Description
Technical Field
The embodiment of the utility model relates to the technical field of speakers, in particular to a speaker and electronic equipment.
Background
At present, most of loudspeakers of notebook computers use a common moving-coil single-sided vibrating diaphragm loudspeaker, and the vibration principle is based on electromagnetic induction and vibration transmission, and the amplification and playing of audio frequency are realized by converting an electric signal into a sound signal.
In operation, an electrical signal is passed through a coil in the driver to generate a magnetic field force under the influence of a magnetic field, thereby causing the diaphragm to vibrate, which converts electrical energy into mechanical energy, thereby producing sound. Meanwhile, the vibration energy of the voice coil can be transferred to the support of the loudspeaker, and the support transfers the vibration energy to the shell of the loudspeaker, so that the resonance of the whole notebook computer can be caused.
In order to solve such resonance phenomenon, the existing solutions are:
1. The acoustic performance of the loudspeaker unit is regulated, the vibration amplitude of the voice coil is reduced, so that the vibration energy transferred to the bracket is reduced, and then the vibration energy transferred to the loudspeaker shell is also reduced, thereby reducing the resonance risk of the whole loudspeaker;
2. Vibration reduction foam is stuck on the outer wall of the loudspeaker shell, so that the resonance risk of the whole loudspeaker is reduced;
3. The double-sided vibrating diaphragm loudspeaker is used, and the resonant risk is greatly reduced by using the design that the vibration quantity of the eardrums of the two loudspeakers is the same but the vibration directions are opposite when the two loudspeakers work.
However, the scheme 1 sacrifices the low-frequency performance of the speaker unit, so that the low-frequency performance of the whole notebook computer is also deteriorated; scheme 2 is when the vibration energy is too big, the bubble cotton can not completely eliminate resonance, and the cost is increased; scheme 3 is that double-sided diaphragm loudspeaker cost is high, and on average 3-4 gold is more expensive than ordinary loudspeaker, can only be used on high-end model, and low-end model can not be adopted, namely the universality is poor.

Specific embodiments of the present disclosure will be described hereinafter with reference to the accompanying drawings; however, it is to be understood that the disclosed embodiments are merely examples of the disclosure, which may be embodied in various forms. Well-known and/or repeated functions and constructions are not described in detail to avoid obscuring the disclosure in unnecessary or unnecessary detail. Therefore, specific structural and functional details disclosed herein are not intended to be limiting, but merely serve as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.
The specification may use the word "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the disclosure.
Hereinafter, embodiments of the present utility model will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, it can be seen from the figure that the support and the magnetic circuit are rigidly connected, so that when the loudspeaker is in operation, the vibration energy of the voice coil mounted on the support is transferred to the support through the magnetic circuit, and is transferred to the shell of the loudspeaker, and the shell drives the whole electronic equipment to resonate.
In order to solve the above problems, as shown in fig. 2, an embodiment of the present utility model provides a speaker, including:
A bracket mechanism 1;
The magnetic circuit system 2 is arranged on the bracket mechanism 1;
a voice coil 3 arranged on the bracket mechanism 1 and connected with the magnetic circuit system 2
The vibrating diaphragm assembly 4 is arranged on the bracket mechanism 1 and covers the magnetic circuit system 2 and the voice coil 3;
wherein, the support mechanism 1 is flexibly connected with the magnetic circuit system 2.
In the present embodiment, the specific structure of the stand mechanism 1 is not limited, and may be comprehensively determined according to the shape, structure, size, etc. of the speaker actually required. The magnetic circuit system 2 comprises a chip, a magnetic shield and magnetic steel positioned between the chip and the magnetic shield, and the voice coil 3 is connected with the magnetic steel and the vibrating diaphragm in the vibrating diaphragm assembly 4. The diaphragm assembly 4 is not limited in specific structure, and includes a diaphragm, a connecting structure for fixing the diaphragm to the bracket mechanism 1, a protective cover, and the like. The connection between the bracket mechanism 1 and the magnetic circuit system 2 is flexible connection, that is, based on flexible connection, the magnetic circuit system 2 can move relative to the bracket mechanism 1, and redundant vibration potential energy can be consumed inside the loudspeaker through the movement of the magnetic circuit system 2, so that the phenomenon of avoiding resonance is realized.
Based on the foregoing embodiment, the beneficial effects of this embodiment include simple overall structure, no significant modification to the original speaker structure, and easy implementation. And through the scheme of this embodiment can effectively reduce the vibration of speaker, avoid its and equipment casing resonance, bring the influence for user's use. In addition, as shown in fig. 4, it is known through experimental comparison that the scheme based on the embodiment also has no influence on the performance of the speaker, the frequency response is still stable, and no distortion phenomenon occurs.
Further, the connection between the bracket mechanism 1 and the magnetic circuit system 2 is achieved through a connecting piece 5 made of flexible material, and the magnetic circuit system 2 can vibrate relative to the bracket mechanism 1 based on the connecting piece 5. For example, the flexible material may be rubber, or may even be a structure having elasticity such as a spring. Based on the speakers of different structural shapes and sizes, the support mechanism 1 and the magnetic circuit system 2 can be connected through a plurality of evenly distributed connecting pieces 5, and the specific number is variable. The structure of the connecting piece 5 is not limited, and it may be annular, so as to surround the magnetic circuit system 2 and connect with the bracket mechanism 1 at the same time, or may be a plurality of linear structural members, and two ends of the connecting piece are respectively connected with the magnetic circuit system 2 and the bracket mechanism 1.
In order to enhance the vibration reduction effect, in an embodiment, the vibration direction of the magnetic circuit system 2 is opposite to the vibration direction of the diaphragm in the diaphragm assembly 4. Based on the opposite vibration direction, the vibration energy of the magnetic circuit system 2 and the vibration energy transferred to the bracket mechanism 1 by the vibration film can be offset, so that the vibration of the bracket mechanism 1 is reduced.
Preferably, in order to achieve the above-mentioned complete cancellation of the vibration energy/vibration potential energy, in another embodiment, the vibration amount of the magnetic circuit system 2 is preferably set to a state consistent with the vibration amount of the diaphragm in the diaphragm assembly 4. The flexibility of the connecting piece 5 for realizing flexible connection can be adjusted, and the effect of consistent vibration quantity can be realized by the connection mode, if the vibration quantity of the vibrating diaphragm is large, the flexibility of the connecting piece 5 is increased. And if the vibration amount of the diaphragm is small, the flexibility of the connecting piece 5 can be reduced adaptively.
Or, as in the present embodiment, a functional module 6 for adjusting the quality factor (Q value) of the magnetic circuit 2 may be provided between the magnetic circuit 2 and the bracket mechanism 1. The magnetic circuit system 2 in this embodiment has a larger mass and is significantly larger than the mass of the diaphragm and the voice coil 3, and therefore belongs to a high Q factor structure. While a high Q factor indicates a slower rate of energy loss of the vibrator, the vibration may last longer, e.g. a single pendulum moving in air with a higher Q factor, whereas a single pendulum moving in oil with a lower Q factor, i.e. a vibrator (structure) with a high Q factor is generally damped less. That is, when the magnetic circuit 2 vibrates, the vibration amount thereof is higher than that of the diaphragm and also higher than that of the voice coil 3. In order to avoid the vibration of the magnetic circuit system 2 counteracting the vibration of the excessive diaphragms, the broadcasting effect of the loudspeaker is reduced, and the performance of the loudspeaker is affected, in this embodiment, the Q factor of the magnetic circuit system 2 is adjusted, so that the quality factor of the magnetic circuit system 2 is adjusted, and then the vibration quantity is consistent with the vibration quantity of the diaphragms.
Further, since the Q factor is related to the damping of the vibrator, as shown in fig. 3, a functional module 6 for increasing the vibration damping of the magnetic circuit 2 is disposed between the magnetic circuit 2 and the bracket mechanism 1 in this embodiment, so as to reduce the vibration amount of the magnetic circuit 2 by increasing the damping of the magnetic circuit 2, so that the vibration amount is consistent with the vibration amount of the vibrating diaphragm, and further, the vibration energy transferred from the vibrating diaphragm to the voice coil 3 and the bracket mechanism 1 is counteracted.
The functional module 6 in this embodiment may be, but is not limited to, composed of one or more damping structures. For example, the damping structural member is connected to the magnetic circuit system 2, such as flexible connection, so that the vibration energy generated by the damping structural member counteracts the vibration energy of a part of the magnetic circuit system 2, or the damping structural member is simultaneously connected to the magnetic circuit system 2 and the support mechanism 1, so as to limit the movement of the magnetic circuit system 2 relative to the support mechanism 1 in any direction, and further reduce the vibration quantity of the magnetic circuit system 2, so that the vibration quantity of the magnetic circuit system is consistent with that of the vibrating diaphragm.
Another embodiment of the utility model also provides an electronic device comprising a loudspeaker as described in any of the previous embodiments. The electronic device is, for example, a notebook computer.
The above embodiments are only exemplary embodiments of the present utility model and are not intended to limit the present utility model, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this utility model will occur to those skilled in the art, and are intended to be within the spirit and scope of the utility model.
