The main cavity 111 is located between the cover connection end 110a and the base connection end 110b. The main cavity 111 is exposed on the cover connection end 110a. The moving coil installation cavity 112 and the moving iron installation cavity 113 are respectively communicated with the side part of the main cavity 111. The moving coil installation cavity 112 and the moving iron installation cavity 113 are respectively located inside the sound outlet 110c;

[0041] Moving coil speaker 120, the moving coil speaker 120 is inserted into the moving coil installation cavity 112. A moving coil sound outlet pipe 121 is arranged inside the sound outlet 110c. The moving coil sound outlet pipe 121 communicates the bottom of the moving coil installation cavity 112 and the nozzle opening 110c1 of the sound outlet 110c;

[0042] The armature loudspeaker 130 is inserted into the armature installation cavity 113. An armature sound outlet pipe 131 is arranged inside the sound outlet nozzle 110c. The armature sound outlet pipe 131 communicates with the bottom of the armature installation cavity 113 and the nozzle opening 110c1 of the sound outlet nozzle 110c, and the armature sound outlet pipe 131 and the moving coil sound outlet pipe 121 are separated from each other.

[0043] The battery 140 is fixed to the bottom of the main cavity 111.

[0044] The control board 150 is located inside the main cavity 111 and above the battery 140. The control board 150 is electrically connected to the moving coil loudspeaker 120, the armature loudspeaker 130, and the battery 140 respectively.

[0045] The moving coil loudspeaker 120, the armature loudspeaker 130, the battery 140, and the control board 150 are integrally installed inside the housing 110. The housing 110 provides the main cavity 111 for accommodating the battery 140 and the control board 150, the moving coil installation cavity 112 for accommodating the moving coil loudspeaker 120, and the armature installation cavity 113 for accommodating the armature loudspeaker 130, with good fixing effect and improved stability of the headphone sound quality. In addition, the moving coil installation cavity 112 and the armature installation cavity 113 communicate with the side of the main cavity 111 in an inclined manner, making rational use of the internal structure of the housing 110, facilitating the electrical connection of the control board 150 to the moving coil loudspeaker 120, the armature loudspeaker 130, and the battery 140 respectively, and reducing the volume.

[0046] The housing 110 is integrally injection-molded, simultaneously forming the main cavity 111, the moving coil installation cavity 112, the armature installation cavity 113, as well as the moving coil sound outlet pipe 121 and the armature sound outlet pipe 131.

[0047] As Figure 3 shown, the main cavity 111 includes a bottom and a side. One end of the side of the main cavity 111 is closed by the bottom of the main cavity 111, and the other end of the side of the main cavity 111 is exposed at the cover connection end 110a, so that the moving coil loudspeaker 120, the armature loudspeaker 130, the battery 140, and the control board 150 are placed inside the housing 110 through the cover connection end 110a.

[0048] Refer to Figures 1 to 3The battery 140 abuts against and is limited on the bottom of the main cavity 111. Specifically, a battery installation groove 111a and a limit block 111b are provided on the bottom of the main cavity 111. The bottom of the battery 140 is embedded in the battery installation groove 111a, and the battery 140 is limited and fixed by the limit block 111b to prevent the battery 140 from rotating, thereby improving the stability of the installation of the battery 140. A groove is provided on the surface of the battery 140, and the groove cooperates with the limit block 111b to prevent the battery 140 from rotating.

[0049] refer to Figures 1 to 3 The control board 150 is located above the battery 140 and can be fixedly abutted against the side of the main cavity 111. Specifically, a control board step 111c is provided on the side of the main cavity 111, and the control board 150 abuts against the control board step 111c. Figure 5 After the cover assembly 300 is buckled with the cover connecting end 110 a of the housing 110 , the control board 150 is limited between the control board step 111 c and the cover assembly 300 .

[0050] refer to Figure 1 and Figure 3 , the module 100 further includes:

[0051] The antenna seat 160 is snapped onto the side of the main cavity 111, one end of the antenna seat 160 is located inside the main cavity 111, and the other end of the antenna seat 160 is located outside the shell 110. The antenna seat 160 is electrically connected to the control board 150, and the antenna seat 160 is located above the battery 140.

[0052] The antenna base 160 (ie, MMCX interface) is a coaxial radio frequency connector that can be used on in-ear headphones to ensure stable signal transmission. The antenna base 160 is clamped on the side of the main cavity 111.

[0053] Furthermore, an antenna fixing block 110d is provided on the side of the main cavity 111, the antenna seat 160 is clamped inside the antenna fixing block 110d, and the control board 150 avoids the antenna seat 160 and abuts against the antenna fixing block 110d. The antenna seat 160 may be cylindrical, and the upper part of the antenna fixing block 110 is recessed downward to form a semicircular groove, that is, the antenna seat 160 is placed in the semicircular groove from the upper part of the antenna fixing block 110, and the control board 150 avoids the antenna seat 160 and abuts against the upper part of the antenna fixing block 110. It can be seen that the control board 150 is abutted and fixed on the control board step 111c and the antenna fixing block 110 at the same time.

[0054] As Figures 1 to 4 shown, the battery 140 provides electrical energy for the operation of the control board 150 and the like. The control board 150 transmits signals through the antenna base 160, and can emit low and medium audio frequencies, as well as part of the high audio frequency, through the moving coil loudspeaker 120, and emit high audio frequencies through the moving iron loudspeaker 130. The mouth 110c1 of the sound outlet 110c is correspondingly placed in the user's ear. That is, the audio emitted by the moving coil loudspeaker 120 is transmitted to the mouth 110c1 of the sound outlet 110c through the moving coil sound outlet tube 121, and the audio emitted by the moving iron loudspeaker 130 is transmitted to the mouth 110c1 of the sound outlet 110c through the moving iron sound outlet tube 131. The moving iron sound outlet tube 131 and the moving coil sound outlet tube 121 are separated from each other, that is, they are not connected and are independent of each other, and converge at the mouth 110c1 of the sound outlet 110c and are transmitted into the user's ear.

[0055] Refer to Figure 3 and Figure 4 , an air leakage installation hole 110e is provided on the side of the main cavity 111, and an air leakage tube 122 is further provided in the housing 110. One end of the air leakage tube 122 is communicated with the moving coil sound outlet tube 121, and the other end of the air leakage tube 122 is communicated with the air leakage installation hole 110e. By providing the air leakage tube 122, the pressure balance can be ensured, heat dissipation can be facilitated, and the sound quality can be improved. The air leakage installation hole 110e is located above the moving coil installation cavity 112 and the moving iron installation cavity 113.

[0056] As Figure 1 and Figure 2 shown, the cover connection end 110a and the base connection end 110b are substantially horizontal planes, and the outer side surface of the housing 110 connected between the cover connection end 110a and the base connection end 110b is a curved surface. The base connection end 110b bulges towards the cover connection end 110a to form the sound outlet 110c. The cross-section of the sound outlet 110c gradually decreases from the base connection end 110b to the mouth 110c1 direction, and the whole sound outlet 110c is inclined relative to the base connection end 110b.

[0057] It can be seen that the included angle between the axis of the moving coil installation cavity 112 and the axis of the main cavity 111 is 15° to 45°; the included angle between the axis of the moving iron installation cavity 113 and the axis of the main cavity 111 is 15° to 45°. That is, the moving coil loudspeaker 120 and the moving iron loudspeaker 130 are adaptively installed inside the sound outlet 110c.

[0058] In summary, the moving coil loudspeaker 120, the armature loudspeaker 130, the battery 140, and the control board 150 are integrally installed inside the housing 110. The housing 110 provides a main cavity 111 for accommodating the battery 140 and the control board 150, a moving coil installation cavity 112 for accommodating the moving coil loudspeaker 120, and an armature installation cavity 113 for accommodating the armature loudspeaker 130. The fixing effect is good, and the stability of the headphone sound quality is improved. In addition, the moving coil installation cavity 112 and the armature installation cavity 113 are communicated with the side part of the main cavity 111 in an inclined manner, making reasonable use of the internal structure of the housing 110, facilitating the electrical connection of the control board 150 to the moving coil loudspeaker 120, the armature loudspeaker 130, and the battery 140 respectively, and reducing the volume.

[0059] Second Embodiment

[0060] As Figure 5 shown, the headphone includes the module 100 of the first embodiment, and the headphone further includes:

[0061] A base 200, which is inserted into the base connection end 110b of the housing 110, and the sound outlet nozzle 110c is embedded inside the base 200;

[0062] A cover assembly 300, which is snap - connected to the cover connection end 110a of the housing 110.

[0063] One side of the base 200 away from the module 100 can be connected to an earplug head for being inserted into the user's ear, that is, the cover assembly 300 is arranged outward.

[0064] The base connection end 110b of the housing 110 is adaptively connected to the inner side surface of the base 200. The sound outlet nozzle 110c on the base connection end 110b is embedded in the inner side surface of the base 200 and corresponds to the earplug connecting tube 201 on the outer side surface of the base 200. In this way, after an earplug head is connected to the earplug connecting tube 201 and the earplug head is placed in the user's ear, due to the correspondence between the sound outlet nozzle 110c and the earplug connecting tube 201, the user can hear clear sound.

[0065] As Figure 1 、 2 、5 shown, in addition to part of the protrusion on the base connection end 110b forming the sound outlet nozzle 110c, an insertion block 110b1 is also provided on the base connection end 110b. A jack 202 is formed on the inner side surface of the base 200. By inserting the insertion block 110b1 into the jack 202 and embedding the sound outlet nozzle 110c on the inner side surface of the base 200, the insertion and fixation of the base 200 to the housing 110 are realized.

[0066] Since the base connection end 110b of the base 200 and the housing 110 is detachably connected by means of plugging, different-shaped and patterned bases 200 can be selected for replacement as needed.

[0067] As Figure 5 shown, the cover assembly 300 includes:

[0068] a replaceable cover 320;

[0069] an inner cover 310, one side of the inner cover 310 is snap-connected to the cover connection end 110a, and the other side of the inner cover 310 is detachably connected to the replaceable cover 320.

[0070] The inner cover 310 can be snap-connected to the cover connection end 110a of the housing 110 and fixed by glue for reinforcement. That is, the inner cover 310 and the module 100 can be regarded as a whole to be assembled with the replaceable cover 320 and the base 200. Since the replaceable cover 320 and the inner cover 310 are detachably connected, different appearances such as different patterns and different decorative effects can be obtained by replacing the replaceable cover 320.

[0071] Taking the snap connection as an example for the detachable connection, the replaceable cover 320 is provided with a snap hole 321, and the inner cover 310 is provided with a snap strip 311. The snap strip 311 is in an L shape. When the front end of the snap strip 311 can be made of an elastic material, that is, after the front end of the snap strip 311 is deformed and passes through the snap hole 321, the front end of the snap strip 311 is reset and abuts against the outer side surface of the replaceable cover 320. Since the front end of the snap strip 311 is made of an elastic material, the replaceable cover 320 can be pulled relative to the inner cover 310, and then the snap strip 311 is disengaged from the snap hole 321 to achieve the detachable connection between the replaceable cover 320 and the inner cover 310.

[0072] The above-described embodiments are only used to illustrate the technical idea and characteristics of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The scope of the patent adoption of the present invention cannot be limited only by this embodiment.
