BACKGROUND OF INVENTION

Technology Field

This application relates to the technical field of speakers, and in particular to a speaker assembly and a speaker.

Technique of the Prior Art

Dynamic is a kind of speaker transducer. A driving mode of dynamic headphones is driven by a voice coil in a permanent magnetic field to drive the vibration of a diaphragm connected to the voice coil, so as to output sound. The voice coil inside an armature headphones is wound on a balanced armature located in the center of a permanent magnetic field, the balanced armature drives the diaphragm under the action of magnetic force to produce sound.

At present, in order to combine the respective advantages of dynamic headphones and armature headphones, coil-iron headphones combining dynamic and armature are provided. However, current coil-iron headphones usually have a separating armature unit and dynamic unit, the separation leads to a large sound wave phase difference, and reduce the sound quality of the headphones.

SUMMARY OF INVENTION

The present application provides a speaker assembly and a speaker to solve the above problems and to improve sound quality of the speaker.

In order to solve the above technical problems, the application provides a speaker assembly comprising: a first housing, an inner side wall of the first housing constitutes a first cavity; a diaphragm disposed in the first cavity, a circumference of the diaphragm is connected to the inner wall of the first housing; a voice coil disposed on one side of the diaphragm; and an armature member disposed in the first cavity, the armature member is located on a same side of the diaphragm as the voice coil.

In an embodiment of the application, a direction from the diaphragm to the armature member is a sound out direction of the speaker assembly.

In an embodiment of the present application, the speaker assembly further comprises a magnet and a second housing embedded in the first cavity, an inner side wall of the second housing forming a holding cavity. wherein the magnet, the holding cavity, and the voice coil are located on a same side of the diaphragm and are fixed in the first cavity. the second housing is provided with an opening connected to the holding cavity, the opening is oriented in the same direction as the sound out direction, at least part of the armature member is housed in the holding cavity through the opening.

In an embodiment of the present application, the magnet is a annular magnet and the holding cavity is located in a center of the annular magnet. A voice coil cavity is disposed between the inner wall of the first housing and an outer wall of the second housing, the voice coil is a ring around the holding cavity, and at least an end of the voice coil is embedded in the voice coil cavity. the voice coil cavity is formed by an inner wall of the annular magnet and an outer wall of the second housing, or formed by an outer wall of the annular magnet and the inner wall of the first housing.

In an embodiment of the present application, the annular magnet includes an outer annular magnet and an inner annular magnet. An inner wall of the inner annular magnet abuts against the outer wall of the second housing, an outer wall of the outer annular magnet abuts against the inner wall of the first housing. The voice coil cavity is formed by an inner wall of the outer annular magnet and an outer wall of the inner annular magnet.

In an embodiment of the present application, the second housing includes an extension, the extension is provided with a first through hole and the first through hole is connected to the voice coil cavity to form a first sound outlet channel.

In an embodiment of the present application, the second housing is provided with a second through hole, the second through hole communicates with the holding cavity to form a second sound outlet hole.

In an embodiment of the present application, at least part of the second housing is formed by magnetic conductor.

In an embodiment of the present application, the diaphragm comprises a recessed first membrane flap, and the holding cavity is at least partially housed in the first membrane flap.

In an embodiment of the present application, a first part, a second part axially connected to the first part, and a connector connecting the first part and the second part. A diameter of the first part is greater than a diameter of the second part. A perimeter of the diaphragm is attached to the first portion or the connector. The armature member is provided in the second part. The connector is provided with a third sound outlet hole.

In prior art, the side of the diaphragm away from the voice coil is usually designed with a protective structure such as a front cover, so it is not possible to set the armature member on the side of the diaphragm away from the voice coil, resulting in the distance between the armature member and the diaphragm cannot be further reduced. Since the distance between the diaphragm and the armature member is usually less than a minimum wavelength of audio, the greater the distance between the armature member and the diaphragm, the greater the phase difference between the output sound waves. Excessive phase differences can lead to audio separation between the sound output by the armature member and the diaphragm, reducing the sound quality of the speaker.

To overcome this problem, the application sets the voice coil and the armature member on a same side of the diaphragm, further reducing the distance between the armature member and the diaphragm. This setting can reduce the phase difference between the sound waves output by the armature member and the diaphragm, improve the phenomenon of audio separation, and thus improve the sound quality of the speaker.
