3. The loudspeaker apparatus of claim 1 , wherein the housing includes an outer sidewall away from the head of the human and a peripheral sidewall connected to the outer sidewall, and the outer sidewall is surrounded by the peripheral sidewall.

4. The loudspeaker apparatus of claim 3 , wherein

the peripheral sidewall includes a first peripheral sidewall disposed along a length direction of the outer sidewall and a second peripheral sidewall disposed along a width direction of the outer sidewall; and

the outer sidewall and the peripheral sidewall are connected to form a cavity that is open at one end and accommodates the earphones core.

5. The loudspeaker apparatus of claim 4 , wherein the key module of the at least one key module is located at a middle position of the outer sidewall, or located between the middle position and a top position of the outer sidewall.

6. The loudspeaker apparatus of claim 5 , wherein the at least one key module includes a key and an elastic socket for supporting the key; and

a key hole is disposed on the outer sidewall, and the key hole cooperates with the key.

7. The loudspeaker apparatus of claim 1 , wherein a connecting part between the support connector and the housing has a central axis,

an extension line of the central axis has a projection on a plane on which an outer side surface of the key module of the at least one key module is located, and

an included angle between the projection and a long axis direction of the key module is less than 10°.

8. The loudspeaker apparatus of claim 7 , wherein the long axis direction and a short axis direction of the outer side surface of the key module have an intersection,

the projection and the intersection have a shortest distance, and

the shortest distance is less than a size of the outer side surface of the key module in the short axis direction.

9. The loudspeaker apparatus of claim 1 , wherein a center of the key module of the at least one key module and the at least one contact point have a first distance;

a center of the housing and the at least one contact point have a second distance; and

a ratio of the first distance to the second distance is not greater than 0.95.

10. The loudspeaker apparatus of claim 3 , wherein the earphone core at least includes a composite vibration component composed of a vibration board and a second vibration conductive plate, and the composite vibration component generates the two resonance peaks.

11. The loudspeaker apparatus of claim 10 , wherein the earphone core further includes at least one voice coil and at least one magnetic circuit system; and

the at least one voice coil is physically connected to the vibration board, and the at least one magnetic circuit system is physically connected to the second vibration conductive plate.

12. The loudspeaker apparatus of claim 10 , wherein a stiffness coefficient of the vibration board is greater than a stiffness coefficient of the second vibration conductive plate.

13. The loudspeaker apparatus of claim 10 , wherein the earphone core further includes a first vibration conductive plate; wherein

the first vibration conductive plate is physically connected to the composite vibration component;

the first vibration conductive plate is physically connected to the housing; and

the first vibration conductive plate generates another resonance peak.

14. The loudspeaker apparatus of claim 10 , wherein the housing further includes at least one contact area, and the contact area is at least partially in contact with a user directly or indirectly; wherein

the contact area has a gradient structure so that a pressure distribution on the contact area is uniform.

15. The loudspeaker apparatus of claim 3 , wherein the housing further includes at least one contact area, and the at least one contact area is at least partially in contact with a user directly or indirectly; wherein

the contact area includes at least a first contact area region and a second contact area region, and the second contact area region is higher than the first contact area region.

16. The loudspeaker apparatus of claim 3 , wherein at least a part of the housing is disposed with at least one sounding hole, and the at least one sounding hole leads out a sound wave in the housing, the sound wave lead out from the at least one sounding hole is superimposed with a sound wave of a leaked sound generated by a vibration of the housing to reduce the leaked sound.

17. The loudspeaker apparatus of claim 1 , wherein the at least one loudspeaker component further includes an auxiliary key module configured to supplement a function of the at least one key module.

18. The loudspeaker apparatus of claim 1 , wherein the at least one loudspeaker component further includes a voice control system configured to receive and execute voice control instructions.

19. The loudspeaker apparatus of claim 1 , further including an indicator lamp; wherein

the indicator lamp is located on the housing or the support connector, and is configured to display a status of the at least one loudspeaker component.
