Description

Headset structure with passive vibrating diaphragm

Technical Field

The invention belongs to the technical field of earphone structures, and relates to a headset structure with a passive diaphragm.

Background

The passive diaphragm is also called a passive radiator, and is commonly arranged in a sound box of a loudspeaker together with the loudspeaker unit, and the loudspeaker unit and the passive diaphragm share a back cavity, so that when the loudspeaker unit sounds, air compressed by the loudspeaker unit in the back cavity is transmitted to the passive diaphragm, and then the passive diaphragm is indirectly driven to sound.

Therefore, for the loudspeaker with smaller back cavity volume, the resonance effect of the back cavity can be enhanced by the aid of the passive vibrating diaphragm, and the overall sound field performance of the loudspeaker is optimized. The application of the passive vibrating diaphragm is also extended to the field of earphones at present, but the passive vibrating diaphragm is generally directly arranged in a sound generating unit of the earphone due to the volume limitation of the earphone structure; the vibrating area of the passive diaphragm is limited, the volume of the air which can be pushed is limited, and the resonance and bass diving effects are limited.

Referring to fig. 1 to 2, in an embodiment of the present invention, a headphone structure with a passive diaphragm 5 includes: a pair of headphone assemblies 1, each headphone assembly 1 including an outer housing 3, and a headphone sound generating unit 4 disposed within the outer housing 3; an earphone head band 2 is provided between the outer cases 3 of the two headphone assemblies 1, and is formed to be curved in the length direction, and both ends of the earphone head band 2 are respectively inserted into the outer cases 3 of the two headphone assemblies 1;

the outer shell 3 is assembled by an earmuff shell 31 and an outer shell 32, and the earphone sounding unit 4 is fixedly arranged in the earmuff shell 31; the outer cover shell 32 is provided with a vibrating diaphragm 5, and the vibrating diaphragm 5 is adhered to the position of the earphone sounding unit 4;

when the earphone sound generating unit 4 vibrates to generate sound, vibration audio transmitted from the head-mounted earphone assembly 1 is transmitted to the diaphragm 5, so that the diaphragm 5 follows the vibration audio, namely, the rhythm of music audio, to vibrate at a regular rate, and the movement of the diaphragm 5 can lead to the air in the outer shell 3 to be compressed and expanded, thereby realizing the bass effect.

Compared with the traditional earphone in which the vibrating diaphragm structure is arranged in the sounding unit, in the embodiment, the vibrating diaphragm 5 structure is arranged on the outer shell 3, so that the vibrating area of the vibrating diaphragm 5 is greatly increased, the volume of the pushed air is also increased, the texture of bass is greatly improved, meanwhile, the caliber of the vibrating diaphragm 5 is increased, the frequency of a resonance product of the vibrating diaphragm is reduced, and the earphone obtains better bass submergence depth when sounding; therefore, under the condition that the earphone structure is limited in size, a good bass effect can be obtained.

In order to enable the diaphragm 5 to generate better bass effect, the diaphragm 5 is made of flexible material, wherein the diaphragm 5 is preferably made of soft silica gel material.

In order to achieve a larger diaphragm 5 area, the diaphragm 5 is arranged at the end face of the outer cover shell 32 and is arranged in parallel with the earphone sounding unit 4;

correspondingly, a through groove for mounting the diaphragm 5 is formed in the end face position of the outer cover shell 32, and the inner edge of the through groove is bent to form a step surface 322;

the diaphragm 5 includes: a fixing ring 52, a folding ring 51, and a vibrating piece 53; the fixed ring 52 is stuck on the step surface 322 of the through groove to fix the diaphragm 5 in the through groove of the outer cover shell 32, and in order to avoid glue overflow, a glue dispensing ring groove 321 which is arranged around the through groove is formed on the step surface 322 formed in the through groove;

the vibration plate 53 is connected with the fixing ring 52 into a whole through the folding ring 51, the cross section of the folding ring 51 is of an arch structure, the vibration plate 53 has good deformation characteristics, and when vibration audio is transmitted to the vibration plate 53, the vibration plate 53 generates a vibration effect through deformation and recovery actions of the folding ring 51.

In practice, the resonance frequency of the diaphragm 5 can be adjusted by adjusting the weight of the diaphragm 53, thereby providing better visual enjoyment to the user.
