Abstract
The utility model relates to an improvement to the sound membrane of a loudspeaker, belonging to the vibrating membrane of the loudspeaker. The conntrol of the pronunciation working band of the prior loudspeaker is adjusted via electronic filter circuit; the prior loudspeaker has the disadvantages of high aberration and high cost price, and it's difficult to improve the sound quality of the loudspeaker beyond its limit. The technical method of the utility model is that the prior sound membrane body is equipped with filtering holes with various forms to form the sound membrane with the hole, known as the sound membrane equipped with an acoustic mechanical filter. The sound membrane with the hole has simple structure, easy manufacture, low cost, and it doesn't change the structure of the prior loudspeaker with easy use and less aberration for improving the sound quality of the loudspeaker obviously.
Description
Technical field
The utility model relates to the improvement of loud speaker middle pitch film, and especially Sound membrane with hole belongs to the vibrating membrane in the sound equipment.
Background technology
Mostly use traditional sound film in the existing loud speaker, the control of its pronunciation working band is to adjust with the electronic filter circuit that inductance capacitance is formed, and this electronic filter phase distortion is big, the cost height, and the tonequality that improves loud speaker is subjected to certain limitation.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, processing and fabricating is easy, cost is low, can improve the Sound membrane with hole of loud speaker tonequality.
The technical scheme that realizes the utility model purpose is: this Sound membrane with hole, constitute by sound film main body, and be characterized on the sound film, having at least one filtering hole.
Be equivalent on the sound film, be provided with the acoustics mechanical filter offering the filtering hole on the sound film.The parameters such as position in the shape in filtering hole, quantity, size and pitch-row, hole design definite according to the requirement of the different working band of sound film as calculated.The shape in filtering hole can be circle, square, triangle, ellipse, strip etc.
This Sound membrane with hole is simple in structure, processing and manufacturing is easy, need not change the basic structure of existing loud speaker, and is easy to install.Because this Sound membrane with hole processing cost is low, distortion is little, can reduce the cost of combination audio, obviously improves acoustical quality.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of embodiment of the utility model.Fig. 2 is that the utility model is installed in the user mode schematic diagram on the loud speaker.Among the figure: 1 sound film main body, 2 sound films, 3 rings, 4 film limits, 5 filtering holes, 6 panels, 7 terminal blocks, 8 sound film mounting brackets, 9 upper guide plates, 10 magnet steel, 11 magnetic conduction iron, 12 voice coil loudspeaker voice coils.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.With reference to Fig. 1, this Sound membrane with hole is to have at least one filtering hole 5 on the sound film main body 1 of existing various materials and size.Sound membrane with hole can be installed in easily on the existing various loud speaker and use, and its user mode is seen Fig. 2.
The utility model designer implements a kind of 1 inch Sound membrane with hole on the loud speaker that is installed in, the design of the part-frequency point of acoustics mechanical filter is at 3800 He Zhi on the sound film, offer 13 circular filter holes on the sound film, 0.8 millimeter of filtering bore dia, pitch-row has 4 millimeters and 9 millimeters two kinds, be installed on the loud speaker, descend with per minute shellfish octave negative 25 at part-frequency point through actual measurement.Audition part-frequency point place sound is clear, well arranged.The shape in filtering hole is also square, oval, strip or other shape.
Claims (2)
1, Sound membrane with hole is made of sound film main body, it is characterized in that having on the sound film at least one filtering hole.
2,, it is characterized in that the shape in described filtering hole can be circle, square, oval, strip according to the Sound membrane with hole of claim 1.
