The wristwatch in the present embodiment is particularly a wristwatch having a call function.

Referring to fig. 1 and 2, the wristwatch includes a wristwatch body 10 and a band 20, the wristwatch body 10 includes a case 11, and a cavity enclosed inside the case 11 is used for mounting a speaker, a microphone, a circuit board, a battery, a motor and other related components.

The speaker 30 has a speaker sound outlet hole 31 and a speaker rear sound hole 32, and the speaker sound outlet hole 31 and the speaker rear sound hole 32 are disposed opposite to each other. The speaker sound outlet hole 31 faces the outside of the housing 11, and the speaker rear sound hole 32 faces the inside of the housing 11. The speaker sound outlet hole 31 emits sound waves to the outside of the housing 11, and the speaker rear sound hole 32 also emits sound waves.

The watch in this embodiment further includes an inverter tube 40 disposed in the case 11, the inverter tube 40 having a sound wave transmission section 43, one end of the sound wave transmission section 43 being provided with an inverter tube sound inlet hole 41, the other end of the sound wave transmission section 43 being provided with an inverter tube sound outlet hole 42, the inverter tube sound inlet hole 41 and the inverter tube sound outlet hole 42 being communicated with each other.

The inverter sound inlet hole 41 and the speaker rear sound hole 32 are located on the same side of the speaker 30, and the inverter sound inlet hole 41 faces the speaker 30. The inverter tube sound outlet 42 is directed toward the outside of the housing 11 so as to emit sound waves toward the outside of the housing 11.

The sound waves emitted by the sound hole 32 behind the loudspeaker are collected by the sound inlet hole 41 of the inverter tube, the collected sound waves are transmitted to the sound outlet hole 42 of the inverter tube along the sound wave transmission section 43, in the transmission process of the sound waves, sound wave signals with the same phase are mutually superposed to realize signal enhancement, and the vibration amplitude of the sound wave signals with the low frequency band is enhanced. The enhanced low band acoustic signal is emitted from the inverter tube outlet 42.

The acoustic wave signal emitted from the speaker sound outlet hole 31 is set as shown in fig. 4, and the acoustic wave signal emitted from the speaker rear sound hole 32 is set as shown in fig. 5. The sound wave emitted from the rear sound hole 32 of the speaker enters the sound wave transmission section 43 through the inverter tube sound inlet hole 41, and then is emitted to the outside of the housing 11 through the inverter tube sound outlet hole 42, and the sound wave signal emitted from the inverter tube sound outlet hole 42 is as shown in fig. 4.

This application collects the utilization through the sound wave that inverted tube 40 sent sound hole 32 behind the speaker for the sound wave that speaker sound outlet 31 sent and the sound wave that inverted tube sound outlet 42 sent can superpose and strengthen the bass acoustic signal in the casing 11 outside, make the sound wave signal vibration range of low-frequency range obtain the reinforcing, and then improve the acoustic effect of wrist-watch, improve user's use and experience.

In some embodiments of the present application, referring to fig. 2 and 3, the speaker sound outlet 31 and the inverter sound outlet 42 are located on the same side of the housing 11.

Thus, the sound wave emitted from the speaker sound outlet 31 and the sound wave emitted from the inverter tube sound outlet 42 can be maximally superposed outside the shell 11, so that the vibration amplitude of the sound wave signal in the low frequency band is maximized, and the acoustic effect of the watch is optimized.

In some embodiments of the present application, the diameter of the sound inlet 41 of the inverter tube is gradually reduced along the sound outlet direction of the rear sound hole 32 of the speaker. That is, the inverter tube sound inlet hole 41 is shaped like a bell mouth, which is directed toward the speaker rear sound hole 32. The bell-mouth shaped inverter tube sound inlet 41 further facilitates the collection of sound.

In some embodiments of the present application, the diameter of the inlet end of the inverter sound inlet hole 41 is not smaller than the outer diameter of the speaker rear sound hole 32, so that the inverter sound inlet hole 41 can more effectively collect the sound emitted from the speaker rear sound hole 32.

In some embodiments of the present application, the diameter D1 of the sound wave transmission section 43 is smaller than the diameter D2 of the speaker 30, so that the sound waves emitted from the rear sound hole 32 of the speaker can be further enhanced in the sound wave transmission section 43, and the bass sound quality can be improved.

In some embodiments of the present application, no device (including a microphone, a circuit board, a battery, a motor, etc.) is installed between the speaker rear sound hole 32 and the inverter tube sound inlet hole 41. That is, the area between the rear sound hole 32 of the speaker and the sound inlet hole 41 of the inverter tube is a vacant area to prevent the device from blocking the collection of the sound wave signal, and to ensure that the sound wave emitted from the rear sound hole 32 of the speaker can enter the inverter tube 40 without blocking.

In some embodiments of the present application, the watch also has a pressure relief vent (not labeled), and the inverter sound outlet 42 is the same vent as the pressure relief vent. The phase inverter tube sound outlet 42 and the pressure relief hole are combined into a whole, the double effects of enhancing the watch bass effect and effectively adjusting the balance of the air pressure inside and outside the watch are achieved through one hole, the number of holes formed in the shell is reduced, and the appearance of a product is improved.

In some embodiments of the present application, a dust screen 50 is disposed at the sound outlet 42 of the inverter tube to prevent external foreign objects from entering the inverter tube 40 to affect the transmission of sound wave signals and affect the adjustment of the internal and external air pressure balance of the watch.

In some embodiments of the present application, the housing 11 includes an upper housing and a lower housing, and the upper housing and the lower housing can be connected into a whole by gluing, mechanical clamping, or the like. The upper shell is integrally formed with an upper concave type, the lower shell is correspondingly integrally formed with a lower concave type, and after the upper shell is connected with the lower shell, the upper concave type and the lower concave type are in butt joint to form the inverter tube 40, so that the inverter tube 40 can be conveniently processed and manufactured.

The specific shape of the sound wave transmission section 43 is not limited in the present application, and the direction of the sound wave transmission section 43 inside the housing 11 is specifically set according to the arrangement of the devices inside the housing 11.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
