Problems solved by technology
Such earphones need frequency division, that is, use a frequency divider to separate the sounds of different frequencies, and use two sounding units to emit sound respectively. Such earphones have a better frequency response effect, but due to the complex circuit structure, they take up a lot of space and are expensive. However, in order to reduce costs, some merchants on the market simply put together two ordinary speakers as dual-unit headphones for sale, which cannot achieve the frequency division effect required by real dual-unit headphones.

Embodiment Construction
[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0021] Such as Figure 1 to Figure 3 As shown, the embodiment of the present application proposes a dual-unit earphone with its own frequency division network, including a housing 10, and a speaker assembly 1 is provided in the housing 10, and the speaker assembly 1 connects the The space is separated to form a front chamber 2 and a rear chamber 3. The speaker assembly 1 includes a tweeter 11 close to the front chamber 2 and a woofer 12 near the rear chamber 3. Between the tweeter 11 and the woofer 12 is a A spacer cavity 4, a frequency division...

The invention relates to the technical field of electroacoustic equipment, in particular to a double-unit earphone with a frequency division network. The double-unit earphone comprises a shell, a loudspeaker assembly is arranged in the shell, the loudspeaker assembly divides the space in the shell into a front cavity and a rear cavity, and the loudspeaker assembly comprises a first loudspeaker close to the front cavity and a second loudspeaker close to the rear cavity. An interval cavity is arranged between the first loudspeaker and the second loudspeaker, and a frequency division channel communicated with the interval cavity and the front cavity is arranged between the interval cavity and the front cavity. According to the dual-unit earphone with the frequency division network, frequencydivision is realized by adopting a mechanical structure, and compared with frequency division by adopting an electronic element, the dual-unit earphone basically does not occupy extra space, is more compact and smaller in structure, and is more convenient to produce and manufacture.
Description
【Technical field】 [0001] The present application relates to the technical field of electro-acoustic equipment, in particular to a dual-unit earphone with its own frequency division network. 【Background technique】 [0002] The dual unit in the dual-unit earphone refers to a low-frequency unit and a high-frequency unit (one bass plus one treble). Commonly seen earphones and small earplugs have only one sounding unit per channel, and the dual unit is each side. There are two sounding units. Such earphones need frequency division, that is, use a frequency divider to separate the sounds of different frequencies, and use two sounding units to emit sound respectively. Such earphones have a better frequency response effect, but due to the complex circuit structure, they take up a lot of space and are expensive. However, in order to reduce costs, some merchants on the market simply put together two ordinary speakers as dual-unit headphones for sale, which cannot achieve the frequenc...
