Embodiment 1

[0023] Embodiment one, such as figure 1 As shown, an earphone with an improved structure includes a housing 1, and a housing cavity is formed inside the housing 1, and a speaker 4 is installed in the housing cavity, and the speaker 4 is connected with an audio signal transmission line 5, and the audio signal transmission line 5 It is electrically connected with the speaker 4, the accommodating cavity includes a first sound chamber 2 and a second sound chamber 3, the first sound chamber 2 is located at the front side of the speaker 4, the second sound chamber 3 is located at the rear side of the speaker 4, and the speaker 4 It is fixed on the rear end of the first sound chamber 2 , the first sound chamber 2 and the second sound chamber 3 are isolated from each other and communicate with the outside of the sound output side of the casing 1 respectively.

[0024] The loudspeaker 4 converts the electrical signal transmitted via the audio signal transmission line 5 into a sound sig...

Embodiment 2

[0027] Embodiment two, such as figure 2 As shown, the difference between the second embodiment and the first embodiment is that the front casing 11 includes a fixed sleeve 6 installed in the inner cavity of the front casing 11, and the outer peripheral wall of the fixed sleeve 6 is connected with the inner surface of the front casing 11. The surrounding wall is socketed, the fixed sleeve 6 is formed with the first sound chamber 2, and the fixed sleeve 6 is provided with a channel 61 corresponding to the second sound chamber 3, and the channel 61 communicates with the second sound chamber 3 and the corresponding sound chamber 3. Sound outlet 111. In order to ensure that the loudspeaker 4 can be stably installed in the accommodating cavity of the housing 1, the present invention uses a specific fixing sleeve 6 to install and fix the loudspeaker 4, wherein the fixing sleeve 6 is inserted into the inner cavity of the front housing 11 and The front casing 11 is socketed, and the ...

Abstract

The invention relates to the technical field of earphones, in particular to an earphone with an improved structure. The earphone comprises a shell. A holding chamber is formed in the shell. A loudspeaker is installed in the holding chamber and is connected with an audio signal transmission line. The audio signal transmission line is in electrical signal connection with the loudspeaker. The holding chamber comprises a first sound chamber and a second sound chamber, wherein the first sound chamber is arranged on the front side of the loudspeaker and the second sound chamber is arranged on the rear side of the loudspeaker. The loudspeaker is fixed at the rear end part of the first sound chamber. The first sound chamber and the second sound chamber are isolated from each other and are respectively communicated with the external part of the sound outlet side of the shell. When the earphone works, one part of sound made by the loudspeaker is transmitted out of the shell through the first sound chamber and sound outlets and the other part of the sound is transmitted out of the shell through the second sound chamber and the sound outlets, wherein the sound which enters the second sound chamber is reverberated in the second sound chamber and can compensate bass insufficiency. Thereby, the earphone has the advantages of good bass effect and strong sense of stereophonic sound.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to an earphone with improved structure. Background technique [0002] With the development and progress of information technology, various technological products are constantly entering people's daily life. In addition, these technological products are gradually affecting and changing people's lives. Wherein, the earphone is widely used in people's life as an audio output device, and has become a necessary device for various audio playback devices. [0003] With the continuous improvement of people's requirements for the quality of earphones, the basic audio output function is far from meeting people's requirements. Among them, the sound effect of earphones has been paid more and more attention by people. an important reference. The sound outlet of the earphone in the prior art is generally arranged facing the loudspeaker, that is, the sound from the loudspeaker is transmitted d...
