Description

Technical Field

[0001] The embodiments of the present invention relate to the field of audio equipment, and in particular to a speaker and an electronic device. Background Art

[0002] Compared with the existing multifunctional speakers with a single function, the difference is that the multifunctional speakers have a cantilever and a weight component, so that the multifunctional speakers have a vibrator function. Figure 1 As shown, the cantilever, weight component, magnetic bowl, magnet and top plate of the multifunctional speaker form a vibrator elastic system, wherein the cantilever is used to adjust the elasticity of the vibrator elastic system, and the total weight of the weight component, magnetic bowl, magnet and top plate is used to adjust the vibration mass of the vibrator elastic system. The resonant frequency and vibration effect of the vibrator elastic system are achieved by adjusting the elasticity and weight of the vibrator elastic system. Generally, the vibration effect is measured by the magnitude of acceleration.

[0003] The theoretical resonant frequency of the vibrator elastic system of the existing multifunctional speaker is 157Hz. When the vibrator elastic system is working, the input signal is a 157Hz sine wave signal. After the speaker receives the excitation signal near 157Hz, the amplitude of the vibrator elastic system reaches a peak value, and the vibrator elastic system will drive the speaker and the electronic equipment fixed to the speaker to vibrate. The vibrator elastic system can reach the maximum amplitude near 157Hz, and the amplitude drops rapidly in other frequency bands, such as Figure 2 For mass-produced products, the resonant frequency of the oscillator elastic system of multiple individual products cannot be precisely controlled within 157 Hz, but can only be within a narrow range, such as Figure 2 For some products whose resonant frequency deviates greatly from 157Hz, if they are still excited by an input signal of 157Hz, the resonant frequency of the oscillator elastic system will not match the input signal frequency, and the effective acceleration value cannot be achieved, resulting in poor product performance.

[0070] Embodiment 1:

[0071] Figure 3 FIG. 1 is a cross-sectional schematic diagram of a loudspeaker according to an embodiment of the present invention. Figure 3 As shown, the loudspeaker includes a vibration system A, a magnetic circuit system B, a damping system D and a housing E. The vibration system A and the magnetic circuit system B are fixedly arranged in the housing E. Specifically, the vibration system A includes a diaphragm 1 and a voice coil 2. The first end of the voice coil 2 is fixedly connected to the diaphragm 1, and the second end of the voice coil 2 is arranged in the magnetic gap area formed by the magnetic circuit system B. The voice coil 2 drives the diaphragm 1 to vibrate and make sound under the action of the magnetic field formed in the magnetic circuit system B. At the same time, the vibration system B can also vibrate after receiving the excitation signal, thereby driving the loudspeaker and the electronic device equipped with the loudspeaker to vibrate. The damping system D is arranged between the magnetic circuit system B and the housing E. When the magnetic circuit system B vibrates, the damping system D generates damping, so that the vibration amplitude of the magnetic circuit system B gradually decreases and the frequency band becomes wider.

[0072] In this embodiment, the damping system D includes a first damping structure 3 and a resistance component 5. A downwardly open accommodation cavity C is provided at the bottom of the magnetic circuit system B, the first damping structure 3 is provided in the accommodation cavity C, and the resistance component 5 is connected to the first damping structure 3 through the housing E. When the magnetic circuit system B vibrates, the resistance component 5 and the first damping structure 3 rub against each other to generate damping, so that the vibration amplitude of the magnetic circuit system B gradually decreases and the frequency band becomes wider.

[0073] Specifically, the magnetic circuit system B includes a magnet 6, a top plate 7 and a magnetic bowl 8. The magnet 6 is arranged in the magnetic bowl 8, and the top plate 7 is arranged on the top of the magnet 6. An annular magnetic gap area is formed between the magnet 6, the top plate 7 and the magnetic bowl 8, which is used to generate a magnetic field. The voice coil 2 can vibrate under the action of the magnetic field, thereby driving the diaphragm 1 to vibrate and make sounds. A first damping hole 81 is provided at the bottom of the magnetic bowl 8, and the first damping hole 81 can form a housing cavity C for accommodating the first damping structure 3. In this embodiment, the first damping hole 81 can be set as a through hole or a blind hole. The damping material is filled according to the size of the first damping hole 81 to form the corresponding first damping structure 3. The material of the first damping structure 3 is paste-like or jelly-like, and the first damping structure 3 can be formed by damping paste or paste-like white oil. When making a speaker, the damping paste or paste-like white oil is filled in the first damping hole 81 to form the first damping structure 3.

[0074] The housing E includes a rear housing 4, a basin frame 9 and a front housing 12. The basin frame 9 is used to fix the vibration system A and the magnetic circuit system B. The rear housing 4 is fixedly connected to the lower side of the basin frame 9 to form a rear cavity, and the front housing 12 is fixedly connected to the upper side of the basin frame 9 to fix the vibration system A and form a front cavity. In this embodiment, the outer side of the diaphragm 1 is arranged at the top of the basin frame 9, and the front housing 12 is arranged above the diaphragm 1, and is fixedly connected to the basin frame 9 by bolts, bonding or clamping to fix the diaphragm 1.

[0075] Specifically, the rear shell 4 is arranged at the lower side of the magnetic circuit system B, and forms a rear cavity with the magnetic circuit system B. The rear shell 4 is provided with a fixed through hole 41, wherein the position of the fixed through hole 41 corresponds to the position of the first damping hole 81, so that the resistance component 5 can pass through the fixed through hole 41 and contact the first damping structure 3 arranged in the first damping hole 81. When the magnetic circuit system B vibrates upon receiving an excitation signal, the resistance component 5 and the first damping structure 3 generate opposite forces, that is, damping, so that the vibration amplitude of the magnetic circuit system B gradually decreases and the frequency band becomes wider, such as Figure 6 In this embodiment, the cross section of the resistance component 5 is smaller than the cross section of the first damping hole 81, so that a gap is formed between the side of the resistance component 5 and the side of the first damping hole 81, which can avoid direct contact between the resistance component 5 and the magnetic bowl 8 and affect the vibration effect of the magnetic circuit system B.

[0076] In the present embodiment, the resistance component 5 has a first part and a second part. The cross section of the first part is larger than the cross section of the second part, so that the first part and the second part form a step, such as a rivet, a bolt, etc. Among them, the outer diameter of the second part is adapted to the inner diameter of the fixing through hole 41, that is, the fixing through hole 41 is smaller than the first damping hole 81. After the resistance component 5 passes through the fixing through hole 41, the second part of the resistance component 5 contacts the first damping structure 3, and the first part is clamped on the outside of the rear shell 4. In the present embodiment, the first damping hole 81 and the fixing through hole 41 can be set as a circular hole, a square hole or other holes with any cross section, and correspondingly, the second part of the resistance component 5 is set to have a cross-sectional structure with the same shape as the fixing through hole 41. Preferably, the first damping hole 81 and the fixing through hole 41 are set as circular holes, which can be easily processed and manufactured.

[0077] In another optional implementation, a plurality of first damping holes 81 may be provided at the bottom of the magnetic bowl 8, which may be specifically set as required. Correspondingly, the speaker includes a plurality of first damping structures 3 and a plurality of resistance components 5, and the number of the first damping structures 3 and the resistance components 5 is the same as the number of the first damping holes 81. Figure 4 and Figure 5 When the bottom of the magnetic bowl 8 is provided with a plurality of first damping holes 81, the rear shell 4 is provided with the same number of fixing through holes 41 as the first damping holes 81. The plurality of fixing through holes 41 correspond to the positions of the plurality of first damping holes 81 one by one. After the plurality of first damping structures 3 are respectively placed in the corresponding first damping holes 81, the plurality of resistance components 5 are respectively passed through the corresponding fixing through holes 41 to be in contact and connected with the corresponding first damping structures 3.

[0078] In this embodiment, the cross-sectional shapes and sizes of the plurality of first damping holes 81 can be set to be the same or different, the fixed through holes 41 at the corresponding positions are set to have the same cross-section as the corresponding first damping holes 81, and the first damping structure 3 filled in the corresponding first damping holes 81 can be filled and generated according to actual needs, and the cross-section of the second part of the resistance component 5 at the corresponding position is the same as the cross-section of the corresponding fixed through hole 41. Preferably, the plurality of first damping holes 81 can be set to the same structure, that is, have the same cross-section and size, and correspondingly, the plurality of fixed through holes 41 and the plurality of resistance components 5 can also be set to the same structure, respectively, and respectively match the first damping hole 81, so as to improve the manufacturing efficiency of the speaker. Preferably, the plurality of first damping holes 81 can be evenly arranged at the bottom of the magnetic bowl 8, so that the magnetic circuit system B can generate vibration evenly, thereby improving the vibration effect.

[0079] Figure 7 FIG. 1 is a schematic diagram of acceleration spectrum curves of the magnetic circuit system of the multiple speakers in this embodiment near their own resonant frequencies. Figure 7 It can be seen that for mass-produced speaker products, the resonant frequency of the magnetic circuit system of multiple speakers cannot be accurately controlled at 157Hz. In other words, the magnetic circuit systems of multiple speakers have different resonant frequencies. Since the frequency band of the magnetic circuit system is widened, when multiple speakers are excited at 157Hz, the magnetic circuit system of the speaker can reach an effective acceleration value within the frequency band width, so that the magnetic circuit system can achieve effective vibration. In this embodiment, since the magnetic circuit system has increased damping, the acceleration frequency band of the magnetic circuit system is widened but the amplitude is reduced, which can be improved by increasing the amplitude of the excitation signal when the excitation signal is input.

[0080] In the present embodiment, the magnetic circuit system B further includes a cantilever 11 and a counterweight component 10. The counterweight component 10 is disposed below the outer side of the magnetic bowl 8, and the outer side of the counterweight component 10 is not in contact with the outer shell E. The counterweight component 10 is used to adjust the vibration mass of the entire magnetic circuit system B to adjust the vibration effect of the magnetic circuit system B. The inner side of the cantilever 11 is fixed between the magnetic bowl 8 and the counterweight component 10, and the outer side of the cantilever 11 is fixedly connected to the basin frame 9. The cantilever 11 is configured to drive the magnet 6, the top sheet 7, the magnetic bowl 8 and the counterweight component 10 to vibrate. In the present embodiment, the counterweight component 10 and the cantilever 11 are made of non-magnetic materials such as plastic, and will not affect the magnetic field formed by the magnet 6, the top sheet 7 and the magnetic bowl 8.

[0081] In another optional implementation, the damping system D further includes a second damping structure 31. The materials of the second damping structure 31 and the first damping structure 3 are both paste-like or jelly-like. The second damping structure 31 can be formed by damping paste or paste-like white oil. The outer side of the counterweight component 10 can also be provided with a plurality of protrusions 101, and the basin frame 9 is provided with a plurality of grooves 91 at positions opposite to the protrusions 101, and there is a small gap between the grooves 91 and the protrusions 101. The second damping structure 31 can be provided in the gap between the grooves 91 and the protrusions 101, connecting the basin frame 9 and the counterweight component 10, such as Fig.13 and Fig.14 Preferably, the plurality of protrusions 101 can be symmetrically and evenly arranged on the outside of the weight component 10, so that the magnetic circuit system B can be subjected to uniform resistance when vibrating, thereby producing a good vibration effect. The shape and number of the grooves 91 and the protrusions 101 can be set according to requirements.

[0082] In this embodiment, the speaker is a circular structure, that is, the outer shapes of all parts included in the speaker are circular. Figure 5 In another optional implementation, the speaker may also be configured as a square structure.

Among them, the first damping hole 81 is connected with the corresponding second damping hole 61 to form a receiving cavity C for receiving the first damping structure 3.

Preferably, the plurality of protrusions 101 can be symmetrically and evenly arranged on the outside of the counterweight component 10, so that the magnetic circuit system B can be subjected to uniform resistance when vibrating, thereby producing a good vibration effect.
