Description of the invention (p The present invention is a symmetrically deceived integrated speaker. It refers to a special type of speaker structure, that is, to form a magnetic field to form a vibration Membrane speakers * get the advantages of wide frequency response / low distortion Ο According to the structure of today ’s speakers, the “moving coil speakers” have the advantages of simple knotting, easy manufacturing, low price and good sound performance. , Which is the most commonly used speaker today. But these dynamic coil speakers are due to the limitations of their structural design. That is, they have several disadvantages. The following is explained one by one: ⑴ Distortion problem: due to the diaphragm of this speaker (Sound cone or paper cone) is indirectly connected to the voice coil located on the magnetic field of the permanent magnetic field. That is, the diaphragm is not located at the position where the magnetic field of the permanent magnet occurs, so * indirectly drives the diaphragm through the voice coil When performing reciprocating motion, a variety of distortion problems arise, but these distortion problems * can be changed by appropriately adjusting the material and resonance coefficient of the diaphragm itself , But only the method of treating the symptoms • and the effect of improving the degree of distortion is also very limited, only by fundamentally changing the basic structure of the Yang Qi can only be achieved. ⑵ the frequency is narrower: these moving coil type Yang He want to achieve high frequency When responding, you must use a thin, thin, and short diaphragm to provide the effect of high-frequency vibration. On the contrary, when you want to achieve low-frequency response, you must use a large-sized diaphragm to generate sufficient sound pressure and reproduce low sound quality. Therefore, • To achieve the sound reproduction effect of the full range • More than one speaker is required for the reproduction of bass, midrange or treble, which is the so-called multi-channel (two-channel, three-channel or more -3- paper) The scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) --------------- ^ ------ tT • (Please read the notes on the back before filling in This page) The A7 B7 is printed by the Beigong Consumer Cooperative of the Ministry of Economic Affairs of the Ministry of Economic Affairs. 5. Description of the invention (v) and more). However, in order to achieve a uniform frequency response in each sound range, it is necessary to add mold resistance / Capacitor / mildew and other passive components composed of Distinguish the various sound ranges • This move | not only makes the distortion more serious | and there is also the problem of mutual interference and phase distortion between the speakers * and the cost and complexity of the entire system also increase in phase • The best design is not the best 〇 Therefore, the speaker based on the aforementioned monolithic type cannot meet the requirements of the wide-range frequency loudspeaker effect and low distortion. The inventor thought to provide a new type of loudspeaker that can solve the above problems. The main purpose of the present invention It is to provide a symmetrical drive integrated hoist, which is mainly transmitted to the front / rear iron frame of the hoist through the magnetic field of the two poles of the permanent magnet, and forms N and S magnetic poles * respectively, and the front / rear iron frame is suspended between The diaphragm is coated with a thin layer of copper foil or aluminum foil on the surface. The cross-section of the diaphragm is folded into a shape where M and W are mutually derived, and the copper foil or aluminum foil loops of each fold The special design makes the whole diaphragm divided into a majority of positive and reverse flow directions. Therefore, it can make the diaphragm show symmetrical movement under the action of the signal circulation and the magnetic force lines of the front and rear iron frames. , By squeezing or expanding the folds to push the air to produce sound pressure. Under the above structure design, because the diaphragm is moved in a magnetic field, it can achieve the effect of direct movement, and its movement method is only to change the angle of each wrinkle symmetrically • instead of deformation. Wide frequency range and low distortion frequency response. In addition, each section of the diaphragm is actually independent-4-This paper scale is applicable to the Chinese National Standard (CNS) Α4 specification (210 X 297 mm), ^ Order " ( Please read the precautions on the back first and then fill out this page) 3061 ^ § a? _ B7 printed by the Beigong Consumer Cooperative of the Central Bureau of Economic Development of the Ministry of Economic Affairs 5. Micro-speaker of the invention description (》) • That is, the entire diaphragm E In the case of dozens to hundreds of folds, it can form a fixed air extruder. It also meets the requirements of high sound pressure. According to it, a speaker with a wide sound range and low distortion is formed. The second aspect of the present invention is to provide a symmetrically driven integrated speaker. These structures can be designed into a conical shape, a cylindrical shape, a flat plate shape, an ultra-thin shape or other forms, and can be formed in different sizes and sizes. Achieve the same effect, making it more flexible and versatile. Another object of the present invention is to provide a symmetrically deceived integrated hoist, a thin layer of copper foil or aluminum foil attached to the diaphragm. Although it functions as a voice coil, the voice coil of the present invention is They are formed on the corrugated edges of the wave type instead of the traditional coil shape. Therefore, the impedance is about a uniform resistance across the entire bandwidth range, so there is no coil at high frequency and low frequency. The impedance is different from the resonance phenomenon that generates resonance at low frequency and causes peak-to-peak impedance. Therefore, the present invention can improve the stability of the power amplifier and avoid the problem of overload of the amplifier. It also makes the design of the scorer particularly simple and convenient. Another aspect of the present invention is to provide a symmetrical dynamic integrated speaker. The voice coil of the present invention is distributed on a wide diaphragm to provide a good heat dissipation effect. • There is no heat accumulation and vulnerability of the coil coil type voice coil. Problem • Therefore, the speaker of the present invention can not be burned under the condition of large current flowing or instantaneous large current, and its wide-range frequency response feature can also solve each frequency of the conventional multi-channel loudspeaker system.

Description of the invention (y) The horizontally symmetric displacement of the zoom achieves the energy conversion effect of converting the mildew wave into the wave. As can be seen from the foregoing description, each group of diaphragm arrays mainly uses the coils of the main wrinkle part of the vertical section to produce a displacement effect, and the two sections of the vertical section are only for auxiliary use on both sides of the vertical section. The removal of the auxiliary wrinkle circuit on the side can also achieve the effect of lateral displacement *. After the addition of the auxiliary beryllium circuit, it has the effect of improving the conversion efficiency and improving the dynamic driving force. For the semi-cone-shaped hoist, as shown in the third and fourth gardens, the relevant structure of the combination is roughly the same. The only difference is that the permanent magnet (10) is only a large circle block Set it at the center position s · to form the same effect as the above-mentioned many small permanent magnets, and the sound-transmitting grid holes (21) and diaphragm (40) of the front and rear iron frames (20) (30) It is changed to a fan-shaped and ring-shaped arrangement. • The fourth circle's cross-sectional view provides better pointing characteristics and better sound scattering effects than a flat jack.
