Description of the embodiments

The terminology used in the description of the embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the description of embodiments of the application as set forth below in connection with the accompanying drawings.

With the development of electronic technology, electronic devices are indispensable in daily life, and speakers (such as a moving coil speaker, a piezoelectric speaker, or other external devices) are an indispensable component of electronic devices, where a speaker is a transducer (transducer) for converting electric energy into acoustic energy, specifically, converting an electric signal of an amplifier into mechanical vibration of a diaphragm, so that surrounding air generates a change in density to convert acoustic waves into sound.

Embodiments of the present application provide an electronic device, including, but not limited to, a mobile or fixed terminal with a speaker, such as a notebook, a mobile phone, a tablet, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a handheld computer, an intercom, a netbook, a POS, a personal digital assistant (personal digital assistant, PDA), a tachograph, a wearable device, a virtual reality device, a bluetooth sound/headset, or a vehicle front-mounted device.

In some embodiments, the speaker assembly includes a main frame disposed within the speaker assembly, the main frame including at least one sound emitting component thereon, at least one of a top or bottom of the main frame being provided with a magnetic component for suspending the main frame during operation, wherein the magnetic component is configured to generate a force in opposition to a gravitational force experienced by the main frame.

The magnetic component comprises a first magnetic component arranged on the sound generating component and a second magnetic component arranged at the top or bottom of the loudspeaker assembly, and the first magnetic component and the second magnetic component generate a force opposite to gravity when in operation so that the main frame is suspended inside the loudspeaker assembly. That is, when the second magnetic part is disposed at the bottom of the speaker, the first magnetic part and the second magnetic part should have repulsive force to overcome the effect of gravity; when the second magnetic part is arranged on top of the loudspeaker, the first magnetic part and the second magnetic part should be attractive to overcome the effect of gravity.

In some embodiments, the direction of the force generated by the sound generating component relative to the housing of the electronic device when the speaker assembly is in operation is opposite to the direction of the opposing force generated by the magnetic component relative to the sound generating component. The loudspeaker assembly can greatly offset the reverse force generated by the loudspeaker assembly relative to the shell of the electronic equipment, the output force of the loudspeaker assembly to the electronic equipment in the working process can be effectively reduced, the noise problem of the electronic equipment can be reduced or avoided, the conversation effect and the external sound quality of the electronic equipment are improved, and the experience of a user can be improved to a certain extent.

In some embodiments, the magnetic force of the magnetic component is configured to be adjusted according to at least one of a tempo, a volume, and a frequency of the audio being played. That is, the magnetic force of the magnetic member is adjustable, and when the rhythm of the played music is strong or the volume is large, the vibration amplitude of the main frame is larger, and at this time, the main frame can be controlled to suspend at a higher position (when the sound generating member faces the top surface) so as to maximize the movement space of the sound generating member, and of course, it is understood that when the sound generating member faces the bottom surface, the main frame should be controlled to suspend at a higher position (when the sound generating member faces the bottom surface), and at this time, the movement space of the speaker is larger.

When the main frame is suspended, the main frame may be moved due to vibration of the sound emitting part, so that the main frame gradually deviates from a predetermined set position. In some embodiments, the main frame may also cause a positional deviation when switching between levitation and suspension. In order to prevent the deviation of the main frame, a fixing slot for preventing the deviation of the position of the main frame is provided around the main frame.

To reduce the size of the speaker assembly, the fixing slot may include a plurality of sidewalls connected in series. The fixing slot may cooperate with a component of the electronic device to define a space for movement of the main frame. For example, the fixing slot can be matched with the top shell and the bottom shell of the electronic equipment to form a space for the main frame to move, and the fixing slot forms a side wall.

In some embodiments, the inner wall of the fixing slot facing the main frame is further coated with a magnetic material, and the fixing slot provided with the magnetic material can form repulsive force on the main frame, so that the main frame is prevented from sounding collision with the fixing slot in the suspension process, damage to the main frame is avoided, and service life of the loudspeaker assembly is prolonged.

In the present embodiment, the first magnetic part of the speaker is provided on the sound emitting part, and the second magnetic part 2 of the speaker is provided on the top case 4 of the notebook computer. The first magnetic part and the second magnetic part 2 attract each other to provide the main frame with an attractive force against gravity.

It should be noted that the material of the fixing socket 3 includes, but is not limited to, the above-mentioned materials. In addition, the keyboard assembly and the housing may be made of metal or plastic, which is not limited in the embodiment of the present application.

In some embodiments, the fixing slot 3 and the top housing 4 may be connected in a non-detachable manner, for example, when the fixing slot 3 is made of metal, the two may be connected by welding.

In some embodiments, the inner wall of the fixing slot 3 facing the main frame 1 is further coated with a magnetic material, and the fixing slot 3 provided with the magnetic material forms a repulsive force to the main frame 1, so that the main frame 1 is prevented from sounding collision with the fixing slot 3 in the suspension process, the damage of the main frame 1 is avoided, and the service life of the loudspeaker assembly is prolonged.

Moreover, in the embodiment of the present application, the shape and the length of the fixing slot 3 may be flexibly adjusted according to the requirements of the actual application scenario, specifically, in the actual use, the length of the fixing slot 3 may be set according to the actual size of the speaker assembly, and the shape of the fixing slot 3 is determined according to the position and the shape of the adjacent element.
