforementioned latch, elements such as guard, wherein the active member system is made up of the oscillating plate that is the planar ultra-thin shape and one group of voice coil loudspeaker voice coil that links with binding agent, and be fixed in groove inner edge in the lid of aforementioned box body, the groove outer rim that is fixed in upper box cover with guard is protected described oscillating plate with cover again, the magnetism circuit system then is fixed on the iron oxide magnetite in the middle of both by one group of yoke that is provided with symmetrically and in order and central magnetic pole with epoxy resin and forms, and it is fixed in the groove of lid under the box body, therefore with the common three-dimensional loudspeaker arrangement that forms of described active member system, and entreat ad-hoc location among aforementioned latch central axis pin is fixed in upper box cover and lower casing openend, latch can be rotated receive to be stacked in the openend of box body.
In order more clearly to narrate the present invention, below embodiment is described, narration is carried out in conjunction with the accompanying drawings, wherein:
Fig. 1 is according to stereo cassette type speaker system oblique view of the invention process;
Fig. 2 is a loadspeaker structure exploded view shown in Figure 1;
As shown in Figure 1 and Figure 2, vibrator (200) adopts the design of plane formula, to reach ultra-thin purpose, utilizes binding agent to link voice coil loudspeaker voice coil (201,202), forms the active member system.The magnetism circuit system, system utilizes epoxy resin (Epoxr Resin) that iron oxide magnetite (Ferrite Magnet) (302,312) is fixed in the middle of both by the yoke (301,311) of soft iron punching out and center magnetic sheet (303,313), is fixed in the particular groove of lower casing (102) by binding agent again.
Completed active member system is fixed in the particular groove of upper box cover (101) with strength adhesive.Again with two lead-out wires and the voice coil loudspeaker voice coil (201 of dual track latch (40); 202) lead-out wire closes with soldering; and the central shaft of latch (40) is placed the ad-hoc location of upper box cover (101) and lower casing (102); with screw upper box cover (101) is combined with lower casing (102) again; at last guard (50) is fixed in the top of upper box cover (101) with strength adhesive, with protection vibrator (200).
Claims (1)
1, a kind of three-dimensional two-way speaker, the latch that comprises a reception sound signal, one active member system and the elements such as magnetism circuit system and guard that are connected with lead-out wire with aforementioned latch, it is characterized in that also comprising one by last, the casette flask body of the sealed composition of lower casing, and described active member system is made up of the oscillating plate that is the planar ultra-thin shape and one group of voice coil loudspeaker voice coil that links with binding agent, and be fixed in groove inner edge in the lid of aforementioned box body, the groove outer rim that is fixed in upper box cover with guard is protected described oscillating plate with cover again, the magnetism circuit system then is fixed in the iron oxide magnetite in the middle of both by one group of yoke that is provided with symmetrically and in order and central magnetic pole with epoxy resin and forms, and it is fixed in the groove of lid under the box body, therefore with the common three-dimensional loudspeaker arrangement that forms of aforementioned active member system, and entreat ad-hoc location among aforementioned latch central axis pin is fixed in upper box cover and lower casing openend, latch can be rotated receive to be stacked in the openend of box body.
