The following describes the speaker 100 provided in the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

As shown in fig. 1 to 4, a speaker 100 according to an embodiment of the present application includes a frame 10, a diaphragm system 20, a magnetic assembly 30, a voice coil 50, an air permeable member 332, a sealing member 312, and a sound absorbing material member 40.

Specifically, the frame 10 defines a receiving cavity 70 therein, and the diaphragm system 20 is disposed on a first side of the frame 10. The magnetic assembly 30 is disposed on the second side of the basin stand 10, and the magnetic assembly 30 is provided with a mounting passage 80 and a receiving groove 301 communicated with the receiving cavity 70. A portion of the voice coil 50 extends into the mounting passage 80 and defines a gap with the mounting passage 80, which communicates with the accommodating chamber 70, and the accommodating chamber 70 and the gap form an air flow passage therebetween. The air permeable member 332 is disposed on the first side of the accommodating groove 301, and the air permeable member 332 has a plurality of first air holes for communicating the accommodating cavity 70 and the accommodating groove 301. The sealing member 312 is disposed on the second side of the accommodating groove 301, the sound-absorbing material 40 is disposed on the accommodating groove 301, and the sectional area of the sound-absorbing material 40 is not smaller than the area of the first vent. In the case where the diaphragm system 20 vibrates, the sound-absorbing material piece 40 absorbs or releases the airflow introduced from the accommodating chamber 70 into the accommodating groove 301 to relieve the pressure of the airflow led out from the airflow passage.

In other words, as shown in fig. 1, the speaker 100 according to the embodiment of the present application is mainly composed of a frame 10, a diaphragm system 20, a magnetic assembly 30, a voice coil 50, a permeable member 332, a sealing member 312, and a sound-absorbing material member 40. Wherein, the both sides of basin frame 10 are equipped with vibrating diaphragm system 20 and magnetic component 30 respectively, and the vibrating diaphragm is located vibrating diaphragm system 20 and is including the vibrating diaphragm, and speaker 100 during operation, the vibrating diaphragm can vibrate. The basin stand 10 defines an accommodating cavity 70 therein, and the magnetic assembly 30 is provided therein with a mounting passage 80 and an accommodating groove 301, the mounting passage 80 and the accommodating groove 301 being in communication with the accommodating cavity 70. The voice coil 50 is disposed on a side of the frame 10 facing the magnetic assembly 30, and a portion of the voice coil 50 can protrude into the mounting passage 80. And the portion of the voice coil 50 extending into the mounting passage 80 can form a gap with the mounting passage 80, the gap communicates with the accommodating chamber 70 to form an air flow passage, and air in the speaker 100 can flow in the air flow passage and the accommodating chamber 301. An air permeable member 332 is provided at the first side of the receiving groove 301 to close the opening of the first side of the receiving groove 301. The air permeable member 332 has a plurality of first air holes communicated with the accommodating cavity 70 and the accommodating groove 301, and the air inside the accommodating groove 301 can flow out from the first air holes. A sealing member 312 is provided at the second side of the receiving groove 301 to close the opening of the second side of the receiving groove 301.

The sound-absorbing material piece 40 is arranged in the accommodating groove 301, and the sectional area of the material in the sound-absorbing material piece 40 is not smaller than the area of the first air holes. The air permeable member 332 is capable of allowing air to pass through, and preventing the sound-absorbing material 40 from passing through the first air permeable hole and entering the interior of the speaker 100 to interfere with the diaphragm and collide with the diaphragm to generate noise. When the diaphragm system 20 vibrates, the air in the accommodating chamber 70 vibrates to form an air flow, and flows into the accommodating chamber 301. The sound-absorbing material 40 can absorb or release the air flow guided into the receiving groove 301 from the receiving cavity 70, and can relieve the pressure of the air flow guided out from the air flow channel, so that the air flow is more smooth, and the distortion problem of the loudspeaker 100 is improved.

The speaker 100 of the prior art improves the low frequency performance of the micro-speaker 100 by increasing the amplitude of the speaker 100, thereby increasing the loudness of the released sound. As the amplitude of the loudspeaker 100 increases, the cavity required for its vibration increases, i.e., the space defined between the voice coil 50, the diaphragm, and the magnetic conductive plate increases. However, due to the volume of the speaker 100, the gap between the voice coil 50 and the magnetic conductive plate is not increased, and even the gap is smaller under the process requirement of the small-sized speaker 100.

Therefore, the air in the space defined between the voice coil 50, the diaphragm and the magnetic conductive sheet cannot be smoothly discharged from the gap, which results in unsmooth air circulation in the cavity, and further results in distortion of the speaker 100 and even air flow noise.

The working principle of the loudspeaker 100 of the present application is:

when the diaphragm system 20 vibrates, the cavity (the accommodating chamber 70) inside the speaker 100 is squeezed or stretched, and an air flow is formed in the cavity and needs to be guided out from the air flow channel. Since the housing groove 301 communicates with the mounting passage 80 and the housing chamber 70, the sound-absorbing material piece 40 is provided inside the housing groove 301. The sound-absorbing material piece 40 can play a role in temporarily storing or releasing air, air flow can not be very rapid when circulating from the gap, air flow in the air flow channel can smoothly circulate, and the problems of distortion and air flow noise caused by unsmooth air flow of the large-amplitude loudspeaker 100 can be solved. And the ventilation hole is arranged on the ventilation member 332 which closes the opening of the accommodating groove 301 in the direction close to the diaphragm system 20, so that the smooth flow of the air in the whole cavity of the loudspeaker 100 is further ensured. Therefore, it can ensure that the sound is not distorted while ensuring the loudness performance of the speaker 100. Since the sound absorbing material 40 is provided inside the speaker 100, the speaker 100 can be pushed more easily in an operating state, and power consumption of the speaker 100 can be reduced in use.

Note that the sound-absorbing material piece 40 is composed of a suction material, and the sound-absorbing material can function to temporarily store or release air. The sound absorbing material has various types, and different types of sound absorbing materials can achieve different sound absorbing effects. When the diaphragm vibrates, the space in the cavity may be compressed, the gas in the accommodating chamber 70 is compressed, and the sound-absorbing material 40 may absorb a portion of the air. Or when the diaphragm vibrates, the sound-absorbing material 40 can release a part of air to ensure smooth air circulation when the space in the accommodating cavity 70 is expanded outwards.

Thus, according to the speaker 100 of the embodiment of the present application, by providing the accommodation groove 301 communicating with the accommodation cavity 70 and the installation passage 80 in the magnetic assembly 30, the sound-absorbing material 40 is provided in the accommodation groove 301, and the problem of the unsmooth air circulation inside the speaker 100 can be solved. When the diaphragm vibrates, the sound-absorbing material 40 can absorb or release the airflow guided into the accommodating groove 301 by the accommodating cavity 70, and can relieve the pressure of the airflow guided out from the airflow channel, so that the airflow is smoothly guided out from the airflow channel, and the distortion problem of the loudspeaker 100 is solved. The loudspeaker 100 of the present application can ensure that the sound is not distorted while ensuring the loudness performance of the loudspeaker 100, and the loudspeaker 100 has low energy consumption.
