As shown in fig. 1 to 7, the present utility model proposes an electronic device 100 including a double-sided sound generating unit 10, a treble sound generating unit 20, and a housing 30, wherein the double-sided sound generating unit 10 includes a first sound generating unit 11 and a second sound generating unit 12 disposed opposite to each other; the operating frequency band of the treble sound generating unit 20 is greater than 2000Hz; the double-sided sound generating unit 10 and the treble sound generating unit 20 are both accommodated in the casing 30, so that the structural compactness is improved, and the casing 30 is provided with a first sound hole 31 communicated with the first sound generating unit 11, a second sound hole 32 communicated with the second sound generating unit 12, and a third sound hole 33 communicated with the treble sound generating unit 20.

The electronic device 100 of the present utility model may be a mobile phone, a tablet, a computer, etc., where the mobile phone is a straight screen mobile phone or a folding screen mobile phone. The electronic device 100 of the present embodiment is illustrated as a mobile phone.

In an embodiment, the diaphragm assembly of the first sound generating unit 11 is a first diaphragm assembly 111, and the diaphragm assembly of the second sound generating unit 12 is a second diaphragm assembly 121. The first sound generating unit 11 and the second sound generating unit 12 in the double-sided sound generating unit 10 are disposed opposite to each other, i.e., the first diaphragm assembly 111 and the second diaphragm assembly 121 are disposed opposite to each other. In an embodiment, the sound emitting directions of the first diaphragm assembly 111 and the second diaphragm assembly 121 are opposite, for example, the first diaphragm assembly 111 emits sound forward and the second diaphragm assembly 121 emits sound backward. In another embodiment, the sound emitting direction of the first sound emitting unit 11 and the sound emitting direction of the second sound emitting unit 12 in the double-sided sound emitting unit 10 are the same, i.e. the sound emitting directions of the first diaphragm assembly 111 and the second diaphragm assembly 121 are the same, and the first diaphragm assembly 111 and the second diaphragm assembly 121 vibrate in the same direction. For example, the first diaphragm assembly 111 and the second diaphragm assembly 121 both sound forward at the same time, or the first diaphragm assembly 111 and the second diaphragm assembly 121 both sound backward at the same time.

The sound emitting area of the first diaphragm assembly 111 and the sound emitting area of the second diaphragm assembly 121 may be the same or different. In an embodiment, the sound emitting area of the first diaphragm assembly 111 is the same as the sound emitting area of the second diaphragm assembly 121. The housing 30 is provided with a first sound hole 31, a second sound hole 32 and a third sound hole 33, the first sound generating unit 11 generates sound through the first sound hole 31, the second sound generating unit 12 generates sound through the second sound hole 32, and the third sound generating unit generates sound through the third sound hole 33.

The electronic device 100 of the present utility model has two modes of operation, namely a speaker mode (SPK mode) and a receiver mode (RCV mode).

When a call is to be answered, the electronic device 100 can be in RCV mode, and the first sound generating unit 11 and the second sound generating unit 12 of the double-sided sound generating unit 10 vibrate in the same direction to generate sound waves with the same amplitude and opposite phases, so as to form a dipole effect and improve call privacy. In addition, the high-frequency sound generating unit 20 works in a working frequency band larger than 2000Hz, can offset the superimposed sound field of the electronic equipment 100 after the far field is 2000Hz, improves the middle-high frequency offset effect, ensures that the far field offset bandwidth of sound can be larger than 2000Hz, widens the sound offset frequency band, greatly reduces middle-high frequency sound leakage and further improves the call privacy. It should be noted that, the superimposed sound field referred to in the present utility model includes both an enhanced sound field and a cancel sound field.

When the external sound is required, the electronic device 100 can be in the SPK mode, the double-sided sound generating unit 10 and the high-pitch sound generating unit 20 work, the double-sided sound generating unit 10 is used as a low-pitch sound generating unit and works in frequency division with the high-pitch sound generating unit 20, so that the frequency band of the electronic device 100 is effectively widened, and the tone quality is improved.

Specifically, when the electronic device 100 is in the SPK mode, the two-sided sound generating unit 10 and the treble sound generating unit 20 operate in frequency division, the frequency division point is set after the front cavity resonant frequency Fh of the two-sided sound generating unit 10, and since the two-sided sound generating unit 10 includes the first sound generating unit 11 and the second sound generating unit 12, the front cavity resonant frequency of the first sound generating unit 11 is Fh1, the front cavity resonant frequency of the second sound generating unit 12 is Fh2, a larger front cavity resonant frequency is selected as the front cavity resonant frequency Fh of the two-sided sound generating unit 10, if Fh1 is less than Fh2, fh=fh2, the frequency division point frequency is not less than Fh, and the frequency division point frequency cannot be the resonant frequency F0 of the treble sound generating unit 20, that is, the frequency division point frequency is greater than Fh and not equal to F0. When the driving frequency is less than or equal to the frequency of the frequency division point, the double-sided sound generating unit 10 reversely vibrates to generate sound waves with the same phase, and the sounds generated by the first sound holes 31 and the second sound holes 32 are mutually overlapped; when the driving frequency is greater than the division point frequency, the treble sound generating unit 20 operates. That is, after framing, the transient signal is played back with a low frequency signal less than the crossover point frequency and a high frequency signal greater than the crossover point frequency. Although the double-sided sound generating unit 10 and the treble sound generating unit 20 are divided in the frequency domain, since there are both a low frequency signal and a high frequency signal in the reproduced frame signal, the double-sided sound generating unit 10 and the treble sound generating unit 20 operate together in the time domain.

It will be appreciated that the front cavity resonant frequency Fh may be 6000Hz, and the crossover point frequency is greater than 6000Hz, and when the driving frequency is greater than the crossover point frequency, the treble sound generating unit 20 operates without reducing the loudness of the electronic device 100.

Setting the upper limit frequency of cancellation of the treble sound generating unit 20 to Fc, that is, the cancellation frequency of the treble sound generating unit 20 to 2000Hz to Fc, it is necessary to ensure that the resonance frequency F0 < 2000Hz of the treble sound generating unit 20, or F0 > Fc.

According to the electronic equipment 100, the double-sided sound generating unit 10 and the high-frequency sound generating unit 20 are arranged, the first sound generating unit 11 and the second sound generating unit 12 in the double-sided sound generating unit 10 are arranged back to back, the working frequency band of the high-frequency sound generating unit 20 is larger than 2000Hz, the first sound hole 31, the second sound hole 32 and the third sound hole 33 are formed in the shell 30, the first sound generating unit 11, the second sound generating unit 12 and the high-frequency sound generating unit 20 can generate sound through the first sound hole 31, the second sound hole 32 and the third sound hole 33 respectively, the superimposed sound field after the far field of the electronic equipment 100 is 2000Hz can be counteracted, the middle-high frequency counteracting effect is improved, the far field counteracting bandwidth of the sound can be larger than 2000Hz, the sound counteracting frequency band is widened, middle-high frequency leakage is greatly reduced, the call privacy is further improved, and the frequency band of the electronic equipment 100 can be effectively widened, and the tone is improved.
