Abstract

An improved speaker structure includes a basin stand, a hanging edge and a vibrating membrane. The vibrating membrane has a circumference sealed on the edge of an opening of the basin stand, and an accommodation area is arranged inside the opening of the basin stand. The hanging edge is arranged between the vibrating membrane and the accommodation area of the basin stand. Therefore, when the voice current signals are applied into a voice coil inside the basin stand, the voice coil outputs the audio signals and further drives the vibrating membrane to vibrate so as to generate the sound. With the design of the hanging edge, the present invention is able to make the vibrating membrane vibrate up and down more smoothly so as to reduce the distortion rate, thereby allowing the vibration to have less resistance in comparison with the prior structure.

[Prior Art] The principle of the action of the speaker is based on the left-hand rule of Fleming. The voice coil (v〇iee Coil) in the current is placed in the magnetic field. 'Because of the force generated by the motion, the diaphragm is driven to push the air to make a sound. An electroacoustic device that converts an electrical signal into a mechanical energy that pushes air to emit a sound; specifically, the operation of the speaker actually converts a range of audio electric power signals into a small distortion and has sufficient sound pressure through a transducing mode. Acoustic sound; the commonly used speaker is a moving coil speaker, and the moving coil speaker is composed of a magnetic circuit module (permanent magnet, core column, magnetic conductive plate), vibration module (paper cone, voice coil) ) and supporting auxiliary modules (centering brackets, basin brackets, rims) and other three parts, wherein the voice coil is directly fixed to the diaphragm, and when the sound current signal is transmitted to the voice coil, it is in a permanent magnetic field. The entangled cylindrical coil is connected to the diaphragm, and the coil is driven by the signal current, the voice coil vibrates, and the diaphragm is driven to generate vibration, thereby generating sound; The difference between a speaker and a general speaker is the difference in the diaphragm. The diaphragm edge of the speaker is usually fixed on the elastic medium (folding ring and centering piece) (for example, on a large-diameter bass unit), and the diaphragm is generally flat. The conical shape, the vibration of the vibration system is provided by the elastic medium. As shown in Fig. 1A and Fig. 1B, in the moving coil type speaker, the edge of the diaphragm is directly fixed on the frame of the driving unit, and the diaphragm 1 has a hanging suspension. Side 2, the vibration system is completely provided by the extension of the diaphragm 丨5 201023660 and the contraction and the deformation of the suspension 2, so the material selection and shape design of the diaphragm of the moving coil drive unit is the final sound of the unit. The quality influence is very large. Therefore, when the suspension 2 on the diaphragm 1 vibrates up and down, part of the vibration will be canceled by the wrinkles, and the complete sound cannot be emitted, resulting in a distortion rate. It can be seen that the above-mentioned conventional and current methods are not a good design and need to be improved. In the case of the inventor of the present invention, the shortcomings derived from the above-mentioned conventional methods were improved and innovated by the thoughts, and after years of hard work and research, finally successfully developed the improved structure of the speaker. SUMMARY OF THE INVENTION An object of the present invention is to provide an improved speaker structure which can provide a vibration-adding surface and a distortion rate when the voice coil generates vibration, and which is less resistant than conventional structures.达成 Achieving the above-mentioned object of the invention - a sound-improving structure consisting of a basin-and-vibration module; the towel is spliced by a combination of holes, and the vibration module comprises a hanging edge and - a diaphragm 'in which the periphery of the diaphragm is sealed at the edge of the basin, and a accommodating area is disposed at an inner side of the opening of the basin, and the hanging edge is vertically connected between the diaphragm and the cradle receiving area Therefore, when the sound current signal passes through the sound inside the basin, the voice coil vibrates and drives the diaphragm to generate vibration. _ Sounds. When riding the voice coil to generate the crane, the diaphragm can be vibrated up and down more smoothly by (4). And reduce the distortion rate, so that the vibration is more resistant than the transmission. 201023660 *' [Embodiment] Please refer to FIG. 2A, FIG. 2B and FIG. 2C for a partially exploded view, a perspective view and a cross-sectional view of a modified speaker structure according to the present invention. As can be seen from the figure, the speaker unit 3 includes at least a basin frame 4, an accommodating area 41 is disposed at an inner side of the opening of the basin frame 4, and the accommodating area 41 is an L-shaped annular space which is recessed inwardly, and the accommodating area 41 has a resistance a portion 411; a suspension 51, the suspension 51-end is fixed to the periphery of the diaphragm 52 and the other end is fixed on the basin abutting portion 411; 0 a vibrating 52, wherein the diaphragm 52 After the peripheral edge is adhered to the hanging edge 51, it will be sealed at the edge of the opening of the basin frame 4. When the sound current signal passes into the voice coil inside the basin frame 4, the voice coil vibrates and drives the diaphragm 52 to generate vibration. The sound is emitted, and when the voice coil vibrates, the vibration of the diaphragm 52 can be made smoother and the distortion rate can be reduced by the suspension μ, so that the vibration is less resistant than the conventional structure. Referring to FIG. 2 in June, a cross-sectional view of an embodiment of the improved speaker structure of the present invention is used. The present invention adopts a sound circle «, when the voice coil is input, an audio current is charged, and the sound is _# in a carrier-loaded beta current conductor. If you put it in a fixed magnetic field, according to the principle that the conductor is moving under the action of the magnetic force, the voice coil will be subjected to a force whose magnitude is proportional to the audio current and the direction changes with the audio current; The voice coil will vibrate in the magnetic field, and drive the diaphragm _ and vibrate 'and the air before and after the diaphragm will also vibrate, thus converting the electrical signal into sound waves to radiate around; as shown in Figure 3, when the sound When the ring generates vibration, the diaphragm can be vibrated up and down by the hanging edge, and an up and down vibration degree R is generated. Compared with the conventional speaker in Fig. 1c, when the voice coil 7 201023660 vibrates, the hanging edge The diaphragm is vibrated up and down, and the suspension is disposed on the plane on the left and right sides of the diaphragm. Therefore, the vibration amplitude is - angle θ, and the degree of vibration is greatly limited, and the diaphragm is vibrated up and down. Have resistance, resulting in no The method emits a complete sound, resulting in the generation of a distortion rate. In addition, the present invention limits the size of the basin to obtain the maximum effective vibration area (Sd) to maximize the sound pressure efficiency, and the actual calculation formula is: 355 X (five) 2 V =_v ^ ^
