For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0021] Some embodiments of the present disclosure provide a wearable device, comprising a carrier 5, a first audio assembly 1 and a second audio assembly 2, the carrier 5 is used to be worn on the head of a human body, and the carrier 5 can be glasses, a support of earphone or other structures, which can be stably worn on the head of a human body. The first audio assembly 1 and the second audio assembly 2 are both arranged on the carrier 5, and the first audio assembly 1 and the second audio assembly 2 are arranged at intervals. When a user wears the wearable device, the first audio assembly 1 and the second audio assembly 2 are respectively located at the ears of the user.

[0022] In some embodiments of the present disclosure, the first audio assembly 1 and the second audio assembly 2 both have a speaker and a shell, the speaker is arranged in the shell, the shell forms a front cavity and a rear cavity of the speaker, and the speaker can radiate sound waves outward after being driven. Optionally, the shell is connected to the carrier 5; or the shell constitutes part of the carrier 5; or part of the shell constitutes part of the carrier 5, and the other part of the shell is connected to the carrier 5.

[0023] Figure 1 An exploded view of the wearable device provided by some embodiments of the present disclosure is shown, Figure 3 A cross-sectional view of a partial structure of the wearable device provided by an embodiment of the present disclosure is shown. In some embodiments of the present disclosure, as shown in Figure 1 , Figure 3 The carrier 5 of the wearable device includes a first waveguide 3 and a second waveguide 4, the first audio assembly 1 has a first front cavity 121 and a first rear cavity 122, the second audio assembly 2 has a second front cavity and a second rear cavity, one end of the first waveguide 3 is coupled to the second rear cavity, the other end of the first waveguide 3 is close to the first front cavity 121, one end of the second waveguide 4 is coupled to the first rear cavity 122, and the other end of the second waveguide 4 is close to the second front cavity. When the speakers of the audio assemblies on both sides are driven in phase, the sound waves radiated by the first rear cavity 122 are superimposed with the sound waves radiated by the second front cavity after passing through the second waveguide 4, and the sound waves radiated by the second rear cavity are superimposed with the sound waves radiated by the first front cavity 121 after passing through the first waveguide 3.

[0024] In some optional embodiments, the first audio assembly 1 comprises a first speaker 11 and a first housing 12, the first speaker 11 is disposed in the first housing 12, and the first housing 12 forms a first front cavity 121 and a first rear cavity 122 of the first speaker 11; the first housing 12 is connected to the carrier 5 or constitutes a part of the carrier 5. The second audio assembly 2 comprises a second speaker and a second housing, the second speaker is disposed in the second housing, and the second housing forms a second front cavity and a second rear cavity of the second speaker; the second housing is connected to the carrier 5 or constitutes a part of the carrier 5, wherein one end of the first waveguide 3 is coupled to the second rear cavity, the other end of the first waveguide 3 is close to the first front cavity 121, one end of the second waveguide 4 is coupled to the first rear cavity 122, and the other end of the second waveguide 4 is close to the second front cavity; the first speaker 11 and the second speaker are driven in phase to make the first front cavity 121 and the second front cavity radiate the first sound wave, and the second sound wave radiated by the first rear cavity 122 and the second rear cavity is radiated outward via the second waveguide 4 and the first waveguide 3 respectively, so that at least part of the first sound wave is enhanced.

[0025] When the first speaker 11 and the second speaker are input with the same audio signal (i.e., the same sound source), the first sound wave radiated by the first front cavity 121 and the second front cavity is in phase, and the second sound wave radiated by the first rear cavity 122 and the second rear cavity is opposite to the phase of the first sound wave radiated by the first front cavity 121 and the second front cavity. After the second sound wave is delayed by the waveguide (i.e., the delayed wave), the phase of at least part of the frequency band in the first sound wave (i.e., the non-delayed wave) is obtained. Thus, the sound pressure of the part of the frequency band in the first sound wave can be enhanced.

[0026] Optionally, after the second sound wave radiated by the first rear cavity 122 and the second rear cavity is delayed by the waveguide, the sound pressure of the low-frequency part in the first sound wave radiated by the first front cavity 121 and the second cavity is enhanced, thereby achieving a full and powerful bass effect.

[0027] In some optional embodiments, the first waveguide 3 and the second waveguide 4 can be waveguides, and the waveguides have channels inside for guiding air flow.

[0028] In some embodiments of the present disclosure, the length of the first waveguide 3 and the second waveguide 4 can be determined by the following method:

[0029] The sound pressure amplitude P of the superposition of the same sound source delayed wave and the non-delayed wave 总 The calculation formula is as follows:

[0030] P 总 = 2 × P0× sin(2 × π × f × L / (V × 2));

[0031] wherein P0 is the amplitude of sound pressure of a single speaker, f is the frequency of the sound source, L is the difference in length of the transmission path of the sound waves emitted by the two speakers, and V is the speed of sound; wherein, since the path in the sound cavity (front cavity, rear cavity) is approximately equal to 1 / 40-1 / 100 of the length of the waveguide, it can be ignored, and the difference in length of the transmission path of the sound waves emitted by the two speakers can be substantially equivalent to the length of a single waveguide. When P 总 > P0, it can be considered that the amplitude of the superimposed sound pressure is greater than the original amplitude.

[0032] Some embodiments of the present disclosure provide a corresponding relationship of the superimposed frequency, the waveguide length, the lower limit frequency and the upper limit frequency, as shown in the following table.

[0033] Overlay frequency (Hz) Waveguide length (m) Lower frequency limit (Hz) Upper frequency limit (Hz) 609 0.279 202 1011 435 0.39 145 726 200 0.85 67 333 800 0.213 267 1333

[0034] In some embodiments of the present disclosure, the first waveguide 3 and the second waveguide 4 extend along the carrier 5. Optionally, the first waveguide 3 and the second waveguide 4 are at least partially located inside the carrier and extend along the carrier 5. And the length of the first waveguide 3 and the second waveguide 4 is greater than or equal to 20 cm and less than or equal to 60 cm, so that the sound pressure of the first sound wave in the range of 300 Hz to 800 Hz is enhanced, and the sound effect in the low frequency range is enhanced.

[0035] In some embodiments of the present disclosure, in order to ensure the audio effect, the size of the first waveguide 3 and the second waveguide 4 is designed so that the airflow velocity in the first waveguide 3 and the second waveguide 4 is less than or equal to 30 m / s. The airflow velocity in the waveguide is related to the effective radiation area of the speaker and the size of the channel in the waveguide. Optionally, for a selected speaker, the airflow velocity can be controlled by designing the cross-sectional area of the channel in the waveguide.

[0036] Some embodiments of the present disclosure provide a corresponding relationship of the effective radiation area of the speaker and the cross-sectional area of the channel of the waveguide, as shown in the following table.

[0037]

[0038]

[0039] Figure 7 The sensitivity curve of the audio assembly of the wearable device provided by some embodiments of the present disclosure is shown, Figure 7 wherein the length of the waveguide of the wearable device is 0.39 m, and the cross-sectional area is 9.6 mm 2 . Wherein, the vertical axis is the sound pressure level, unit: dB, the horizontal axis is the frequency, unit: Hz. By Figure 7 It can be clearly seen that after superposition, the low frequency effect of the wearable device is significantly improved.

[0040] In some optional embodiments, the cross-section of the channels within the first waveguide 3 and the second waveguide 4 can be circular, rectangular, racetrack-shaped, etc., with smooth channel flow and no sharp corners, thus avoiding sound wave reflection.

[0041] In some alternative embodiments, see Figure 1 and Figure 3 As shown, the audio component includes a first housing 12 and a second housing, both connected to a carrier 5.

The first sound wave radiated by the second sound outlet of the second housing will radiate along the channel inside the first waveguide 3 to the first sound outlet of the first housing 12. The sound outlet of the first waveguide 3 is close to the sound outlet of the first housing 12. The first waveguide 3 delays the phase of the low-frequency part of the sound wave radiated by the second rear cavity of the second speaker so that it is in phase with the low-frequency part of the sound wave radiated by the first front cavity 121 of the first speaker 11, thereby achieving the effect of sound pressure superposition. Similarly, the sound inlet of the second waveguide 4 can connect to the first sound outlet 124 on the first housing 12. The second sound wave radiated by the first sound outlet 124 of the first housing 12 will radiate along the channel inside the second waveguide 4 to the second sound outlet of the second housing. The sound outlet of the second waveguide 4 is close to the sound outlet of the second housing. The second waveguide 4 delays the phase of the low-frequency part of the sound wave radiated by the first rear cavity 122 of the first speaker 11 so that it is in phase with the low-frequency part of the sound wave radiated by the second front cavity of the second speaker, thereby achieving the effect of sound pressure superposition. One ear of the user wearing this wearable device can hear the sound waves radiated by the first front cavity of the first speaker 11 and the second rear cavity of the second speaker, and the other ear of the user can hear the sound waves radiated by the second front cavity of the second speaker and the first rear cavity of the first speaker 11.

Similarly, the extension direction of the sound outlet of the second waveguide 4 is substantially perpendicular to the extension direction of the second escape hole, and the sound waves radiated by the first back cavity in the second waveguide 4 will be released from the sound outlet of the second waveguide 4 to superimpose with the sound waves radiated from the second sound hole at the second escape hole 513.
