Improved speaker structure (1)

A ribbon type speaker, particularly comprising an improved structure, which reduces manufacturing costs and improves 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 resonant frequency of the vibration of the sound film 11, and thus the sound that is emitted is a high-pitched sound or a slow-moving midrange.

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 first tweeter unit 21, a second tweeter unit 22 and a midrange unit 23, wherein the first and second tweeter units 21, 22 and the middle unit 23 are provided internally. Independent speaker structure 10. Therefore, as described above, the same speaker 2 allows the user to listen to music with a wide sound field and uniform sound quality.

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, because the positions of the midrange and treble 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 obviously be heard if the spatial distance is insufficient. The middle and high notes are sent 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 by the creation to achieve the above purpose includes: a first sound a second sound film; at least one common magnet disposed between the first sound film and the second sound film; at least one first magnet 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 Facing the first sound film; and at least one second magnet disposed in a second magnet holder, the second magnet holder having at least one second opening, the second magnet holder being disposed on a side of the second sound film The second sound film is interposed between the common magnet and the second magnet holder, and the second opening faces the second sound film.

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

Wherein, a speaker structure is disposed on a side of the second magnet holder relative to the second sound film, and the speaker structure faces the second magnet holder to assist in modifying and reflecting the middle sound emitted by the vibration of the second sound film. In addition, the structure of the speaker is shaped like a ㄇ shape, which can achieve better modification and reflect more sound.

The sound emitting structure is disposed on a side of the first magnet holder relative to the first sound film, and the sound emitting structure faces the first magnet holder. The sounding structure has a first sounding unit and a plurality of second sounding units, the second sounding unit is disposed around the first sounding unit, and the first opening faces the first sounding unit. The first sound effect unit can output sound generated by vibration of the first sound film transmitted from the first magnet holder disposed on the side of the sounding structure, and the second sound effect unit can output the second sound film to transmit the second sound film to generate The voice.

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.

The first sound film and/or the second sound film is a substrate provided with a metal line, wherein if the first sound film and the second sound film are both a substrate provided with a metal line, the two metals The line is different.

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

According to the above arrangement and structure, since the two sound films share a set of magnets, the conventional technique such as providing two sound films requires more magnets and increases the cost. The second sound effect unit is disposed around the first sound effect unit via the reflection of the speaker structure, so that the second sound effect unit outputs a middle sound, and surrounds the high sound output by the first sound effect unit. The overall sound effect is more stereoscopic, and the conventional 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.

The first and second magnet holders 51 and 52 are a metal frame, and the purpose thereof is to fix the positions of the first and second magnets 510 and 520 respectively, and the whole material can be regarded as a large magnet through the metal material, and the first, The two magnets 510 and 520 respectively face the first and second sound films 31 and 32, and the formed material can be an embodiment of the present invention as long as the magnets are fixed and do not affect the magnetic circuit. The first and second magnets 510 and 520 are a strip magnet. In addition, the first and second magnet holders 51 and 52 are respectively formed with first and second openings 511 and 521. When they are disposed on the sides of the first and second sound films 31 and 32, the first and second openings 511 are The 521 faces the first and second sound films 31 and 32, so that the sound is transmitted when the first and second sound films 31 and 32 vibrate.

The common magnet holder 4 is a metal frame, and the purpose thereof is to fix the position of the common magnet 40 and to make the whole visible as a large magnet through the metal material, as long as the common magnets 40 can be fixed without affecting the magnetic circuit. It can be an embodiment of the creation. The common magnet 40 is a three strip magnet and is disposed in the common magnet holder 4 so as to face the first and second sound films 31 and 32, respectively.

Preferably, the first and second sound films 31, 32 are also fixed by a sound film holder (not shown), and the sound film holder can be a wooden or metal frame as long as the first and second sound films 31 can be The 32-tone film is fixed and does not affect its vibration and affects the magnetic circuit of the magnet, and can be an embodiment of the present invention.

It should be noted that although the three common magnets 40 in the figure are a group, one first magnet 510 is a group, and one second magnet 520 is 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 generated by the speaker, the number, size, and arrangement of the first and second magnets 510 and 520 and the common magnet 40 can be freely tested and adjusted by the user. The best sound is produced with perfect matching of different sound films. In addition, the first magnet 510 and/or the second magnet 520 and/or the common magnet 40 may be at least one large piece of sheet magnet. When the magnets are sheet magnets, the brackets for providing the magnets may be The wooden bracket, because the large piece of magnet is enough to provide a large magnetic field, does not require magnet holder to magnetically increase the magnetic field.

It is known by the prior art that the sound film of the ribbon speaker can be an all-metal belt type sound film and a composite soft base type sound film. Therefore, the first sound film 31 and the second sound film 32 of the present invention can be two The all-metal belt type sound film or the composite soft base type sound film, or one is an all-metal belt type sound film and the other is a composite soft base type sound film.

The improved concept of this creation is to share a set of magnets with two different sound films, thereby saving manufacturing costs, and using this structure to make sound films with different sound effects become a group, thereby improving sound quality, so the first sound The film 31 and the second sound film 32 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. However, as described above, the sound effect emitted by the first sound film 31 is higher than that of the sound produced by the second sound film 32, so that the wrinkle of the formed metal film is adjusted. Density; if the composite soft substrate type sound film needs to be adjusted, the distribution of the metal lines is such that the first sound film 31 emits a high sound and the second sound film 32 emits a middle sound.

In one embodiment shown in the third figure, the first and second sound films 31, 32 are composite soft. The base substrate type sound film is an example. The first sound film 31 is provided with a metal line 311 on an insulating substrate. The two ends of the metal line 311 are respectively connected with different electrodes and face the first opening 511. The formed line and position are arranged such that the first sound film 31 vibrates. Produces a high-pitched sound. The second sound film 32 is provided with a metal line 321 on an insulating substrate. The two ends of the metal line 321 are respectively connected with different electrodes and face the second opening 521, and the formed line and position are arranged such that the second sound film 32 vibrates. Produces a midrange sound. The two electrodes of the metal line 311 of the first sound film 31 and the two electrodes of the metal line 321 of the second sound film 32 may be connected separately or in parallel. In addition, the first sound film 31 and the second sound film 32 can also be middle or high sound sound films, thereby increasing the power of the overall output sound pressure.

The speaker structure 6 is preferably formed in a U-shaped manner on the side of the second magnet holder 52 with respect to the second sound film 32, wherein the notch formed by the speaker structure 6 faces the second opening of the second magnet holder 52. 521. The material of the speaker structure 6 preferably uses a material that is less absorbing sound and can reflect sound, and the surface facing the second magnet holder 52 needs to pay attention to whether the surface has cracks to affect the sound reflection, and the surface can be matched with the position of the second opening 521. The configuration is adjusted to assist in modifying the middle sound produced by the vibration of the second sound film 32. The acoustic structure 6 is a structure prepared by modifying the middle sound generated by the vibration of the second sound film 32, and the size thereof is smaller than that of a general speaker, so that the creation can be reduced in many sizes compared with a general speaker.

Please refer to the fourth figure for a three-dimensional diagram of the speaker prepared by using this creation. The sounding structure 7 can be a sound hole of the front surface of the speaker, and has a first sounding unit 71 and a plurality of second sounding units 72. The second sounding unit 72 and the first sounding unit 71 are separated by a bracket, so that the sounding unit 7 The second sound effect unit 72 surrounds the first sound effect unit 71 disposed on the rectangle. Wherein, the first sound effect unit 71 faces the first opening 511 of the first magnet holder 51, so that the first sound film The high-pitched sound generated by the vibration may be output through the first opening 511 through the first sound effect unit 71 (refer to the arrow A in the third figure), and the second sound film 32 is vibrated to generate the middle sound through the second opening 521. The modification and reflection are adjusted via the speaker structure 6 and output through the second sound effect unit 72 (refer to arrow B of the third figure).

It should be noted that the second sound effect unit 72 surrounds the first sound effect unit 71 disposed in a rectangular shape as the best implementation of the present invention. In addition, two holes may be randomly disposed, so that the first sound effect unit 71 and the first sound effect unit 71 The two acoustic units 72 are respectively output by the two holes.

The first magnet holder 51, the first sound film 31, the common magnet holder 4, the second sound film 32, the second magnet holder 52, and the speaker structure 6 are combined in the above manner to manufacture a speaker using the present construction. If it is compared with the conventional technique shown in the second figure, not only the number of magnets used is small, but also the volume of the forming can be small, and the sound effect superior to the conventional technology can be output, and it is not necessary to additionally provide a speaker.

It should be noted that if you place two originals on both sides of a space and set a woofer at the bottom, you can become a complete sound system. In addition, you can set the creation in a speaker. Set a bass outlet below this creation to become a complete sound.

The above description is only for the purpose of explaining the preferred embodiment of the present invention, and is not intended to impose any form of limitation on the creation, so that any modification or alteration of the creation made in the same creative spirit is provided. , should still be included in the scope of protection of this creative intent.
