Referring to the speaker design, the main method used in the past is to design the speaker based on the experience of the speaker. At present, Computer Aided Design (CAD, Computer Aided Design) is widely used, and various speakers (speakers) are designed for speakers of speakers. In fact there is a matching design method, because the speaker (speaker) parts of species and varieties, specifications and diverse, the designer according to the requirements of the user selected appropriately, adjust, shorter time to meet user requirements, also can yet be regarded as a particular method.

Whether using traditional methods or the CAD or matching method is adopted to speaker (speaker) design, design needs to be selected, the design method is to a certain design under the guidance of the thought. So there are pros and cons.

The design of the speaker (speaker) depends on the requirement of the speaker (speaker), which is used and used. It is embodied in some technical indicators and requirements. These requirements are many, and for the sake of convenience, we can sum it up to the following 10 items:

(1) playback frequency and frequency characteristics of speakers (speakers);

(2) speaker (loudspeaker);

(3) distortion of speaker (speaker);

(4) the power and dynamic range of the speaker (speaker);

(5) impedance and impedance characteristics of speakers (speakers);

(6) resonant frequency, quality factor and equivalent volume of loudspeaker (horn);

(7) the sensitivity and efficiency of the speaker (speaker);

(8) the appearance, life and applicability of speakers (speakers);

(9) speaker (loudspeaker) sound quality and sound orientation;

(10) other special requirements for loudspeakers (speakers).

Ten requirements for speaker (speaker) is put forward in 1984, 20 years later, a slight change and increase the 10 items, especially to increase the sound character of the speaker (speaker) and sound orientation ", suggests that advances our understanding of the speaker (speaker).

According to the above 10 requirements, the speaker design process should identify and solve the following 10 problems:

(1) type of speaker (speaker);

(2) loudspeaker (speaker) diameter, effective radiation area and height;

(3) diameter, material and winding number of loudspeaker (speaker);

(4) geometric shape of speaker (speaker) diaphragm;

(5) the elastic modulus, density and inner damping of the diaphragm of the speaker (speaker);

(6) the structure and nature of the magnetic circuit of the speaker (speaker);

(7) material and shape of diaphragm folding loop;

(8) speaker (speaker) structure and selection of other components;

(9) guarantee of speaker (loudspeaker) sound quality;

(10) speaker (loudspeaker) process selection, production management, quality assurance.

Speaker (speaker) of theory and practice have proved that to meet the requirement on the properties of the speaker (speaker) must carry out the corresponding design and select the corresponding process, but a sense of each other echo, between these requirements and restrain each other and even contradictory. At the same time, there is also the relationship between the ten problems that design and process should be solved.
