Abstract
The utility model discloses an electrodynamic loudspeaker. The loudspeaker comprises a basin stand, a terminal board on the basin stand, a washer, a positioning support chip and an iron core. The basin stand is equipped with a drum paper with a braided wire. A bullet type aluminum phaser is arranged in front of the drum paper. The washer is assembled together with the terminal board on the basin stand. By using the electrodynamic loudspeaker provided in the utility model, because the dia-cutting aluminum phaser is arranged in front of the drum paper, an unfavorable air pressure eddy current generated by up-and-down motion changes a direction, which can be compared to adding an airflow lubricant. Drum paper sound wave transmissibility is fully used. An extension of a high frequency scope is increased and losses are reduced. A dynamic scope is improved and a distortion is reduced. An appearance of the loudspeaker is novel and unique and the loudspeaker is an ideal multipurpose electrodynamic loudspeaker.
Description
Technical field
The utility model relates to the loudspeaker techniques field, relates in particular to a kind of dynamic speaker that increases the high frequency response scope.
Background technology
Dynamic speaker is called again coil-moving speaker, and it is according to the electroacoustic principle, and electric energy is converted to a kind of transducer of acoustic energy, it be use at most, loud speaker the most widely.
Common speaker operation principle is electromagnetic induction, voice coil loudspeaker voice coil in being in magnetic field have tone currents by the time can produce with the tone currents changing magnetic field, the magnetic field of this magnetic field and permanent magnet interacts, make voice coil loudspeaker voice coil along axial vibration, and then drive the vibration of drum paper and cause air vibration, thereby cause acoustic irradiation.Extension, loss that this loud speaker can not get high-frequency range are large.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model provides a kind of dynamic speaker.
The purpose of this utility model realizes by following technical scheme:
Dynamic speaker comprises: terminal block, washer, locating branch slice and iron core on basin frame, the basin frame, and described
Be equipped with the bulging paper with litzendraht wire on the basin frame;
The place ahead of drum paper is provided with bullet-type aluminium matter phaser;
Terminal block on washer and the basin frame fits together.
Compared with prior art, one or more embodiment of the present utility model can have following advantage:
The dynamic speaker that the utility model provides, owing to add the aluminium matter phaser of a dia-cutting in the place ahead of drum paper, produce disadvantageous air pressure eddy current change direction thereby can make moves up and down, caing be compared to increases an air-flow lubricant, take full advantage of bulging paper Acoustic Wave Propagation, both increased the extension of high-frequency range, reduced again loss, both improve dynamic range, reduced again distortion.
The loud speaker outward appearance is novel unique, is a comparatively ideal Multipurpose electric dynamic formula loud speaker.
Other features and advantages of the utility model will be set forth in the following description, and, partly from specification, become apparent, perhaps understand by implementing the utility model.The purpose of this utility model and other advantages can realize and obtain by specifically noted structure in specification, claims and accompanying drawing.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and consists of the part of specification, jointly is used for explaining the present invention with embodiment of the present utility model, does not consist of restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the dynamic speaker structural representation;
Fig. 2 is the dynamic speaker cross-sectional view.
Embodiment
Understand easily, according to the technical solution of the utility model, do not changing under the connotation of the present utility model, one of ordinary skill in the art can propose a plurality of frame mode of the present utility model and manufacture method.Therefore following embodiment and accompanying drawing only are specifying of the technical solution of the utility model, and should not be considered as of the present utility model all or be considered as restriction or the restriction of technical solutions of the utility model.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
Shown in Figure 1 is structural representation according to the dynamic speaker of the utility model embodiment, below with reference to Fig. 1, describes the various piece of the utility model embodiment and the function of various piece in detail.
As depicted in figs. 1 and 2, structure and cross-section structure for dynamic speaker of the present utility model comprise: the terminal block 2 on basin frame 1, the basin frame 1, washer 3, locating branch slice 4 and iron core 5, and described
Be equipped with the bulging paper 7 with litzendraht wire 6 on the basin frame;
The place ahead of drum paper is provided with bullet-type aluminium matter phaser 8;
Terminal block on washer and the basin frame fits together.
Above-mentioned loud speaker also comprises magnet steel 9 and the voice coil loudspeaker voice coil 10 that basin frame bottom arranges, and described voice coil loudspeaker voice coil and bullet-type aluminium matter phaser are fixed.
The outer setting of above-mentioned bullet-type aluminium matter phaser has case ring 11.
The edge of above-mentioned bulging paper is provided with pad limit 12.
Bulging paper on above-mentioned basin frame, the basin frame reaches the litzendraht wire of pasting with drum paper and is the handstand splayed.
Above-mentioned bullet-type aluminium matter phaser is the aluminium matter phaser of a dia-cutting, and making moves up and down produces disadvantageous air pressure eddy current change direction, and caing be compared to has increased an air-flow lubricant, both increased the extension of high-frequency range, reduce again loss, both improved dynamic range, reduced again distortion.
Present embodiment is analyzed drum paper Acoustic Wave Propagation Characteristics according to the electroacoustic principle of electrodynamic loudspeaker, takes full advantage of bulging paper bottom area, has increased the extension of high-frequency range.
Although the disclosed execution mode of the utility model as above, the execution mode that described content just adopts for the ease of understanding the utility model is not to limit the utility model.Technical staff under any the utility model in the technical field; under the prerequisite that does not break away from the disclosed spirit and scope of the utility model; can do any modification and variation in the details that reaches of implementing in form; but scope of patent protection of the present utility model still must be as the criterion with the scope that appending claims was defined.
