Description

These terms are primarily used to distinguish one component from another component or one signal from another signal. In addition, the term "or" used in this article shall, depending on the actual situation, include Any one or combination of multiple items in the associated list.

如圖1和圖2所示，本發明揭示了一種揚聲器的磁性結構，其包括兩個以上採用半導體技術製備得到的線圈組100，兩個以上線圈組100依次排列，且至少一線圈組100設有振動空間。線圈組100設有振動空間則表示，該線圈組100與相鄰的線圈組100、或揚聲器殼體之間存在間距。 As shown in Figures 1 and 2, the present invention discloses a magnetic structure of a speaker, which includes two or more coil groups 100 prepared using semiconductor technology. The two or more coil groups 100 are arranged in sequence, and at least one coil group 100 is configured There is room for vibration. If the coil group 100 is provided with a vibration space, it means that there is a distance between the coil group 100 and the adjacent coil group 100 or the speaker housing.

其中，每一線圈組100均設有信號輸入端，而設有振動空間的線圈組100的信號輸入端既可以連接聲音信號，也可以連接電源信號。當連接聲音信號時，該線圈組100作為揚聲器的音圈使用；當連接電源信號時，該線圈組100作為電磁鐵使用。而無振動空間的線圈組100的信號輸入端只能連接電源信號，作為電磁鐵使用，無法作為音圈使用。 Each coil group 100 is provided with a signal input terminal, and the signal input terminal of the coil group 100 provided with a vibration space can be connected to either a sound signal or a power signal. When a sound signal is connected, the coil group 100 is used as a voice coil of a speaker; when a power signal is connected, the coil group 100 is used as an electromagnet. The signal input end of the coil group 100 without vibration space can only be connected to the power signal and is used as an electromagnet, but cannot be used as a voice coil.

因此，在設計線圈組100時，設有振動空間的線圈組100包括振動層101、及一層以上的線圈層102，所述線圈層102設於振動層101上；而無振動空間的所述線圈組100包括一層以上線圈層102，可以不用增設振動層101。當線圈組100包括兩層以上的線圈層102時，兩層以上的線圈層102相互疊加在一起，且各線圈層102之間既可以進行串聯，也可以進行並聯。當然，為了生產方便，也可以將所有的線圈組100設計為相同結構，即均包括振動層101和線圈層102。 Therefore, when designing the coil group 100, the coil group 100 with a vibration space includes a vibration layer 101 and more than one coil layer 102. The coil layer 102 is provided on the vibration layer 101; while the coil without a vibration space The group 100 includes more than one coil layer 102, and there is no need to add a vibration layer 101. When the coil group 100 includes two or more coil layers 102, the two or more coil layers 102 are superimposed on each other, and the coil layers 102 can be connected in series or in parallel. Of course, for the convenience of production, all coil groups 100 can also be designed to have the same structure, that is, they all include a vibration layer 101 and a coil layer 102 .

在使用時，根據具體使用情況，可以將揚聲器磁性結構中的線圈組100選擇性地接入電源信號或聲音信號，從而改變揚聲器的可播放聲音強或聲音方向。例如，需要增加揚聲器的可播放的聲音強度時，可以將其中一個線圈組100接入聲音信號作為音圈使用，其他線圈組100則均接入電源信號作為電磁鐵使用，從而增加揚聲器的磁場強度，進而增加揚聲器的可播放聲音強度。當需要減弱揚聲器的可播放聲音強度時，只要減少連接電源信號的線圈組100數量即可。 During use, depending on specific usage conditions, the coil group 100 in the magnetic structure of the speaker can be selectively connected to a power signal or a sound signal, thereby changing the playable sound intensity or sound direction of the speaker. For example, when it is necessary to increase the playable sound intensity of a speaker, one of the coil groups 100 can be connected to a sound signal to be used as a voice coil, and the other coil groups 100 can be connected to a power signal to be used as electromagnets, thereby increasing the magnetic field strength of the speaker. , thereby increasing the playable sound intensity of the speaker. When it is necessary to reduce the playable sound intensity of the speaker, it is only necessary to reduce the number of coil groups 100 connected to the power signal.

為了進一步增加揚聲器使用的靈活性，線圈組100還可以由一個以上的子線圈組構成。當線圈組100包括兩個以上子線圈組時，兩個子線圈組100處於同一平面，且該平面於與子線圈組相鄰的線圈組100。當線圈組100由兩個以上的子線圈組構成時，可以增加揚聲器的可播放聲音的頻率、也可以穩定揚聲器播放聲音的音質。 In order to further increase the flexibility of using the speaker, the coil set 100 can also be composed of more than one sub-coil set. When the coil group 100 includes more than two sub-coil groups, the two sub-coil groups 100 are on the same plane, and the plane is on the coil group 100 adjacent to the sub-coil group. When the coil group 100 is composed of two or more sub-coil groups, the frequency of the sound that the speaker can play can be increased, and the sound quality of the sound played by the speaker can also be stabilized.

為了能夠更好地說明揚聲器使用靈活性，以下將列舉六個實施例進行說明。 In order to better illustrate the flexibility of using the loudspeaker, six embodiments will be listed below for description.

實施例一 Embodiment 1

如圖3所示，該實施例中，揚聲器的磁性結構包括兩線圈組，即第一線圈組111和第二線圈組112，兩線圈組均設有振動空間。在使用時，可以通過改變第一線圈組111和第二線圈組112的輸入，即可改變揚聲器的發聲方向。 As shown in Figure 3, in this embodiment, the magnetic structure of the speaker includes two coil groups, namely a first coil group 111 and a second coil group 112. Both coil groups are provided with vibration spaces. During use, the sound emission direction of the speaker can be changed by changing the inputs of the first coil group 111 and the second coil group 112 .

具體地，當第一線圈組111的信號輸入端輸入電源信號，第二線圈組112的信號輸入端輸入聲音信號時，揚聲器的發聲方向朝下；當第一線圈組111的信號輸入端輸入聲音信號，而第二線圈組112的信號輸入端輸入電源信號時，揚聲器的發聲方向朝上。 Specifically, when the signal input terminal of the first coil group 111 inputs a power signal and the signal input terminal of the second coil group 112 inputs a sound signal, the sound emitting direction of the speaker is downward; when the signal input terminal of the first coil group 111 inputs sound signal, and when the signal input terminal of the second coil group 112 inputs the power signal, the sound emission direction of the speaker is upward.

實施例二 Embodiment 2

如圖4所示，在上述實施例一的基礎上，第一線圈組121由兩個子線圈組1211構成。該實施例中，通過改變第一線圈組121和第二線圈組122的輸入，除了可以改變發聲方向外，還可以改變聲音頻率。 As shown in FIG. 4 , based on the above-mentioned Embodiment 1, the first coil group 121 is composed of two sub-coil groups 1211 . In this embodiment, by changing the inputs of the first coil group 121 and the second coil group 122, in addition to changing the sound emission direction, the sound frequency can also be changed.

具體地，當第一線圈組121的信號輸入端輸入電源信號，第二線圈組122的信號輸入端輸入聲音信號時，揚聲器的發聲方向朝下，此時，第二線圈組122的振動也更加穩定，可以改善揚聲器播放的聲音音質。而當第一線圈組121的信號輸入端輸入聲音信號，第二線圈組122的信號輸入端輸入電源 信號時，第一線圈組121的兩個子線圈組1211振動發聲，聲音朝上，且發聲頻率有兩個。在該情況下，若第一線圈組121包括三個子線圈組1211，則該揚聲器的發聲頻率則為三個以上。 Specifically, when the signal input terminal of the first coil group 121 inputs a power signal and the signal input terminal of the second coil group 122 inputs a sound signal, the sound emitting direction of the speaker is downward. At this time, the vibration of the second coil group 122 is also more intense. Stable and can improve the sound quality of the speaker. When the signal input terminal of the first coil group 121 inputs a sound signal, the signal input terminal of the second coil group 122 inputs power. When the signal is generated, the two sub-coil groups 1211 of the first coil group 121 vibrate and sound, the sound is directed upward, and the sound frequency has two. In this case, if the first coil group 121 includes three sub-coil groups 1211, the sound frequency of the speaker is three or more.

實施例三 Embodiment 3

如圖5所示，該實施例中，揚聲器的磁性結構包括三個線圈組，即第一線圈組131、第二線圈組132和第三線圈組133，三個線圈組均設有振動空間。該實施例中，通過改變三個線圈的輸入，既可以改變揚聲器的聲音的方向，也可以改變聲音的強度。 As shown in Figure 5, in this embodiment, the magnetic structure of the speaker includes three coil groups, namely the first coil group 131, the second coil group 132 and the third coil group 133. Each of the three coil groups is provided with a vibration space. In this embodiment, by changing the inputs of the three coils, the direction of the sound from the speaker can be changed, and the intensity of the sound can also be changed.

例如，當第一線圈組131和第三線圈組133的信號輸入端輸入聲音信號，第二線圈組132的信號輸入端輸入聲音信號時，該揚聲器具有兩個發聲方向。而當第一線圈組131和第三線圈組133的信號輸入端輸入電源信號，第二線圈組132的信號輸入端輸入聲音信號時，該揚聲器只有一個發聲方向，但其聲音強度會增強。當第一線圈組131、第二線圈組132的信號輸入端輸入電源信號，第三線圈組133的信號輸入端輸入聲音信號；或者，第二線圈組132、第三線圈組133的信號輸入端輸入電源信號，第一線圈組131的信號輸入端輸入聲音信號，同樣也可以將揚聲器的發聲方向減少，同時增強其聲音強度。 For example, when a sound signal is input to the signal input end of the first coil group 131 and the third coil group 133, and a sound signal is input to the signal input end of the second coil group 132, the speaker has two sound emission directions. When the signal input terminals of the first coil group 131 and the third coil group 133 input a power signal, and the signal input terminal of the second coil group 132 inputs a sound signal, the speaker has only one sound direction, but its sound intensity will be enhanced. When the signal input terminals of the first coil group 131 and the second coil group 132 input a power signal, the signal input terminal of the third coil group 133 inputs a sound signal; or, the signal input terminals of the second coil group 132 and the third coil group 133 When a power signal is input and a sound signal is input to the signal input terminal of the first coil group 131, the sound emission direction of the speaker can also be reduced and its sound intensity can be enhanced at the same time.

實施例四 Embodiment 4

如圖6所示，在上述實施例三的基礎上，本實施例的第一線圈組141和第三線圈組143均包括兩個子線圈組1411、1431。通過改變各線圈組的輸入，除了可以改變揚聲器發聲方向、強度，還可以改變其發聲頻率和音質。 As shown in FIG. 6 , based on the above-described third embodiment, the first coil group 141 and the third coil group 143 of this embodiment each include two sub-coil groups 1411 and 1431 . By changing the input of each coil group, in addition to changing the direction and intensity of the speaker's sound, it can also change its sound frequency and sound quality.

例如，當第一線圈組141和第三線圈組143的信號輸入端輸入聲音信號，第二線圈組142的信號輸入端輸入聲音信號時，該揚聲器具有兩個發聲方向，且每個發聲方向上具有兩個發聲頻率。而當第一線圈組141和第三線 圈組143的信號輸入端輸入電源信號，第二線圈組142的信號輸入端輸入聲音信號時，該揚聲器只有一個發聲方向，但其聲音強度會增強，且其發出其音質更穩定。 For example, when the signal input terminals of the first coil group 141 and the third coil group 143 input sound signals, and the signal input terminal of the second coil group 142 inputs the sound signal, the speaker has two sound emission directions, and each sound emission direction Has two sounding frequencies. And when the first coil set 141 and the third wire When the signal input terminal of the coil group 143 inputs a power signal and the signal input terminal of the second coil group 142 inputs a sound signal, the speaker has only one sound direction, but its sound intensity will be enhanced and its sound quality will be more stable.

實施例五 Embodiment 5

如圖7所示，該實施例中，揚聲器的磁性結構包括五個線圈組，即第一線圈組151、第二線圈組152、第三線圈組153、第四線圈組154和第五線圈組155，其中，第一線圈組151無振動空間，其餘線圈組均設有振動空間。通過改變第二至第五線圈組的輸入，既可以改變揚聲器的聲音的方向，也可以改變聲音的強度。 As shown in Figure 7, in this embodiment, the magnetic structure of the speaker includes five coil groups, namely the first coil group 151, the second coil group 152, the third coil group 153, the fourth coil group 154 and the fifth coil group. 155. Among them, the first coil group 151 has no vibration space, and the other coil groups are all provided with vibration space. By changing the input of the second to fifth coil groups, both the direction and intensity of the sound from the speaker can be changed.

At this time, the speaker has two sound emission directions, and the sound intensity in the two sound emission directions is the same. When the signal input terminals of the first coil group 151, the second coil group 152, and the fourth coil group 154 input power signals, and the signal input terminals of the third coil group 153, and the fifth coil group 155 input sound signals, at this time, the speaker is still It has two sound emission directions, but the sound intensity in the two sound emission directions is different. When the signal input terminals of the first coil group 151, the second coil group 152, the fourth coil group 154, and the fifth coil group 155 input a power signal, and the signal input terminal of the third coil group 153 inputs a sound signal, the speaker only A sound direction, but its sound intensity is indeed the largest.
