Description

[Technical Field]

[0001] This invention relates to a Heil driver, and in particular to a Heil driver structure that can perform audio frequency compensation by installing two circuits with different characteristics on the sound membrane. [Background technology]

[0002] The Heil driver (Air Motion Transformer) is a high-end audio device commonly used in high-end speakers and earphones. The sound generation principle of a conventional driver is that multiple magnets are placed in a magnetic holder and a sound membrane is placed above it, i.e., hung on the holder. When the high-frequency driver is energized, the magnetic force alternately presses and pushes the sound membrane, generating sound that is transmitted through the compression of air.

[0003] This design is highly efficient, and the strong magnetic force on the sound membrane reduces the effective mass reactance and impedance, hence the name "AMT driver." As can be seen from the above, the Heil driver folds the flat sound membrane and uses the principle of compression to make the air flow, and since the amount of air flowing is greater than with a conventional flat sound membrane, it is more efficient.

[0004] However, in the above-mentioned conventional Heil driver structure, only one sound membrane is used, and the sound produced by only one sound membrane is monotonous and uncontrollable. However, in a situation where there are many music genres and sound effects are becoming more and more abundant, the structure that produces sound by a single sound membrane is increasingly unable to fully express the musical effects.

[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings and part numbers, so that those skilled in the art can implement the present invention after reading the specification.

[0020] FIG. 1 is a schematic diagram illustrating the structure of a compensable Heil driver according to an embodiment of the present invention, and FIG. 2 is a schematic diagram illustrating the implementation structure of a compensable Heil driver according to an embodiment of the present invention.

[0021] 1 and 2, in one embodiment of the present invention, a compensable Heil driver 1 includes a base 10, a holder 20, a plurality of magnets 30, at least one sound membrane 40, and an outer base 50. The holder 20 includes an upper housing 201 and a lower housing 203, the upper housing 201 and the lower housing 203 being in communication with each other, and the holder 20 is installed on the base 10.

[0022] The plurality of magnets 30 are disposed in the lower housing 203. The sound membrane 40 is disposed in the upper housing 201, and includes a sound source signal circuit 401 on one surface of the sound membrane 40 and a compensation signal control circuit 403 on the other surface of the sound membrane 40. For example, the sound source signal circuit 401 may be disposed on the front surface of the sound membrane 40 and the compensation signal control circuit 403 may be disposed on the rear surface of the sound membrane 40. It should be understood that the sound source signal circuit 401 and the compensation signal control circuit 403 may be printed on the front and rear surfaces of the sound membrane 40 by printing.

[0023] The external base 50 includes a plurality of openings 501, a left side wall 503, a right side wall 505, a front side wall 507, and a rear side wall 509, and is fitted outside the base 10, the holder 20, the magnet 30, and the sound membrane 40. One end of the sound source signal circuit 401 is joined to the left side wall 503 to form a first audio control junction P11, the other end of the sound source signal circuit 401 is joined to the right side wall 505 to form a second audio control junction P13, one end of the compensation signal control circuit 403 is joined to the left side wall 503 to form a first compensation frequency control junction P21, and the other end of the compensation signal control circuit 403 is joined to the right side wall 505 to form a second compensation frequency control junction P23.

[0024] The audio signal controller 60 is connected to the first audio control junction P11 and the second audio control junction P13 to form a first circuit, and the compensation frequency controller 70 is connected to the first compensation frequency control junction P21 and the second compensation frequency control junction P23 to form a second circuit.

[0025] It should be understood that for convenience of illustration, only the sound membrane 40, the sound source signal circuit 401, and the compensation signal control circuit 403 are shown inside the compensable Heil driver in Fig. 2. Although the outer base 50 of the present invention is described as including a left side wall 503, a right side wall 505, a front side wall 507, and a rear side wall 509, the terms "left, right, front, rear" are used merely to clearly define the positions of the side walls and to facilitate the description of the positions of the joints, and the structure of the present invention is not limited to the direction of the side walls; in other words, the front and rear directions can be interchanged, or the left and right directions can be interchanged.

[0026] In addition, in one embodiment of the present invention, the first audio control junction P11, the second audio control junction P13, the first compensation frequency control junction P21, and the second compensation frequency control junction P23 may be welded points, in other words, the sound source signal circuit 401 and the compensation signal control circuit 403 can be electrically connected to the first audio control junction P11, the second audio control junction P13, the first compensation frequency control junction P21, and the second compensation frequency control junction P23, respectively.

[0027] FIG. 3a is a schematic diagram illustrating the frequency signal of an audio signal according to an embodiment of the present invention, and FIG. 3b is a schematic diagram illustrating the frequency signal of a compensation frequency according to an embodiment of the present invention.

[0028] 2, 3a and 3b, in one embodiment of the present invention, the audio signal controller 60 can control the audio source signal circuit 401 to emit a signal with a frequency of 5-100K Hz as shown in FIG. 3a, and the compensation frequency controller 70 can control the compensation signal control circuit 403 to emit a corresponding compensation frequency according to a user's setting, for example, an amplified signal with a frequency of 5+X or 100K-Y Hz as shown in FIG. 3b, where X and Y are any natural numbers.

[0029] Therefore, in this embodiment, the second circuit in which the compensation frequency controller 70 is configured may be an amplifier circuit whose signals enter and exit on the same side as the signals emitted by the audio signal controller 60, and the amplifier circuit can increase the audio intensity in a predetermined frequency band.

[0030] 3c is a schematic diagram illustrating a frequency signal of a compensation frequency in another embodiment of the present invention. Referring to FIGS. 2, 3a, and 3c, in one embodiment of the present invention, the audio signal controller 60 controls the audio source signal circuit 401 to generate a signal with a frequency of 5-100 kHz as shown in FIG. 3a, and the compensation frequency controller 70 controls the compensation signal control circuit 403 to generate an inverse signal of the corresponding compensation frequency according to a user setting, for example, an attenuation signal with a frequency of 5+a or 100 kHz-b as shown in FIG. 3c, where a and b are any natural numbers.

[0031] Therefore, in this embodiment, the second circuit in which the compensation frequency controller 70 is configured may be an attenuation circuit in which a signal flows in and out in the opposite direction to the signal emitted by the audio signal controller 60, and the attenuation circuit can attenuate the audio intensity in a predetermined frequency band.

[0032] As can be seen from the above embodiment, the present invention has two circuits with different functions installed on the sound membrane 40: one is the sound source signal circuit 401, and the other is the compensation signal control circuit 403, which are respectively connected to the audio signal controller 60 and the compensation frequency controller 70. In this way, the compensated Heil driver 1 of the present invention, while outputting sound, controls the compensation signal control circuit 403 to output the frequency of the audio to be compensated by the compensation frequency controller 70, thereby achieving the purpose of boosting or attenuating the audio in a certain frequency band, enriching the audio effect, and compensating or adjusting the audio according to different music genres, thereby optimizing the audio effect.

[0033] 4 is a schematic diagram of the structure of a compensable Heil driver according to another embodiment of the present invention. Referring to FIG. 4, in this embodiment of the present invention, the structure of the compensable Heil driver 2 is basically the same as the compensable Heil driver 1 shown in FIG. 1, except that the base 10 includes a plurality of openings 101, and the number of openings 101 is equal to the number of openings 501 of the outer base, and their positions correspond to each other.

[0034] In this way, the sound output from the sound source signal circuit 401 and the compensation sound output from the compensation signal control circuit 403 can be output simultaneously from the front and rear ends of the compensating Heil driver 2, making the sound effect more three-dimensional and surround, and providing the user with a better sound experience. In addition, the base opening 101 has the same aperture number as the outer base opening 501 and their positions correspond to each other, so that the front and rear pressures of the two signal circuits with different functions can be balanced, improving the smoothness of the audio and sound, and achieving a higher high-frequency response and a lower low-frequency response.

[0035] 5a is a schematic diagram illustrating the cross-sectional structure of an opening in yet another embodiment of the present invention. It should be understood that for the sake of convenience of explanation and illustration, only the base 10, the base opening 101, the outer base 50, and the outer base opening 501 are shown in FIG. 5a. Referring to FIG. 5a, in yet another embodiment of the present invention, each base opening 101 is an inverted V-shaped opening, and each outer base opening 501 is a V-shaped opening. This structure increases the opening area of ​​the base opening 101 and the outer base opening 501, thereby enhancing the volume and realism of the sound, and the V-shaped opening also has the effect of collecting and amplifying the sound.

[0036] Figure 5b is a schematic diagram illustrating the cross-sectional structure of an opening in yet another embodiment of the present invention. It should be understood that for the sake of convenience of explanation and illustration, Figure 5b similarly only shows the base 10, base opening 101, outer base 50, and outer base opening 501. Referring to Figure 5b, in yet another embodiment of the present invention, each base opening 101 is a double-V opening, and the double-V base opening 101 is composed of a V-shaped opening 1011 and an inverted V-shaped opening 1013. Each outer base opening 501 is also a double-V opening, and the double-V outer base opening 501 is similarly composed of a V-shaped opening 5011 and an inverted V-shaped opening 5013. This increases the opening area of ​​the base opening 101 and the outer base opening 501, thereby enhancing the volume and realism of the sound, and the double-V opening also has the effect of collecting and amplifying the sound.

[0037] It should be understood that the opening structures shown in Figures 5a and 5b can both be applied to the structure of the compensable Heil driver 1 shown in Figure 1 and the structure of the compensable Heil driver 2 shown in Figure 4. In other words, in the structure of the compensable Heil driver 1 including only the opening 501 of the external base, only the opening 501 of the external base can be configured as a V-shaped opening or a double V-shaped opening, which can enhance the volume and realism of the opening 501 of the external base.

[0038] Fig. 6 is a schematic diagram illustrating the structure of a sound membrane in yet another embodiment of the present invention. Referring to Fig. 1, Fig. 2 and Fig. 6, in yet another embodiment of the present invention, a plurality of sound membranes 40 can be installed, for example, two sound membranes 40 as shown in Fig. 6, and both sound membranes 40 are installed in the upper storage section 201.

[0039] Furthermore, one surface of each sound membrane 40 includes a sound source signal circuit 401, and the other surface of each sound membrane 40 includes a compensation signal control circuit 403, and the sound source signal circuit 401 and compensation signal control circuit 403 of each sound membrane 40 can be connected to the audio signal controller 60 and the compensation frequency controller 70 according to the embodiment shown in Figure 2, thus forming a multi-layered membrane and multi-circuit structure, which can increase the intensity and three-dimensionality of the sound effect and further increase the variable frequency adjustment method. It should be understood that the number of sound membranes 40 may be two or more.

[0040] As can be seen from the above description of the present invention, the present invention provides a compensated Heil driver, and includes the following effects and advantages: 1. The sound membrane includes two signal circuits with different functions, one is a sound source signal circuit and the other is a compensation signal control circuit, which are respectively connected to an audio signal controller and a compensation frequency controller.
