Description

Method and structure for improving speaker

A method and structure for improving a ribbon speaker, which reduces the manufacturing cost of the ribbon speaker and improves the quality of the output music.

The ribbon type speaker is a kind of sound film and voice coil speaker which replaces the traditional moving coil type speaker with a belt-shaped sound film, and is formed into a strip-shaped sound film between two magnets, and uses electromagnetic induction as a sound film. When the current is passed, the sound film vibrates and makes a sound.

Ribbon-type speakers are not a brand-new technology. There are various types of ribbon speakers on the market. Among them, the sound film can be divided into all-metal belt sound film and composite soft substrate type sound film. As the name implies, the all-metal belt type sound film is formed by metal forming, generally using aluminum; the composite soft substrate type sound film utilizes an insulating substrate, and a metal line is disposed on the substrate.

The conventionally known ribbon speaker structure will be described below by way of illustration.

Referring to the fifth figure, the conventional ribbon speaker structure U includes a sound film U1 and magnets U2 and U3, which are integrated into one body via a combination frame R, wherein the sound film U1 is provided with a metal line W. The magnets U2 and U3 are respectively disposed on the magnet holders U21 and U31, and the magnet holders U21 and U31 are respectively located on both sides of the sound film U1. When the sound film U1 is energized, the current flowing through the metal line W and the magnets U2, U3 generate electromagnetic force, and the metal line W generates vibration to push the air to emit sound. Convert electrical energy into sound energy. Among them, the arrangement mode, density and material of the metal line W affect the resonance frequency of the vibration of the sound film U1, and then the sound that is emitted is a high-pitched sound or a slow-sounding middle sound.

A speaker structure U can generate different high-pitched or mid-range sound effects by adjusting the arrangement and density of the metal lines W, and then set different speaker structures in the same speaker, so that the same speaker can not only emit high-pitched sounds. A midrange is produced to create a better and more varied sound effect.

However, if more speaker structures are added to the same speaker, more magnets, sound films, and larger speakers are required, and the manufacturing cost is greatly increased. In addition, because the positions of different speaker structures are separated by a certain distance, such as listening to music in a large indoor space, there is no influence, but listening to music in a small indoor space can be clearly heard if the spatial distance is insufficient. The treble is sent through different positions, so that it is impossible to present the effect of the sound source that is like a real person singing.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for improving a conventional ribbon speaker, which solves the problem that the prior art is expensive to manufacture, and also solves the disadvantage that the prior art does not exhibit the effect of sound source as if it were a live person.

Wherein, the speaker structure is matched with the sounding structure, so that the second sound effect is outputted from the periphery of the first sound effect output. If so, the second sound effect can be output to surround the sound of the first sound effect, thereby causing the structure output using the method of the present invention to output the sound source effect of a real person.

Wherein, the vibration frequency of the first sound film is preferably higher than the vibration frequency of the second sound film, such that the first sound film emits a sound effect higher than the second sound film, that is, the second sound film emits a sound effect of the middle sound; A sound film emits a high-pitched sound.

In addition, the present invention also includes a structure for implementing the above method, the structure comprising: a first sound film which emits a first sound effect when vibrating; and a second sound film which emits a second sound effect when vibrating; at least one The common magnet is disposed in a common magnet holder, the common magnet holder is located between the first sound film and the second sound film; at least one first magnet is disposed in a first magnet holder, the first magnet holder Having at least one first opening, the first magnet holder is disposed on a side of the first sound film such that the first sound film is interposed between the common magnet and the first magnet holder, the first opening The hole faces the first sound film such that the first sound effect passes through the first opening; the at least one second magnet is disposed in a second magnet holder, and the second magnet holder has at least one second opening, a second magnet holder is disposed on a side of the second sound film such that the second sound film is interposed between the common magnet and the second magnet holder, and the second opening faces the second sound film, such that The second sound effect passes through the second opening; a speaker The second magnet holder is disposed on a side of the second magnet holder opposite to the second sound film, the speaker structure faces the second magnet holder, and the second sound effect is reflected by the speaker structure through the second opening; and The sounding structure has a first sounding unit and a plurality of second sounding units, the sounding structure is disposed on a side of the first magnet holder relative to the first sound film, and the first sounding unit faces the first opening Hole, making the first sound effect After the first opening is output through the first sound effect unit, the second sound effect is reflected by the sound box structure and output through the second sound effect unit.

Among them, the so-called "side" is the viewpoint of the third figure, the left or right side of one of the objects inside; the so-called "between" is the viewpoint of the third figure, and its setting position is between the two objects. The middle; the so-called "face", with the third picture as the viewpoint, with an imaginary line perpendicular or only intersecting the direction of any two objects.

Among them, the structure of the speaker is shaped like a ㄇ shape, which can achieve better modification and reflect more sounds. The speaker structure is used to assist in modifying and reflecting the middle sound generated by the vibration of the second sound film.

The second sound effect unit is disposed around the first sound effect unit.

The first sound film and/or the second sound film is an all-metal belt type sound film, wherein if the first sound film and the second sound film are all metal tape sound films, the structures are different.

Through the above structure, since the two sound films share a set of magnets, the prior art, such as setting a two-tone film, requires more magnets and increases the cost. The second sound effect unit is disposed around the first sound effect unit through the reflection and modification of the speaker structure, so that the second sound effect unit outputs a middle sound, which is outputted around the first sound effect unit. The high-pitched sound makes the overall sound more stereoscopic, and the more familiar technology is in line with the effect of the sound source of the real person singing. In addition, by reducing the number of magnets, the amount of space required to be placed in the speaker is also indirectly reduced, thereby reducing the overall volume, and a smaller speaker can be manufactured than conventional techniques.

Since the improved concept of the present invention shares two sets of magnets with two different sound films, thereby saving manufacturing costs, and using this method to make sound films that produce different sound effects into a group, thereby improving sound quality, the first sound is improved. The film 1 and the second sound film 2 are preferably different sound films. Among them, the so-called different sound films can be made of an all-metal tape type sound film and a composite soft base type sound film, or both of them are all-metal tape type sound films, but the formed materials and structures are different. Or both are composite soft substrate type sound films, but the metal wiring and position on the substrate are different. In a preferred embodiment, the first sound film 1 has a higher vibration frequency than the second sound film 2, that is, the first sound effect A is a high sound, and the second sound effect B is a middle sound.
