Please continue to refer to Figure 1. Taking a mobile phone as an example, the first sound-generating device is a speaker and the first vibration device is a vibration exciter. The mobile phone includes an equipment housing composed of a front shell 1, a back shell 2 and a frame 3. And a speaker 4, a vibration exciter 6, and at least one sound hole 5 are installed on the top of the mobile phone. The speaker 4 is connected with the sound hole 5 . The vibration exciter 6 is in contact with the rear case 2 and fixed. The speaker can be a dynamic speaker, a moving iron speaker, a piezoelectric ceramic speaker or a MEMS speaker. The vibration exciter may be a vibration sounder such as an electromagnetic motor.

Figure 2 is a schematic diagram of far-field sound pressure attenuation of an electronic device according to some embodiments of the present disclosure. As shown in FIG. 2 , the first driving unit 20 is implemented by, for example, an audio driving unit, and the second driving unit 30 is implemented by, for example, an audio driving unit. In the following description, the first audio driving unit may be directly used to represent the first driving unit 20 and the third driving unit. The second audio driving unit represents the second driving unit 30 . The first audio drive unit transmits the first electrical signal to the speaker 4. The speaker 4 vibrates the air and radiates sound waves to the outside through the sound hole 5. The second audio drive unit transmits the second electrical signal to the vibration exciter 6. The vibration exciter 6 produces sound by driving the rear shell 2 to vibrate. As a result, the speaker 4 is electrically connected to the first drive unit 20, and the vibration exciter 6 is electrically connected to the second drive unit 30. The driving of different drive units can make the sound waves emitted by the speaker 4 and the vibration exciter 6 be in phase with each other. opposite. This weakens the surrounding sound field, reduces the amount of sound leakage around the user, and improves call privacy.

Figure 3 is a schematic diagram of the position of a sound-generating element of an electronic device according to some embodiments of the present disclosure. As shown in Figure 3, the speaker 4 is installed on the top of the mobile phone and communicates with the sound hole 5. The sound hole 5 is centrally located on the front of the mobile phone and close to the top. The vibration exciter 6 is in contact with the back shell 2 of the mobile phone and fixed. Since the sound field after the superposition of two opposite-phase sound sources has directivity, for example, the vibration exciter 6 can be arranged on the central axis 50 of the sound hole 5, and a speaker and a vibration exciter with equal sound pressure amplitudes are selected, so that It can ensure the maximum sound pressure radiated to the user's ears.

Obviously, the above-mentioned speakers and sound holes can also be arranged in other positions of the mobile phone, for example, they are both arranged at the top of the mobile phone near the sides, or the speakers can be arranged at other positions of the mobile phone, for example, the speakers are installed at the top of the mobile phone near the sides. , the sound hole is centrally arranged on the front of the mobile phone and close to the top, and the speaker and the sound hole are connected through the sound channel.

FIG. 4 is a schematic diagram of the sound field direction of an electronic device according to some embodiments of the present disclosure. As shown in Figure 4, the directivity of the sound field is shown. Regarding the user's ear sound pressure, it can be known from the speaker sound pressure contours marked in the circle above and the sound pressure contours of the vibration exciter marked in the circle below:

For the near-field environment around the user, the distance between the sound hole of the speaker and the ear hole is closer than that of the vibration exciter. For example, if the distance between the speaker's sound hole and the user's ear hole is 10mm, and the distance between the vibration exciter and the user's ear hole is 30mm, then the sound pressure level transmitted by the vibration exciter to the user's ear hole will be attenuated 20log(30/10)≈9.5dB more than that of the speaker. Therefore, the sound pressure received by the user's ear holes is mainly emitted by the speaker, and the offset effect of the vibration exciter can basically be ignored.

For the far-field environment around the user, for example, at a position 50cm away from the user, the distance to the speaker sound hole and the vibration exciter is basically the same, and the sound pressure level attenuation values emitted by the two sound-emitting units are equal, so the far-field The sound pressure at the location is the negative superposition of the two, which can achieve sound wave cancellation and reduce the amount of sound leakage radiated to the surrounding environment.

In one embodiment, the specifications of the speaker device, the specifications of the vibration exciter, and the installation positions of the sound outlet and the vibration exciter jointly determine the impact of the vibration exciter on the sound pressure in the user's ears. Offset size.

Furthermore, the smaller the distance D between the vibration exciter and the sound hole, the more obvious the attenuation effect on far-field sound waves, but also the greater the attenuation of the user's ear sound pressure; conversely, the greater the distance D, the greater the attenuation effect on far-field sound waves. The weaker the sound wave attenuation effect, the smaller the attenuation of the sound pressure in the user's ears; therefore, the sound pressure amplitude emitted by the speaker and vibration exciter can be determined based on the actual specifications of the speaker and vibration exciter to comprehensively determine the distance D size.

It should be noted that the present disclosure does not limit the size and shape of the sound hole, and any design method with a size and/or shape that can meet the principles of the electronic device of the present disclosure is within the scope of protection of the present disclosure.

It should be noted that the present disclosure does not limit the position of the sound hole, except for the position of the sound hole listed in the text.
