Improved speaker structure (2)

A ribbon type speaker, in particular, which has an improved structure to reduce manufacturing cost and improve the quality of 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 first figure, the conventional ribbon speaker structure 10 includes a sound film 11 and magnets 12 and 13 integrated into one body via a combination frame R, wherein the sound film 11 is provided with a metal line 111. The magnet 12 and the magnet 13 are respectively disposed on the magnet holders 12A and 13A, and the magnet holders 12A and 13A are respectively located on both sides of the sound film 11. When the sound film 11 is energized, the current flowing through the metal line 111 and the magnets 12, 13 generate electromagnetic force, and the metal line 111 generates vibration to push the air to emit sound. Convert electrical energy into sound energy. The arrangement, density and material of the metal line 111 affect the resonance frequency of the vibration of the sound film 11, and further affect the sound that is emitted as a high-pitched sound with a high vibration frequency or a low-frequency middle sound.

A speaker structure 10 generates different treble or mid-range sound effects by adjusting the arrangement, density and material of the metal line 111, and then sets different speaker structures 10 in the same speaker, so that the same speaker can not only emit high-pitched sounds. A midrange can be produced to create a better and more varied sound effect.

Referring to the second figure, a speaker 2 is provided with a tweeter unit 21, a midrange unit 22 and a woofer unit 23, wherein the tweeter unit 21 and the middle unit 22 are each provided with a separate speaker structure 10.

Although the above-described embodiments of the prior art are taken as an example, it is conceivable that if more midrange or tweeters are added, more magnets, sound films, and larger speakers are required, and the manufacturing cost is therefore greatly increased. increase. In addition, since the positions of the midrange and the treble are separated by a certain distance, for example, listening to music in a large indoor space has no effect, but listening to music in a small indoor space, if the spatial distance is insufficient, the phase is easily offset and If the sound field is not easy to locate accurately, it can be clearly heard that the middle and high notes are emitted through different positions, so that the effect of the sound source like a real person can not be presented.

The purpose of the present invention is to provide a structure for improving the conventional ribbon speaker, which solves the problem that the conventional technology is expensive to manufacture, and also solves the disadvantage that the prior art cannot exhibit the sound source effect as if it were a live person singing.

The structure used in the creation to achieve the above purpose includes: a sound film; An intermediate sound film is disposed in the middle of the sound film via a partition structure; at least one first magnet is disposed in a first magnet holder, the magnet holder has at least one opening and an intermediate opening, the opening Arranging around the intermediate opening, the opening faces the sound film, the intermediate opening faces the intermediate sound film; at least one second magnet is disposed in a second magnet holder, and the sound film is disposed on the first magnet Between the bracket and the second magnet holder, the first magnet bracket and the second magnet bracket face different faces of the sound film.

Wherein, a speaker structure is disposed on a side of the second magnet holder relative to the sound film, and the speaker structure faces the second magnet holder. In a preferred embodiment, the speaker structure is shaped like a U-shape.

The sound emitting structure is disposed on a side of the first magnet holder relative to the sound film, and the sound emitting structure faces the first magnet holder. In a preferred embodiment, the sounding structure has an intermediate sounding unit and a plurality of sounding units, the sounding units are disposed around the intermediate sounding unit, the opening faces the sounding unit, and the intermediate opening faces the Intermediate sound unit.

In the illustration shown in the representative figure, the so-called "side" is the viewpoint of the representative figure, the left or right side of one of the objects inside; the so-called "between" is the viewpoint of the representative figure, and its setting position Between the two objects; the so-called "face", with the representative map as the viewpoint, with an imaginary line perpendicular or only intersecting the direction of any two objects.

The sound film and/or the intermediate sound film is an all-metal belt type sound film. Wherein, if the sound film and the intermediate sound film are all metal strip sound films, the structures of the two are different.

The sound film and/or the intermediate sound film is a substrate provided with a metal line. Wherein, if the sound film and the intermediate sound film are both one metal substrate, the metal lines are different.

The first magnet and/or the second magnet are at least one piece of magnet or at least one piece of magnet.

Through the above-mentioned arrangement and structure, since the intermediate sound film is disposed between the sound films, the conventional technology such as setting the two sound films requires more magnets and thus increases the cost, and the setting method makes it possible to make such a problem. The sound unit outputs the middle sound, which is sent around the high sound output from the middle sound effect unit, so that the overall sound effect is more stereoscopic, and the conventional technology conforms to 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.

The sound film or the composite soft substrate type sound film, or one is an all-metal belt type sound film and the other is a composite soft substrate type sound film.

Since the improved concept of the present invention uses a sound film to sound together around another sound film, the improved concept is used to make the sound films that generate different sound effects into a group, thereby reducing manufacturing costs and improving sound quality, and thus the sound film 3 And the intermediate sound film 5 is preferably a different sound film. 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. Preferably, the intermediate sound film 5 emits a high-pitched sound; the sound film 3 emits a middle sound, and therefore, if it is an all-metal belt type sound film, the wrinkle density of the forming is adjusted; for example, a composite soft substrate type The sound film needs to adjust the distribution of its metal lines so that the intermediate sound film 5 emits a high sound and the sound film 3 emits a middle sound. In addition, the sound film 3 and the intermediate sound film 5 may also be the same sound film, and are separated into two independent sounding regions by the partition structure 4.

The partition structure 4 is a wood or metal frame disposed between the sound film 3 and the intermediate sound film 5 in the embodiment shown in the third figure, and the purpose thereof is to effectively separate the soundproof film 3 and the intermediate sound film 5 from vibration.

In the embodiment, the first and second magnets 61 are provided. 71 is a strip magnet, and the first magnet holder 60 and the second magnet holder 70 are provided with a partition structure 4 in a "mouth" shape. In addition, the first magnet holder 60 is formed with at least one opening 62 and an intermediate opening 63. The opening 62 is disposed around the intermediate opening 63. When the first magnet holder 60 is disposed on the side of the sound film 3 The opening 62 faces the sound film 3; the intermediate opening 63 faces the intermediate sound film 5, so that the sound A emitted when the sound film 3 vibrates is transmitted from the opening 62; when the intermediate sound film 5 vibrates The sound B is transmitted from the middle opening 63.

It should be noted that although the two first and second magnets 61, 71 in the fourth figure are a group, this is not a limitation on the creation. Since the magnetic line of the magnet affects the vibration frequency of the sound film and the sound is emitted, the number, size, and arrangement of the first and second magnets 61 and 71 can be freely tested and adjusted by the user to perfectly match. A variety of different sound films produce the best sound. In addition, the first magnet 61 and/or the second magnet 71 may be at least one large piece of sheet magnet. When the magnets are sheet magnets, the brackets of the magnets may be wooden or other materials. .

In one embodiment shown in the fourth figure, the sound film 3 and the intermediate sound film 5 are composite soft. The substrate type sound film is an example. The sound film 3 is provided with a metal line 31 on an insulating substrate. The two ends of the metal line 31 are respectively connected with different electrodes and face the opening 62. The formed line and position are arranged such that the sound film 3 generates a middle sound when vibrating. Sound effects. The intermediate sound film 5 is provided with a metal line 51 on an insulating substrate. The two ends of the metal line 51 are respectively connected with different electrodes and face the intermediate opening 63. The formed line and position are arranged in such a manner that the intermediate sound film 5 vibrates when the middle sound film 5 vibrates. Sound effects. The two electrodes of the metal line 31 of the sound film 3 and the two electrodes of the metal line 51 of the intermediate sound film 5 may be connected separately or in parallel. In addition, the sound film 3 and the intermediate sound film 5 can also be middle or high sound sound films, thereby increasing the power of the overall output sound pressure.

The speaker structure 8 is preferably formed in a U-shaped shape and disposed on a side of the second magnet holder 70 with respect to the sound film 3, wherein the notch formed by the speaker structure 8 faces the surface of the second magnet holder 70. The material of the speaker structure 8 preferably uses a material that is less absorbing sound and can reflect sound, and the surface facing the second magnet holder 70 needs to pay attention to whether the surface has cracks to affect the sound reflection, and the surface can be matched with the sound film 3 and the middle sound. The position of the membrane 5 is adjusted to the structure, and the sound of the vibration of the two is modified. The size of the speaker structure 8 is smaller than that of the ordinary speaker, so that the creation can be reduced in size compared with the general speaker.

The sounding structure 9 is disposed on the side of the first magnet holder 60 with respect to the sound film 3, and the surface of the first magnet holder 60 is disposed with reference to the fifth drawing. Please refer to the fifth figure for a perspective view of the speaker prepared by using this creation.
