In an embodiment, the distance between the first sound-emitting device and the first vibrating device is determined based on a sound pressure amplitude of a first sound wave radiated by the first sound-emitting device and a sound pressure amplitude of a second sound wave radiated by the first vibrating device.
In one embodiment, the first sound-emitting device comprises a speaker; the speaker includes: one of a moving coil speaker, a moving iron speaker, a piezoelectric ceramic speaker, or a MEMS speaker.
Referring to fig. 1, taking a mobile phone as an example, the first sound generating device is a speaker, the first vibrating device is a vibration exciter, the mobile phone includes a device housing composed of a front shell 1, a rear shell 2 and a frame 3, and a speaker 4, a vibration exciter 6 and at least one sound outlet 5 are installed on the top of the mobile phone. The speaker 4 communicates with the sound outlet hole 5. The vibration exciter 6 is in contact with and fixed to the rear case 2. The speaker may be a moving coil speaker, a moving iron speaker, a piezo ceramic speaker or a MEMS speaker. The vibration exciter may be a vibration generator such as an electromagnetic motor.
Fig. 2 is a schematic diagram illustrating far-field sound pressure reduction of an electronic device according to an embodiment of the present application. As shown in fig. 2, the first driving unit is an audio driving unit 1, and the second driving unit is an audio driving unit 2. The audio driving unit 1 transmits an electric signal 1 to the loudspeaker, and the loudspeaker radiates sound waves to the outside from the sound outlet hole by pushing air to vibrate; the audio driving unit 2 transmits the electrical signal 2 to the vibration exciter, and the vibration exciter generates sound by driving the rear shell to vibrate. Thus, the speaker and the vibration exciter are electrically connected to different drive units, respectively, so that the phases of sound waves emitted from the speaker and the vibration exciter are opposite. Therefore, the surrounding sound field is weakened, the sound leakage quantity around the user is reduced, and the communication privacy is improved.
Please refer to fig. 3, which is a schematic diagram illustrating a position of a sound generating element of an electronic device according to an embodiment of the present application. As shown in fig. 3, the speaker 4 is installed on the top of the mobile phone and communicates with the sound outlet hole 5. The sound outlet hole 5 is centrally arranged on the front side of the mobile phone and close to the top. The vibration exciter 6 is fixed in contact with the handset back case 2. Because the sound field obtained by superposing the two sound sources with opposite phases has directivity, for example, the vibration exciter 6 can be arranged on the central axis of the sound outlet hole 5, and the loudspeaker and the vibration exciter with equal sound pressure amplitude are selected, so that the maximum sound pressure radiated to the ear of a user can be ensured.
Please refer to fig. 4, which is a schematic diagram illustrating an ideal sound field direction of an electronic device according to an embodiment of the present application. As shown in fig. 4, the directivity of the ideal sound field is presented, and the sound pressure contour of the speaker marked by the upper circle and the sound pressure contour of the vibration exciter marked by the lower circle are known for the sound pressure of the user's ear:
for near field environments around the user, the speaker sound output port is closer to the ear hole than the vibration exciter due to the distance of the speaker sound output port from the ear hole. For example, if the sound outlet hole of the speaker is 10mm from the user's ear hole and the vibration exciter is 30mm from the user's ear hole, the vibration exciter will transmit 20log (30/10) ≈ 9.5dB more attenuation than the speaker. The sound pressure received by the ear canal of the user is mainly emitted by the loudspeaker and the counteracting effect of the vibration exciter is substantially negligible.
For the far-field environment around the user, for example, the position 50cm away from the user, the distances from the sound outlet hole of the loudspeaker to the vibration exciter are basically equal, and the attenuation values of the sound pressure levels emitted by the two sound generating units are equal, so that the sound pressure at the far-field position is the negative superposition of the sound pressure and the sound outlet hole, good sound wave cancellation can be realized, and the sound leakage amount radiated to the surrounding environment is reduced.
In an embodiment, the specification of the speaker device, the specification of the vibration exciter, and the installation position of the sound outlet and the vibration exciter together determine the offset of the vibration exciter to the sound pressure entering the ear of the user.
Further, the smaller the distance D between the vibration exciter and the sound outlet hole is, the more obvious the sound wave attenuation effect on a far field is, but the greater the sound pressure attenuation on the ear of a user is; conversely, the larger the distance D is, the weaker the sound wave attenuation effect on the far field is, but the reduction of the sound pressure into the ear of the user also becomes smaller; therefore, the magnitude of the sound pressure emitted from the speaker and the vibration exciter is determined according to the specifications of the actual speaker and the vibration exciter, and the magnitude of the distance D is determined comprehensively.
It should be noted that, the size and shape of the sound outlet are not limited in the present application, and any design manner of the size and/or shape that can satisfy the principle of the electronic device of the present application is within the protection scope of the present application.
It should be noted that the position of the sound output hole is not limited in the present application, and any design manner that can satisfy the position of the electronic device of the present application, other than the position of the sound output hole as described in the present application, is within the scope of the present application.
