Description
Technical field
The utility model relates to a kind of pronunciation device, more particularly, relates to the pronunciation device of a kind of headphone or audio amplifier.
Background technology
Headphone is a kind of equipment for listoning music on user Dai Yutou; it has the advantages such as sound field is good, comfort level good, protection duct compared to In-Ear Headphones; present young man, in order to follow the fashion and obtain better sense of hearing, also has more people to select to buy headphone.Audio amplifier, as the terminal of sound system, becomes requisite audio-frequence player device in Modern Family.For headphone and audio amplifier, the performance height of its inner pronunciation device is the key of whole headphone and audio amplifier voice quality.
The pronunciation component of existing headphone and audio amplifier is generally moving-coil or dynamic iron, moving-coil is as current most popular transducing pattern, the earphone of nearly 60% and almost all audio amplifier all adopt moving-coil to pronounce, the efficiency comparison of moving coil earphone and audio amplifier is high, and reliability and durability, but it needs more space and air to participate in vibration in the process of sounding, therefore effectively cannot control Lou sound phenomenon, wherein low frequency tonequality is better, and high frequency tonequality is just general; The soundproof effect of dynamic iron is better than moving-coil, and highly sensitive, and transient state performance is better, and good stability, volume is less, is common in In-Ear Headphones, but the voice output efficiency of single dynamic iron unit is lower, and adopt multiple dynamic iron unit, cost is higher again.Therefore, current headphone and audio amplifier are all with moving-coil unit for driven unit is to carry out the transmission of voice signal, and dynamic iron unit is mostly used in the relatively expensive In-Ear Headphones of price.But only using the voice effect of headphone that moving-coil unit is pronunciation component and audio amplifier unsatisfactory, pronunciation third dimension is strong, is difficult to satisfy the demands of consumers.
In order to solve the above-mentioned technical problem that prior art exists, applicant proposes invention and created name on September 10th, 2014: the technical scheme of the pronunciation component of a kind of headphone or audio amplifier, the patent No. of this patent application is: Zl201420518589.X, authorized announcement date is: on January 14th, 2015, this application case discloses the pronunciation component of a kind of headphone or audio amplifier, comprise support and moving-coil unit, also comprise dynamic iron unit, the rear side of described support is provided with moving-coil containing cavity, and described moving-coil unit is arranged in moving-coil containing cavity; The front side described support being positioned at moving-coil containing cavity is provided with dynamic iron containing cavity, and described dynamic iron unit is arranged at dynamic iron containing cavity; Described support is also provided with the moving-coil sender being communicated with moving-coil unit and the dynamic iron sender being communicated with dynamic iron unit.Moving-coil and dynamic iron unit organically combine by subject application, maximize favourable factors and minimize unfavourable ones, achieve the complementation of high and low audio frequency, effectively improve the tonequality of headphone and audio amplifier.But weak point is: the dynamic iron unit in this application case generally adopts horizontal placement, the sound of dynamic iron unit needs just can spread out of by once turning, and transmission sound route is long, easily causes sound loss; Further, limit by dynamic iron cellular installation mode, dynamic iron unit generally needs circumferentially to distribute.
