Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, embodiments of the present invention are described in detail below, and the embodiments of the present invention are described in detail below clearly and completely.

The terminology used herein is for the purpose of explaining the embodiments and is not intended to limit and/or define the invention.

For example, expressions such as "in a certain direction", "along a certain direction", "parallel", "orthogonal", "center", "relative", "front-back-left-right" and the like indicate relative or absolute arrangements, and indicate not only such arrangements in a strict sense but also a state of being relatively displaced with a tolerance or an angle or a distance to the extent that the same function can be obtained.

As shown in fig. 1, the high heat dissipation sound generator mainly includes a magnetic magnet 10, a sound film 20 and a voice coil 30, and combines a magnetic cover 13 and a support body 70 to form a speaker structure, where the magnet 10 is composed of stacked magnetic steel 11 and pole pieces 12, specifically, the support body 70 is used as a basic frame, the magnetic steel 11, the pole pieces 12 and the magnetic cover 13 are combined to provide a magnetic field, the voice coil 20 is energized, and receives a magnetic field force in the magnetic field to bring the sound film to vibrate to push air to make sound.

The voice coil 30 is connected to the globe top 21, and the rim 22 is connected to the yoke body 70.

Wherein, at least one air hole 50 is opened on the sound film 20, it is sufficient that this air hole 50 is generally located on the ball top 21, of course, also can position limit portion 22 position, it can also be that all set up air hole 50 on ball top 21 and limit portion 22, through air hole 50, because the sound film, the voice coil loudspeaker voice coil, the magnetic fluid, the pole piece forms the inner space, the air hole on the sound film can realize that inside air and outside air communicate, during speaker work, the ball top vibrates from top to bottom, promote inside and outside circulation of air, the heat that the voice coil loudspeaker voice coil produced can circulate along with the inside and outside world of air, and directly disperse in the outside air fast, and, besides, air hole 50 is except conveniently conducting heat, also can make the sound film, the voice coil loudspeaker voice coil, the magnetic fluid, the pole piece form inner space and keep balance with outside atmospheric pressure, avoid the unable discharge of inner space air, influence the distortion performance of speaker.

Meanwhile, in order to prevent dust from entering the interior through the air holes 50, the surface of the air holes 50 is selectively covered with the breathable layer 60, and the breathable layer 60 adopts a breathable mesh fabric structure, so that the dust can be prevented from entering the interior space, and the working life of the loudspeaker is prevented from being influenced; and airflow disturbance sound caused by air circulation can be eliminated, and influence on the hearing of a client is avoided.

Wherein, voice coil 30 is connected with voice coil membrane 20 and is located the below position of voice coil membrane 20, this voice coil 30 encircles magnet 10 and sets up, and it is provided with heat conductor 40 to fill between magnet 10 and voice coil 30, heat conductor 40 adopts the magnetism liquid here, the speaker during operation, the heat that the voice coil produced can conduct on the magnetism liquid, because magnetism liquid possess than the faster heat conductivility of air, can be fast with heat conduction pole piece, the rethread pole piece conducts the heat to shell departments such as magnet steel, magnetism cover and stake body in proper order, realize high-efficient heat dissipation.

In order to ensure the heat conduction effect, the heat conductor 40 is disposed around the magnet 10 and contacts with the voice coil 30, specifically, the heat conductor 40 may be only located around the pole piece 12 or the magnetic steel 11, and of course, may also be located around the pole piece 12 and the magnetic steel 11.

Meanwhile, an electronic product comprising the high-heat-dissipation sounder is also provided, such as a watch, a mobile phone and the like.
